2.3 Wiring Connections

For wiring details of RS-485 via communication BACnet, Modbus and Sylk
through plant or unitary controller refer hard copy of the latest Mounting
Instructions (31-00566M-02).

b
As a rule of thumb, single twisted pair (2 wires per cable only), thicker gauge, non-
shielded cable yields best results for longer runs.
c The 30 m distance for standard thermostat wire is conservative, but meant to
reduce the impact of any sources of electrical noise (including but no limited
VFDs, electronic ballasts, etc). Shielded cable recommended only if there is a
need to reduce the effect of electrical noise.
d
These distances also apply for shielded twisted pair.

2.2 Power Up the Sensor Device

Once the TR50 IAQ Sensor device is installed and powered, the device gets started
and shows firmware version number "x.x.x.x" as per the latest updated firmware
and the parameter values are displayed on the LCD.
