MODE SELECTION
- Press any
key to wake-up the thermostat and activates the back- light. - Hold
key for 2 second to access to menu for selection of mode. - Press
permits to change navigate in different mode.
If “basic navigation” is activated (menu #03), navigation menu will be:
Change temperature setting
- Wake-up the thermostat by pressing any key.
- Press , to change the temperature set point (digits starts to blink).
- By pressing key, temperature set point value is validated.
Boost/Timer mode
- In mode boost, set point temperature is applied during a selected time.
- After this time, thermostat will return to former mode.
- You can first adjust, the desired setting temperature with, press key, to validate, default value 24°C.
- In a second time, you can adjust the duration in hours “H” if below 24H, then in day “d”.
AUTO mode
- This mode is activated only when thermostat is paired with a WATTS Vision® touch screen BT-CT02.
- In Auto mode, the heating system will follow program according to the current time and the Comfort and Reduced setting temperatures. By pressing keys,
- Boost/timer mode is selected, it override the temperature set point (1h).
Comfort mode
In this mode, comfort temperature set point will be followed all the time.
Reduced / ECO mode
This mode is activated only when thermostat is paired with a WATTS Vision® touch screen BT-CT02.
In this mode, reduced temperature set point will be followed all the time.
Note: In cooling mode, reduced mode acts like the OFF mode (system is stopped, NC actuators close).
Anti-freeze mode
Use this mode if you want to protect your installation against freezing. (default value 7°C).
Remark: in cooling mode, Anti-freeze mode acts like the OFF mode (installation is stopped).
OFF mode
Use this mode if you need to switch off your installation.
Be Careful: In this mode your installation can freeze.

TROUBLESHOOTING & SOLUTION
Description of thermostat errors displaying
Remote errors are:
- Error of temperature measurement
- Internal sensor;
- External sensor.
- Low batteries
- Loss of RF communication (only when remote is associated to Touch E3 or to master product).
| My Thermostat seems work correctly but the heating or the cooling doesn’t work correctly | |
| Output | On the receiver:
– Check the good reception of RF signal. – Check the connections. – Check the power supply of the heating element. – Contact your installer. |
| RF communication | Check the following points:
– The receiver must be put at a minimum distance of 50 cm of all others electrical or wireless materials (GSM, Wi-Fi..) – The receiver shouldn’t be fixed on a metallic part or too close of hydraulic pipes… (Copper…) |
| Sensor calibration | – Try to calibrate your thermostat (refer to user parameter 05).
– Contact your installer, to check & adjust the regulation parameters with your heating system. |
| Configuration | The logo blinks:
– Cooling request is made by the central (BT-CT02) but the thermostat doesn’t allow (refer to user parameter 08). |
MAINTENANCE
Battery level indication
The batteries are considered weak when voltage level is too low for a correct product functionning.
The icon will blinked
on LCD screen.
Cleaning of the thermostat
Gently dust the outside of the thermostat with a soft, lint-free cloth. If the thermostat needs a more thorough cleaning:
- Lightly dampen a soft and clean cloth with water.
- Wring out any excess water from the cloth.
- Gently wipe the display and sides of the thermostat, making sure no drops of water accumulate around the product.
