TROUBLESHOOTING & SOLUTION

Description of thermostat errors displaying
Remote errors are:

•  Error of temperature measurement
  o Internal sensor;
  o 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 functioning.
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.
  Important: Do not spray thermostat direct-ly with water, or use cleaning solutions or polishes, as doing so may damage the thermostat.
