Rinnai CHP3PHAUX is a 3-phase auxiliary relay box designed for use with Rinnai commercial heat pump and electric tank systems. It supplements heat at low ambient temperatures and interlocks with the heat pump to operate only under low ambient or fault conditions. The device receives a "close" signal from the heat pump and activates the auxiliary booster when the ambient temperature falls below 5°C. The auxiliary booster remains active until the ambient temperature reaches above 7°C. In case of heat pump fault, the auxiliary booster operates instead of the heat pump until the fault is cleared.
