Parameter
Flow Sensor Status Activation of flow measurement (FlowSensor) in the flow sensor
0: function active; 1: function inactive
V min Minimum flow (measured on the flow sensor)
The parameter depends on the set value in parameter (INDOOR UNIT)
V max Upper limit of flow (measured on sensor t
value in parameter [INDOOR UNIT].
V var Current minimum necessary volume flow in the system (calculated value, not con-
figurable)
V hyst Hysteresis for flow sensor
Relay Test In this context menu we can actuate individual relays or several relays manually.
Sensor Test In this context menu we can manually call up measured values of the individual
sensors. These can deviate from the displayed values in the other menu levels
since here we show the current unfiltered measured values werden. In the individ-
ual menu levels, on the other hand, we show the filtered measured values relevant
for the controller.
Parameter Reset Setting value for resetting all parameters at this level to the individual standard val-
ues.
0: off; 1: on
Operating Mode Parameter for setting the operating mode of the internal heating circuit.
At the setting "- - - -" the rotary switch applies to the control of the heating circuit.
With setting the operating modes "Readiness/OFF" and "Summer time" on the ro-
tary switch this has a reducing effect on all heating circuits and consumer circuits
in the entire system.
0: ---
1: readiness
2: setback
3: heating
4: cooling
5: summer
6: automatic 1
7: automatic 2
HC Function Various different functionalities can be allocated to the heating circuit.
0: Standard heating circuit regulation
1: Regulating to a fixed set flow value, depending on the heating or setback mode
T-Frost Protect If the outdoor temperature falls below the programmed value, the system switches
to the frost protection mode (switching the pumps on).
Insulation This parameter can be used for setting the insulation standard of the building. This
affects the heat curve and the heating and cooling times.
0: off
1: low
2: normal
3: good
4: very good
Screed This parameter can be used to activate the function for screed drying. The flow
temperature is regulated according to the parametrised screed programme. The
day on which the screed function is activated does not count towards the running
time of the screed programme. The first day starts as the day changes on the first
day at 00:00. On the day of activation we heat for the remaining time at that for the
programme of the first day.
Screed Programme In this input we can parametrise the sequential programme of screed heating up.
We can set an individual flow temperature for each day for the duration of a maxi-
mum of 28 days. The end of the screed programme is defined by the 1st. day at
set value setting "- - - -".
