th1: the wired room thermostat should be
wired on Input1 because "th" parameter is set
to "YES")
no: Input1 not used (nothing wired)
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)
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 )
_ _ _ in2
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)
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-
Connection of wireless room thermostat is only possible using appropriate device.
