Underfloor Heating Thermostat with Analogue Control
The TH131 underfloor heating thermostat provides simple and reliable temperature control for electric underfloor heating systems. Designed for users who prefer straightforward manual operation, it uses a clear analogue temperature dial without complicated programming or digital menus.
Suitable for residential and light commercial applications, the TH131 can control electric heating mats, heating cables and other compatible radiant heating systems.
Simple Analogue Temperature Control
The easy-to-use temperature dial allows the desired temperature to be adjusted quickly and precisely.
Its straightforward operation makes the TH131 a practical choice for homes, rental properties, offices and other locations where simple manual heating control is preferred.

Three Temperature Control Modes
The TH131 thermostat provides three selectable operating modes:
Air Temperature Mode
Controls the heating system according to the measured room temperature.
Floor Temperature Mode
Uses the external floor sensor to regulate the floor temperature directly.
Combined Air & Floor Limit Mode
Controls the room temperature while using the floor sensor to limit the maximum floor temperature.
The combined mode can be particularly useful with temperature-sensitive floor finishes where maximum floor temperatures need to be controlled.
Designed for Electric Underfloor Heating
The TH131 is suitable for compatible electric underfloor heating systems, including:
-
Electric heating mats
-
Electric heating cables
-
Radiant floor heating systems
-
Compatible residential heating installations
-
Light commercial heating installations
With a maximum switching capacity of 3450W at 230V / 15A, the thermostat can directly control compatible electric heating loads within its specified electrical limits.
Floor Temperature Sensor Included
The thermostat includes a 3 metre floor sensor cable for accurate floor temperature monitoring.
Using a floor sensor allows the thermostat to regulate or limit floor temperature according to the selected operating mode.
This is particularly important when using floor finishes such as compatible wood, laminate or vinyl that may have manufacturer-specified maximum temperature limits.
Clean and Discreet Design
Finished in polar white, the TH131 has a simple appearance designed to integrate with a wide range of interiors.
It is suitable for use in:
-
Living rooms
-
Bedrooms
-
Kitchens
-
Offices
-
Suitable bathroom installations
-
Commercial spaces
Installation
The TH131 is designed for permanent connection to a compatible electric heating system.
Electrical installation, connection and testing should be completed by a suitably qualified electrician in accordance with the manufacturer’s instructions and applicable electrical regulations.
The connected heating load must not exceed the thermostat’s maximum rating of 15A / 3450W at 230V.
Frequently Asked Questions
Is the TH131 suitable for electric underfloor heating?
Yes. The TH131 is designed to control compatible electric underfloor heating mats, heating cables and radiant floor heating systems.
Does the thermostat include a floor sensor?
Yes. A 3 metre floor temperature sensor cable is included.
What is the maximum heating load?
The maximum switching capacity is 3450W at 230V / 15A.
Can it control both room and floor temperature?
Yes. The thermostat provides air sensing, floor sensing and combined air temperature with floor limit control modes.
Is the TH131 programmable?
The TH131 is an analogue thermostat designed primarily for simple manual temperature control rather than advanced programmable or WiFi operation.
Can it be used with laminate or wood flooring?
It can control compatible underfloor heating installations beneath these floor finishes. The flooring manufacturer’s maximum temperature and underfloor heating requirements must always be followed.
