IMPORTANT: Read entire instructions before programming the
thermostat.

GENERAL

The 7-day, commercial, programmable thermostats are wall-mounted, low­voltage thermostats which maintain room temperature by controlling the op­eration of an HVAC (heating, cooling and ventilation) system. Separate heat­ing and cooling set points and auto-changeover capability allow occupied
and unoccupied programming schedules for energy savings.

All thermostats allow up to 3 occupied and one unoccupied time/
temperature setting to be programmed per 24-hr period. Each thermostat stores
programs for 7 independent days. Batteries are not required. During power
interruption the internal NEVERLOST™ memory stores programs for an un­limited time.

IMPORTANT: The thermostat has a security option which can be config­ured by the installer to limit certain functions of the thermostat such as
changing set points and modifying programming schedules. If the thermo­stat does not allow modification of these functions, call the installer to per­form desired changes.

Heat or Cool Indicator — A Heat or Cool indicator is located on the bot­tom left cover of the thermostat. See Fig. 2. The light will be red if the ther­mostat is in Heating mode. The light will be green if the thermostat is in
Cooling mode.

Thermostat Front Panel Buttons — The thermostat has buttons on the
front cover which are used to raise or lower the desired set point and override
the current program. See Fig. 2.

SET POINT BUTTONS — The UP ARROW and DOWN ARROW buttons
will raise or lower the current desired temperature set point. If the thermostat
is in AUTO mode, pressing the UP ARROW or DOWN ARROW buttons
will adjust both the heating heating and cooling set points. Pressing the UP
ARROW or DOWN ARROW buttons in Cooling mode will adjust only the
cooling set points. Pressing the UP ARROW or DOWN ARROW buttons in
Heating mode will adjust only the heating set points. The UP ARROW and
DOWN ARROW buttons are also used in programming mode.

OVERRIDE BUTTON — The Override button is used to force the thermo­stat from Unoccupied mode into the Occupied 1 mode comfort settings. The
Override period will be set at 30 minutes. The thermostat will then return to
Unoccupied mode. To increase the amount of time in Override mode, press
the Override button again. Thirty minutes of override time will be added for
each time the Override button is pressed up to a maximum of 4 hours. After
the 4-hour limit has been reached, press the Override button again to cancel
Override mode.

While in Override mode, the Override icon and the Occupied 1 icon will
be displayed on the thermostat. The time of day and the minutes remaining
in Override mode will alternate on the thermostat display.

The set points are adjustable with the UP ARROW and DOWN ARROW
keys during Override mode.

NOTE: If the thermostat is in Occupied mode and the Override button is
pressed, the thermostat will go into Unoccupied mode immediately. The ther­mostat will remain in Unoccupied mode until the next Occupied start time.

Thermostat Programming Buttons — The thermostat has program­ming buttons which are used to change the set points of the thermostat, set
the modes, and program schedules. The programming buttons are accessible
from underneath the thermostat cover. To access the programming buttons,
pull on the hinged thermostat cover. See Fig. 3. The programming buttons
are: Mode, Fan, Holiday, Program, and Set Clock.

The UP ARROW and DOWN ARROW buttons are used to scroll through
programming set points. The buttons are also used to answer yes or no.

KEYPAD LOCK — The thermostat has a keypad lockout feature which will
not acknowledge front panel buttons until the lockout sequence is entered. To
disable or lock the keypad, press and hold the Mode button. While holding
down the Mode button, press the UP and DOWN ARROW buttons simul­taneously. The ‘‘Locked’’’ icon will appear on the display.

The thermostat is unlocked by performing the same procedure. Press and
hold the Mode button. While holding down the Mode button, press the Up
and Down Arrow buttons simultaneously. The ‘‘Locked’’ icon will be re­moved from the display.

FANBUTTON OPERATION — The Fan button selects fan operation. When
the fan is set to FAN ON, the fan will run continuously for improved air
circulation.

NOTE: When the thermostat is in Unoccupied mode, the fan will run only
during heating or cooling operation, even if the fan is set to FAN ON, this
is the energy-saving smart fan feature.

When the fan is not set to FANON (no icon displayed on thermostat screen),
the fan will run during heating and cooling operation only.

MODE BUTTON OPERATION — The Mode button selects the operating
mode of the thermostat. If OFF is selected, the thermostat will not enter Heat­ing or Cooling mode. If HEAT is selected, the thermostat will only enter
Heating mode (if the room temperature is below the heating set point). If
COOL is selected, the thermostat will only enter Cooling mode (if the room
temperature is above the cooling set point). If AUTO is selected, the ther­mostat will enter Heating or Cooling mode based on the room temperature
and the heating and cooling set points. If PROGRAM ON is selected, the
stored schedule is enabled and the thermostat will follow the Occupied and
Unoccupied schedules stored in its memory.

Auto-Changeover — When the thermostat mode is set to AUTO, the ther­mostat will provide automatic changeover from Heating to Cooling mode
and Cooling to Heating mode when required. The thermostat will automati­cally switch to maintain the desired temperature setting. The thermostat does
not need to be manually changed from heating to cooling or cooling to heat­ing operation.
