Switch-on time
When anti-sticking protection is enabled, the length of pump running for the cyclical
protection function must be preset here. The actuator then switches the pump on for
the time set here without interruption, assuming that anti-sticking protection must be
executed.
Delay times
Switch-on delay (pump requirement)
The actuator only outputs the ON telegram to the pump after determination when the
delay time defined here has elapsed. The pump is not switched on when the actu-
ator determines within the time preset here that the pump must remain switched off,
due to a limiting value plus hysteresis again being undershot. This parameter is vis-
ible only if the pump control is enabled.
Definition of the minutes and seconds of the delay time.
Switch-off delay (no pump requirement)
The actuator only outputs the OFF telegram to the pump after determination when
the delay time defined here has elapsed. The pump is not switched on when the ac-
tuator determines within the time preset here that the pump must remain switched
off, due to a limiting value again being exceeded. This parameter is visible only if the
pump control is enabled.
Definition of the hours, minutes and seconds of the delay time.
Object polarity
This parameter defines the telegram polarity of the "Pump control" object. It is visible
only if the pump control is enabled.
Detect external pump control via object
The actuator is able to evaluate an external pump control signal (e.g. from another
heating actuator). The local heating actuator links the external telegram with the in-
ternal status of the pump logically as OR and outputs the result of this link via the
object "Switch pump".
This parameter will enable the object "External pump control" in the "Yes" setting. It
is visible only if the pump control is enabled.
