The Saia PCD TR80 series is a wall-mounted HVAC room temperature and humidity controller with integrated light, blind, and occupancy management—all accessible through a single bezel-less glass front panel. Designed for today’s healthy buildings, the TR80 replaces the traditional clutter of multiple wall displays and switches, combining intuitive capacitive touch control with comprehensive environmental sensing and Modbus-based communication into one compact device.

Integrated Room Control

• HVAC, Light & Blind in One Device: The TR80 consolidates temperature and humidity regulation, fan speed selection, lighting control (up to 4 groups with DALI64 Modbus), and sun blind/shade control (up to 2 groups) into a single wall module. This eliminates the need for separate thermostats, light switches, and blind controllers, reducing wall clutter and simplifying installation.
• 10 Dynamic Backlit Capacitive Touch Keys: The capacitive touch interface provides tactile feedback for fan speed, setpoint adjustment, light dimming level, and blind rotation—all independent of bus communication cycle delays. The icon-based layout and multi-language support make the interface intuitive for employees and guests alike.
• Fan and Heat/Cool Configuration: Fan modes support EC Fan, 3-Speed, 2-Speed, and 1-Speed configurations. Up to two heat sources and two cool sources can be selected, enabling flexible HVAC zoning strategies within a single room.

Advanced Multi-Sensor and Air Quality Monitoring

• On Board Temperature & Humidity Sensors: Integrated sensors provide precise ambient temperature and relative humidity measurements without the need for external probes.
• External Air Quality Sensors: The TR80 can display indoor air quality parameters using external sensors—CO₂, TVOC, PM2.5, PM10, Air Flow, and Room Pressure—essential for monitoring and maintaining healthy building environments. This data is readily available without additional wall-mounted display units.

Hospitality and Occupancy Management

• Multiple Occupancy Modes: The controller supports various occupancy modes including Occupied, Unoccupied, Bypass, Away, and Holiday—enabling demand-driven energy savings in hospitality and commercial environments.
• ‘Do not Disturb’ & ‘Make up Room’ Options: Designed for the hospitality sector, these modes provide guests with intuitive privacy and housekeeping signalling directly from the wall module, integrating seamlessly into hotel room management systems.

Accurate Light and Blind Control

• DALI64 Modbus Lighting: The TR80 controls up to 4 lighting groups with 0-100% dimming command through DALI64 Modbus directly, creating user handling that is independent of execution delays caused by bus communication cycles.
• Sun Blind & Shutter Control: Up to 2 blind/shutter groups with setting of blind level and rotation over a 0-100% command, enabling precise daylight management and glint reduction throughout the day.

Applications

• Commercial office HVAC and lighting management with occupancy-based control
• Hotel rooms and guest suites with integrated climate, lighting, and privacy controls
• Hospitals and healthcare facilities requiring easy-to-clean surfaces and multi-sensor air quality monitoring
• Educational institutions, conference centres, and co-working spaces with demand-driven energy strategies
• Any commercial building seeking to consolidate room control into a single, hygienic, user-friendly wall module
