INSTALLATION
!WARNING
Thermostat installation and all components of the control system shall conform to Class II circuits per the NEC code.
Control 40C01-1400
Control can be mounted on wall or equipment. Control has four mounting holes. Wall anchors and screws are provided for mounting on drywall. Drill 3/16 hole for drywall mounting.
If mounting on equipment Do Not Mount inside HVAC equipment. Only mount on outside of HVAC equipment.
Thermostat / Interface 1F98-1491
1)Pull the thermostat/interface off the base. Forcing or prying on the thermostat will cause damage to the unit.
2)Place base over hole in wall and mark mounting hole locations on wall using base as a template.
3)Move base out of the way. Drill mounting holes. If you are using existing mounting holes and the holes drilled are too large and do not allow you to tighten base snugly, use plastic screw anchors to secure the base.
4)Fasten base snugly to wall using mounting holes and two mounting screws. Leveling is for appearance only and will not affect thermostat operation.
5)Connect wires to terminal block on base (see Figure 1).
6)Push excess wire into wall and plug hole with a fire resistant material (such as fiberglass insulation) to prevent drafts from affecting thermostat operation.
7)Carefully line the thermostat up with the base and snap into place.
WIRING CONNECTIONS
Refer to equipment manufacturers’ instructions for specific system wiring information. After wiring, see CONFIGURATION section for proper thermostat configuration.
Connect wires as appropriate for HVAC systems (see wiring diagrams). To power control, connect the 24 V system hot to R terminal and common to C on left side of control labelled “Power”. On initial power up the 7 segment LED on the
control will display E (for communication error) until interface is connected. With power supplied to control, it is normal for the green system LED to flash periodically.
With interface connected, the 7 segment LED will display C to indicate the two devices have initiated communication. C will disappear after approximately 30 seconds when communication is established.
