TRACER CH532 offers the possibility to offset cold and/or hot water setpoints according to ambient air temperature.

The automatic setpoint reset program will allow you to change the water temperature setpoint (cooling and heating mode) with the ambient temperature. This function can be used in conjunction with the external setpoint reset function.
