3.1.2 Water floor heating (mono zone) managing hydraulic circuit
and a boiler.
Equipments:
• 1 Thermostat BT-D02 RF (or BT-A02 or BT-DP02 RF)
• 1 Wall Receiver BT-WR02 RF (or BT-FR02 RF) for driving an actuator
• 1 Central Unit BT-CT02 RF
• 1 Receiver BT-WR02 HC RF for driving a boiler, or an heat pump
(BT-WR02 RF if driving a pump)
For a correct installation, refer to dedicated user guides of each product, then:
WIRING CONNECTION:
• Connect first receiver to the actuator (eg. 22C – 22CX series)
• Connect second receiver to the bolier (or pump)
VIRTUAL – RF CONNECTION:
• Create a virtual room (zone 1) on the Central Unit BT-CT02 RF
1. Pair as Heating Device the thermostat to the Central Unit BT-CT02 RF.
2. Pair as Heating Device the first receiver that drives the actuator
(BT-WR02 RF or BT-FR02 RF) to the Central Unit BT-CT02 RF
(Heating Parameter = Hydraulic).
3. Pair the other receiver BT-WR02 HC RF (or RF BT-WR02 RF if driving a
pump) to the Central Unit BT-CT02 RF as a hydraulic circuit then select
the hydraulic circuit.
Devices configuration: go in the zone, select the information menu,
select the receiver and the hydraulic type, then the hydraulic circuit
(refer to HYDRAULIC SYSTEM PAIRING chapter on Central Unit user guide).
Notes:
A thermostat can drive several receivers in the same zone. We can create
several zones in the Central Unit.
It is possible to link each receiver to a specific hydraulic circuit, managing its
pump by the Central Unit.
