Operation
Detailed explanations and possible setting values of this function can be found in
chap. 6.2.
3.6.3 Cooling slope
The cooling slope is used to adjust the target feed temperature to
the characteristics of the building depending on the respective
outside temperature (weather-dependent T-HS control, see
chap. 3.6.4). Warmer outside temperatures result in a colder
target feed temperature and vice versa.
Prerequisites for
cooling mode
:
– Outside temperature > set target room temperature value
– Outside temperature > set value of the parameter [Start T-Out
Cooling]
–
"Cooling"
operating mode activated.
a) Via rotary switch in
"Operating Mode"
position or
b) via room thermostat function (cooling
switching con-
tact closed)
– No heat request active in the heating system's RoCon sys-
tem.
Manually adjusting the heat slope
Do not make any corrections to the set values for 1 - 2
days, and then only make them in small increments.
●
Deactivate the external heat sources (e.g. stoves, direct
sunlight, open windows).
●
Fully open any radiator thermostat valves or actuators.
●
Activate "Heating" operating mode.
Approximate setting values:
– Radiators and system 70: 1.4 to 1.6.
– Floor heating: 0.5 to 0.9.

Caution - risk of condensation!
In the event of malfunction or incorrect parame-
ter settings, the floor heating, the screed or the
floor structure could be damaged due to con-
densation.
●
Prior to initial commissioning and activation
of cooling mode, set the minimum temper-
ature limit to the minimum permissible
system temperature in the RoCon mb
controller (parameter [Min T-Flow Cooling]).
