Room thermostat control - Using 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 radiators and heat pump
convectors and/or fan coil units. You only have to adjust
leaving water temperature settings in case of problems.
For more information about the leaving water temperature, see the
user reference guide.
