Question 2

Why does the temperature remain lower than the set temperature on my EQUATION TH50DP6RF thermostat despite the heating demand?

Accepted Answer

If the temperature measured by your EQUATION TH50DP6RF thermostat remains lower than the temperature you have programmed, several causes may explain this phenomenon:

1. Check the thermostat settings

Make sure the desired temperature is set correctly and that the heating mode is activated.
Check that the thermostat is not in frost protection mode or eco mode, which limits the temperature.

2. Position and condition of the temperature sensor

The built-in temperature sensor may be poorly placed (near a cold or hot source), which skews the measurement.
A faulty sensor can also lead to incorrect readings of the ambient temperature.

3. Operation of the heating system

Check that your boiler or heating system is turned on and functioning properly.
Ensure that the radiators or heat emitters are open and not experiencing any issues (bleeding, blockage).

4. Air circulation and insulation

Poor air circulation around the thermostat or radiators can prevent effective temperature rise.
Insufficient insulation of the room or dwelling can lead to significant heat loss, making it difficult to reach the desired temperature.

In summary, check the settings and operation of the thermostat, the proper functioning of the heating system, the position of the thermostat, and the quality of the insulation. These steps generally help identify the cause of an ambient temperature that remains below the set point.

Question 3

Can the EQUATION TH40DP6 thermostat communicate with an external receiver?

Accepted Answer

The EQUATION TH40DP6 thermostat is not equipped with wireless communication. It is a programmable wired thermostat designed to connect directly to a boiler via two connection terminals: T1 and T2. These terminals do not require any separate external receiver, as they simply send a switching signal (on or off) directly to the boiler.

Connection to the boiler inputs: This thermostat must be connected to the inputs intended for a remote "ON/OFF" thermostat of your boiler. The signal sent by the TH40DP6 through the T1 and T2 terminals indicates to the boiler to start or stop heating according to the detected ambient temperature. The polarity of these connections does not matter.

No wireless protocol: This model does not support wireless communication protocols such as ZigBee, Z-Wave, or other home automation standards. It is a classic and reliable solution based on simple electrical pulses between the thermostat and the boiler.

Installation: Installation must be carried out by a qualified person in accordance with national wiring standards. The thermostat should be installed on a wall, at a height between 1.2 m and 1.5 m, away from heat sources (radiators, fireplace, sun) and drafts (windows, doors).

In summary, the TH40DP6 communicates only with your boiler via its two wired connection terminals T1 and T2. No additional external receiver is required: the boiler itself performs this function by receiving signals from the thermostat.

Question 4

How to calibrate the temperature display on the EQUATION TH50DP6RF thermostat?

Accepted Answer

The EQUATION TH50DP6RF thermostat generally does not offer a user-accessible calibration function to adjust the temperature display. This means you cannot directly correct any difference between the displayed temperature and the actual ambient temperature through a manual adjustment.

However, here are a few points to consider:

Check the thermostat settings: Browse through the configuration menus to see if a temperature compensation or adjustment option is available.
Thermostat positioning: Ensure that the thermostat is installed in a location that is representative of the ambient temperature, away from heat or cold sources that could skew the measurement.
Professional replacement or recalibration: If the temperature measurement is incorrect and affects your comfort, it may be necessary to have the thermostat checked or replaced by a professional.

In summary, there is no standard user procedure to calibrate the temperature display on this model. The best approach is to ensure proper installation and, if necessary, contact a specialist for a more in-depth diagnosis.

Question 5

How do I calibrate the EQUATION TH20DM thermostat?

Accepted Answer

Calibrating the EQUATION TH20DM thermostat involves compensating for the difference between the actual temperature of your room and the one displayed on the thermostat's LCD screen. This operation is performed via the installer mode by adjusting the ED (Sensor Calibration) parameter, which ranges from -30 to +30 with a factory value of 0. If your thermostat consistently shows a temperature 2°C warmer than reality, you need to decrease the ED parameter by 2 to compensate.

Start by measuring the actual temperature of the room where the TH20DM is installed using a reliable thermometer placed in the center of the room, away from heat sources or drafts. Wait a few minutes for the measurement to stabilize, then compare this temperature with the one displayed on the thermostat by pressing the adjustment buttons (the side buttons) which will flash the set temperature.

To access the installer mode of the TH20DM, press and hold one of the adjustment buttons for about 2 to 3 seconds until the screen displays the parameters in installer mode. Then navigate through the parameters (GE, Cr, Pp, ED, etc.) to reach the ED parameter corresponding to the sensor calibration. The adjustment buttons allow you to scroll through the parameters and adjust the value: if the displayed temperature is too low, increase the ED value by pressing several times; if it is too high, decrease this value.

After adjusting the ED parameter to the correct value to compensate for the measured difference (for example, from 0 to -2 if the thermostat shows 2°C too much), validate your changes by exiting the installer mode by holding the button down again for 2 seconds. The TH20DM will then return to normal operating mode with the calibration applied.

Check the effectiveness of the calibration by observing the thermostat for a few days: it should now display a temperature consistent with your reference thermometer and correctly regulate your boiler to achieve the desired thermal comfort. If the discrepancy persists, repeat the procedure by further adjusting the ED parameter until the required accuracy is achieved.

