Pump kick is enabled.
Main Index > Configuration > Configuration 2 > Hrec (pump)/cmd = Yes+Kick
The pump is switched on for a short period for longer idle periods. This prevents
lock up.

5.7.4 Heat recovery Frost
Frost protection type is enabled:
Master Index > Configuration > Configuration 2, Heat recovery frost <> No
• Temperature frost protection: Detects icing using a temperature sensor in the
water exchanger if selected as water or in exhaust air if selected as plate or
wheel. This applies for the following settings:
Heat recovery frost = Detector, sensor or Dtctr+Snsr.
• Air-side frost protection: Detects icing using a pressure sensor. This applies
for the following settings:
Heat recovery frost = PressSnsr und Pres+Dtctr.
– For output Frost controller > Output recovery ---> The output follows the recov-
ery.
– For output Frost controller < Output recovery ---> The output follows the frost
controller.
– Controller is disabled when the sensor fails.
The heat recovery controller goes to 100 % output signal as soon as the frost con-
troller is no longer enabled, when the subsequent heating register was enabled
during frost control.

Weekday and time for pump kick. Sets the weekday
(Mon...Sun) and time to run the pump kick.
Examples:
Mon *:* Each Monday at midnight.
Sat 07:* Each Saturday at 7:00 am.
* *:* Time is not relevant; the kick interval applies
accordingly.
Idle time for pump kick. Set the idle time after which a
pump kick is run. Examples:
168 After 168 hours.
123.4 After 123 hours and 24 minutes.
0 Idle time is not relevant; kick date/time applies
accordingly.
Set the period for the pump kick.
Examples:
10 Period = 10 seconds.
0 Period = 1 controller cycle (ca. 150 ms).
