of start power
The start power parameter determines a percentage setting for
part of the modulation runtime during the start-up phase. With a
setting of 0% the actuator valve remains always closed. As soon
as the set start time has expired, the modulation switches to its
normal control characteristics defined by the modulation
parameters.