Question 6

How to reset the EQUATION TH50DP6RF thermostat?

Accepted Answer

To reset your EQUATION TH50DP6RF thermostat, follow the steps below:

Turn off the thermostat: Press the power button to turn off the device.
Access the reset mode: Press and hold the temperature adjustment button (often marked "Set") while turning the thermostat back on.
Confirm the reset: A message or symbol should appear on the screen indicating that you are in reset mode. Follow the displayed instructions to confirm the operation.
Reprogram the thermostat: After the reset, you will need to reconfigure your temperature and schedule settings according to your preferences.

This procedure resets the thermostat to its factory settings, useful in case of malfunction or before a new configuration.

Question 7

How to activate automatic mode on the EQUATION TH50DP6RF thermostat so that heating starts without manual intervention?

Accepted Answer

To activate automatic mode on your EQUATION TH50DP6RF thermostat and allow heating to start without manual intervention, you must first switch to AUTO mode, then set the schedule. The thermostat has three buttons: the left button (MENU), the central button ([AUTO] MAN), and the right button for Frost Protection mode.

Step 1: Switch to AUTO mode

Press the central button [AUTO] MAN to switch from MANUAL mode to AUTO mode. The screen will then display the AUTO indication. If the screen shows OFF (Frost Protection mode), first press the right button to reactivate the thermostat, then use the central button to select AUTO.

Step 2: Access the programming

Once in AUTO mode, press the MENU button (left) to enter the programming menu. The symbol and the PROG indication will flash on the screen. The TH50DP6RF thermostat allows for 6 temperature changes per day, programmable between 0h and 23h50, with time slots and temperatures that you can customize for each day of the week.

Step 3: Set the time slots

For each programmed slot, set the start time and the desired setpoint temperature between 5°C and 35°C. Confirm your settings by pressing the right button (Q) after each entry. The default programs of the thermostat already offer operating ranges that you can modify according to your heating needs.

Step 4: Operation of AUTO mode

Once programming is complete, heating starts automatically according to the slots you have defined. The thermostat compares the ambient temperature to the programmed setpoint temperature and activates the boiler when necessary. You can also temporarily adjust the setpoint temperature with the adjustment buttons (A and V) in AUTO mode, but this adjustment will be canceled at the next programmed time slot.

If you do not wish to program the time slots yourself, the thermostat has default programs in AUTO mode that will allow heating to start automatically according to a standard schedule.

Question 8

How to reset the programmer of the EQUATION TH40DP6 thermostat?

Accepted Answer

To reset the programmer of your EQUATION TH40DP6 thermostat, you need to access the installer mode where two reset options are available: resetting only the programs (SSD) or a complete reset to factory values (GFS).

Accessing installer mode:

Press and hold the MENU (left button) and A (temperature setting) buttons simultaneously for 3 seconds.
The thermostat will switch to installer mode.

Resetting only the programs (SSD):

Once in installer mode, use the A and Y buttons to navigate to the SSD (Reset Programs) setting.
Press the OK button to select this setting.
Set the value to 1 (Reset) using the A and Y buttons.
Press OK again to confirm and reset your custom programs.

Important: Resetting the programs (SSD) only clears your custom settings while a complete reset (GFS) restores the entire thermostat to its factory output configuration, including all technical settings. Your programming memory is retained when replacing batteries, so an SSD reset will be necessary if you have lost programs due to another cause.

Question 9

Why doesn't the small flame appear on the EQUATION TH50DP6RF thermostat?

Accepted Answer

The small flame on your EQUATION TH50DP6RF thermostat only appears when the thermostat is actively requesting the boiler to start. Its absence does not necessarily indicate a problem, but rather that no heating is currently being requested.

Main reasons for the absence of the flame:

Temperature reached: If the ambient temperature in your room has already reached or exceeded the temperature you set on the thermostat, it will not command the heating to operate. The flame will only appear when the temperature drops below your set point.
Frost protection mode activated: If the frost protection mode (which automatically triggers at +5°C) is active, the thermostat may be in protection mode and not requesting regular heating.
Thermostat off or in OFF mode: Check that the thermostat is not turned off and that the programming has not stopped heating for the current period.
Power supply issue: The TH50DP6RF can operate on batteries or mains power depending on your installation. If the batteries are low, check the battery symbol on the backlit digital display. Replace the batteries or check the electrical connection if the model is wired.
Loss of wireless connection: This thermostat communicates via radio frequency (RF) with its receiver connected to the boiler. If this connection is lost, the boiler does not receive the heating request. Check that the radio signal symbol is displayed on the screen and ensure that the receiver is on and properly connected.
Boiler malfunction: If the boiler itself has a fault, an error code, or is not powered, it will not be able to respond to the thermostat's request even if it commands it.

Troubleshooting steps: First, intentionally lower the set temperature to create a heating demand - if the flame appears, it means a setting is blocking the heating. Check the screen display to identify active symbols (low battery, frost mode, connection issue). Consult the LED indicator and manual button on the receiver to ensure it is paired and powered. If the flame still does not appear after these checks, or if other error symbols are displayed, contact a qualified installer to diagnose a possible boiler or thermostat configuration issue.
