•
Near radiant heat (heat emitted from appliances or the
sun)
•
Near concealed pipes or chimneys
•
On outside walls or other non conditioned surfaces
•
In airflows from adjacent zones or other units.
Controls Using 24 Vac
Before installing any wire, refer to the electrical access
locations in the
of this manual.
Ensure that the AC control wiring between the controls
and the unit termination point does not exceed 3 Ohms/
conductor for the length of the run.
NOTICE
Component Failure!
Resistance in excess of 3 Ohms per conductor could
result in component failure due to insufficient AC
voltage supply.
Check all loads and conductors for grounds, shorts, and
mis-wiring. Use copper conductors unless otherwise
specified. Do not run the AC low-voltage wiring in the
same conduit with the high voltage power wiring.

For controls using DC analog input/outputs, see
appropriate installation, operation and diagnostic
manuals for connection, CNT-SVX11*-EN (ZN524). For
installation, operation and programming see BAS-

Blower Motor Speed-Tap Retrofit
Note:
For GEH/V 0.5 to 5 ton units only.
Motors installed in the unit include 4-speed or 3-speed
configurations. All voltages include a 4-speed
configuration, with the exception of 380V, 415V, 460V
which contain a 3-speed arrangement and 575V which
contains a 2-speed arrangement. To modify the rpm of the
motor, the following steps must be followed.
WARNING
Hazardous Voltage!
Failure to disconnect power before servicing could
result in death or serious injury. Disconnect all electric
power, including remote disconnects before servicing.
Follow proper lockout/tagout procedures to ensure the
power can not be inadvertently energized.
