The Genius Hub system can control a wide variety of wet underfloor heating, in terms of the configuration of the underfloor heating, the floor covering and the hardware that is already part of the underfloor heating system. It can also control electric underfloor heating with the Powered Room Thermostat.

...

The Single Channel Receiver is rated to 3A maximum. It can only be used to switch a zone valve, underfloor heating wiring centre or actuator and not a circulation pump. Controlling Wiring to a circulation pump directly will result in damaging the receiver units, voiding the warranty! The Electric Relay is rated to 11A maximum. The Electric Switch is rated to 13A maximum. The Powered Room Thermostat is rated to 16A maximum.

Info
  • There is no requirement for a programmer to be connected to the underfloor heating wiring centre. All of the control should be done from the Genius Hub receiver units. See wiring diagrams provided by the underfloor heating manufacturer to confirm the wiring in this installation manual. 
  • Using the appropriate wiring, as in accordance with BS7671 (or newer if such exists).
  • Our Underfloor Wiring Centre terminals for the Manifold Pump and Underfloor Zone Valve are volt-free. See our wiring diagrams for how to connect to a 230v Pump/Zone Valve.


Warning

Do not attempt to wire in your Receiver Unit if you are not 100% sure that you know what you are doing. Danger of electric shock! All wiring should conform to IEE regulations. The boiler, underfloor heating and wiring for the Receiver Unit must be electrically isolated before you commence work on wiring the Receiver Unit!

  1. The Powered Room Thermostat fits into a standard 1-gang pattress, we recommend approximately 40mm deep.
    1. If you are using a flush mount pattress it should screw in without any problems.
    2. If you are using a surface mount pattress, you may need to use the 2 spacers to bring the Powered Room Thermostat closer to the edge of the pattress.
  2. Wire in the Temperature Probe or link provided into the 'Floor Sensor' terminals. (If using an existing probe, it must be 10kΩ at 25°C)
  3. Install the pattress into the room the Powered Room Thermostat is going to control.
    1. If using the floor probe, consider how this is going to get out of the pattress and it will be installed into the floor layer/onto the pipework of the wet underfloor.
  4. Wire in the mains power and the heating load to the Powered Room Thermostat.
  5. To screw the Powered Room Thermostat to the pattress, first remove the screen by pushing a small flat-bladed screwdriver into the flat gap on each side of the screen. This will release the 2 spring clamps, and the screen and frame will become loose.

  6. Screw the Powered Room Thermostat to the pattress. Due to the cutouts to the side of the screen of the PRT, it can either be screwed directly to the pattress, or the screws can be mostly screwed in first and the Powered Room Thermostat placed over the screwheads and rotated.
    1. See 1.b if using a surface mount pattress, taking care to place the spacers between the device and the pattress.

  7. Place the frame on the Powered Room Thermostat and push the screen in place to secure the two parts to the main unit, ensuring the logo is at the bottom-left of the screen. 
  8. If using the Floor Probe, fit this into the floor layer before powering on the Powered Room Thermostat.

In normal operation there will be no lights when the unit is off and one red light to the bottom-right of the display when heating.
