New Product Releases

/in /by

Priding ourselves on innovation and American assembly ICM Controls has hit the ground running in 2025. With over three new products launched this year we’d like to take a step back and appreciate how far we’ve come in two shorts months.  

ICM Controls caters to both OEMs and the aftermarket allowing us flexibility in what we can offer to our customers to best suit their needs. Dedicated to innovation throughout the entire process from design the conception, ICM Controls has been able to manufacture controls to help meet your needs. 

Looking back on January 

In January ICM Controls launched the ICM279. A form, fit and function air handler replacement board for the Carrier/ICP brand. This control design allows it to be a fast drop-in option with OEM mounting and wiring for PCB blower motors. Its heavy-duty output delay and internal short-cycle protection are some of its key features and benefits.

Leaping into February  

With great success at the beginning of 2025, ICM Controls has kept the momentum going! In February we developed a device that offers surge protection and line voltage monitoring in one easy-to-install solution. 

The Sentry 3N1 launched at the beginning of February. This device was an eye jerk-er and topic of interest for almost all attendees at the AHR25 Conference. We are pleased to have officially launched this product and look forward to its future success.  

A brief overview of the Sentry 3N1, why you need it and what it can truly do for you.  

What is the Sentry 3N1?  

The Sentry 3N1 combines the benefits of an ICM517A single-phase surge protection device, and a ICM492 single-phase voltage monitor into one easy to install solution. It also provides technicians and homeowners a convenient way to break the power using an onboard disconnect breaker (also serving as a secondary safety). 

The Sentry3N1 protects against both power surges and over/under voltage issues that can cause damage to circuit boards and motors in residential and commercial single-phase 208/240 VAC HVAC/R equipment. 

The Sentry 3N1 is equipped with an ICM517A which is built to withstand the high impact of major surge events (100Ka). This kind of protection helps to ensure our equipment can maintain the effects of a surge, essentially providing us with a low-cost insurance policy for our appliances. In addition, to surge protection the Sentry 3N1 also provides line voltage monitoring of single- phase devices. Monitoring line voltage allows an anti-short cycle delay to take place, preventing the compressor and reversal of scroll compressors, giving precise control over the output relay.

How Cold Weather Can Affect Your Everyday Appliances

/in /by

The low temperatures most of us are experiencing throughout the United States can cause a threat to not only ourselves but also to our everyday appliances. These fridged temperatures we’re facing can cause appliances to not only work less efficiently but can also lead to freezing, cracking and/or even an explosion. During the months of November – April it’s important to take extra precaution to help protect your appliances from unforeseen damaged due to the cold.

Here’s some insight as to how the cold affects appliances such as washing machines and refrigeration, and what measures we can take to get the most out of our equipment during these cold days ahead.

 

How Cold Weather Affects Refrigeration

Our fridges and freezers are one of the most used appliances within the household. However, with most households having an average of 2.55 people in them it can be hard to fit all your groceries into one place. Therefore, some of us also have a refrigerator or freezer in our garages or basements to help hold the overflow items. Although, it is nice to have some additional storage space, it’s also important to keep in mind that if temperatures drop below 60 – 80 degrees Fahrenheit your fridge might not cycle as frequently. This is mainly due to the thermostat on the refrigerator not calling for the proper cooling and defrost cycles to take place, which could ultimately lead to your refrigerator or freezer to stop working. If you can regulate your temperatures in these colder areas of your home, it could save you from having to repair and/or replace these larger appliances.

 

How cold weather affects washing machines

For most of us located near the ICM Controls headquarters of Syracuse, NY, we are facing temperatures as low as -1 this week. Did you know that these extremely low winter temperatures could affect how we do laundry? If you’ve done your wash recently and seem to think the job is just not getting done, you could be right! Laundry detergent requires water to be at least 60 degrees Fahrenheit, if not warmer. If the temperature in your washing machine is below 60 degrees, there’s a chance that the detergent is not dissolving properly. Although, the “cold” setting helps save money and energy it’s important to understand what setting are needed to ensure your detergent is dissolving based on your specific weather conditions. Otherwise, you’ll be using more water than necessary without achieving the end goal of having clean clothes. All in all, if you’re experiencing negative temperatures outside it might be beneficial to rely more on the “warm” or “hot” water setting to effectively and efficiently wash your clothes.

