INSTALLATION GUIDE

INCLUDED MATERIAL

• 2 Cable glands
• 1 Hole plug
• Mounting brackets

NEEDED MATERIAL

•
Screw Driver: A #2 Phillips is required to connect the
cables to the terminals.
• Mounting Screws: Mounting bracket holes fit #10
screws
• Conduit: To maintain the 4X rating of the enclosure, it
must be installed with the 4X ½" cable glands supplied
or with minimum 4X liquid-tight ½" conduit fittings, not
supplied, at the power/signal entry points.

INSTALLATION INSTRUCTIONS

1. Select a suitable installation location for the Control
Thermostat hardware e.g. between the BACnet
thermostat and the HVAC/MAU.
2. Select between inline or adjacent installation, see
Figure 1 for more details.
3. Mount the Control Thermostat hardware using the
brackets included.
4. Open the enclosure cover.
5. Install ½" cable gland(s) supplied and torque nuts to
60 in-lbs; or use liquid-tight conduit fittings as
required.
6. If only one cable entry is used, plug the unused hole
with the liquid-tight plug supplied.
7. To maintain the IP rating, jacketed cable wires are
recommended with cable diameter of 0.21" – 0.33".
Torque sealing cable glands to 40-55 in-lbs,
depending on the cable diameter and jacket
hardness.
8. AC powered: Connect the AC power wires (e.g. from
the HVAC 24VAC transformer) to wire terminals
COMMON and 24VAC/DC maintaining the correct
polarity. See Figure 2
WARNINGS AND CAUTIONS:
• If you are unsure about any part of these instructions, consult an electrician.
• Use this device with copper or copper clad wire only.
Mounting: For best RF performance and signal strength, do not mount this device
inside a metal box. Final installed unit should also be mounted with open space on 2 or
more sides.
