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.
General Information
| Info |
|---|
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. |

| Warning |
|---|
Do not attempt to wire in any devices 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 and underfloor heating for the new devices must be electrically isolated before you commence work on any wiring! |

Underfloor Wiring Centre
Depending on the control devices purchased, the Genius Hub system can be wired in a variety of ways, and to different voltage actuators and wiring centres. If you are using our Underfloor Wiring Centre, the terminals on the right-hand-side for the Manifold Pump and Underfloor Zone Valve are volt-free. See our wiring diagrams (link above) for how to connect to a 230v Pump/Zone Valve.
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 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 Powered Room Thermostat is wired into the room being controlled so it can detect the temperature, not near the actuators / wiring centre.

- 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 provided 10kΩ resistor provided into the 'Floor Sensor' terminals. (If using an existing probe, it must be 10kΩ at 25°C)
- 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 will 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, taking care to place the spacers between the device and the pattress.
- See 1.b if using a surface mount pattress, taking care to place the spacers between the device and the pattress.
- 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.
- 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)
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.

In normal operation there will be no lights when the unit is not heating 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.
