Circulation function
A circulation pump can be controlled in a time-based, temperature-
based, or pulse-based manner. These types of control can also be com-
bined with each other.
Time control: time switch with 3 time windows.
Temperature control: when the temperature in the circulation return
falls below the "on" value, then the pump is switched on until the "off"
temperature is reached.
NOTE
In order to avoid measurement errors caused by the pipe's thermal con-
duction, a minimum clearance space of 1.50 m from the storage tank
should be observed when installing the circulation sensor.
Pulse control: when the circulation function is requested via a pulse
(e.g. from a flow switch), the pump runs for the set circulation duration.
Subsequently, no further requests are accepted until the set wait time
has expired.

will also be changed to a later time if necessary. Adjusting the switch-off
value to a time before the switch-on value is blocked.
