INSTALLATION
• Remove security screw on bottom of Room Controller cover.
•
Open unit by pulling on bottom side of Room Controller (Figure 1).
• Remove wiring terminals from sticker.
• Read FCC ID and IC label installed in the cover.
Location
1. Should not be installed on outside wall.
2. Must be installed away from any direct heat source.
3. Should not be installed near air discharge grill.
4. Should not be affected by direct sun radiation.
5. Nothing should restrict vertical air circulation to Room Controller.
Installation
1. Swing open Room Controller PCB to left by pressing PCB locking tabs
(Figure 2).
2. Pull out cables 6” out from wall. Ensure wall surface is flat and clean.
4. Insert cable in central hole of base.
5. Align base and marklocation of two mounting holes on wall ensuring proper
side of base is up.
6. Install anchors in wall.
7. Insert screws in mounting holes on each side of base (Figure 2).
8. Gently swing back circuit board on base and push until tabs lock.
9. Strip each wire 1/4 inch from end.
10. Insert each wire according to wiring diagram (next page).
11. Gently push excess wiring back into hole (Figure 3).
12. Re-Install wiring terminals in correct locations (Figure 3).
13. Re-install cover (top side first) and gently push extra wire length back into hole
in wall.
14. Install security screw.

Figure-1 Ope ning the Cover
• If replacing an existing Line Voltage FCU Controller, label the
wires before removal of the controller.
• Electronic controls are static sensitive devices. Discharge
yourself properly before manipulating and installing the
Room Controller.
• A short circuit or wrong wiring may permanently damage the
Room Controller or the equipment.
• All SER7300 series controls are designed for use as
operating controls only and are not safety devices. These
instruments have undergone rigorous tests and verification
prior to shipping to ensure proper and reliable operation in
the field. Whenever a control failure could lead to personal
injury and/or loss of property, it becomes the responsibility
of the user / installer / electrical system designer to
incorporate safety devices ( such as relays, flow switch,
thermal protections, etc…) and/or an alarm system to
protect the entire system against such catastrophic failures.
Tampering with the devices or unintended application of the
devices will result in a void of warranty.

COMMUNICATION WIRING TO SC3XXXX RELAY PACK
Only ONE SC3xxxX Relay Pack with remote
monitoring inputs can be used under a single
SER73xxA Controller. All other slave units must be
SC3xxxX Relay Pack(s) WITHOUT remote inputs. A
maximum of 10 SC3xxxX Relay Packs can be used
for a single SER73xxA Room Controller.
From the SER73xxA to the first SC3xxxX
Relay Pack
• Uses existing or new field wires
• A minimum of 3 wires are required 14-22 Ga Solid
or Stranded. Shield not necessary.
From the first SC3xxxX to all other slave
SC3xxxX Relay Pack(s)
• Uses existing or new field wires
• A minimum of 2 wires are required 14-22 Ga Solid
or Stranded.
Shield not necessary.
• Connect only wires #1 Power Common and #2
