INSTALLATION
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.
Preparation
• 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 cover,
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 flat and clean).
3. Insert cable in central hole of base.
4. Align base and mark location of two mounting holes on wall.
(ensure proper side of base up).
5. Install anchors in wall.
6. Insert screws in mounting holes on each side of base (Figure 2).
7. Gently swing back circuit board on base and push until tabs lock.
8. Strip each wire 1/4 inch from end.
9. Insert each wire according to wiring chart (page 3).
10. Gently push excess wiring back into hole (Figure 3).
11. Re-Install wiring terminals in correct locations (Figure 3).
12. Re-install cover (top side first) and gently push extra wire length back into
hole in wall.
13. Install security screw.
• If replacing an existing Room Controller, label wires before
removal of Room Controller.
• Electronic controls are static sensitive devices. Discharge
yourself properly before manipulating and installing Room
Controller.
• A short circuit or wrong wiring may permanently damage the
Room Controller or the equipment.
• All SE7000 series Room Controllers 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) 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.

MAIN OUTPUTS WIRING
Wiring notes:
Note 1: If the same power source is used for the heating stages, install jumper across RC and RH. Maximum current is 2.0 amps.
Note 2: If auxiliary output is used to toggle occupancy of the electronic control card inside the equipment, configure the relay
parameter (Aux cont) to the N.O. setting. A second relay can be added for additional functionality of the occupancy
output.
Note 3: Humidifier output uses a half bridge rectifier. Reference of the control signal is the common of the power supply of the
Room Controller. (Terminal C)
Note 4: Electromechanical contacts are to be used with the digital inputs. Electronic triacs cannot be used as mean of switching
for the input. The switched leg to the input for the input to activate is terminal C (common)
Note 5: The transformer of the unit provides power to the Room Controller and the additional loads wired to the Room Controller.
