Connecting the Probes
The controller is supplied with one temperature probe connected to input
# 1. Up to three additional probes can be connected to the controller in order
to obtain a more accurate reading of the average room temperature and a
faster reaction time.
n
Use inputs # 2, 3 and 4 to connect additional probes, as shown on the
wiring diagram enclosed.
CAUTION
:
Probes operate at low voltage and are isolated from the supply.
Be sure that probe cables remain isolated from all high voltage sources. In
particular, do not route the probe cables through the same electrical knockout
as other cables. Do not connect the shield from the probe cable to a terminal
or a ground.
Switches are used to activate or deactivate the additional probes connected
to the controller.
n
Activate each additional probe by setting
the appropriate switch to
ON
:
• Switch # 3 activates the probe connected to input # 2.
• Switch # 4 activates the probe connected to input # 3.
• Switch # 5 activates the probe connected to input # 4.
