Description
The PRO1 IAQ T955WH is a stand-alone wireless touchscreen programmable thermostat kit designed for flexible placement and easy HVAC integration. The thermostat communicates wirelessly with an included base module that wires directly to your HVAC equipment, giving you the freedom to mount the thermostat anywhere in the space — up to 100 feet away with no obstructions, or up to 50 feet through standard residential construction.
Compatible with most 24V heating and cooling systems, the T955WH supports up to 2 stages heat / 2 stages cool for conventional systems and up to 3 stages heat / 2 stages cool for heat pump applications. The large 13 square inch backlit touchscreen and menu-driven interface make programming straightforward for homeowners and technicians alike.
The system is expandable with optional wireless accessories. Up to four R251W Wireless Remote Indoor Sensors can be added to sense and display room temperature or allow remote override (24VAC required at thermostat for indoor sensor communication). The optional R250W Wireless Remote Outdoor Sensor displays outdoor temperature and enables dual fuel balance point control, eliminating the need for a separate fossil fuel kit.
