Valve position cooling mode / summer operation

Specifies the position to which the valve of a room is driven (0..100%) when
the plant is switched to cooling mode or summer operation. The amount of
cooling energy drawn by the individual rooms can thus be influenced.
Rooms with high humidity levels also have a risk of condensation.

The setting has the following effect depending on the actuator type
used:
RRV912: 3-position actuator
The actuator exactly arrives at the set position.
RRV918 / RRV912: 2-point actuator (NC/NO)
The actuator is not controlled with setting 0..49% and remains in the
start position (for NC = 0%).
The actuator is controlled by a permanent pulse with setting 50..100%
and thus remains in the end position (for NC = 100%).
SSA955
The actuator exactly arrives at the set position.

Minimum valve position Comfort

To prevent cold floors in the case of floor heating systems, a minimum valve
position (0..100%) can be specified which is observed during Comfort periods,
even if the room temperature is sufficiently high. It is accepted that in such
cases the room may be overheated.

H/C changeover locking time

Changeover locking time prevents heating mode from changing to cooling
mode (and vice versa) too quickly and too frequently.
This means that when changing over, heating or cooling mode is disabled.
They are enabled again only when the changeover locking time has elapsed.
