WIRED THERMOSTAT
Installation and Start-up
Instructions
NOTE: Read all instructions before starting the installation.
SAFETY CONSIDERATIONS
Improper wiring or installation may damage thermostat. Wiring must
conform to local and national electrical codes.
INTRODUCTION
The thermostat is a wall mounted, low-voltage thermostat which maintains
room temperature by controlling the operation of a heating and fan system.
Batteries are not required; temperature and mode settings are preserved with
the power off.
INSTALLATION
I. THERMOSTAT LOCATION
Thermostat should be mounted:
- Approximately 5 ft. (1.5m) from floor.
- Close to or in a frequently used room, preferably on an inside
partitioning wall.
- On a section of wall without pipes or duct work.
Thermostat should NOT be mounted:
- Close to a window, on an outside wall, or next to a door leading
to the outside.
- Exposed to direct light and heat from a lamp, sun, fireplace, or
other temperature-radiating object which may cause a false
reading.
- Close to or in direct airflow from supply registers and return-air
grilles.
- In areas with poor air circulation, such as behind a door or in an
alcove.
II. INSTALL THERMOSTAT
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 the wall.
C. As each wire is disconnected, record wire color and terminal
marking.
D. Discard or recycle old thermostat.
3. Separate the front and back pieces of plastic.
4. Route thermostat wires through hole in back piece of plastic. Level
plastic against wall (for aesthetic value only - thermostat need not be leveled
for proper operation) and mark wall through 2 mounting holes.
5. Drill two 3/16-in. mounting holes in wall where marked. (Note:
Mounting holes on thermostat are designed to fit on a horizontal J-box).
6. Secure back plastic to wall with 2 anchors and screws provided making
sure all wires extend through hole in plastic.
7. Connect wires to proper terminal of the connector block in the front
piece of plastic.
8. Push any excess wire back into wall. Excess wire inside the thermostat
plastic case can interfere with proper air flow across the temperature sensor.
Seal hole in wall to prevent air leaks. Leaks can affect operation.
9. Snap front and back pieces of plastic together.
10. Turn on power to the unit.
III. SET THERMOSTAT CONFIGURATION
While in configuration mode, four option choices can be made:
A = Anticipator Value Adjustment
d = Fahrenheit/Celsius Selection
Fn = G (Fan) ON with W (Heat) Selection
oF = Room Temperature Offset Adjust
An explanation for each of these and how to enter the configuration mode
follows.
TO ENTER THE CONFIGURATION MODE:
Press and hold the FAN button for approximately 10 sec until room
temperature disappears and the display reads “A“. You are now in the
configuration mode.
NOTE: If the FAN button is pressed again or if no button is pressed for 2
minutes, the thermostat will exit the configuration mode and return to
normal operation. To re-
enter the configuration mode, the FAN button must
be pressed and held for 10 sec. again.
WHILE IN CONFIGURATION MODE, THE FOLLOWING OPTIONS
ARE AVAILABLE:
A = ANTICIPATOR - Value Adjustment
This adjustment controls the sensitivity and cycle rate of the thermostat.
Higher numbers decrease the sensitivity and slow the cycle rate. Lower
numbers increase the sensitivity and increase cycle rate. However, a
limiting feature will not allow more than 4 equipment cycles per hour,
regardless of setting. Values can range from 1 to 3. Factory default setting
is 2. This default selection will provide optimum performance in nearly all
installations. Try it first. Do not change setting unless there is evidence of
need to do so. Unlike conventional anticipators, this setting is not to be
determined by current draw. There is no need to measure, know, or
compensate for current.
TO ADJUST:
1. Enter configuration mode (if not already there).
2. Use UP and DOWN buttons to display A
3. Press MODE button once to display current value.
4. Use UP and DOWN buttons to move between values.
5. Press MODE button to return to A. UP and DOWN
buttons now move between option choices 1-, 2-, etc. or
press FAN button to exit configuration mode.
d = FAHRENHEIT/CELSIUS Selection
This selection operates the thermostat in either Fahrenheit or Celsius.
TO SELECT:
1. Enter configuration mode (if not already there).
2. Use UP and DOWN buttons to display “d”
3. Press MODE button once to display current selection of F or C.
4. Use UP and DOWN buttons to change between F and C.
5. Press MODE button to return to “d”. UP and DOWN buttons now
move between option choices ; or press FAN button to exit
configuration mode.
Fn = G (FAN) ON WITH W (HEAT) Selection
This selection determines whether the G (fan) output is to be ON or OFF
when the W (furnace or strip heat) output is ON. Most furnaces and fan
coils manage their own blowers and do not require a separate G signal. For
these applications, select OFF. Some auxiliary heaters require a separate G
signal to turn on the blower. In this case, select ON. The factory default is
ON.
TO SELECT:
1. Enter configuration mode (if not already there).
2. Use UP and DOWN buttons to display “Fn”
3.
Press MODE button once to display current selection of ON or OFF.
4. Use up and down buttons to change between ON and OFF.
5.
Press MODE button to return to “Fn”. UP and DOWN buttons now
move between option choices; or press FAN button to exit
configuration mode.
WARNING: Before installing thermostat, turn off all power to unit. There
may be more than one power disconnect. Electrical shock can cause personal
injury or death.
