Overview
This is the genuine OEM ICP VariTech communicating thermostat (part number 1064095, TSTAT VARITECH SB) used with the ICP/Tempstar/Heil YH024GC system. Unlike a basic 24V thermostat, the VariTech control communicates digitally with the indoor and outdoor equipment to manage staging, fan speed, and system diagnostics over a low-voltage communicating bus. It serves as the user interface and the brain of the comfort system, sending setpoint and mode information to the equipment and reading back fault codes. Common failure symptoms include a blank or frozen display, loss of communication with the equipment, intermittent loss of heating or cooling, or repeated communication fault codes at the furnace or air handler.
