Communication line (BUs)
- 2-conductor shielded cable, minimum size 1 mm
2
with grounded shielding on heat pump side (*).
-
Total
length of the BUS connection: 40 meters (control unit conne 2-zone module, if any or DHW preparation
kit, if any ).
- To be connected to the (
+
) and (
-
) terminals if terminal strip.
(*) Refer to the ground shielding principle in paragraph 6.4.
Outside temperature sensor
- 2-conductor cable, min. size 0.5 mm
2
.
- Maximum length 25 meters.
- To be connected to the (
s13-1
) and (
s13-2
) terminals if terminal strip.
-
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). See paragraph 5.2.
electric support heater load shedding signal (if any)
- 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 heat pump side).
2) By a good quality, potential-free external contact.
- Contact closed = load shedding of the electric support heater.
- 2-conductor cable, min. size 0.5mm
2
.
- Maximum length 25 meters.
- To be connected to the system board
A1.
eCO signal for remote controls (if any)
- 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 system 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.
