Configuring UFH actuator

When thermostat’s preset is set to P3 (Hydronic Underfloor) and it is connected with Wiser under floor heating (UFH) actuator, pairing process continues to configure UFH system. Thermostat will use UFH to control room temperature.

The thermostat can also be used as a temperature sensor and a temperature set point selector for other heating devices like 16A Relay or iTRV's.

NOTE: Refer, pairing the device.

Assign a room to the thermostat once it has been paired and then tap Next to configure UFH.
Tap Output Device (A) for slide up menu and select the UFH (B) from the list which is connected to the thermostat.

NOTE: Built-in relay is selected by default as the output device, there are no other settings for it.
Tap on Channels (C) and select the channel which controls the room where thermostat is located.
Enable toggle switch (D), if you want monitor the floor temperature using UFH floor sensor.
NOTE:
- To change the UFH channel room refer Assigning a channel to the room.
- Only one UFH floor sensor can be assigned to a room if you want to update refer Setting Floor Sensor Location.
Tap Submit.

The thermostat is now listed on the Control tab under the All and the specific room tabs.

IMPORTANT: If cooling input is enabled in UFH make sure in Room Setting > Excluded From Cooling toggle switch is On. This can be useful if there are areas in a building that do not require cooling, such as storage rooms or unoccupied spaces. Refer UFH Cooling input.
