heating
T-Outside lim day Only if parameter [Pump Mode] = 1:
Setting the automatic summer shutdown of the heating system. If the outside tempera-
ture measured and averaged out by the controller exceeds the set value by 1 K, the heat-
ing circuit is switched off. The heating is relea
sed again if the outdoor temperature falls
below the set heat curve.
E E Off, 10 - 40 °C 19 °C 0.5 K
T-Outside lim night Only if parameter [Pump Mode] = 1:
Parameter for setting the heating limit for "Switch-off" of the heating circuit during setback
t
ime (functionality as for parameter [T-Outside lim day]).
E E Off, 10 - 40 °C 10 °C 0.5 K
Heat-Slope Only if parameter [HC Function] = 0:
Setting the heating curve. The heating curve ref
lects the dependence of the set inflow
temperature of the heating circuit on the outside temperature (see chapter 3.6.2).
E E 0.0 - 3.0 0.7 0.1
Room Influence Only if the room temperature controller
is connected and assigned to the heating 
circuit:
Setting of the impact the deviation of the room temperature measured by the RoCon U1
f
rom the actual set value (see chapters 3.4.3 and 3.4.4) has on the flow temperature.
Off : Purely weather-controlled flow temperature regulation, but internal heat recircula-
tion pump continues to run until the next heating cycle following a heat demand during
t
he setback time.
1-20: Causes a correction of the set flow temperat
ure (parallel shift of the heat curve) by
the set factor. If the measured temperature is 2 K below the set value, the set flow 
temperature is raised 2-times the set value.
E E Off, 1 - 20 K Off 1 K
T-Room Adj Only if the room temperature controller
is connected and assigned to the heating 
circuit:
Individual adaptation of the room temperature relevant for control.
Should a systematic deviation of the room temperature, measured by the RoCon U1,
f
rom the actual temperature in the living area of this room be detected, the measured 
value can be corrected by the set value.
E E -5 - 5 K 0.0 K 1 K
Heat Up Opt Heating up optimisation is a function for automatic
bringing forward of the start of heating.
Off : Deactivated
1: Weather-controlled bringing forward
2: Room-temperature-controlled bringing forward (only if the room temperature controller
is connected and assigned to the heating circuit.)
E E Off, 1, 2 Off 1
Max Operation Time When heating-up optimisation is activated the start of heating is brought forward by a
maximum of
the time set for this parameter (format hh:mm).
E E 00:15 - 03:00 02:00 15 min
Opt Reduced Function for preventing the HPSU compact starting up shortly before the end of the 
parameterised heating time (format hh:mm).
E E 00:00 - 02 :00 00:00 15 min
T-Flow Day Only if parameter [HC Function] = 1
Setting the inflow target temperature for the heating circuit during the heating time when
in ope
rating mode: "Automatic 1", "Automatic 2", "heating". "Cooling"
E E 20 - 110°C 40 °C 1 °C
T-Flow Night Only if parameter [HC Function] = 1
Setting the inflow target temperature for the heating circuit during the setback time when
in ope
rating mode: "Automatic 1", "Automatic 2", "Reducing".
E E 10 - 110°C 10 °C 1 °C
Cooling
Start T-Out Cooling This parameter is used to determine from which outdoor temperature the cooling mode
sta
rts (Setting condition: Operating mode cooling).
E E 20 - 45°C 24 °C 1 K
Max T-Out Cooling This parameter is used to determine from which outdoor temperature the lowest cooling
f
low temperature [T-Flow cooling start] or the highest set room value 
[T-Room max cooling] is stipulated (Setting condition: Operating mode cooling).
E E 20 - 45°C 35 °C 1 K
T-Flow cooling start This parameter is used to determine which flow temp
erature is stipulated at the start of
the cooling (outside temperature = parameter [Start T-Out Cooling]) 
(Setting condition: Parameter [Cooling] = ON).
E E 5 - 25°C 18 °C 1 K
T-Flow cooling max This parameter is used to determine which f
low temperature is stipulated at maximum
cooling (outside temperature = parameter [T-Flow cooling max]) 
(Setting condition: Operating mode cooling).
E E 5 - 25°C 8 °C 1 K
T-Flow Cooling Value of set flow temperature in cooling mode when regulating according to a fixed flow
t
emperature.
E E 8 - 30°C 18 °C 1 K
T-Room start cool-
ing
This parameter is used to determine to which set room temperature the cooling regulates
at
outdoor temperature = [Start T-Out Cooling].
E E 15 - 40°C 24 °C 0.5 K
T-Room max cool-
ing
This parameter is used to determine to which set room temperature the cooling regulates
at
outdoor temperature = Parameter [Max T-Out Cooling].
E E 15 - 40°C 28 °C 0.5 K
Cooling Setpoint Adj This parameter can be used for a parallel displacement of the set cooling characteristic
line (Condition: Operating mode cooling).
