Element
1 Signal cable of the solar energy kit
2 Control panel cable
3 Room thermostat cable
5 Probe cable for Tw2
9 Domestic hot water pump control cable
10/11/23 3-way valve control cable
12 Probe cable for T5
13 Booster heater control cable
15 Unit power cable
(a): Minimum cable cross-section AWG18 (0.75 mm
(b): The thermistor and the connection cable (10 m) are delivered with the domestic hot water tank (T5) or with the zone
2 outlet temperature probe (Tw2).
(c): Chap. 9.7.4 Specifications of standard wiring components.
NOTE
Please use H07RN-F for the power cable. All the cables are connected in high-voltage except for the thermistor cable
and the user interface cable.
• The instruments must be earthed.
• All external high-voltage loads, if in metal or with earthing connection, must be earthed.
• All external load currents must be lower than 0.2A, if the single load current is higher than 0.2A, the load must be con-
trolled by an AC contactor.
• The ports of the wiring terminals R1, R2, and DFT1, DFT2 only supply a signal switch. Please refer to Chap. 9.7.6 To
obtain the position of the ports in the unit.
