The Genius Hub can control wet underfloor heating (UFH), and there are two main types of underfloor heating.
Single Zone of wet Underfloor Heating
If you have a single zone of underfloor heating, you do not have an 'underfloor heating wiring centre'. (A wiring centre is a box that is wired into your existing room thermostats and the valve actuators on the underfloor heating manifold, the metal part that the water flows through.)
Set the zone up as an Underfloor zone, and use an Electric Switch to control the manifold pump/zone valve.
Multiple Zones of wet Underfloor Heating
If you have multiple zones of underfloor heating, you will have an 'underfloor heating wiring centre'. There are two main types of wiring centre: 230V and 24V.
You will need to check the compatibility of the wiring centre before the system is installed. Most common types are listed on our support pages.
-
230V wiring centre: set up one Underfloor zone for each room you want to control, with one Electric Switch or Powered Room Thermostat per zone.
-
24V wiring centre: use an Electric Relay or Single Channel Receiver for each zone instead of the Electric Switch.
When the underfloor heating wiring centre was installed, a cable should have been run from the wiring centre to the relevant boiler/zone valve, so that the system automatically calls for heat. If this was not installed, you should add a group zone so the Genius Hub can switch the heat source on for the underfloor heating (see bringing on the boiler with an Underfloor zone).