Thank you for reading our tips and tricks!

Heat Pumps and Their Benefits During the Winter Season

/in /by

What is a Heat Pump?
A heat pump is a device that is typically fixed outside of your home and is designed to keep your house at a comfortable temperature by moving warm air into your home in the winter and out during the summer. It takes in thermal energy and transfers it from a cold state to a hot state (in the winter months and the opposite in the summer) using a refrigeration cycle.

How does a Heat Pump Work?
Heat pumps take in heat from the air or ground, also known a thermal energy and transfer it into a heat exchanger (tube and fin, shell and tube, or braze plate) that contains liquid refrigerant. The refrigerant works to absorb the outdoor heat and transfer a liquid state into a low-pressure, low-temperature gas.

 

See image below to view the complete cycle:

Different Types of Heat Pumps:
There are roughly four heat pump options to choose from. These include: air-to-air, air-to-water, ground source and water source heat pumps. Below we’ll look at how air-to-air and air source heat pumps work.

Air-to-air heat pumps are one of the most common heat pumps used today. They operate similar to an air conditioning unit. Let’s take a look into some of the options below.

When set in a heating mode the cool air is brought in through the compressor, where refrigerant is kept. This then makes its way into the indoor heat exchanger where cool air is blown in removing some of the thermal energy and providing heat into the room. As this heat is removed, the refrigerant will condense into a liquid and goes into the indoor heat exchanger. This heat exchanger transforms the liquid to a warm gas. The liquid refrigerant will then make its way through the non-return valve (expansion valve), filter, drier and another non-return valve (expansion valve), leaving the refrigerant at a low pressure, low temperature state. The cold refrigerant is then put through the outdoor heat exchanger which blows ambient air over the mixture, warming it up to a boil carrying away the thermal energy.

Air-to-Water Heat Pumps work very similar to a “air-to-air” heat pump but without the reversing valve. The high pressure and high temperature refrigerant passes through a plate heat exchanger and enters into the hot water tank. Cool water enters the heat exchangers through the tank and as it passes through the heat exchanger it absorbs heat from the hot refrigerant and leave the at a higher temperature. As the refrigerant gives up its heat to the exchanger it leaves cool. It then passes through the filter, sight glass, and expansion valve. This now liquid/vapor mixture passes through the outdoor heat exchanger (where ambient air is entered into the system) causing the refrigerant to boil, this refrigerant vapor is then sucked back into the compressor to repeat the cycle. The hot water tank will then push hot water throughout the radiator, sinks and showers throughout.

Is it Too Cold for a Heat Pump to Work in the Winter?
Contrary to most beliefs, air source heat pumps work very well in cooler climates. At about 25 degrees, most heat pumps when installed correctly will still be more efficient than your tradition furnace or boiler.

Things to Consider:
1. Heat pumps don’t burn fossil fuel to create heat, which will help reduce your monthly gas bill as well as assist in preserving our environment.
2. Heat pumps have one of the lowest carbon emissions of any heat source
3. Heat pumps are designed to work efficiently in cold climates such as New York
4. Most heat pumps also double as a cooling system in the summer

ICM2818 & ICM2820: Product Spotlight of the Month

This month’s product spotlights are the new ICM2818 & ICM2820 form, fit and function direct replacement furnace boards for manufactured housing.

 

The ICM2818 and ICM2820 are both furnace control board which are designed to control the functions of the furnace including the induced draft blower, circulator blower, gas valve, ignitor, and flame sensor based on inputs from a thermostat and various sensors in the furnace. The ICM2818 and ICM2820 controls will also detect faults and communicate the faults while in service and display the faults through its on-board LED as well as employ a timed safety lockout when the conditions warrant.

 

How these new furnace Control Board Works:

The thermostat first calls for heat by energizing the “W” terminal. The control energizes the induced draft motor and waits for the pressure switch to close and runs the inducer for a 45 second pre-purge time. After the inducer pre-purge, the control energizes the Hot Surface Ignitor. After the Hot Surface Ignitor warm up period, the control energizes the main gas valve. Once the burner lights, flame must be proven by the flame sensor and the Hot Surface Ignitor turns off. Once the flame is proven, the control begins a 30 second On-delay then energizes the main blower at the HEAT speed. When the thermostat demand for heat is satisfied, the control de-energizes the gas valves. The inducer output remains on for a 30 second post-purge period. The indoor blower motor is de-energized after a 120 second blower off delay. Upon a fan call (G) from the thermostat, the cool speed blower will activate.

