🛠️ HVAC Depot Pro Tip: Power Cycling and Diagnostics

iComfort control boards often store fault codes in their EEPROM. When replacing this board, make sure to properly power cycle the entire HVAC system (turn power off at the breaker for several minutes) after installation to clear old codes and allow the new board to initialize correctly with the system's other communicating components.
