E) Pilot wire for electric convectors (if any)
- The pilot wire sends shut-down, "anti-freeze" (long term absence) or "Economy" mode instructions to the electric
convectors in zone 2, and possibly in the case of 1 floor zone or 1 terminal unit zone applications.
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.
- 1.5 mm
2
single-pole cable adapted for the operating voltage.
- Max. number of convectors controlled by the pilot wire: 20.
-
To be connected to the heating board A1.
GB
- Note:
The electrical power supplied to the convectors must be the same as that of the module.
F) ECO signal for remote controls (if installed)
- In order to send reduced mode orders (Eco or standby) to the terminal unit remote control units in the case of
applications such as 1 terminal unit zone or 2 mixed zones.
- In the form of a potential-free contact which can used in VLV (Very Low Voltage), 2A max.
- To be connected to the heating board A1.
- Note:
The contact can control up to 10 RCC10 (70250051) or RCC20 (70250052) type controls.
Consult the terminal unit and remote control documentation to connect this contact.
CONTROL PART CONNECTION DIAGRAM
- Route the control cables on the right side of the board.
- Pass the pilot wire (230 V) on the left side of the board.
