1. Remove mounting plate from back of Display Module by pressing the two tabs on the bottom edge and pulling away. See Fig. 4 and 5. A07225 Fig. 4 . Press Tabs to Remove Backplate 10 A07226 Fig. 5 . Take Apart 2. Route wires through large hole in mounting base. Level mounting base against wall (for aesthetic value only—Display Module need not be leveled for proper operation) and mark wall through 4 mounting holes. To avoid unintended bending of wall plate plastic, use all 4 screws and anchors. See Fig. 6. 11 A07165 Fig. 6 . Backplate Mounting 3. Drill two 3/16.in. mounting holes in wall where marked. Thermostat may be mounted to a standard junction box, if desired. Hole pattern on thermostat mounting base matches junction box mounting holes. 4. Secure rear plastic mounting base to wall with 4 screws and anchors provided. To avoid unintended bending of wall plate plastic, use all 4 screws and anchors Make sure all wires extend through hole in mounting base. 5. Adjust length and routing of each wire to reach proper connector block and terminal on mounting base with 1/4.in. (6mm) extra wire. 6. Match and connect equipment wires to proper terminals of each connector block being careful not to over tighten the screws. Correct polarity must be observed when connecting the two wires from the Equipment Control Module to the thermostat mounting base. If wires are connected incorrectly, the Display Module will not operate.

Do not hang the User Interface from the equipment Control Module screw terminals. . Red is V+ . Black is Vg 7. Push any excess wire into wall and against mounting base. Seal hole in wall to prevent air leaks. Leaks can affect operation and cause incorrect temperature and/or humidity measurement. 8. Make sure to attach 2.wire pigtail to Display Module mounting base. It is packed loose in the box from the factory. Then attach 2.wire pigtail to the back of the Display Module via 2 pin, keyed connector. 9. Reattach Display Module body to mounting base by first setting on at top of mounting base and then push bottom corners of Display Module to snap into place. See Fig. 10. A07169 Fig. 10 . Attach Display to Backplate 15 10. Find suitable indoor mounting location for Equipment Control Module, either near or on equipment. See Fig. 11. IMPORTANT NOTE: Equipment Control Module should not be mounted to duct work or below any other controls or equipment (i.e. humidistat, humidifier, etc.). A07217 Fig. 11 . Equipment Control Module on Equipment 11. Route wires through rear of Equipment Control Module using either a clearance hole or supplied standoff. See Fig. 12. 16 A07227 Fig. 12 . Standoff NOTE: Standoffs are provided as an aid when installing Equipment Control Module on inside equipment or a solid wall. 12. Match and connect equipment wires to proper terminals of each connector block being careful not to over tighten the screws. Correct polarity must be observed when connecting the two wires from the Equipment Control Module to the thermostat mounting base. If wires are connected incorrectly, the Display Module will not operate. See Fig. 7, 8 and 9. 13. Snap cover over top of Equipment Control Module. See Fig. 13. 17 A07218 Fig. 13 . Cover on Equipment Control Module 14. Turn on power to equipment. On power up, all display segments will light for 5 sec. For the next 5 sec a 2.digit code appears on large display which identifies AC/HP Control configuration. Refer to Option 33. a.AC —1.stage air conditioner, AC, with furnace or fan coil b.HP —1.stage heat pump, HP only with fan coil c. H — heating only system, furnace only or fan coil with electric heat only d. C — cooling only system, AC with fan coil e.H2 —2.stage heat pump with fan coil f.A2 —2.stage air conditioner with fan coil or furnace 18 Single.Piece Installation The following steps should be followed for the installation of the single.piece configuration. 1.
