your installer in accordance with the heat emitter type.
Example: Under floor 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.

INFORMATION
It is recommended NOT to use the selection of ([6‑0D]=0,
[A.4.1] Domestic hot water Setpoint mode=Reheat only) in
case of a domestic hot water tank without internal booster

comfort problems is significant (in case of frequent
domestic hot water operation, frequent and long space
heating/cooling interruption will happen).
