Menus

• ME.1: Limits the range of the desired room temperature.
• ME.2: Information / version number, can be used to identify the product.
• ME.3: Performs a connection test with the main controller. It returns a result in the form of a percentage (0-100%). 80% or higher indicates a very strong connection.
• ME.4: Floor sensor mode:
  • CO = Comfort mode. Both the room sensor and the floor sensor are used.
  • FL = Floor sensor mode. The end-user sets the desired floor temperature.
  • du = Dual mode. The thermostat controls radiators and underfloor heating circuits. The underfloor heating circuits ensure a minimum floor temperature, and the radiator is used for peak load.
• ME.5: Minimum and maximum floor temperatures used in CO and du modes.
• ME.6: Reference room. Enable this option (ON) if you want this thermostat to function as a reference for switching between cooling and heating.
• ME.7: Cooling ON/OFF. Used to disable the cooling option, for example, in bathrooms.
