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
