Programmable Thermostat

Gree’s full line of wall thermostats are designed to enhance every PTAC application. The TopTech Comfort Series

of thermostats consists of programmable and non-programmable air conditioner and heat pump controls. These

units feature non-mercury, non-lead based electronic controls built into a subtle, 1.2 inch (30.5 mm) slim plastic

enclosure. Wall thermostats are simple and easy to use. Wall thermostats provide better temperature and humidity

control as they can be placed in an optimal position in the room. All Top Tech 400 series thermostats features

Temperature Range Limiting to help prevent wasted energy and optimize energy savings opportunities. See page

30 for thermostat wiring instructions.

In addition, multiple GA series PTACs can be controlled by a single wall thermostat. See page 40 for wiring

multiple PTAC units to one thermostat.

building on central HVAC system.

RETROFIT/REPLACEMENT

If you are replacing a unit in an existing wall sleeve,

your options include:

• Replace the existing wall sleeve with the

the polymer wall sleeve. See accessory sleeve

section for selecting the correct sleeve for

your application.

NOTE: in most cases, when replacing the

wall sleeve, the exterior grille must also be

replaced.

• Use an existing sleeve and exterior grille. The

replacing packaged terminal air conditioning units in

an existing building, Gree GA Series will meet your

needs.

The Gree GA series Packaged Terminal Air

Conditioning (PTAC) unit is designed to meet the

needs of the architect, engineer, and contractor. For

unit installation, Gree’s expert support network will

assist in all applicable aspects of the construction

project, from preparing a budget to start-up.

The following major competitors’ wall
