6.2.2 Setting the anti-cycle time
(Service Function 2.4)
This service function is only active if Service Function
2.7, automatic anti-cycle time, is deactivated.
The anti-cycle time can be set to between 0 and 15 min-
utes (is factory set to 3 minutes).
If the setting 0 is entered, the anti-cycle time is inactive.
The shortest possible anti-cycle time is 1 minute (rec-
ommended for single-pipe and hot-air heating systems).
If the appliance is connected to an out-
i
side-temperature controlled heating pro-
grammer, the anti-cycle time does not
need to be set on the appliance and is op-
timised by the programmer instead.
6.2.3 Setting the maximum flow temperature
(Service Function 2.5)
The maximum flow temperature can be set to between
35˚C and 88˚C (factory setting).
6.2.4 Setting the switching difference
(Service Function 2.6)
If the appliance is connected to an out-
i
side-temperature controlled programmer,
the programmer sets the switching differ-
ence.
It does not need to be set on the appli-
ance.
The switching difference is the permissible divergence
from the specified flow temperature. It can be set in
increments of 1 K. The adjustment range is 1 to 30 K (is
factory set to 0 K). The minimum flow temperature is
30˚C.

6.2.5 Setting the heating output
(Service Function 5.0)
The heating output can be set to any level between min.
rated heat output and max rated heat output to limit it to
the specific heat requirements.
The full rated heat output is still available
i
for hot water or charging the hot water cyl-
inder even if the heating output has been
limited.
The factory setting is the max. rated heat output.
B Set the room thermostat and thermostatic radiator
valves to max. temperature.
