6.2 Adjustment channels
∆T control
DT O
Switch-on temperature difference
Adjustment range: 1.0 … 20.0 K [2.0 … 40.0 °Ra]
Factory setting: 6.0 K [12.0 °Ra]
The controller works as a standard differential controller. If the temperature reach-
es or exceeds the switch-on temperature difference, the pump switches on.
When the temperature difference reaches or falls below the adjusted switch-off
temperature difference, the respective relay switches off.
Note:
The switch-on temperature difference must be at least 0.5 K [1 °Ra] high-
er than the switch-off temperature difference.
DT F
Switch-off temperature difference
Adjustment range: 0.5 … 19.5 K [1.0 … 39.0 °Ra]
Factory setting: 4.0 K [8.0 °Ra]
Note:
If the drainback option ODB is activated, the values of the parameters
DT O, DT F and DT S will be adapted to values suiting drainback sys-
tems:
DT O = 10 K [20 °Ra]
DT F = 4 K [8 °Ra]
DT S = 15 K [30 °Ra]
Adjustments that have been previously made in these channels will be
overridden and have to be entered again if ODB is deactivated later on.
