About the device

The Wiser Underfloor Heating Controller / Connection Strip (hereinafter called Underfloor Heating / UFH) is used to control thermal actuator valve heads to regulate the flow of hot water in the underfloor pipes.

The UFH is available in the following versions:

UFH Heat/Cool
UFH Heat
UFH Heat/Cool 24 V

The UFH Heat/Cool and UFH Heat/Cool 24 V can also be used to control a heat pump or a boiler. The UFH should only be used with hydronic UFH systems. It works in conjunction with the Wiser Hub and Wiser room thermostats, and it controls the temperature for individual rooms/zones.

TIP: There are total 6 channels available on Underfloor Heating, based on your rooms/zones requirement select the channel:

1/2 channel: you can use it for a large room to control 4 thermal actuators valve heads to supply hot water.
3/4 channel: you can use it for a medium room to control 2 thermal actuators valve heads to supply hot water.
5/6 channel: you can use it for a small room to control a thermal actuator valve head to supply hot water.

With mixed systems (UFH and radiators) Wiser radiator thermostats can be added, and in this way a complete hydronic heating system can be controlled. The system is simple to expand: 2 further Wiser Connection Strips (and optionally radiator thermostats) can be added.
1x UFH max. 6 rooms/zones
2x UFH max. 12 rooms/zones
3x UFH max. 16 rooms/zones

Features of the Underfloor Heating:

Remotely control Underfloor Heating using the Wiser Home app.
Boost the room temperature using the ELKO - Wiser Room Thermostat center button.
