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.
