Result: For the next 2 hours, the room will NOT be heated to the
scheduled 20°C, but to the preset value (Eco = 18°C). After the

INFORMATION
The leaving water is the water that is sent to the heat
emitters. The desired leaving water temperature is set by
your installer in accordance with the heat emitter type.
Example: Underfloor heating is designed for lower leaving
water temperature than
convectors and/or fan coil units. You only have to adjust
leaving water temperature settings in case of problems.
