INSTALLATION
Thermostat installation and all components of the
control system shall conform to Class II circuits per
the NEC code.
WARNING
!
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.
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
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.

BLUE EASY INSTALL INPUTS/OUTPUTS
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.
