active in Economy mode
and Protection mode

Whether the heating limit function shall be active in operating mode “Continuously
Comfort “ can be selected on the “Space heating“ menu.
This setting is always active, independent of whether the operating mode was switched
to “Continuously Comfort
“ or through the room operating mode contact.
Ex-
empted from this is the room control combination with an RMU7… ventilation controller;
here, the heating limit is always active.
For operation in combination with the ventilation controller, summer / winter operation
changeover is used as an overriding function.
When the attenuated outside temperature exceeds the Comfort heating limit, a change
to summer operation will take place; this also applies to operating mode “Continuously
Comfort “.

Mixing valve control
9.6.1 Control
The flow temperature setpoint determined by weather-compensated heating circuit
control generates the effectively active setpoint for mixing valve control while giving
consideration to load control.
Mixing valve control can be effected with a 3-position or DC 0…10 V actuator. The type
of actuator is to be selected via “Extra configuration“.
The following mixing valve settings apply to both the 3-position and the DC 0…10 V
actuator:
