HOW TO WIRE & INSTALL BRC24Z4 / BRC24Z8
Note 1:
You may find it easier to wire the control box before mounting the box to the indoor unit, for example when the
ceiling space is tight. If you choose to wire the control box before mounting it to the indoor unit ensure to allow
adequate cable length.
Note 2:
Please refer to Electric Wiring Work Pg. 14 of this manual to determine cable connection style and to ensure the
wiring connections are appropriate.
Note 3:
Ensure all field wiring passes through the black plastic wiring bushes located at the bottom of the controller box.
Step 1.
Attach the Zone control box to the body of the indoor
unit using the (4) M6 screws supplied. (Fig.1)
Be careful not to cause damage to the internal
components of the Zone control box when attaching the
box to the indoor unit.
Step 2.
Pass both ends of the field supplied cable through the
plastic bushes of the indoor unit electrical box and zone
controller box. Strip both ends of the cable. Connect the
stripped wires to the LN
box and the zone controller box.
By using a cable tie (field supplied), secure both ends of
the LN cable to the anchor as shown in (Fig.2)
ensuring the cable tie is secured to the outer insulation
of the cable.
Step 3.
Connect the loose end of P1 P2 communication cable to
the P1 P2 terminal block of the indoor unit electrical box.
