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 the central hole of the base. 5. Align base and mark location 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. 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. • When replacing an existing Room Controller, label the wires before removal of the Room Controller. • Electronic controls are static sensitive devices. Discharge yourself properly before manipulating and installing the Room Controller. • A short circuit or improper wiring may permanently damage the Room Controller or the equipment. • All SEZ7000 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 or installer or 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.

There is a low backlight level that is always active and can only be seen at night. When left unattended, the Room Controller has an auto scrolling display that shows the current status of the system. Each item is scrolled sequentially with the back light in low level mode. Pressing any key will cause the back light to come on to high level. Manual scrolling of each menu item is achieved by pressing the Yes (scroll) key repetitively. The last item viewed will be shown on the display for 30 seconds before returning to automatic scrolling. Temperature is automatically updated when scrolling is held. Sequence of auto-scroll status display: ROOM TEMPERATURE OCCUPANCY STATUS OUTDOOR TEMPERATURE RoomTemp x.x °C or°F OccupiedOutdoor x.x °C or°F Stand-By Unoccup Override Outdoor air temperature • Outdoor air temperature display is only enabled when outdoor air temperature sensor is connected. • A maximum range status display of 50 °C ( 122 °F ) indicates a shorted sensor. Associated functions, such as mode lockouts and economizer function are automatically disabled. • A minimum range status -40 °C ( -40 °F ) is not displayed and indicates a opened sensor or a sensor not connected. Associated functions, such as mode lockouts and economizer function are automatically disabled. Occupancy Status • Occupied, Stand-By, Unoccupied and Override status are displayed on the scrolling display. • Two status LED’s on the controller cover are used to indicate a call for heat or a call for cooling When heating and reheat is ON, the HEAT LED will illuminate. When cooling is ON, the COOL LED will illuminate.Next >
