Actuator running time
This defines the running time of the actuator used. This is the time
the actuator requires to travel from one end position to the other.
The setting only acts on 3-position actuators. It has no impact
on 2-position actuators and SSA955 radiator control actuators.
The actuator running time (1..600 s) can be set separately for every
zone valve. For your guidance, refer to the standard settings:
Room type Guide value switching differential
Radiator heating slow 150 s
Radiator heating fast 150 s
