Low Voltage Wiring
Thermostat Location
Location of the thermostat or zone sensor is an important element of ef- fective room control.
Areas where the thermostat or zone sensor should not be located include: Behind doors or corners; Near hot or cold air ducts; Near radiant heat (heat emitted from appliances or the sun); Near concealed pipes or chimneys; On outside walls or other non conditioned surfaces; In
Controls Using 24 VAC
Before installing any wire, refer to the electrical access locations on the unit submittals located on page 10.
Ensure that the AC control wiring be- tween the controls and the unit’s ter- mination point does not exceed three
(3)ohms/conductor for the length of the run.
Note: Resistance in excess of
Check all loads and conductors for grounds, shorts, and
Use copper conductors unless other- wise specified.
Do not run the AC low voltage wiring in the same conduit with the high volt- age power wiring.
