CAUTION
•
The Control Thermostat hardware must be installed in
accordance with national, state, and local electrical codes
and requirements.
•
All work must be performed by qualified personnel.
• The common signal
from the Control Thermostat
hardware
should not be tied to earth ground.
•
Disconnect all power before installation or service.
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
9.
DC Powered: Connect the DC power supply wire (+)
to 24VAC/VDC and (-) to COMMON.
See Figure 3.
10.
If the Control Thermostat hardware is being
connected inline with the BACnet thermostat,
connect the thermostat power wires to the same
Control Thermostat hardware terminals COM/GND
and 24VAC/DC. See Figure 2
11.
RS-485/BACnet serial connections: Connect the
Control Thermostat screw terminal D+ to MS/TP+ on
the BACnet thermostat, D- to MS/TP- and GND to GND
;or connect to D+ to D+, D- to D- and GND to GND on
any other RS-485 serially controlled devices.
See Figure 4.
12.
Ensure all control lines are reattached to the
thermostat.
