Page 12 Relay Board I/O Description Note: All inputs require 24VAC (ungrounded side) power to operate and a 24V COM common connected. THERM and U1 - Connection terminals for the tank thermistor sensor used in the DHW control mode. Only one should be connected at a time. U2 - Connect to the CN27 Water Tank Temp input on main board or the cable marked “Water Tank”.
Page 13 ...cont. DHW - Supplying 24V to the DHW terminal will enable HP DHW (Hot Water) mode. When DHW mode is enabled the heat pump will monitor the temperature of the connected external temperature sensor. Regardless of the other heating or cooling demands present, when the temperature of the sensor drops below the DHW mode set point plus the set differential the heat pump will activate it’s the...
