Room temperature probe regulation offset
Switching off for long periods
When switching off for a season or for holidays, proceed
as follows:
- Deactivate the device
- Turn the general unit switch to off.
The antifreeze function is not active.
As the detection probe is towards the bottom of the
device, the temperature detected may at times differ from
the actual room temperature.
By using this function, the value displayed can be adjusted
in a range from -9 to +12 K in intervals of 1°C.
Use this adjustment with care, and only after having
actually detected a discrepancy compared with the actual
room temperature using a reliable device!
