Reset Operation
If a voltage spike or static discharge blanks out the display or
causes erratic thermostat operation you can reset the thermo-

stat by pressing

and move the SYSTEM switch from

OFF to HEAT at the same time. This also resets the factory
defaults to the configuration menu. If the thermostat has
power, has been reset and still does not function correctly
contact your heating/cooling service person or place of pur-
chase.

Batteries
For optimum performance, we recommend replacing batteries
once a year with fresh "AA" Energizer

alkaline batteries.

TROUBLESHOOTING

2) Select FA or SL (Fast or Slow) Heating Cycle Rate - The

FA setting is frequently used for gas, oil or electric heat. The
SL setting produces a longer heating cycle which is nor-
mally for hot water or steam (hydronic) systems. Both
settings produce very accurate temperature control and
can be set to your personal preference. FA cycles the
system just under 1°F and the SL setting cycles at approxi-
mately 1.5°F.

3) Select Display Backlight (d-L OFF or ON) - The display

backlight improves display contrast in low lighting condi-
tions. Selecting backlight ON will keep the light on for a
short period of time after any key is pressed. Selecting OFF
will keep the light off.

4) Select filter replacement run time - The thermostat will

display FILTER after the selected time of operation. This is
a reminder to change or clean your air filter. This time can
be set from 0 to 1950 hours in 50 hour increments. A
selection of 000 will cancel this feature. When FIL-
TER is displayed, you can clear it by pressing

and

at the same time. This resets the timer and starts

counting the hours until the next filter change.

5) Select Compressor Lockout (LOC OFF or ON) - Select-

ing LOC ON will cause the thermostat to wait 5 minutes
before turning on the compressor if the heating and cooling
system loses power. It will also wait 5 minutes minimum
between cooling cycles. This is intended to help protect the
compressor from short cycling. Some newer compressors
already have a time delay built in and do not require this
feature. Your compressor manufacturer can tell you if the
feature is already present in their system. When the
compressor time delay occurs it will flash the (snowflake
icon) for about five minutes then turn on the compressor.

6) Select Temperature Display Adjustment (4 LO to 4 HI)

- Allows you to adjust the room temperature display 4°
higher or lower. Your thermostat was accurately calibrated
at the factory but you have the option to change the display
temperature to match your previous thermostat.

7) Select Temperature DIsplay (°F or °C) - Changes the

display readout to Celsius or Fahrenheit as required.

8) Select Stage Fast (ON or OFF) - When selected ON, the

second stage starts as soon as the setpoint temperature is
manually raised 3°F in heat or lowered 3°F in cool from
room temperature. When selected OFF, the second stage
will delay approximately 15 minutes before starting.

OPERATING FEATURES

Now that you are familiar with the thermostat buttons and
display, read the following information to learn about the many
features of the thermostat.

• SIMULTANEOUS HEATING/COOLING SETPOINT

STORAGE — You can enter both your heating and cooling
setpoints at the same time. There is no need to change the
thermostat at the beginning of each season.

• CONFIGURATION MENU — Allows you to customize

certain thermostat options.

SETTING THE THERMOSTAT

This thermostat is very easy to operate. Set the SYSTEM switch

to either HEAT or COOL then press

until the

temperature you want to maintain is shown on the right side of
the display. If you want to turn the system off, just move the
SYSTEM switch to OFF.

The FAN switch controls the fan operation. When the FAN
switch is set to AUTO, the fan will cycle with the furnace or air
conditioner. When the FAN switch is set to ON, the fan will run
continuously, regardless of SYSTEM switch position.
