Programming Heating and Cooling Schedule

IMPORTANT

Keep in mind that the up and down keys change the flashing number or word.

When multiple items are flashing, changes affect only one of the items.

The thermostat can control up to four different schedule periods per day:

Occupied1—Work arrival time. Period to keep space at a comfortable temperature.

Unocc1—Work exit time. Period to keep space at an energy-saving temperature.

Occupied2—Second occupied period.

Unocc2—Second unoccupied period.

NOTES:

—

Available schedule times are at 15-minute intervals.

—

With default settings, all four periods can be programmed. This can be

changed to allow only Occupied1 and Unocc1 programs. To use only

Occupied1 and Unocc1, see Step 8 in the Advanced Settings section.

Operating the Thermostat

Setting “System & Fan”

SETTING SYSTEM

The System selections vary based on the HVAC system type.

HEAT — thermostat controls the heating system.

OFF — both heating and cooling systems are off.

COOL — thermostat controls the cooling system.

AUTO — thermostat controls both the heating and cooling systems based on temperature.

63-2626

SETTING FAN

Fan selections vary based on the HVAC system type.

ON—fan runs continuously. Use this setting for improved air circulation or for more efficient

central air cleaning.

AUTO—fan is controlled by the system. Typically, the fan runs only during cooling or

heating operation.

Setting Temperature Overrides

There are three temperature override options:

—

Hold Temperature Until

Override, and

Holiday.

HOLD TEMPERATURE UNTIL

Holds the temperature temporarily until the time set by the user, or the next scheduled

period time:

Press an arrow key or the Override key. TEMPORARY SET TO appears on the

screen. The time defaults to the next scheduled period start time.

Use the Up and Down keys to change the desired temperature.

NOTE: If HEAT or COOL begins to flash, your temporary setting is at, or beyond,

the deadband. The thermostat operates based on the override setting

throughout the hold time.

Press NEXT.

63-2626

NOTE: The ability to change settings remains for approximately seven seconds.

Once neither the temperature nor the time continue to flash, you must

restart at step 1 to make changes.

Use the Up and Down keys

to set the desired time for

the thermostat to resume

the programmed schedule.

Replacing Batteries

With proper power and connections, the

thermostat does not require batteries.

Thermostats with batteries provide a

warning when the batteries run low. This

warning flashes on the main screen for

approximately 30 days.

NOTES:

—

If batteries are not replaced

when Low Battery warning is

flashing, the LO batt screen

displays continuously and

M22383

thermostat stops operating

until batteries are replaced.

Despite the low battery indicator, it is recommended that you replace the

—

batteries once each year. Do this to prevent leakage and to prevent the

thermostat and HVAC system from shutting down due to lack of thermostat

battery power.

63-2626

Replace the batteries as follows:

Remove the thermostat

from the base by pulling it

straight out.

WALL

Install two new AA alkaline

batteries with proper

polarization.

NOTES:

Always use AA

alkaline batteries.

PARTIAL LOCKOUT 1

This mode locks all keys except HOLIDAY, OVERRIDE, Up and Down. Standard

procedures are used to incorporate the temporary changes made with these keys. See the

Setting Temperature Overrides section for details.

PARTIAL LOCKOUT 2

This mode locks all keys except HOLIDAY and OVERRIDE:

—

Selecting HOLIDAY sets the temperature to the Unoccupied setting. The temperature

setting cannot be changed. The number of days to hold the holiday can be changed.

After this time, the next Occupied period switches back to the program settings.

Selecting OVERRIDE sets the temperature to the Occupied setting. The temperature

setting cannot be changed. The period of time to hold the override can be changed.

After this time, the next Unoccupied period switches back to the program settings.

To cancel the temperature override and follow the programmed schedule, press

CANCEL.

feature to eliminate guesswork

System & Fan

Override

Simply program the desired time to

have space at comfort temperature.

In addition, program temperature to

comfort temperature. The

M23048

thermostat activates the heating or

cooling at the proper time to reach the set temperature at the scheduled time.

NOTE: The setpoint changes gradually to use economical stages and avoid overshoot.

For example—the space will be occupied at 8:00 AM and the desired temperature is 70°F.

Set the Occupied1 period for 8:00 AM and 70°F. The thermostat turns on the heat prior to

8:00 AM to raise the temperature to 70°F by 8:00 AM.

The thermostat provides an alert that the heating or cooling system is coming on before a

scheduled time by displaying “Recovery” on the screen.

Setting Calendar

This thermostat is designed to, under normal use, automatically keep the current time and

day in the memory for up to ten years once the calendar is set. There are two ways to set

the calendar for this thermostat:

SETTING CALENDAR WHEN THERMOSTAT IS FIRST POWERED

When first powered, the thermostat proceeds through a sequence of screens to set the

Frequently Asked Questions and Answers

Q: When making changes, the wrong setting is being changed; Why?

A: Whatever is flashing on the screen is the item that the up and down buttons affect.

Q: The keys (some or all) do not work; why not?

A: Thermostat is locked. See Locked Keypad sections.

Q: Backlighting seems dim; is it designed to be dim?

A: When using batteries for power, install fresh AA alkaline batteries.

Q: Thermostat is asking for heating or cooling to come on (screen shows “Heat On” or

“Cool On” in display) but there is no heating or cooling running.

A: Call your local heating and/or cooling contractor to check your system.

Q: Why doesn’t the thermostat respond when I press a key?

A: Check to determine if the device is in the Locked mode. See Locked Keypad sections.

Q: Why doesn’t the fan run when the thermostat indicates “On”?

A: If the mode is Unoccupied, the fan control is the same as with the “Auto” setting. This is
