10. Connect red wire of the pigtail to V+ RED terminal. Con-

nect black wire of the pigtail to Vg BLACK terminal.

NOTE: The 2-wire pigtail is not intended to support the weight

of the display module. Do not hang the user interface from the

equipment control module screw terminals.

11. Seal hole in wall to prevent air leaks. Leaks can affect oper-

ation and cause incorrect temperature and/or humidity

measurement.

12. Attach 2-wire pigtail to display module. Pigtail is packed

loose in the box from the factory. Pigtail is attached to the

back of the display module via 2-pin, keyed connector.

13. Reattach display module body to mounting base by first

setting the module on at top of mounting base and then

snapping the bottom corners of display module into place.

See Fig. 7.

14. Find a suitable indoor mounting location for equipment

control module. The module should be mounted on or near

the HVAC equipment. See Fig. 8.

15. Route wires through rear of equipment control module us-

ing either a clearance hole or supplied standoff. See Fig. 9.

Standoff is provided as an aid when installing equipment

control module on equipment or a solid wall.

NOTE: The equipment control module should 

not

 be

mounted to ductwork or below any other controls or equip-

ment (i.e., humidistat, humidifier, etc.).

16. 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 connect-

ing the two wires from the equipment control module to the

display module

mounting base. If wires are connected in-

correctly, the display module will not operate. See Fig. 10.

17. Snap cover over top of equipment control module. See

Fig. 11.

18. Turn on power to equipment. On power up, all display seg-

ments will light for 5 seconds. For the next 5 seconds, a 2-

digit code will appear on the center of the large display

which identifies the equipment configuration:

AC — Two-stage heat / Two-stage cool
HP — Three-stage heat / Two-stage cool
