The T8611M Chronotherm III Programmable Thermostat provides automatic control of multistage heat pump systems and offers users the highest standard of comfort and convenience available with energy savings.

T8611M

■ Full seven-day program capability; different sched-

ules may be selected for every day.

■ Can be programmed in hand (with batteries in-

stalled) or on the wall to provide up to four tem-

perature periods per day.

■ Large digital clock (liquid crystal display) indi-

cates continuous time-of-day, day-of-week, cur-

rent period and room temperature.

■ Adaptive Intelligent Recovery™ brings room tem-

perature to programmed temperature at program-

med time, maximizing comfort and energy sav-

ings.

■ Temperature control program maintains tempera-

ture within 1° F of setpoint.

■ Temporary program override available by using—

—WARMER and COOLER keys.

—SKIP next period key.

—CHANGE to last period key.

■ HOLD TEMP key provided for indefinite program

override (vacation/holiday).

■ Installer self-test with time delay override saves

installation time.

■ SYSTEM light-emitting diode (LED) on thermo-

stat indicates system is energized.

■ AUX. HT., EM. HT., CHECK LEDs available on

select models.

■ Automatic heat/cool changeover.

SELECTION/APPLICATION

Selection/A pplication

The T8611 Thermostat uses the latest microelectronic design and control technology to provide home and building owners with the highest level of comfort available and optimal energy savings in a package that is easy to use and easy to live with.

The following section is a guide to selection and application of the best thermostat to meet individual customer needs.

PROGRAMMING

Does the thermostat selected accommodate the customer’s daily schedule, lifestyle or work schedule? Refer to choices below.

TRADELINE Daily Temperature

Device Programming Selection

T8611G,R* Weekday, 4 heat and

Sat, Sun. 4 cool

T8611M 7-day 4 heat and

(each day 4 cool

different)

IF RETROFIT/REPLACEMENT APPLICATION, CONSIDER

• equipment requirements — system switching (manual: EM. HT.-HEAT-OFF-

COOL, automatic: EM. HT.-HEAT-OFF-AUTOCOOL).

— unique heat pump functions of emergency or

supplemental heat, changeover on heat or cool, and status indication.

— Table 3 lists typical applications by manufac-

turer.

• existing wiring — Are there enough conductors to operate the equip-

ment and the thermostat? Can a new cable be pulled?

• existing thermostat — Table 3 is a guide for replacing popular Honeywell

standard nonprogrammable thermostats with a T8611.

SECURITY

Does the thermostat selected provide access to programming and the override features that will best suit the application? Refer to choices below.

*Specifications form 68-0057 for information.

IF NEW CONSTRUCTION APPLICATION, CONSIDER

• equipment type (see manufacturer’s specifications) — system switching required — status indication provided

• control wiring—number of conductors required to operate equipment and thermostat.

IMPORTANT: The T8611 requires a conductor to trans-

former common to provide continuous 24V power for thermostat operation. This feature is commonly specified and provided by equipment manufacturer.
