APPLICATION
RedLINK VisionPRO is a 7-Day programmable thermostat with auto
changeover that is 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. RedLINK
VisionPRO can be used with or without an equipment interface module.
The thermostat controls 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. Universal sensor inputs 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 thermostat is equipped with a touchscreen display with a 2 line
message center.
• Provides a microSD card 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.
• Thermostat integrates with the Niagara-AX framework.
