INSTALLATION GUIDE

NEEDED MATERIAL

•
Screw Driver: A #2 Phillips is required to connect the
cables to the terminals.
• Mounting: Mounting brackets are included. Mounting
hole fits #10 screw
• Conduit: To maintain the IP rating of the unit, it must
be installed with ½" cable glands or with weather-proof
½" conduit fittings at the power/signal entry points.

INSTALLATION INSTRUCTIONS

1. Select a suitable installation location for the Control-
485 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-485 using the brackets included.
(See last page of this install guide for mounting
template).
4. Open the enclosure cover.
5. Install cable glands or conduit fitting as required.
6. For 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
7. For DC Powered: Connect the DC power supply wire
(+) to 24VAC/VDC and (-) to COMMON. See Figure
3.
8. If the Control-485 is being connected inline with the
BACnet thermostat, connect the thermostat power
wires to the same Control-485 terminals COM/GND
and 24VAC/DC. See Figure 2
9. RS-485/BACnet serial connections: Connect the
Control-485 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.
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.
10. RS-422 serial connections: For serially controlled
11. Ensure all control lines are reattached to the
12. Contact Synapse for Support- (877) 982-7888
devices using the RS-422 standard, connect the
Control-485 screw terminal RD- to the controlled
device terminal TD-, RD+ to TD+, TD+ to RD+, TD-
to RD- and GND to GND respectively. See Figure 5.
