Example: Differential Temperature Control
Temperature sensor T2:
Yes
Differential T-PRO:
4K
Hysteresis T-PRO:
2K
Temperature T1 min:
50 °C
Temperature T1 max:
90 °C
Temperature T2 min:
50 °C
Temperature T2 max:
90 °C
Timer T-PRO:
On
T-PRO On 1:
08:00 hr
T-PRO Off 1:
16:00 hr
If the temperature at T1 is higher than T2 by 4k, the contact will close. If the
temperature of T1 falls back to within 2K of T2 the contact opens. If the
temperature exceeds the max temperature the contact opens and if it falls
below the minimum value the contact closes. This feature is only active
between 08:00 and 16:00.
Example: Temperature Switch
Temperature Sensor T2:
Nein
Temperature T1 min:
55 °C
Temperature T1 max:
60 °C
Overrun T-PRO
2 Minuten
If the temperature at temperature sensor T1 is lower than the preset
temperature of 55°C, the contact will close. When the temperature rises to
60°C, at sensor T1, the contact will open after the set overrun time of 2
minutes.

Holiday function
Holiday:
0 … 100 Day(s)
Holiday Operation: For the number of days set the heating circuit pumps,
boiler and DHW back-up heating is switched off. The frost protection function
remains active.
The holiday function can be found in the mainmenu options.
At low ambient temperatures, the home could become cold, therefore ensure
the holiday mode is turned off. In winter, if necessary, the minimum heating
flow temperature can be raised.
If the number of days is set to 0, all the systems that were switched off are
activated again. The flashing message ‘Active Holiday Function’ indictes the
holiday function is active.
