Honeywell Prestige IAQ, Prestige 2.0 Specifications

Prestige® IAQ and Prestige® 2.0 Thermostats

SUBMITTAL SHEET

APPLICATION

The Prestige IAQ and Prestige 2.0 are 7-Day programmable thermostats with auto changeover that are designed for single stage and multistage control of conventional and heat pump equipment such as rooftop units and split systems in residential and commercial applications. The thermostats control up to 3 heat / 4 cool conventional systems and up to 4 heat / 2 cool heat pump systems. The thermostat

controls humidication, dehumidication, ventilation, an economizer

and a lighting panel. Prestige IAQ has universal sensor inputs that

are used with remote indoor air temperature sensor(s), an outdoor air temperature sensor, a discharge air temperature sensor, a return air temperature sensor, an occupancy sensor for remote setback and dry

contact devices for displaying alerts.

• The thermostats are equipped with a 16:9 touchscreen TFT color display (WQVGA - 480 x 272 pixels).

• Provides a USB port to upload Dealer Information, Custom Reminders, Custom Event Schedules, Holiday Schedule and

Software Updates* and to download Data Logs.

• Provides remote access to the thermostat when used with the RedLINK internet gateway.

• Provides control using optional remote temperature and humidity sensors.

• Prestige IAQ integrates with the Niagara-AX framework.

* Software Updates only applies to Prestige IAQ.

Heat Indication:

Displays “Heat On” when the thermostat turns the heating on.

Auxiliary Heat Indication:

Displays “Auxiliary Heat On” when the thermostat turns the auxiliary heat on.

Interstage Differential:

Comfort: The thermostat keeps the indoor temperature within 1 degree of the

setpoint (droop less control). The thermostat turns on stage 2 when the capacity on stage 1 reaches 90%.

When the interstage differential is set to 1.0 or higher, the

thermostat stages the equipment based on how far the indoor temperature is from the setpoint.

Clock Accuracy:

± 1 minute per month at 77 °F (25 °C). ± 2 minutes per month

over the operating ambient temperature range.

Mounting Means:

Thermostat mounts directly on the wall in the living space using

mounting screws and anchors provided. Fits a horizontal 2 x 4 in. junction box. Use a cover plate and its mounting bracket to

mount the thermostat onto a vertical 2 x 4 in. junction box.

Equipment Interface Module (EIM) mounts on HVAC equipment

or on a wall in the equipment room.
