VisionPRO® 8000 with RedLINK™
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 humidification, dehumidification, 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.

SPECIFICATIONS (CONTINUED)
Heat Indication:
Displays “Heat On” when the thermostat turns the heating on.
Auxiliary Heat Indication:
Displays “Aux 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.