 

Features that make the ICM2818 & ICM2820 stand out:

  • Controls furnace operation including the function of the induced draft blower, circulating blower, ignition sequence, gas valve, and flame sense
  • Monitors system safeties to properly lock out operation when there is a safety fault
  • Detects and communicates faults using diagnostic LED to aid troubleshooting
  • Form, fit, and functional replacement for the OEM boards listed as a cross

Introducing the NEW ICM2818 & ICM2820

/in /by

Ready, Set, Replace

With the colder weather just around the corner ICM Controls wants you to be prepared for what’s in store. As we turn our furnaces on for the first time this year it’s important to pay attention to any LED lights that may be blinking on your current control board. This light can provide a first sign that your circuit board needs to be replaced soon.

 

Two types of furnace control boards

There are two types of furnace control boards used in the market today, a simple ignition control module and an integrated furnace control board. A simple ignition control module controls the gas valve, igniter and the flame sensing circuit while, the integrated furnace control boards encompass all the above and more, it also controls the furnace blower.

 

Understanding the Importance of a Furnace Control Board

As the temperatures begin to lower throughout the northern region of the United States furnaces will begin to run. Many of us think of a furnace as a large electrical piece of equipment however, did you know that this large piece of equipment is essentially being operated by a small furnace control board? The furnace control board is the brains of the operation, it tells the furnace when to kick the gas on, triggers the blower motor to turn on and moves air throughout the furnace to ensure it does not overheat, and finally, when your thermostat meets optimal temperature the control board will indicate when to turn off the gas too.

 

Knowing when to Replace Your Furnace Control Board

A furnace control board is a very integral part of the system, and it’s important to know when a replacement is needed. In most cases a furnace control board will have an LED indicator light that will notify you if something is wrong. If the control board’s diagnostic light is blinking, this means your control board has detected an issue with its circuit. If you see visible damage to the board as well such as burn marks or bad wires, this is also an indicate that the board needs to be replaced.

 

What Replacement Can I Use?

Replacements will vary on the type of furnace you own, and ICM Controls offers a quick reference guide for your convenience to assist in finding the best option to suite your needs. However, today we will be highlighting two of our newly launched direct replacement furnace boards for manufactured housing, the ICM2818 & ICM2820. These are direct replacements for the Nordyne/Nortek™ Furnace Models M1M (ICM2818) and MG1E (ICM2820).

  • Provided are the main features of these furnace boards:
    • Controls furnace operation including the function of the induced draft blower, circulating blower, ignition sequence, gas valve, and flame sense.
    • Monitors system safeties to properly lock out operation when there is a safety fault
    • Detects and communicates faults using diagnostic LED to aid in troubleshooting

ICM325A: Product Spotlight of the Month

This month’s product spotlight is the ICM325A single-phase Universal Head Pressure Control. This device is designed to control head pressure on a heat pump or HVAC unit by controlling the condenser fan speed, thus allowing the heat pump or air conditioner to operate even when the temperature outdoors is too low for normal operations.

 

Head Pressure Control in Low Ambient Conditions

As the weather begins to drop throughout most of the United States it’s important to ensure our HVAC systems are prepared for this change too. To help our HVAC systems in these cooler climates it’s important to keep your high side pressure up. If head pressures fall too low there will not be enough pressure to operate the system properly, which could lead to short cycling. It is recommended that if you’re running a unit in low ambient conditions that you also have a low ambient control installed to help keep these pressures from falling too low. Without a low ambient control in place, you could run into costly repairs, poor cooling and wasted energy.

 

Stay One Step Ahead with ICM325A

Designed to control head pressure by controlling the condenser fan speed the ICM325A is a useful tool this shoulder season. Using a probe, it senses the condenser temperature or pressure and varies the power output to the condenser fan motor which will cause it to slow down or speed up, ensuring that the unit operates properly.
