Wiring Information – 5 core interconnecting
When using a 5 core interconnecting cable the
wiring is very simple. Outdoor to Indoor
W to W
1(L) to 1(L)
2 (N) to 2 (N)
S to S
E to E

6
Wiring Information – 4 Core Interconnecting
For instances where a 4 core interconnecting is to
be used we can bypass the 1W standby relay and
power the condenser directly from the mains
supply
This reverts the system back to 5W standy power
usage, the same as all other manufacturers
To achieve this, when the unit is powered down,
we need to move the brown spade connection
from the W terminal and replace it onto the spare
connection on the 1(L) terminal
You then wire with a 4 core cable and miss W at
both units

Wifi & Controller Installation
The connections for both the wifi adapter and a
hard wired controller are on the display board
To access it, lift up the fascia and remove the
screw that is holding it in place
Ease the display board from the fascia holdings
and it will hang from the connection made to the
indoor pcb
