3. Typical Applications
3.1 Space Heating Only
The room thermostat is used as a switch. When there is a heating request from the room thermostat, the
unit operates to achieve the target water temperature set on the Wired controller. When the room temperature
reaches the thermostats set temperature, the unit stops.
When the heating terminal uses floor heating and Heating radiator at the same time, the two ends of the
floor heating and low temperature radiator require different working water temperatures. In order to meet these
two different working water temperatures at the same time, it is necessary to install a mixing valve and a mixing
water pump at the inlet and outlet of the floor heating , The outlet water temperature of the unit is set to the
water temperature required by the heating radiator, and the water mixing valve and water mixing pump are set
to reduce the inlet water temperature of the floor heating.
