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.

...

  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 20kΩ 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 case 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.

Electric Switch (Switched Live connections, or Single Zone / Underfloor Pump)

...

  1. Always ensure that the boiler, underfloor heating and wiring for the Electric Relay is electrically isolated before you commence work on any wiring.
  2. Break out the relevant section of a 1-gang pattress for the wiring and fix the pattress to the wall. It is recommended that a 40mm pattress is used.
  3. Pull through the relevant wiring, allowing plenty of spare.
  4. Wire in the Electric Relay as per the wiring diagrams provided, checking this is suitable as per the relevant installation manuals.
  5. Fit the Electric Relay into the pattress, ensuring there are no trapped wires, fit the blanking plate to the front of the pattress. Screw in using standard pattress screws, and check the unit is securely and safely attached to the wall.

Single Channel Receiver (Low Voltage/Volt free connections)

Image Removed

If you are controlling an underfloor heating wiring centre or actuators which are volt free or low voltage (such as 12v/24v) the Single Channel Receiver will be used per zone controlled. If there is an existing thermostat controlling the zone of underfloor heating it may be possible to swap the thermostat for the Single Channel Receiver as it uses a standard backplate. You need to ensure that wiring is correct for the Single Channel Receiver before placing it on the backplate.  

  1. Always ensure that the boiler, underfloor heating and wiring for the Single channel Receiver is electrically isolated before you commence work on any wiring.
  2. Remove the backplate from the Single Channel Receiver by loosening the 2 screws found on the bottom of the Receiver Unit.
  3. Mount the backplate onto the wall where the Single Channel Receiver is to be placed, or (if using an existing comaptible backplate) remove the front of the existing thermostat/receiver unit. This must be on a flat surface to ensure good contact between the Single Channel Receiver and backplate.
  4. Wire the Single Channel Receiver backplate as per the wiring diagrams provided, checking this is suitable as per the wiring centre installation manual.
  5. Fit the Single Channel Receiver onto the backplate by first fitting it to the top of the backplate and hinging the receiver unit down. This should hinge easily and should rest squarely on the backplate. If it does not attach easily first time, take the receiver unit off and try again.

  6. Tighten the screws underneath the Single Channel Receiver, and check the unit is securely and safely attached to the wall.
