Wiring
Match your transmitter with the corresponding diagrams
(Figure 4 through Figure 9), set the switches and wire
accordingly. (See Figure 3 below for switch and terminal
block locations.) Ensure that all the installation and wiring is
in compliance with all national and local codes.
Note: All Voltage Outputs are measured with respect to the
POWER SUPPLY / CONTROLLER GROUND.
Wiring for the transmitter should be a shielded, twisted pair,
16-22 AWG. Use only copper conductors. Do not run
transmitter wires and AC power wires together in the same
conduit or wire bundle.
Caution!
Running transmitter wires and AC power wires,
including earth ground, in the same conduit or
wire bundle may cause malfunction due to
electrical noise.

CE COMPLIANCE
Ensure that the probe earth ground wire (for Duct and
1.
Outside Air units only), the shield wire and the PCB earth
ground wire are connected to the mounting screw or the
NEAREST (<1.5m) earth ground.
The other end of the shield wire MUST be connected to
2.
the power supply /controller earth ground ONLY.
Hold the sides of
the sensor tip
near the base of
the sintered filter.
Caution: Remove power before replacing the sensor.
