Selecting „no thrF“ disconnects the RF thermostat from the Controller and
discontinues the room temperature plug-in function respectively.
Connection of wireless room thermostat is only possible using appropriate device.
The following parameter is only available if “th” parameter is set to “rF”
and if “inst” parameter is set to “
2P.1
” or “
2P.2
” (2 pumps mode)

SYSTEM PARAMETERS
_ _ _
in1
11
Wired Input1 selection: (
5.5.1).
th1:
the wired room thermostat should be
wired on
Input1
because “
th
” parameter is set
to “
YES
”)
no:
Input1 not used (nothing wired)
no
th1
un-adjustable
no, Aqu,
HC
or
C_b
Aqu:
A water Aquastat contact is wired on Input1.
If over temperature is reached (contact open)
then Pump1 circulator is stopped and the
mixing valve is closed.
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)
The HC signal
could be done by a
heat pump.
Check the electri-
cal compatibility
before connection
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
)
Pump ON = Phase signal (closed circuit)
Pump OFF = no signal (open circuit )

Wired Input2 selection: (
5.5.2).
th2:
the wired thermostat for second pump
system should be wired on
Input2 (because “
th
” parameter is set to “
YES
”
and “
inst
” is set to “2P.x”)
no:
Input2 not used (nothing wired)
no

not-adjustable
no, Aqu,
