Notes:
–
Resistance in excess of 2.5 ohms per
conductor can cause deviations in the
accuracy of the controls.
–
Confirm the wiring between controls and
the unit 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.

Space Temperature Averaging
Space temperature averaging is accomplished by wiring a
number of remote sensors in a series/parallel circuit.
When using the BAYSENS016* or BAYSENS077*, at least
four sensors are required to accomplish space temperature
averaging.
•
Example #1 illustrates two series circuits with two
sensors in each circuit wired in parallel. The square of
any number of remote sensors is required.
•
Example #2 illustrates three sensors squared in a
series/parallel circuit. Using BAYSENS077*, two
sensors are required to accomplish space temperature
averaging.
•
Example #3 illustrates the circuit required for this
sensor. lists the temperature versus resistance
coefficient for all sensors.
