DANGER
READ THESE INSTRUCTIONS CAREFULLY BEFORE ATTEMPTING
TO INSTALL, OPERATE OR SERVICE THIS THERMOSTAT.
Failure to observe safety information and comply with instructions
could result in PERSONAL INJURY, DEATH AND/ OR PROPERTY
DAMAGE.
To avoid electrical shock or damage to equipment, disconnect power
before installing or servicing. Use only wiring with insulation rated for
full thermostat operating voltage. Use copper wire only. Insulate or
wire-nut all un-used leads. Any wiring, including the remote probe, may
carry the full operating voltage of the thermostat.
To avoid potential fire and/ or explosion do not use in potentially
flammable or explosive atmospheres.
Retain these instructions for future reference. You must review your
application and national and local codes to ensure that your installation
will be functional and safe.
CAUTION
Care should be used to avoid electrostatic discharge to the
microprocessor.
This unit has configuration dip switches and jumpers. You may need to
reconfigure the thermostat for your application.
1. Install the thermostat with the two furnished mounting
screws to a standard 4-1/16" × 2-1/8" square device
box with a 2" × 4" adapter ring.
2. For wall installations, mount the thermostat on an
inside wall approximately 5 feet above the floor. The
location should provide circulation at average room
temperature. Avoid direct sunlight or sources of hot or
cold air in the room or wall.
3. Remove the cover. Mount thermostat base assembly
to the outlet box using screws provided. Tighten the
screws evenly but do not overtighten. Connect wires
per wiring diagram.
4. To use a remote sensor on units with local sensing
capability, remove jumper JP-1 to disable local
sensing. Failure to remove JP-1 will cause improper
operation of thermostat.
5. Connecting a jumper between terminals 16 and 17
will disable the secondary output and change the
main output to heat mode.
6. Connection of a 24 VAC set-back signal will force
the control into unoccupied mode (see diagram).
Pressing an arrow key or the mode buttons on the
thermostat cover will disable the setback input for
one hour.
7. Remove the LCD plastic protective film to complete
the installation. Reinstall the cover assembly. Install
cover locking screw provided.
8. Checkout: After wiring and installation are complete,
energize the system and check the operation. Adjust
the thermostat as necessary to complete at least one
cycle. Be sure the thermostat and all other equipment
are functioning correctly.
