Select DHW Demand prompts the installer to select how a DHW Demand is generated. There are two Select DHW Demand options,
among which the installer must make a selection.
When Thermostat is selected in Select DHW Demand, a domestic hot water call from an aquastat or dry contact switch will enable
the WaterMaster with a xed setpoint for a domestic hot water call..
When Sensor is selected in Select DHW Demand, it requires the use of an optional Indirect Water Heater Sensor. The WaterMaster moni-
tors the DHW storage temperature and generates a DHW call whenever the temperature drops below the DHW storage setpoint by 3°C.
