NOTE:
If installing this thermostat in a new installation, locate the thermostat
4 to 5 feet above the floor in accordance with applicable building codes. Install
the thermostat in a location that provides good airflow characteristics and avoid
areas behind doors, near corners, air vents, direct sunlight or heat generating
devices. Installation in these areas could impact thermostat performance.
Wiring must conform to all building codes and ordinances as required by local
and national code authorities having jurisdiction.
1.
Turn off power to the air conditioning or heating system prior to
installing thermostat.
2.
Place system switch on front of thermostat to
OFF
position.
3.
Place fan control switch on front of thermostat to
AUTO
position.
4.
Remove front of thermostat body from sub-base by pressing release latch.
5.
Place the thermostat sub-base against wall in the desired thermostat location.
6.
Guide thermostat wires through hole in sub-base. Continue to hold against wall.
7.
Mark placement of mounting holes as appropriate and drill using a 3/16" drill bit.
8.
Gently tap supplied plastic anchors into the holes in the wall.
9.
Place the thermostat sub-base against the wall in the desired location,
making sure the mounting holes are aligned and the thermostat wires are
inserted into the opening in sub-base.
10.
Fasten sub-base to wall using supplied screws.
11.
Connect wires to quick wiring terminal block using the new terminal
designations. See section 7.
12.
Make sure all of the wire connections are secure and not touching any other
terminal to prevent electrical shorts and potential damage to the thermostat.
13.
Turn the front thermostat body over, exposing the rear view of the
circuit board.
14.
Locate the internal
˚F /˚ C
switch on the circuit board. Using your fingers,
flip the switch toward the preferred temperature
˚F / ˚C scale
.
15.
Locate the internal fan option switch,
HG
(Gas) /
HE
(Elec) on the circuit
board. This switch controls the heating system fan delay. Select gas for gas
or oil fired systems. This will allow the furnace to run for a few seconds
before initiating the fan. Select electric for systems with electric furnace
elements that require the fan to come on immediately. Using your fingers,
flip the switch toward
HG
(Gas) or
HE
(Elec).
NOTE:
For heat pump systems, the fan option switch should be set according to
the second stage heating system type.
16.
Locate the internal
NORM / HP
switch on the circuit board. This switch
configures the thermostat for conventional (NORM) heating and cooling
systems or heat pump (HP) systems. Using your fingers, gently flip the
switch toward
NORM
or
HP
.
17.
Attach front body of thermostat to sub-base of thermostat, being careful
to align the terminal pins on the front body with the terminal block on
the sub-base.

Testing Your New Thermostat
3
• Do not short (or jumper) across terminals on the gas valve or at the heating or
cooling system control board to test the thermostat installation. This could
damage the thermostat and void the warranty.
• Do not select COOL mode if the outside temperature is below 50˚ F (10˚ C).
This could damage the controlled cooling system and cause personal injury.
• This thermostat includes an automatic compressor protection feature to
avoid potential damage to the cooling system from short cycling. This
thermostat automatically provides a 5-minute delay after turning off the
cooling or heating system output to protect the compressor.
NOTE:
Test your thermostat prior to programming any user settings. Pressing
the
RESET
button will erase any user entries previously programmed and return
them to their default values
.
1.
Place the system switch in the
HEAT
position.
2.
Press the button on the keypad until the set point temperature setting is a
minimum of 3 degrees higher than the current room temperature. The heating
system should start within several seconds. The fan may not turn on
immediately due to the heating system built-in fan delay.
3.
Place the system switch in the
OFF
position. The heating system should stop
within several seconds with conventional heating or cooling systems. On heat
pump systems you must wait 5 minutes for the automatic compressor short
cycle protection period to expire, or press the
RESET
button to bypass this
feature for initial testing purposes. Pressing the
RESET
button will erase any
user program settings.
4.
Place the system switch in the
COOL
position.
5.
Press the button on the keypad until the set point temperature is a minimum
of 3 degrees lower than the current room temperature.
6.
The cooling system should start within several seconds. Place the system
switch in the
OFF
position. The cooling system should stop within a few seconds.
7.
Place the fan switch in the
ON
position. The system blower should start.
8.
Place the fan switch in the
AUTO
position. The system blower should stop.
NOTE:
If the thermostat was powered (batteries installed) prior to accomplishing
steps 14 through 16, you will need to reset the thermostat to register thermostat
switch configurations prior to programming any user settings. Gently press
the
RESET
button on the front of the thermostat using a paperclip or a small
pencil tip.
NOTE – MODEL 1200, 1200NC:
If the thermostat is
configured for a conventional system and the system
switch is in the
EMER
position, the unit will still
function in a conventional 2 stage
HEAT
mode, but
the display will flash
NO AUX SET
.
18.
Open front thermostat door and open battery compartment door.
19.
Install two new "AA" alkaline batteries. Locate the positive (+) ends of the
batteries and match them with the positive (+) terminals located in the
battery compartment. Close battery compartment.
20.
Restore system power so you can test installation.
NOTE–MODEL 1000, 1000NC:
This thermostat is designed for use with 24
Volt-AC low voltage single stage gas, oil or electric heating or cooling systems,
including single stage heat pumps and can also be used on 250mv to 750mv
millivolt heating only systems. Do not use this thermostat on applications with
voltages above 30 Volts AC.
NOTE–MODEL 1200, 1200NC:
This thermostat is designed for use with 24
Volt-AC low voltage multi-stage gas, oil or electric heating or cooling systems,
including multi-stage heat pump systems. Do not use this thermostat on
applications with voltages above 30 Volts AC.
