3.6.3 Cooling characteristic curve

Caution - risk of condensation in the screed!
In the event of a fault or wrong setting of parameters,
damage may be caused to the screed, the structure of
the floor and the underfloor heating system by conden-
sation.
● Before initial commissioning, set the maximum
permissible system temperature in the minimum
temperature limit in the Control RoCon HP
(parameter [Min T-Flow Cooling]).
With the cooling characteristic curve, the flow temperature is 
adjusted to building conditions in accordance with the relevant
outdoor temperature (see section 3.6.2). Warmer outdoor tem-
peratures result in a cold flow temperature and vice versa.
The cooling characteristic curve is adjusted using the following
four parameters:
– [Start T-Out Cooling]
– [Max T-Out Cooling]
– [T-Flow cooling start]
– [T-Flow cooling max]
During the weather-controlled flow temperature regulation, the
user can adjust the flow temperature using the parameter
[Cooling Setpoint Adj] by a maximum of 5 °C up or down. The
lower temperature limit is limited by the parameter [Min T-Flow
Cooling].
