GENERAL

The Totaline® 7-day programmable thermostats are wall-

mounted, low-voltage thermostats which maintain room tem

perature by controlling the operation of an HVAC (heating,

ventilation and air conditioning) system. Separate heating and

cooling settings and auto-changeover capability allow setback

of programming schedules for energy savings.

All thermostats allow up to 4 time/temperature settings to

be programmed per 24-hour period. Each thermostat stores

programs for 7 independent days. Batteries are not required.

During power interruption the internal memory stores pro

grams for an unlimited time and the clock continues to run for

at least 72 hours.

The Energy Star logo indicates this thermostat is designed

to significantly improve heating and cooling comfort levels

while reducing the cost to heat and cool indoor air space.

THERMOSTAT OPERATION

Thermostat Display — The thermostat display is locat-

ed in the top center of the thermostat. See Fig. 1. The following

information can be displayed on the screen:

• mode (OFF, HEAT, COOL, AUTO, or EHEAT [P274-

1200,1300 models only])

• fan setting (ON or AUTO)

• hold status

• auxiliary heat status (AUX HT [P274-1200,1300 models

only])

• room temperature

• desired temperature

• clean filter status

• time of day

• day of the week

Programming the Thermostat — The thermostat has

programming buttons which allow time and temperature to be

entered into the thermostat. The programming buttons are be

hind the thermostat cover. To access the programming buttons,

pull on the hinged thermostat cover. See Fig. 1. The program

ming buttons are: Copy Previous Day, Program, Mode, Change

Day, End Program, Fan, Set Time, Reset Filter, and Hold.

The Up and Down buttons are used to change the current,

desired temperature set point and to scroll through program

ming settings. The Up and Down buttons are accessible from

the outside of the thermostat.

The daily schedule can be overridden in 2 ways: pressing

the Hold button or pressing the Up and Down buttons to

change the temperature set point.

HOLD BUTTON — Pressing the Hold button disables the

time and temperature schedule and holds the current desired

temperature set point. When a Hold is active, the HOLD

annunciator is displayed on the thermostat screen. The Hold

will remain active indefinitely. While HOLD mode is active

the set points can be adjusted and will remain at last changed

set point in HOLD mode for as long as HOLD mode remains

active. To release the Hold, press the Hold button a second

time.

FAN BUTTON — The Fan button selects fan operation.

When the fan is set to ON, the fan will run continuously for

improved air circulation. When the fan is set to AUTO, the fan

will run during heating and cooling operation only.

MODE BUTTON — 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 tempera

ture is below the heating set point). If COOL is selected, the

thermostat will only enter Cooling mode (if the room tempera-

ture 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 settings. Heat

pump thermostats also have an EHEAT selection. If EHEAT is

configured by installer, the unit will use the second stage of

heating to provide heating if necessary. The annunciator for

each selection will be displayed on the thermostat when

selected.

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.

NOTE: It is recommended that auto-changeover mode not be

used if the outdoor temperature is consistently lower than 50 F

or greater than 80 F. In these cases, select Heating or Cooling

mode only.

SMART RECOVERY (HEATING MODE) — The smart

recovery function is designed to save energy by gradually

adjusting temperatures to meet scheduled set points. The Smart

Recovery function begins 1 to 1.5 hours before a scheduled set

point increase and gradually adjusts room temperature so the

temperature is at the new set point when the time period

begins. This is more efficient than making the system run at

full capacity until the desired temperature is met.

NOTE: Smart recovery does not apply to cooling operation.

IMPORTANT: Read entire instructions before program-

ming the thermostat.
