TDS75 Underfloor Thermostat is applied in Electrical or Water or Gas Boiler Underfloor Heating System. TDS75-WP series thermostats are used to control 3A Water Floor Heating Elements.


Underlfloor heating is to use electricity or water to achieve room underfloor central heating, is a kind heating way of transferring energy into heat energy to directly release heat to meet the central heating demand.  Thermostat is the switch to realize intelligent temperature control. It can freely adjust the indoor temperature, and can be set on or off according to user requirements for a variety of time and a variety of preset mode of automatic operation to adjust the room temperature, so that it reaches a comfortable temperature.

Product Functions            


main05-EN

     

Big LCD Screen


TDS75 thermostat features a large, easy-to-read screen showing current and set temperatures. You can easily adjust the settings using its simple touch button.

12-EN

         

Temperature Hysteresis


This refers to the temperature value of the thermostat turning on and stopping heating. For example, the current setting temperature is 25 ℃, and the starting temperature difference is set to 0.5 ℃. Then, when the room temperature is below 24.5 ℃, the heating is turned on, and the heating is stopped when it reaches 25.5 ℃.

When installing the thermostat, please note:


When installing the TDS75-WP thermostat for water floor heating systems, first ensure the power supply matches the thermostat's specifications and turn off the power before wiring.


Correctly connect live and neutral wires as per the diagrams, distinguishing between NC actuators and different 3 - wire valves. Ensure all connections are tight to avoid poor contact.


Also, properly install associated components like actuators and valves, and check that the external sensor (if applicable) is placed correctly for accurate temperature detection. Keep the thermostat away from water to prevent electrical issues.

FAQS            


1. Q: Can I install this thermostat by myself? Do I need to hire an electrician?

   A: Regarding the installation of the thermostat, we first recommend that you operate in strict accordance with the steps in the product manual under the guidance of professionals to ensure standardized installation and stable subsequent operation of the device. If you choose to install it yourself, you must carefully read the manual in advance, fully master the installation process, wiring requirements and safety precautions before starting the operation, so as to avoid affecting the device's function or causing potential safety hazards due to improper operation.


2. Q: Why is my water floor heating not reaching the set temperature?

    A: There could be several reasons. First, check if the thermostat is set correctly. Also, verify that the valves and actuators are functioning properly, and there are no blockages in the water pipes. The water temperature from the boiler might also be too low.


3. Q:  What should I do if the thermostat makes a clicking sound when adjusting the temperature?

    A: A normal clicking sound is typically caused by the thermostat’s internal relay switching on/off to control the connected valves or actuators—this is a sign that the thermostat is working properly. However, if the clicking is frequent or accompanied by temperature fluctuations, it may indicate a faulty relay or unstable room temperature. Check the sensor placement first; if the issue persists, contact technical support.


4. Q: How long is the product warranty period?

    A: Our products come with a 2-year free warranty. If there is a quality issue (such as failure to turn on or unresponsive buttons) after you receive the goods, you can contact the after-sales customer service and provide the order number and photos of the problem. We will arrange for a replacement or repair.
