2.5 TEMPERATURE PROBES
Temperature probes use a “Class 2” low voltage circuit.
These cables can measure up to 500 feet (150 meters).
Probes longer than 10 feet (3 meters) must be shielded
with a #18AWG aluminum wire, or one bigger. The
shield must be connected to the CPS-3M’s SHLD
terminal.
The connections for 2 temperature probes are illustrated in
figure 2, whereas the connections for temperature
averaging are illustrated in figure 3.
2.5.1 2 Temperature probes
Install the temperature probes in the area that best reflects
the overall room temperature.
Connect both temperature probe leads and the shield to
the terminals labelled IN1 and IN2 (see figure 2).
2.5.2 Temperature averaging
•
1 Zone : Four temperature probes are required to
perform temperature averaging in larger rooms
•
2 Zones : Eight temperature probes are requiredto
perform temperature averaging in two rooms (4 per
zone)
To get superior readings, place the probes in locations that
best reflect room temperature (see figure 3).
