EXCLUSIVELY connect the water sensor
(Ref. 710029).
If DHW is produced by a domestic hot water tank:
- Place the sensor in the well of the tank to inspect the
temperature of the hot water immediately available.
- Connect the water sensor to the «
BAL
» terminals of the
PRIMO
Pilot
.
4.4.4 - Domestic water sensor
The connection of the exterior sensor is recommended (if it is not the
heat curve is calculated using the temperature read by the air sensor).
Place the sensor on the coldest exterior wall of the building (usually
the north-facing wall). It must not be exposed to the morning sun.
It is preferred to mount the exterior sensor in the middle of the wall of
the building or of the heating zone, at least 2.5m above ground level.
Do not place the sensor:
- above windows, doors, air exhausts, or other heat sources,
- beneath balconies or gutters
To prevent mistakes in the temperatures measured due to air
circulation, insulate the exremities of the sensor’s electrical conduit.
Do not paint the exterior sensor.
4.4.3 - Exterior sensor
Note :
After connection, go to the «
DISPLAY
» menu and check that the
«
EXTERIOR
» screen appears with the value read by the probe.
If not, check the connection of the probe or the pilot connector.
4.4.5 - Underfl oor safety device of the 65°C
safety aquastat (OPT) with manual reset
(OPT)
Use the additional wiring provided in the kit (
Ref. 710111
) to protect
the fl oor heating circuit.
When the installation has a DHW tank, do not exceed a DHW
setpoint equal to 55°C.
CAUTION WHEN THE INSTALLATION INCLUDES A SANITARY
TANK !
1. The DHW setpoint setting must be less than 55 ° C.
2. Place the safety aquastat as close as possible to the
common outlet of all the underfl oor heating loops (that
is to say just upstream of the fl oor outlet manifold) so as
to move it away from the Pilot’s fl oor outlet outlet and in
order to avoid its triggering after a load of the domestic
hot water tank.
In an installation with both thermostatic valves and a room
temperature thermostat, the radiator(s) in the room in which the
thermostat is located
MUST
be equipped with a manual air valve(s).
It is mandatory to install the ambient temperature control on an
interior wall of the room for control by the appliance and not a wall
that lets out onto the outside of the building.
Installation against an exterior facing wall is prohibited.
Do not place the ambient temperature controller too close to a
window, a curtain, or a door. Avoid placing it in an alcove, a closet,
or behind drapes.
Do not place above a heat source (radiator,...)or against a wall with
a chimney.
Do not place in reach of sun’s rays, or near powerful lighting.
Place the sensor 1.50m above fl oor level, and at least 50cm away
from neighboring walls. Insulate the extremeties of the electrical
cabling of the installation on the side of the appliance to prevent
air currents from infl uencing the measures taken.
EXCLUSIVELY connect either :
- The AMBIENT TEMPERATURE SENSOR
with DISPLAY (Réf. 751009)
- The AMBIENT TEMPERATURE RADIO
THERMOSTAT (Réf. 770001)
All other thermostats which are chronoproportional
may cause malfunctioning and render the warranty
null and void.
4.4.2 - Ambient temperature control
- Connect the two wires of the connecting cable on terminals
A
and
B
of the «
Modbus
» terminal while taking care to respect
the polarity
A
/
B
(terminal
A
of the
Pilot
to be connected to
terminal
A
of the heat pump; the same for terminal
B
).
- Connect:
- the brown wire to A
- the white wire to B
- the black wire to GND on both appliances.
- If you are using a diff erent cable, respect the polarity of A and B as
well as the connection of the shielding on 0V on both appliances.
4.4.1 - Control connection towards the Heat
pump
Ensure that the connecting cable is distanced
from any source of electrical disturbance
(ex: washing machine, neon lighting, power
supply cable....)
Plan for the appropriate length of
cable between the pilot and the heat
pump. Do not hesitate to cut the cable
to the appropriate length to
AVOID
LOOPS
