Space Temperature Averaging - Trane TH 150-300 Series Installation, Operation And Maintenance Manual

Space Temperature Averaging

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.
Example #1 illustrates two series circuits with two sensors
in each circuit wired in parallel. The square of any number
of remote sensors required. Example #2 illustrates three
sensors squared in a series/parallel circuit. Example #3
illustrates the circuit required for this senor.
the temperature versus resistance coefficient for all
sensing.
