CAUTION

Disconnect power supply before beginning instal-

lation to prevent electrical shock or equipment

damage.

LOCATION

Locate the thermostat about 5 ft [1.5 m] above the floor

on an inside wall in an area with good air circulation at

average temperature.

Do not mount the thermostat where it can be affected by:

— drafts or dead spots behind doors or in corners.

— hot or cold air from ducts.

— concealed pipes and chimneys.

— radiant heat from the sun, fireplaces, or appliances.

— unheated (uncooled) areas behind the thermostat,

such as an outside wall.

MOUNTING AND WIRING

Disconnect power supply before beginning installation

to prevent electrical shock or equipment damage.

All wiring must comply with local codes and ordi-

nances.

T822A,D,F,G and TS822A Thermostats are designed to

be mounted vertically on a wall or a vertical outlet box.

T8022D is designed to be mounted horizontally on a wall.

In a 250 or 500 mV application, use No. 14 wire if

possible and make the run as short as possible; remember

this when selecting a location. For maximum wire lengths

of a 750 mV application, see Table 1.

1. In replacement applications, check the existing ther-

mostat wires for cracked or frayed insulation. Replace any

wires in poor condition. If the wire is plastered into the

wall, make a hole next to the wires and loosen the wires so

they can be pushed back into the wall later.

2. In new installations, run wiring (if necessary) to the

thermostat location.

3. Connect the wires to the terminals on the back of the

thermostat. See Figs. 1 through 6 for internal schematics

and typical hookup diagrams.

Application

T822A,D,F, TS822A, and T8022D Thermostats pro-

vide control of heating systems. T822G provides control of

AC heating or cooling appliances.

The T822A two-wire switch thermostat provides low

voltage control of heating systems and features a fixed heat

anticipator.

The T822D and T8022D two-wire, mercury switch

thermostat provides low voltage control of heating systems

and features an adjustable heat anticipator.

The T822F three-wire, mercury switch thermostat pro-

vides low voltage control of heating systems and features

an adjustable heat anticipator and AUTO-ON fan switch-

ing.

The T822G three-wire, mercury switch thermostat pro-

vides low voltage control of AC heating and cooling appli-

ances and features an adjustable heating anticipator and

nonadjustable cooling anticipator.

The TS822A two-wire, mercury switch thermostat pro-

vides millivoltage control of heating systems.

T822A,D; TS822A, and T8022D Thermostats are avail-

able with a positive OFF switch. All models are available

with temperature range stops.

Recycling Notice

If this control is replacing a control that contains mer-

cury in a sealed tube, do not place your old control in

thetrash.

Contact your local waste management authority for

instructions regarding recycling and the proper disposal of

this control, or of an old control containing mercury in a

sealed tube.

If you have questions, call Honeywell Inc. at
