T-Flow Day Only if parameter [HC Function] = 1
Setting the inflow target temperature for the heating circuit during the heating time when in

operating mode: [Automatic 1], [Automatic 2], [heating].
E E 20 - 90°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

operating mode: [Automatic 1], [Automatic 2], [Reducing].
E E 10 - 90°C 10 °C 1 °C
T-Flow Cooling Only if parameter [HC Function] = 1
Setting the inflow target temperature when cooling mode is active. E E 8 - 30°C 18 °C 1 °C
T-Outside lim day Only if parameter [Pump Mode] = 1
Setting the automatic summer shutdown of the heating system. If the outside temperature
measured and averaged out by the controller exceeds the set value by 1 K, the heating circuit
is switched off. The heating is enabled again once the outside temperature falls below the set
heating 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 time
(functionality as for parameter [T-Outside lim day]). E E Off, 10 - 40 °C 10 °C 0.5 K
Accep limit T-Room Only if the room temperature controller is connected and assigned to the heating c

Only if the solar system ROTEX is connected and parameterised:
Room temperature, above which heat energy from the connected ROTEX solar system is made
available at a heat demand.
If the room temperature at the room temperature controller is greater than the value set here +
0.5 K, then the demand of the heat circuit is suppressed.
E E 0 - 20°C - - - - 1 °C
Heat-Slope Only if parameter [HC Function] = 0
Setting the heating curve. The heating curve reflects the dependence of the set inflow temper-
ature 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 from
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 recirculation pump
continues to run until the next heating cycle following a heat demand during the setback time.
1-20: Causes a correction of the set flow temperature (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, from 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 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 00:00 15 min
Opt Reduced Function for preventing the HPSU compact starting up shortly before the end of the parameter-
ised heating time (format hh:mm). E E Off
On Off -
T-Frost Protect Off: No frost protection of the heating circuit
Otherwise: If the outside temperature falls below the programmed value, the system switches
into the frost protection mode (switches the pumps on). The function ceases once the outside
temperature has risen to the set value +1 K. E E Off,
-5 to +5 °C

Insulation Setting the insulation standard of the building. This affects the way the heating curve and the
heating times automatically adapt to the outside temperature. E E Off

Start T-Out Cooling Can be used only if the assigned heat generator has a cooling function.
Setting from which outdoor temperature initiates cooling mode. The actuation logic for the mixer
motor is reset to heating mode when the outside temperature falls below the set value less 1 K. E E 20 - 45°C 24 °C 1 K
Max T-Out Cooling Can be used only if the assigned heat generator has a cooling function.
Setting for the outside temperature from which the lowest cooling inflow target temperature (pa-
rameter [T-Flow cooling start]) and the highest target value for the room temperature

(parameter [T-Room max cooling]) should be set.
E E 20 - 45°C 35 °C 1 K
T-Flow cooling start Can be used only if the assigned heat generator has a cooling function.
Setting the cooling inflow target temperature at the start of cooling mode

E E 5 - 25°C 18 °C 1 K
T-Flow cooling max Can be used only if the assigned heat generator has a cooling function.
Setting the minimum cooling inflow target temperature. This is kept constant relative to the

outside temperature (parameter [Max T-Out Cooling]).

T-Room start cooling Can be used only if the assigned heat generator has a cooling function.
Setting the target value for the room temperature at the start of cooling mode (parameter

T-Room max cooling Can be used only if the assigned heat generator has a cooling function.
Setting the maximum target value for the room temperature. This is kept constant relative to the
outside temperature (parameter [Max T-Out Cooling]).
