INSTALLATION
Step 1 — Thermostat Location
Thermostat should be mounted:
S
Approximately 5 ft (1.5m) from floor.
S
Close to or in a frequently used room, preferably on an inside
partitioning wall.
S
On a section of wall without pipes or duct work.
Thermostat should NOT be mounted:
S
Close to a window, on an outside wall, or next to a door leading
to the outside.
S
Exposed to direct light and heat from the sun, a lamp, fireplace,
or other heat--radiating object which may cause a false reading.
S
Close to or in direct airflow from supply registers and return--air
grilles.
S
In areas with poor air circulation, such as behind a door or in an
alcove.
Step 2 — Install Thermostat
IMPORTANT
: Install batteries last to ensure proper thermostat
mounting and latch engagement.
ELECTRICAL SHOCK HAZARD
Failure to follow this warning could result in personal injury
or death.
Before installing thermostat, turn off all power to unit. There
may be more than one disconnect.
!
WARNING
1. Turn OFF all power to unit.
2. If an existing thermostat is being replaced:
a. Remove existing thermostat from wall.
b. Disconnect wires from existing thermostat, one at a
time. Be careful not to allow wires to fall back into wall.
c. As each wire is disconnected, record wire color and
terminal marking.
d. Discard or recycle old thermostat.
ENVIRONMENTAL HAZARD
Failure to follow this caution may result in environmental
damage.
Mercury is a hazardous waste. Federal regulations require that
mercury be disposed of properly.
CAUTION
!
3. Separate front and back (mounting base) assembly of ther-
mostat.
4. Route thermostat wires through hole in mounting base.
Level mounting base against wall (for aesthetic value and
optimum air flow, the thermostat need not be level for prop-
er operation) and mark wall through 2 of the available
mounting holes.
5. Drill two 3/16--in. (5 mm) mounting holes in wall where
marked.
6. Secure mounting base to wall with 2 anchors and screws
provided, making sure all wires extend through hole in
plastic.
NOTE
:
Anchoring the mounting base will ensure proper
mounting and allow latch to fully engage.
7. Strip 1/4 in. insulation from thermostat wire and adjust
length to reach terminal block connector on mounting base.
Match and connect wires to proper terminal location in ac-
cordance with wiring diagrams.
8. Push any excess wire back into wall. Seal hole in wall to
prevent air leaks. Leaks can affect thermostat operation.
Any excess wire left inside thermostat casing may also af-
fect thermostat operation by interfering with airflow across
the temperature sensor.
9. Locate jumper marked J2 on circuit board. If common (C)
wire has been connected, put J2 in the ”24VAC” position. If
no common wire leave J2 in the default ”BATT” position.
10. Set the thermostat front housing into the (2) notches on the
bottom of the mounting plate.
11. Rotate the front housing forward and snap into place, mak-
ing sure terminal block connector aligns and assembly is se-
cure.
12. Remove the branded faceplate and insert batteries provided.
13. Replace branded faceplate.
14. Turn ON power to unit.
On power up, the LCD readout will display AC, as this is the
default equipment type.
Step 3 — Set Thermostat Configuration
Configuration options allow the installer to configure the
thermostat for a particular installation.
These selections are intended to be made at installation and
normally are not modified by the homeowner. Below is a list of
available options followed by a description of each one.
Option 01 -- Equipment type
Option 03 -- Fahrenheit/Centigrade operation
Option 04 -- Enable fan (G) on with heat W output
Option 10 --O (reversing valve) On with Heat or cool (present
only when configured for HP applications)
Option 13 -- Room air temperature offset adjustment
Option 15 --Auto Changeover. “OF” means AUTO Mode is off.
“ON” means AUTO MODE is on. Default = OF.
To Enter The Configuration Mode:
Press and hold FAN button for approximately 10 sec until room
temperature disappears and the display reads “01”. You are now in
configuration mode.
NOTE
: If FAN button is pressed again, or if no button is pressed
for 3 minutes, the thermostat will exit configuration mode and
return to normal operation. To re--enter configuration mode, the
FAN button must be pressed and held for 10 sec again.
While in the configuration mode, the temperature display is used to
show both the option number and the selected choice within each
option. Each press of the MODE button alternates between the
option number and the selection within that option. When the
configuration mode is first entered, option 01 is displayed. The UP
and DOWN buttons now move between the available option
numbers. Once an option number is selected, press the MODE
button once to display the currently selected choice within that
option. The UP and DOWN buttons now move between the
available choices within that option. After the new choice is made,
press the MODE button again to return to the option number
display. When finished with option selections, press FAN button
once to exit the configuration mode.
