True Comfort PS120WF Smart Floor Heating Thermostat Installation Guide

Warnings

The installation of this thermostat must be performed by a certified electrician and comply with the national and local electrical codes and regulations.

Before starting the installation of your new thermostat, make sure that the breakers for your heating system are off at the main electrical panel!

INSTALL YOUR THERMOSTAT

1. Unlock and lift the thermostat cover.
   

2. Connect the heating floor by using the load / line wire connectors located on the back of the thermostat.
   Connect the ground wire to the screw in the electrical box intended for this purpose.
   Make sure to firmly tighten the wire connectors for a secure connection. A loose connection can be a fire hasard.
   

3. Connect the sensor.
   (Only for control applications in F mode or with floor limit.)

4. Use the screws to secure the thermostat to the electrical box. Replace the cover and lock.

5. Power up the thermostat.
   After performing a test sequence, the thermostat should display the floor temperature. If not, refer to the troubleshooting guide in this manual.

Increasing or lowering the temperature
To adjust the temperature, press or . The requested temperature will blink to confirm the new setpoint.

Leaving the standby mode
When the thermostat has been put in standby mode from the True Comfort app, press twice on or to turn back ON the thermostat. The thermostat will resume operation under its last program settings.

A thermostat that is placed on standby before a power failure will be on standby by default when power is restored.

USER SETTINGS

All of the thermostat’s settings can be set through the True Comfort app.

However, if you have not created your account and wish to change the temperature format or the control cycle, you need to:

Get the setpoint to its minimum and hold the button for 10 seconds to access the menu.

Press the or button to change the setting.

Press the and buttons simultaneously to save and go to the next parameter. Continue to press until the end of the list to exit the menu.

The following table lists the settings that can be changed directly on the thermostat. You can change more settings through the True Comfort application.

Settings which can be modified directly on the device:

1. Load Power
   Read-only information

2. Temperature format
   Allows you to choose the desired temperature format.

3. The thermostat offers 2 temperature regulation modes:
   F mode (default): Regulates the floor temperature by means of an external temperature sensor with the possibility to limit ambient temperature.
   A mode: Regulates ambient temperature with the possibility to limit floor temperature by means of an external temperature sensor

4. Maximum limit of the ambient temperature (F mode)
   Thermostat limits floor heating so as not to exceed the set ambient temperature limit

5. Maximum floor temperature limit
   The thermostat limits floor heating to the set temperature to ensure it does not exceed the selected limit: ideal for protecting engineered wood floors.
   This parameter can only be used when a floor sensor is connected to the thermostat.

6. Minimum floor temperature limit (A mode)
   The thermostat limits the minimum temperature of the floor in order to keep it at a comfortable temperature.
   This parameter can only be used when a floor sensor is connected to the thermostat.

7. Assigning the auxiliary output:
   The thermostat provides an auxiliary output that has three functions which are set from the user settings.

15 sec function: Short cycle auxiliary output (15 seconds): used for a heater controlled through an electronic relay (SSR).

15 min function: Long cycle auxiliary output (15 minutes): used for a heater controlled through an electromechanical relay or equipped with a fan.

In the 15 sec and 15 min functions, the thermostat controls the ambient temperature with the floor. Once the floor temperature has reached its limit, if the desired ambient temperature is not reached, the auxiliary output activates the heating device to reach the set temperature. (The auxiliary output acts as a second heating stage.)

EXP function: Auxiliary output to connect several heating floors (expansion unit sold separately)

OFF function (default): Disables the auxiliary output

When installing your floor heating system: add a second sensor in the floor and store the connection cable in the thermostat’s housing. This additional sensor can be plugged in and used as a replacement without altering your floor heating system.

CONNECT THE AUXILIARY OUTPUT

Second heating stage (15 sec / 15 min functions)

ADD YOUR THERMOSTAT TO THE APP

1. Download the free True Comfort application on your mobile device from the App Store or Google Play *.

2. Open the application and sign into your True Comfort account or create an account.
3. In the menu on the right, choose “Add a device” and follow the steps on the screen.

DISCONNECT YOUR THERMOSTAT FROM THE WI-FI ROUTER OR THE APP

To disconnect your thermostat from the Wi-Fi router, press the and buttons simultaneously for 10 seconds. The symbol will disappear from the display.

To remove your thermostat from the True Comfort App, press Delete in the thermostat’s settings.

GROUND FAULT PROTECTION

The thermostat is equipped with a ground fault protection that can detect a current leakage of 5 mA. When a current leakage is detected, the ground fault protection is triggered and quickly interrupts the power supply to prevent any serious injuries.

Resetting the ground fault protection
The RESET button warning light turns ON (red) when the ground fault protection is triggered. If the RESET button warning light turns ON during normal operation of the thermostat, simply press the RESET button to reset the ground fault protection. The light will turn OFF. If for any reason this situation occurs again, cut the power to the heating system from the main electrical panel and ask a qualified electrician to verify the installation.

Testing the ground fault protection
This thermostat has an Auto Test which periodically verifies the correct operation of the protection circuit. You can also do this manually:

1. Press the TEST button. If the RESET button’s red warning light does not turn ON, the test has failed. Cut the power to the heating system from the main electrical panel and ask a qualified electrician to verify the installation.
2. Press the RESET button to restart the thermostat’s base.

TROUBLESHOOTING GUIDE

What should I do if the E1F code appears on my thermostat’s display?
The E1F code means that the thermostat is in “Floor” mode and there is no connected sensor. If your thermostat is not intended to control a heated floor, change the thermostat’s control mode for the “A mode”. If an error code is displayed, or for more information, contact STELPRO customer service at : 1 844-STELPRO.
