The standard Climate Control Option X is a remote
thermostat connection terminal block. See Figure 16
for wiring diagram. Compatible thermostats are listed
in Table 4.
The Climate Control Option E is an electronic,
programmable thermostat and a humidistat. The sub
base of the thermostat and the humidistat are factory
wired to the front panel of the unit. See Figure 16A
for wiring diagram. Compatible for use with Energy
Recovery Ventilator or Ventilator.
The Climate Control Option F is an electronic, non-
programmable thermostat, timer and a humidistat.
The sub base of the thermostat and the timer are
factory wired to the front panel of the unit. See Figure
16B for wiring diagram. Compatible for use with
Energy Recovery Ventilator or Ventilator.
The Climate Control Option G is an electronic,
non-programmable thermostat and humidistat. The
subbase of the thermostat is factory wired to the front
panel of the unit. This option is compatible for use
with the optional CS2000 Energy Control Monitor
and a terminal block is provided for connection to the
CS2000. See Figure 16C for wiring diagram.
Compatible for use with Energy Recovery Ventilator
or Ventilator.
NOTE: The CS2000 (or other field provided means
to control ventilation) must be used if any of
the mechanical (motorized) ventilation
options are installed.
WIRING – MAIN POWER
Refer to the unit rating plate and/or Table 2 for wire
sizing information and maximum fuse or “HACR
Type” circuit breaker size. Each unit is marked with a
“Minimum Circuit Ampacity”. This means that the
field wiring used must be sized to carry that amount of
current. Depending on the installed KW of electric
heat, there may be two field power circuits required. If
this is the case, the unit serial plate will so indicate. All
models are suitable only for connection with copper
wire. Each unit and/or wiring diagram will be marked
“Use Copper Conductors Only”. These instructions
MUST BE adhered to. Refer to the National Electrical
Code (NEC) for complete current carrying capacity data
on the various insulation grades of wiring material. All
wiring must conform to NEC and all local codes.
The electrical data lists fuse and wire sizes (75° C
copper) for all models, including the most commonly
used heater sizes. Also shown are the number of field
power circuits required for the various models with
heaters.
The unit rating plate lists a “Maximum Time Delay
Relay Fuse” or “HACR Type” circuit breaker that is to
be used with the equipment. The correct size must be
used for proper circuit protection, and also to assure
that there will be no nuisance tripping due to the
momentary high starting current of the compressor
motor.
The disconnect access door on this unit may be locked
to prevent unauthorized access to the disconnect.
See Start Up section for information on three phase
scroll compressor start-ups.
The field wiring connections are located behind the top
and hinged panel in the circuit breaker panel. See
Figure 14.
WIRING – LOW VOLTAGE WIRING
230/208V, 1 PHASE AND 3 PHASE EQUIPMENT
DUAL PRIMARY VOLTAGE TRANSFORMERS.
All Equipment leaves the factory wired on 240V tap.
For 208V operation, reconnect form 240V to 208V tap.
The acceptable operating voltage range for the 240 and
208V taps are as noted in Table 3.
