Note:
Ensure that the wiring between controls and the
unit’s termination point does not exceed two and a
half (2.5) ohms/conductor for the length of the run.
•
Do not run the electrical wires transporting DC signals
in or around conduit housing high voltage wires.
•
Route low voltage wiring per

Space Temperature Averaging
(ReliaTel™ Only)
Space temperature averaging is accomplished by wiring a
number of remote sensors in a series/parallel circuit.
Using the BAYSENS016* or BAYSENS077*, at least four
sensors are required to accomplish space temperature
averaging. See diagram below.
