6.2. SWING SETTING

A thermostat works by turning your heating or

cooling system on and off whenever the room

temperature varies a certain number of degrees

from the set-point temperature. This variation is

the "swing." Your system should cycle on about 3

to 6 times per hour. A smaller swing number

increases the number of cycles, so room

temperature is more constant. A larger swing

number decreases the number of cycles, saving

energy in most cases. To change the SWING value

from the main menu:

• Use UP/DOWN ARROW to change the flashing

temperature setting for MON EVE.

• Touch YES to accept the displayed temperature

and advance to Set MON NITE start time.

• Touch EXIT to return to the main screen.

6.5. PROGRAM LOCK

7.2. SMART RECOVERY SWITCH #2

The Program Lock allows the owners/operators to

prevent unauthorized changes to the thermostat’s

settings. When the thermostat is locked, a three

digit code is set (000 to 999). That code must be

re-entered before locked settings can be changed

without performing a hardware reset of the unit.

The status of the lock is indicated by an open or

closed padlock icon.

Smart Recovery allows your HVAC system to

attempt to recover from a setback period and

reach your desired comfort temperature set point

by the beginning of your programmed comfort

period. This option allows you to choose whether

to use Smart Recovery.

When enabled, Smart Recovery will initiate if:

• Recovery is from an evening setback to

morning comfort or day setback to evening

comfort period.

• In Heat mode the temperature set point of the

comfort period must be higher than the setback

period.

• In Cool mode the temperature set point of the

comfort period must be lower than the setback

period.

• The estimated Smart Recovery time must be

longer than 15 minutes for a Smart recovery to be

initiated.

6.5.1. TO SET CODE

• From the main menu touch MENU

• SCROLL to SET KEYBOARD LOCK.

• Touch YES. ENTER OLD CODE and both open

and closed padlock icons will be displayed. The

default code is "000".

• Hold UP/DOWN arrows to count to code

number.

• Touch YES. ENTER NEW CODE will appear.

• Hold UP/DOWN arrows to count to code

number (Record Code Number).

• Maximum Smart Recovery time is one hour.

from the wall by pressing up on the thumb latch at

the bottom of thermostat and swinging the body

up and away to remove it from the wall.

• The Smart Recovery temperature set point must

be achievable. If a desired smart recovery is

repeatedly ignored by your thermostat. That is an

indicator that you should modify your program so

that the recovery can be achieved within the 1

hour limit.

• A Smart Recovery may not be initiated for 48

hours after the units programs have been

changed. This allows the unit to gather the data

necessary to predict a Smart Recovery time.

2. Remove the used batteries. See battery location

and polarity in figure on Page 12.

3. Install two new Energizer^®or DURACELL^®

"AA" size alkaline batteries in the battery

compartment. Observe the polarity marking

shown in the compartment.

4. Hang the top of the unit by the tabs at the top

corners of the base, then snap the bottom of the

unit into place. Do not use unnecessary force. If

the body does not snap into place easily, remove

the body, re-hang it from the tabs and try again.
