Aqu:
A water Aquastat is wired on Input2.
If over temperature is reached (contact open)
then:
- if "inst"="Act or SEP", Pump1 circulation is
stopped & mixing valve is closed.
- if "inst"="2P.x", direct circuit Pump2 circula
tion is stopped
HC:
A Heat/Cool switching signal is wired on In-
put1 to manage the working mode of the in-
stallation. (contact between point 2 and In1 or
phase signal on In1)
Heating = no signal (open circuit ) Cooling =
Phase signal (closed circuit).
C_b:
A pump signal from a connecting box is wired
on Input1 to manage the working of the
pump1.
(contact between point 2 and In1 or phase
signal on In1)
Heating = no signal (open circuit )
Cooling = Phase signal (closed circuit).
- if "inst"="Act or SEP", water floor Pump1
circulation is stopped & mixing valve is closed.
- if "inst"="2P.x", direct circuit Pump2 circula-
tion is stopped.
_ _ _ OUSE Outside sensor menu:
Yes: Wired outside sensor is installed.
13
No: Installation without outside sensor
The regulation will work like a "thermostat"
with a adjustable "Wcal" temperature injected
on the circuit.
rF: Wireless RF outside sensor is installed.
The following parameter is only available if no outside sensor is installed and the "OUSE" parameter is set to "no".
_ _ _ OU t Outside temperature:
This menu is used to fix the outside tempera-
14
ture to have the desired calculated water
temperature in accordance to the curves.
Example:
Ou t = 0°C, Curv = 1
Wcal => 40°C
You could adjust with more accuracy the
"Wcal" temperature since the main screen
with the "Comfort" and "Reduced" offset.
The following parameter is only available if "OUSE" parameter is set to "rF"
RADIO-CONFIGURATION with RF sensor for outdoor temperature
Same radio configuration sequence as parameter 8 "trF1" above.

PR For an installation requiring additional external
PE
(Efficiency
heat (e.g. electrical back-up, boiler, heat pump).
Point)
This function can be activated in order to control a
15
backup stage 2 heat generator using the free
contact (5A 220V AC) "Heating output".
The HC signal
could be done by a
heat pump.
