B BUS
- 2-conductor cable, min. size 1 mm 2 .
-
Total
length of the BUS connection: 40 meters (heating board A1 / control box connection).
- To be connected to the heating board A1.
C Control box power supply
- 230 V, single-phase, 50 Hz + ground (Class I).
- It must be supplied from a protection and disconnect device in compliance with current regulations.
- Cable 3G 1.5 mm
2 .
- To be connected directly on circuit breaker Q1 of the box (Terminals U and N ).
Note : The control box is supplied by the BUS.
D Outside temperature sensor
- 2-conductor cable, min. size 0.5 mm 2 .
- Maximum length 25 meters.
- To be connected to the heating board A1.
E Generator control
- Shielded cable with 2 twisted pairs (shielding on generator side).
• 1 pair for generator on.
• 1 pair for the generator alarm signal.
- Min. cable size: 0.5 mm
2
.
- Maximum length 25 meters.
- To be connected to the heating board A1.
F Supplementary boiler authorisation
- Potential-free changeover contact, available on the box's terminal strip (terminals A , B , C ).
- 2 A resitive at 230 Vac maximum.
- Actuated contact = boiler authorised.
- This signal is not mandatory if the supplementary valve is connected.
G Boiler alarm unavailable (as required)
- A contact from the boiler can possibly be connected on the heating board A1 for signalling on the control box and closure
of the supplementary valve.
- This contact must be potential-free and of good quality.
- Contact open = alarm.
- A maximum connection length of 25 meters and size 0.5 mm
2 .
H Boiler supplementary valve control (if any)
- "On/Off" control signal, 230 V / 50 Hz (30 VA maximum) available on the box's terminal strip:
- terminal 2 = common (connected to the Neutral)
- terminal 1 = valve opening control
- terminal 3 = valve closing control
- It is possible to connect either a 3-point valve (3 wires) (available as an accessory), or a spring type return valve (2
wires).
- Minimum cable size 0.75 mm 2 .
J Circulator (if any)
- It is possible to supply a circulator with 230 V / 1 / 50 Hz directly via the box's terminal strip (Terminals 4 - Neutral / 5 -
Phase / Ground).
- Maximum current 1.6 A (for a superior current strength, the signal must be relayed).
- Cable 3G 1.5 mm
2 .
- The circulator must have its own thermal protection (not supplied).
L Water temperature sensor (installation return)
- Sensor delivered with a cable measuring 3.5m long.
- This connection may be extended with a 2-conductor cable (minimum 0.5 mm
2 cross-section) and with a maximum
length of 25 meters.
- To be connected to the heating board A1.
X Pilot wire for electric convectors (if any)
- To send shut-down, "
Anti-freeze
" (prolonged absence) or "
Eco
" orders to electric convectors in zone 2. Convector
control (not supplied) must be adapted to receive this type of signal (standard GIFAM 4). Consult the manual of the
electric convectors.
- 230 VAC signal from the heating board A1.
- 1.5 mm
2 single-pole cable adapted for the operating voltage.
- Max. number of convectors controlled by the pilot wire: 20.
-
Note : The electrical power supplied to the convectors must be the same as that of the control.
Note: ensure that the ground connections of the various system components are interconnected.
