Step 4.
Pass the remote controller cable through the two open
cable ties (factory supplied).
Connect the remote controller cable to the Interface PCB
( A1P) by inserting the remote controller cable plug into
socket S8. (Fig.4)
Wire the shield wire of the remote controller cable to
the shield fastening point. (Fig.4a)
Note 4:
When installing KRCSO1-1 (option) or BRCSZC (option),
do not tighten the cable ties until you have passed all
cables through the 2 open cable ties.
Tighten the 2 cable ties to anchor. (Fig.4a)
Step 5.
Wire the zone motors to the zone motor terminal blocks
X4M (Fig.5) (zone motor field supplied)
Pay close attention to the terminal labelling.
When wiring “motor open motor closed” zone motors
ensure open, close & neutral wires are wired to
respective terminals.
Note 5:
For zone motors that require earthing.
(Ensure zone motors are earthed to the individual earth
connections provided.)
Open = Active
Closed = Active
Common = Neutral
When using a spring return zone motor only use the
Open & Common terminal connections.
By using a cable tie (field supplied), secure the zone
motor leads to the anchor as shown in (Fig.5) ensuring
the cable tie is secured to the outer insulation of the
cable.
Note 6:
Refer to DSI settings on page 12 before installing the
zone controller box cover.
Step 6.
Install the indoor unit electrical box cover and the zone
control box cover. (Fig.6)
Ensure the cover fits tightly and cables are not in contact
with the underside of cover or cover edges.
