Troubleshooting & Solution

My BT D doesn’t start
Batteries Problem	– Check if the protection sticker on the batteries is removed. – Check the batteries orientation. – Check the capacity of the batteries
My BT D Led, blinks in Red
Problem on sensors	The logo blinks (ambient sensor) – Contact your installer or seller.  The logo blinks (Floor sensor) – Check the connection of the sensor. – Disconnect the sensor, and check it with an ohmmeter (the value must be around 10kohms)
Batteries level is too less	The logo blinks (Batteries) – Replace the batteries.
My BT D seems work correctly but the heating doesn’t work correctly
Output	– Check the connections. – Check the power supply of the heating element. – Contact your installer.
My BT D seems work correctly but the temperature in the room was never in accordance with the program.
Temperature	– Try to calibrate your thermostat (see user menu parameter 04) – Contact your installer, to check & adjust the regulation parameters with your heating system.
