The T-box serves as the central regulation hub for Flowair HVAC installations, replacing individual unit controllers with a single large touchscreen interface. Designed for commercial and industrial spaces requiring coordinated heating, cooling, and ventilation, it connects to up to 31 Flowair devices — LEO fan heaters, ELiS electric heaters, OXeN air curtains, KM mixing chambers, and LEO COOL coolers — providing unified zone management from one panel.

How does the T-box regulate temperature across multiple zones?

The controller assigns individual temperature setpoints and weekly schedules to each connected zone. In heating mode, units activate when room temperature falls below the setpoint; in cooling mode, the valve opens when measured temperature exceeds the target. The automatic 3-step air flow mode adjusts fan speed based on the difference between actual and desired temperature, while manual mode holds a constant speed. For LEO BMS-compatible units, the T-box supports smooth 0–100% proportional control.

What building integration options does the T-box support?

A single BMS address allows the entire T-box managed installation to connect to a higher-level building management system for centralized monitoring and override control. The controller also includes antifreeze protection that automatically activates heating when room temperature approaches freezing, preventing coil damage in unoccupied periods. A weekly programmer with individual daily schedules per zone enables set-and-forget operation aligned with facility occupancy.
