4.3.4 - OTHER CONTROL CONNECTIONS
Caution:
To avoid problems related to electromagnetic disturbances, do not route these cables near power cables.

Possible connections to be
made depending on the
applications
A) BUS
- 2-conductor shielded cable, minimum size 1 mm_ with shielding grounded on indoor unit side (*).
- Total length of the BUS connection: 40 meters (indoor unit / control box connection + indoor unit / 2-zone module
connection, if any).
- To be connected to the (+) and (-) terminals if terminal strip XB.
(*) Refer to the ground shielding principle in paragraph 4.3.3.
B) Outside temperature sensor
- 2-conductor cable, min. size 0.5 mm
- Maximum length 25 meters.
- To be connected to the heating board A1.
- Note:
This sensor must be located outside in a location that is representative of the temperature to be measured (on a wall facing
North / North-west) and located away from parasitic heat sources (chimney, thermal bridge, etc..) and sheltered from
inclement weather (under a roof overhand, for example).
C) Outdoor unit control connection
- 2-conductor shielded cable with shielding grounded on both the outdoor unit and indoor unit side.
- Minimum cable size: 0.75 mm
- Maximum length 70 meters.
- Connection as per paragraph 4.3.3.
D) Module additional heating load shedding signal (if installed)
- Two possibilities:
1) By a "remote info" signal coming from the electrical utility meter: 1 twisted pair (6/10) cable with shielding (shielding
grounded on module side).
2) By a good quality, potential-free external contact.
- Contact closed = load shedding of the additional electric heating.
- 2-conductor cable, min. size 0.5mm
- Maximum length 25 meters.
- To be connected to the heating board A1.
