IMPORTANT: Read entire instructions before programming the

thermostat.

GENERAL

The 7-day, commercial, programmable thermostats are wall-mounted, low-

voltage thermostats which maintain room temperature by controlling the op-

eration of an HVAC (heating, cooling and ventilation) system. Separate heat-

ing 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-hour 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.

A light sensor is provided on the thermostat for light activation. When the

sensor detects light (the space is occupied), the thermostat will enter into

Occupied 1 mode. If the room is dark, the thermostat will follow its pro-

grammed schedule.

IMPORTANT: The thermostat has a security option which can be conﬁg-

ured by the installer to limit certain functions of the thermostat such as

changing set points and modifying programming schedules. If the thermo-

stat does not allow modiﬁcation of these functions, call the installer to per-

form desired changes.

Heat or Cool Indicator — A Heat or Cool indicator is located on the bot-

tom left cover of the thermostat. See Fig. 2. The light will be red if the ther-

mostat 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 thermo-

stat 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 ther-

mostat will remain in Unoccupied mode until the next Occupied start time.

Thermostat Programming Buttons — The thermostat has program-

ming 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.

Fig. 2 — Thermostat Front Panel Buttons

Fig. 3 — Thermostat Programming Buttons

The UPARROW 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 simul-

taneously. 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.

FAN BUTTON 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 FAN ON (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 Heat-

ing 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 ther-

mostat 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 ther-

mostat will provide automatic changeover from Heating to Cooling mode

and Cooling to Heating mode when required. The thermostat will automati-

cally switch to maintain the desired temperature setting. The thermostat does

not need to be manually changed from heating to cooling or cooling to heat-

ing operation.

NOTE: It is recommended that auto-changeover mode not be used if the out-

door temperature is consistently lower than 50 F (10 C) or greater than 80 F

(27 C). In these cases, select heating or cooling mode only.

HOLIDAY MODE — The Holiday button places the thermostat into Holiday

mode. During Holiday mode, the unoccupied set points are enforced. The

number of days the thermostat will be in Holiday mode can be set.

Set Clock — The Set Clock button allows the user to change the time and

day displayed on the thermostat. Press the Set Clock button to enter Set Time

mode. See Fig. 4. The current time will blink on and off. Press the UPAR-

ROW and DOWN ARROW buttons until the correct time is shown. Hold

down the buttons to quickly move through the time display. The AM and PM

annunciators will automatically change. To scroll through by hours only, press

and hold the Fan button while pressing the UP or DOWN ARROW buttons.

To ensure the schedules are properly followed, make sure that AM or PM is

correct for the time chosen. When the correct time is shown, press the Mode

button to modify the day of the week. The current day will blink on and off.

Press the UP ARROW and DOWN ARROW buttons until the correct day is

shown. Press the Set Clock button again to exit the Set Time mode.

Programming Thermostat Schedules — Before programming the ther-

mostat, plan the thermostat daily schedule. The schedule is divided into

7 days (Monday through Sunday). Each day can have 2 (Occupied 1, Un-

occupied), 3 (Occupied 1, Occupied 2, Unoccupied), or 4 (Occupied 1, Oc-

cupied 2, Occupied 3, Unoccupied) time periods. Each occupied time period

Fig. 4 — Setting the Clock

has a start time, stop time, heating set point, and cooling set point. The un-

occupied time period has a heating set point and a cooling set point. The

unoccupied time period is active whenever an occupied time period is not

active. Fill in Table 1 on page 12 as an aid to programming the daily

schedules.

NOTE: When the sensor detects light (the space is occupied), the thermostat

will enter into Occupied 1 mode. If the room is dark, the thermostat will

follow its programmed schedule. The Occupied 1 schedule should be turned

OFF to keep the thermostat from entering Occupied 1 while the room is un-

occupied. If the Occupied 1 schedule is turned ON, the thermostat will enter

into Occupied 1 per the schedule regardless of light activation. The Occupied

1 set points are used as the heating and cooling set points during light ac-

tivation. The Unoccupied set points should be used as non-work hour set

points (before 8:00 AM and after 5:00 PM) when using light activation. For

times when the building is unoccupied during work hours (Monday through

Friday, 8:00 AM to 5:00 PM), the Occupied 2 schedule should be turned ON,

and can be used for moderate energy savings with set points of 80 F for

cooling and 65 F for heating.

PROGRAMMING MODE — To program the daily schedules, perform the

following procedure:

1. Enter programming mode by pressing the Program button. The Occu-

pied 1 annunciator will appear on the thermostat display. See Fig. 5. Use
