Programming Schedules  — 

The Comfort Pro pro-

grammable thermostat gives the user the option of program-

ming for all days, weekdays, or weekends. The thermostat is 

preprogrammed at the factory with the same settings for all 

seven days. See Table 2.

Table 2 — Schedule Factory Settings

Prior to programming a customized schedule, fill out the 

Daily Schedule Planner in Table 3.

Table 3 — Daily Schedule Planner

NOTE: The cooling temperature set point must be higher than the heating 
temperature set point. (The temperature difference may be changed in the 
advanced set up configuration by the installer.)

To set up a different schedule, perform the following proce-

dure (see Fig. 3):

1. Open the thermostat front panel door.
2. Press the 

set schedule days

 button until the screen dis-

plays the programming method of 

all days

 or 

weekend

 icons at the right of the screen. Press the 

up 

or

down

 button to change as necessary to the desired pro-

gramming selection icon.

3. Press the 

period 

button to continue programming the 

thermostat. The periods are displayed as 

P1

 through 

P4

 if 

Option 25 was set to 4 periods/day or 

P1

 through 

P2

 if 

Option 25 was set to 2 periods/day. Press the 

period

 but-

ton to display the next programmable period.

4. As each period is displayed, the comfort setting that is 

used for that period is displayed, along with whether it is 

in the occupied, unoccupied or limit configuration as 

shown by the triangle over the 

OCC

UNOCC

 or 

LIM-

IT

 buttons. Change the 

OCC,

 

UNOCC

 or 

LIMIT

 con-

figuration by pressing the appropriate button and the tri-

angle will move to that setting.

5. To change the time for a period, press the 

start time

 but-

ton and use the 

up 

and

 down

 buttons to change the hours. 

6. Press the 

start time 

button again to change the minutes 

using the 

up 

and

 down

 buttons.

7. To go to the next programming period press the 

period

button twice. Enter in the changes for all of the periods as 

described in Steps 4, 5 and 6 above.

8. Press the 

done

 button when complete.

9. Close the thermostat door.

NOTE: Once a change is made to the programming schedule, 

it is saved when the user moves along to the next programming 

interval or level. Changes within a given programming period 

are considered temporary changes that require user confirma-

tion by either closing the door or pressing the 

done

 button 

which would confirm any changes made up to that point.

If dashes "--:--" appear in the display this is an indication 

that the start time in the period displayed is not the same start 

time in all periods.  Press the 

start time

 button and update the 

time for the HVAC equipment to start.

Temporary Hold Override  — 

The user can temporar-

ily change the temperature from the programmed set points. 

Perform the following steps to temporarily override the ther-

mostat:

1. Open the thermostat front panel door.
2. Press the 

up 

or

 down

 button. This will cause the set point 

to be displayed.

3. Press the 

up 

or

 down

 button again to increment or decre-

ment the displayed set point. This will cause the tempo-

rary hold icon to be displayed below the temperature and 

replace the clock with the 0:15 minute override time.

4. The temporary hold remains active until a power cycle is 

encountered, the override time has expired, off mode is 

selected, or the user presses the 

hold

 button.

5. To change the override time displayed in the clock loca-

tion, press the 

start time

 button. Each press of the 

start 

time

 button increments the override time by 15 minutes 

up to the maximum value set by the installer.

6. Once the temporary hold is cleared, the override will be 

considered inactive and the set point will reflect the pro-

gram schedule set point.

7. Close the thermostat door.

Holding Temperature Set Points  — 

The user can 

override the programmed temperature settings and hold the 

temperature at a specific setting. To override the temperatures, 

perform the following procedure:

1. Open the thermostat front panel door.
2. Press the 

hold

 button (see Fig. 4). This will hold the cur-

rent comfort setting and the program schedule will be ig-

nored as long as the hold remains active.

3. Pressing the 

hold

 button again will return the thermostat 

to the current programming schedule.

4. Close the thermostat door.
