The simplified connection diagram at left shows the factory
configured wiring set for 240V operation. If you are going to use
208V exclusively, switch the two (2) black wires on the 240V post
of the primary side of the transformer to the 208V post. This will
ensure correct secondary (low)voltages for the unit. This is only
required on remote thermostat units.
CAUTION
If the supply voltage is 208V, the low
voltage transformer MUST be wired for
208V operation Failure to do so will result
in lower contro_ voltages to the unit and can
damage _ow voltage components
Remote Thermostat Unit Operation
Theseunitsare controlledby the use of a remotethermostat thatwill
cycle the unitto maintaindesired room temperature.Seethermostat
operating instruction sheet for details.
The fan speed switch controlshighand low speed fan operation. Itis
located on the control panel and isindependent of the thermostat.
Auto Changeover Thermostat
A singlestage heat/coolthermostatwith auto changeoveris needed.
The wiring scheme is the same as the manualthermostat.
Remote Thermostat Installation
Follow Steps 1through 5 (pages 12and 13), then:
6. Locate the terminal strip on the front of the control box (See
Figure9). Attach thethermostat subbasewires(field supplied)
to the appropriately labeled terminals in accordance with the
wiring diagram on the side of the chassis.
7. Carefullyroute the wiresalongside the conduitor service cord.
Attach the other end of the wires to the appropriate terminals
on the thermostat subbase. Seethe thermostat directions for
proper wiring and mounting ofthe thermostat.
