WIRING
All wires must be sized per NEC (National Electrical Code) or CEC
(Canadian Electrical Code) and local codes. Use Electrical Data table
MCA (minimum circuit amps) and MOCP (maximum over current
protection) to correctly size the wires and the disconnect fuse or breakers
respectively. Per the caution note, only stranded copper conductors with
a 600 volt rating and double insulated copper wire must be used.
The use of BX cable is not recommended.
Recommended Connection Method for Power and
Communication Wiring - Power and Communication
Wiring:
The main power is supplied to the outdoor unit. The field supplied 14/3
power/communication wiring from the outdoor unit to indoor unit
consists of four (4) wires and provides the power for the indoor unit.
Two wires are high voltage AC power, one is communication wiring and
the other is a ground wire.
Recommended Connection Method for Power and
Communication Wiring (To minimize communication wiring
interference)
PowerWiring:
The main power is supplied to the outdoor unit. The field supplied power
wiring from the outdoor unit to indoor unit consists of three (3) wires
and provides the power for the indoor unit. Two wires are high voltage
AC power and one is a ground wire.
To minimize voltage drop, the factory recommended wire size is 14/2
stranded with a ground.
Communication Wiring:
A separate shielded Stranded copper conductor only, with a 600 volt
rating and double insulated copper wire, must be used as the
communication wire from the outdoor unit to the indoor unit. Please use
a separate shielded 16GA stranded control wire.
CONTROL SYSTEM
The indoor unit is equipped with a microprocessor control to perform
two functions:
1. Provide safety for the system
2. Control the system and provide optimum levels of comfort and
efficiency.
The main microprocessor is located on the control board of the fan coil
unit (outdoor units also have a microprocessor) with thermistors located
in the fan coil air inlet and on the indoor coil.
The heat pump units have a thermistor on the outdoor coil. These
thermistors monitor the system operation to maintain the unit within
acceptable parameters and controls the operating mode.
Wireless Remote Control
Fig. 9 — Wireless Remote Control
1. A wireless remote control is supplied for system operation for system
operation of all high wall units.
2. Each battery operated wireless (infrared) remote control may be used
to control more than one unit.
WIRED REMOTE CONTROL (OPTIONAL)
P/N KSACN0401AAA
1. Optional wired remote controller used for system operation of all high
wall units.
2. Kit includes a wired remote controller and a connecting cable.
3. Connect with wire terminal between remote controller and indoor
unit.
4. Display in F or C and temperature increments every 1F or every
1C.
EQUIPMENT DAMAGE HAZARD
Failure to follow this caution may result in equipment damage or
improper operation.
Wires should be sized based on NEC and local codes.
Use copper conductors only with a 600 volt rating and double
insulated copper wire.
CAUTION
EQUIPMENT DAMAGE HAZARD
Failure to follow this caution may result in equipment damage or
improper operation.
Be sure to comply with local codes while running wire from the
indoor unit to the outdoor unit.
Every wire must be connected firmly. Loose wiring may cause
the terminal to overheat or result in unit malfunction. A fire
hazard may also exist. Ensure all wiring is tightly connected.
No wire should touch the refrigerant tubing, compressor or any
moving parts.
Disconnecting means must be provided and shall be located
within sight and readily accessible from the air
conditioner.
Connecting cable with conduit shall be routed through the hole in
the conduit panel.
