3.6.2 Heat slope
The heat slope is used to adjust the T-HS to the characteristics
of the building independent of the respective outside temperature
(weather-dependent T-HS control, see chap.
3.6.3). Generally
speaking, the steepness of the heating slope describes the ratio
of the T-HS change to the external temperature change.
The heat slope is valid within the limits of the minimum and
maximum temperatures set for the respective heating circuit. The
room temperature measured in the occupied area may differ from
the desired room temperature; these deviations can be kept to a
minimum by installing a room thermostat or a room control.
The control unit is set at the factory in such a way that the heat
slope does not independently adjust itself during operation.
The automatic heat slope adjustment can be activated ([HC
Adaption] parameter) if the outside temperature sensor
(RoCon
OT1) and the room control (EHS157034) are con-
nected (see chap. 3.6.3).
Start conditions for automatic heat slope adjustment:
– Outside temperature < 8 °C
– Operating mode is automatic (I or II)
– Duration of the setback period is at least 6 h
If no automatic heat slope adjustment is activated, the heat
slope can be manually adjusted by adjusting the [Heat-Slope]
parameter).
Detailed explanations and possible setting values of this function can be found in
chap.
6.2.
Caution – Risk of overheating of
floor heating!
In the event of malfunction or during manual
operation, the floor heating, the screed or the
floor structure could be damaged due to over-
heating.
● Prior to initial commissioning, set the
maximum temperature limit in the RoCon BF
control unit ([Max T-Flow] parameter) to the
maximum permitted system temperature
prior to starting the emission measurement.
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.
