1. SELECT THE THERMOSTAT LOCATION

To ensure accurate temperature control, mount the thermostat

on an inside wall in a frequently occupied space that best represents the building temperature. Mount the thermostat at least 18" from any outside wall and approximately 5 ft. above the floor.

DO NOT locate the thermostat: .behind doors, in corners or other dead air spaces

.in direct sunlight or near lamps, appliances or other sources

of radiant heat

.on an outside wall or a wall exposed to an unconditioned

space (e.g., garage, etc.)

.in the flow path of a supply register, in stairways or near

outside doors

.on a wall where concealed pipes and/or ductwork will

affect the thermostat

.near sources of electrical interference such as arcing relay

contacts

2. UNLATCH THE THERMOSTAT PANEL FROM THE BASE

3. MOUNT THE BASE TO THE WALL

a. Place the base over the wire hole opening in the wall; level

the base and mark the mounting locations (leveling is

required for appearance only -

MAR<OUTUNE

see Figure 4). b. If using supplied

wall anchors, drill a 3/16" hole in the center of the marked

locations and tap in

~ cO the wall anchors. If

~~~:!::I~. using supplied

screws only, drill a

3/32" hole in the center of the marked locations.

c. Fasten the base to the wall with the supplied screws.

4. WIRE THE THERMOSTAT AND SET DIP SWITCHES

a. Set the DIP switches located on the thermostat circuit board

according to the application needs. Figure lIon the back

of this sheet defines all the DIP switches. b. Strip 1/4" of insulation from each wire to be used. c. Secure wires into the terminals on the base according to the

appropriate wiring diagram shown on the back (see Figures

8-10). Use color coding practices (e.g., white wire to W terminal) whenever possible.

d. Check each wire to ensure it is securely fastened, not

broken, and no exposed wires are touching.

a. Push each wire flush against the base to ensure proper fit

with the thennostat panel.

b. Seal the wall opening with putty or caulk to prevent drafts

from affecting the accuracy of the thennostat.

c. Place the cover on the base and swing fully open. Cover

will stay in place.

d. Install the clear plastic thennostat latch if desired (see

Figure S). The latch does not lock the cover; it is intended

(see Figure 2).

d. After the latch releases, grip the thermostat

panel at the bottom corners and swing it up and away from the base to completely separate

(see Figure 3).

Set aside the thermostat panel and cover to avoid

damage during the remainder of the installation.
