Thermogroup 9.2mG Programmable Thermostat User Guide

Thermogroup 9.2mG Programmable Thermostat 

Compatibility

Thermotouch Manual Glass is compatible with Thermogroup NTC 10K floor sensor probes. NTC 10kΩ @ 25°C If your existing floor probe is from another thermostat manufacturer and is not compatible, set your
thermostat to ambient temperature sensing mode. (Not advisable for timber or other temperature-sensitive floors).

Replacing an existing thermostat?
Contact the manufacturer’s technical department and ask for the rating of the floor sensor at 25°C.

What’s in the box?

Check you’ve got everything:

• manual thermostat (5215 or 5216)
• Floor sensor probe (3m)
• Floor sensor conduit (2m)
• Fixing screws
• Installation guide

You will also need:

•  Electrical screwdriver
•  Deep electrical back box
•  Electrical test meter

Before you start
Your thermostat should be:

• Installed 1.2 – 1.5m from the floor
• On an interior wall
• Outside any wet zones (IP30)
• Installed on an RCD-protected circuit
• Away from drafts or heat influences
• Installed so that the floor sensor probe can be laid in a heated area of the floor
• Installed by a professional, in line with current IEE 17th Edition Part P regulations and local standards

Installing your thermostat

Switch off mains power
You will be installing your thermostat as part of a high-voltage mains electrical circuit. To ensure your safety and protect the thermostat, switch off the main power and remove the fuse from the spur before you start the installation.

CAUTION High Voltage Cables

Installation location
At this stage, it is likely that an RCD-protected electric underfloor heating system has been installed and a back box is already in place. The underfloor heating cold tail should be pulled up through the back box, and the sensor probe installed (in the conduit provided) within the wall cavity or pre-chased channel in a solid wall.

Maximum distances
Your thermostat can be installed up to 50m away from the underfloor heating system it is controlling, provided that the floor sensor is used to control the temperature. Underfloor heating cold tails and floor sensor probes can be extended up to 50m. Connect multiple heaters to the thermostat in parallel.

Release mounting plate

Use a flat screwdriver to press in the catch (1) and push the fascia down as shown (2) to release the clips holding the back plate and the thermostat fascia together. Disconnect the white ribbon cable.

Wiring diagram

Connect the Thermostat to the underfloor heating (UFH) cold tail, power supply, and floor temperature sensor. The floor temperature sensor is not polarity sensitive.

Fix mounting plate in position

Use a cross-head screwdriver to fix the mounting plate to the back box in the wall. Now you can connect the white ribbon cable to the fascia.

Fix thermostat fascia in place

Locate the thermostat onto the mounting plate and push it down to clip in place.

Switching on your system
It is important that all adhesives and grouting is dry and fully cured before you switch on your underfloor heating. Most adhesives take between 7 to 10 days to cure. Follow manufacturer guidelines. The temperature of your underfloor heating should be increased gradually to avoid thermal shock on the floor. Start at 15°C and work up to your desired temperature of 2-3°C per day. Observe any maximum temperature guidelines from your floor manufacturer.

Advanced Settings

Adjusting the settings
To access the settings, switch the unit off by pressing it.
Press and hold together for 7 seconds. Press to cycle between settings 01 to 12. Use and adjust the settings.
When you are finished, leave the thermostat idle for 30 seconds. It will automatically save your settings and switch them off.
Switch the unit on by pressing to continue using the thermostat with your new settings.
