A2
Switching differential
(hysteresis)
Setting range:
0.5 to 2.5 °C
Example: For a setting of
1 °C and the thermostat
temperature set to 20 °C,
the thermostat will switch
heating on at 19 °C and
off at 21 °C.

A3
High temperature
protection/difference
setting (external sensor)
Setting range: 1 to 9 °C
Example: The limit
value ‘A6’ is set to +45
°C and ‘A3’ to 2 °C. If
a temperature of +45
°C is reached, heating
mode is interrupted. If
the temperature drops to
+43 °C, heating mode is
resumed. This only works
if the indoor temperature
is lower than the target
temperature.
2 °C

Sensor selection
N1 = The internal sensor controls
the temperature.
N2 = The external sensor controls
the temperature.
N3 = The internal sensor controls
the temperature. If N3 is
activated, the external sensor
is used as the temperature
limiting sensor.
With all of the settings
above, if the maximum
temperature is reached,
heating mode is
interrupted.
