Screw terminal blocks for connection to the Pilot electronics board
1.12-point terminal (the circuit board marked Ext. ; Pisc. ; Amb 1 ;
Amb 2 ; Del ; HP/HC)
Ext.
(a)
: Outdoor sensor (supplied, mandatory connection)
Pisc.
(b)
: Swimming pool aquastat or sensor. See § "Circuit 1
temperature control" to set the circuit 1 swimming pool
sensor
(1)
Amb 1 : Circuit 1 room thermostat (potential-free dry contact, non
chrono-proportional, no IPD, etc...)
or room temperature sensor with display for circuit 1
to set the circuit 1 temperature control or to control the
swimming pool fl ow for circuit 1
(1)
Amb 2 : Circuit 2 room thermostat (potential-free dry contact, non
chrono-proportional, no IPD, etc...)
or circuit 2 DHW aquastat
See § "Circuit 2 temperature control" to set ambient
temperature or DHW temperature on
circuit 2
Del
: Load shedding input, used to partially or completely stop
electrical back-up and the Heat Pump when the electricity
is needed for other household uses.
Remove the existing electrical bridge and connect the
load shedding device’s potential-free dry contact.
Set to parametre PAR.218
(2)
(see § "Setting operating
parametres") which determines the level of authorisation
for the electrical back-up and Heat Pump to run at (the
factory setting is total load shedding for the Heat Pump
and electrical back-up).
HP / HC : Peak-time / off -peak operation, used to stop partial or full
operation of the electrical back-up and Heat Pump during
peak hours.
Remove the existing electircal bridge and connect the
potential-free dry contact PT/OP.
Adjust to setting PAR.217
(2)
(see § "Setting operating parametres") which determines the level of authorisation for the electrical
back-up and Heat Pump to run at (the factory setting is only for load shedding on the electrical back-up).
The HP / HC and DEL contacts can also be used for load shedding
on peak day pricing. By programming PAR.217 or PAR.218 on 7,
only the boiler will run when the dry contact is open.
(1)
: For a permanent swimming pool ( winter).
If the pool is not permanent, please use the summer swimming pool control kit (Ref. 751006).
(2)
: If both settings PAR.217 and PAR.218 are activated at the same time, the lowest authoristion level will be used on both inputs in case of
simultaneous load shedding.
2. 2-point terminal (marked Chaud on PCB.)
Chaud. : on / off output (dry contact) to connect to the room thermostat input on the existing boiler.
see § "Back-up section" for setting the boiler back-up.
The boiler normally commands its own circulator pump.
If this is not the case, relay the "chaud" dry contact so that one relay feeds two contacts:
- the fi rst contact
(NO) is used to start the burner on the boiler (room thermostat input).
- the second change-over contact is used to supply the boiler’s heating circulator pump and to keep it running a few minutes (approx.5)
after the boiler has stopped.

3.4.2 - Connecting the Pilot
• In order to avoid any problems which may occur when reading the temperature sensors, wire the control
independently of any power cables (raceways) and avoid distribution boxes.
• The conductors must be made from electrolytic copper (there must be no rust on the stripped connection strands).
• Telephone wire must not be used (too brittle for connections).
• The diametre of the control cables must be between 0.5 and 1mm².
For a standard installation with one radiator circuit, the outdoor temperature sensor

and if applicable the room thermostat
