Guidelines for wire sizes and lengths are
shown in
. The total
resistance of these low voltage wires must
not exceed 2.5 ohms per conductor. Any
resistance greater than 2.5 ohms may cause
the control to malfunction due to excessive
voltage drop.
•
Do not run low-voltage control wiring in
same conduit with high-voltage power
wiring.
Wiring
1. Run wires between the unit control panel and the
zone sensor subbase. To determine the number of
wires required, refer to the unit wiring diagrams.
2. Connect the wiring to the appropriate terminals at
the unit control panel and at the zone sensor
subbase. In general, zone sensor connections to the
unit use the convention of connecting zone sensor
terminals to like numbered unit terminals (1 to 1, 2
to 2, etc.).The connection detail is shown on the unit
wiring diagrams, which are located in the unit
control panel.
3. Replace the zone sensor cover back on the subbase
and snap securely into place.
Standard Remote Sensor (BAYSENS077)
When using the remote sensor, BAYSENS077, mount it
in the space that is to be controlled. Wire according to
the interconnecting wiring diagrams on the unit.
