10.3.2  Circulation

Switches a circulation pump on and off on a temperature and/or time 

controlled basis. 

Temperature control: If the temperature in the circulation return falls 

below the T

on

 value, then the circulation pump is switched on until the 

T

off

 temperature is reached.

Time control: The circulation pump is switched on when the current 

time lies within one of 3 configurable time windows.

Temperature and time control: The circulation pump is switched on when 

the switch-on conditions for the temperature and time control are satisfied.

 

Note

Install the circulation sensor at least 1.5 m (60 inch) away from the storage 

tank to avoid false measurements due to heat conduction of the pipes.
