SELECTION/APPLICATION

Selection/Application

The T8624 Thermostat uses the latest microelec-

tronic 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

needs.

PROGRAMMING

Does the thermostat selected accommodate the

customer’s daily schedule, lifestyle or work schedule?

The choices are:

*Model not currently available to control multistage

equipment.

IF NEW CONSTRUCTION APPLICATION, CON-

SIDER:

• Equipment type (see manufacturer specifications).

—Staging required.

—System switching required.

—Fan switching required.

• Control wiring—number of conductors required

to operate equipment and thermostat.

IMPORTANT: The T8624 requires an additional con-

ductor to transformer common to provide continu-

ous 24V power for thermostat operation.

IF RETROFIT/REPLACEMENT APPLICATION,

CONSIDER:

• Equipment requirements.

— Staging (heat stages, cool stages).

— System switching (manual: HEAT-OFF-COOL;

automatic: HEAT-AUTO-COOL-OFF). Emer-

gency heat for heat pump application not pro-

vided on T8624.

— Fan switching; does fan come on automatically

from thermostat on cooling only (typical gas/

oil heating), or on call for cool and heat (typical

electric heat with single speed fan)?

• Existing wiring

— Are there enough conductors to operate the equip-

ment and the thermostat? Can a new cable be

pulled?

IMPORTANT: The T8624 requires an additional con-

ductor to transformer common to provide continu-

ous 24V power for thermostat operation.

programmming and the override features that will best

suit the application? The choices are:

SINGLE-STAGE HEAT PUMPS

If home/building owner has a single-stage heat pump,

one option is to use a T8624C or D (see Fig. 8).

The T8624C is a two-stage heating, one-stage cool-

ing programmable thermostat. The T8624D is a two-

stage heating, two-stage cooling programmable thermo-

stat. What both thermostats have in common is separate

W1 and W2 (first and second stage heat) terminals. In

both cases, the W1 can be used for changeover in heat-

ing.

For single-stage compressor applications (both first-

stage heating and first-stage cooling energized through

the Y terminal), simply jumper Y1 and W1.

Note that the recovery algorithm of the T8624 may

cause the compressor to cycle on and off during recov-

ery.

Although the cycle rate for the first stages of heat and

cool are set for hot water systems, the second stage of the

T8624 must be adjusted. Turn the cycle rate adjustment

screws to the hot water setting on both the T8624C and

D to achieve the cycle rate appropriate for heat pumps.

If changeover is utilized in the cooling mode, apply a

normally closed relay.

The above application should be used only on single-

stage heat pumps.
