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.

Standard wiring diagrams are provided with the system. To download a copy of the wiring diagrams, visit: https://www.geniushub.co.uk/wiring All devices which control the heating in individual rooms and are purchased as part of a system direct from Genius Hub, such as Underfloor Receiver Units, Genius Radiator Valves or Room Sensors, are labelled with the room they control and are pre-linked to zones on the app. |
Powered Room Thermostat (Switched Live connections, or Single Zone / Underfloor Pump, Electric Underfloor)
If you are controlling an underfloor heating wiring centre or actuators which are 230v the Electric Switch Powered Room Thermostat will be used per zone controlled. If there are any existing controls, such as a thermostat the wiring to these will need to be removed. The Electric Switch is often wired wired into the room being controlled so it can detect the temperature, not near the actuators / wiring centre and the Room Sensor or Room Thermostat placed in the room with the underfloor heating.
If you are only controlling a single zone of underfloor heating, you are likely to need to switch the underfloor circulation pump directly from the controller Powered Room Thermostat along with any zone valves or actuators. The Electric Switch is to can also be used in these situations.
- The Powered Room Thermostat fits into a standard 1-gang pattress, we recommend approximately 40mm deep.
- If you are using a flush mount pattress it should screw in without any problems.
- 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.
- Wire in the temperature probe or link into the 'Floor Sensor' terminals.
- Install the pattress into the room the Powered Room Thermostat is going to control.
- If using the floor probe, consider how this is going to get out of the pattress and it is going to be installed into the floor layer/onto the pipework of the wet underfloor.
- Wire in the mains power and the heating load to the Powered Room Thermostat.
- 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.
- 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.
- See 1.b if using a surface mount pattress.
- See 1.b if using a surface mount pattress.
- Place the frame on the Powered Room Thermostat and push the screen in place to secure the two parts to the main unit.
- If using the Floor Prove, fit this into the floor layer before powering using 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)
If you are controlling an underfloor heating wiring centre or actuators which are 230v the Electric Switch will be used per zone controlled. If there are any existing controls, such as a thermostat the wiring to these will need to be removed. The Electric Switch is often wired near the actuators / wiring centre and the Room Sensor or Room Thermostat placed in the room with the underfloor heating.
If you are only controlling a single zone of underfloor heating, you are likely to need to switch the underfloor circulation pump directly from the controller along with any zone valves or actuators. The Electric Switch is to The Powered Room Thermostat be used in these situations.
...
In normal operation there will be no lights when the unit is off and one or more red lights near the button when heating.
Electric Relay (Low Voltage/Volt free connections or Switched Live connections)
The Electric Relay can control an underfloor heating wiring centre or actuators which are 12v/24v/230v and will be used per zone controlled. If there are any existing controls, such as a thermostat the wiring to these will need to be removed. The Electric Relay is often wired near the actuators / wiring centre and the Room Sensor or Room Thermostat placed in the room with the underfloor heating.
- Always ensure that the boiler, underfloor heating and wiring for the Electric Relay is electrically isolated before you commence work on any wiring.
- 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.
- Pull through the relevant wiring, allowing plenty of spare.
- Wire in the Electric Relay as per the wiring diagrams provided, checking this is suitable as per the relevant installation manuals.
- 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)
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.
...
In normal operation the Single Channel Receiver will have a single solid light (red for when there is no call for heat, and green for when the Receiver unit is is calling for heat).
General Information
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 a circulation pump 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.
