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.
