Terminal Box COMFORT Z9
Terminal Box COMFORT Z9 provides comprehensive HVAC control by combining temperature control for 9 different zones in large buildings with pump and boiler management. This model, which provides a reliable solution for large-scale projects, allows real-time monitoring of all zones with LED status indicators. Change-over support enables the system to quickly switch to heating or cooling mode when needed.

COMFORT Series Terminal Box models offer an advanced HVAC solution by combining zone management with professional pump and boiler control. By bringing thermostat, actuator, pump, and boiler connections together at a single central point, this series ensures more efficient, synchronized, and safe system operation. The pump protection function automatically runs the pump at set intervals, extending the equipment’s service life. LED status indicators provide clear monitoring of zone, pump, and boiler activity, while change-over support enables seamless management of heating and cooling transitions throughout all four seasons.
Change Over
The device is suitable for both heating and cooling systems. Switching signals between the two modes are transmitted to connected thermostats with change-over capability, synchronizing the system modes.
This feature provides significant benefits in terms of energy optimization, especially in buildings that operate year-round (four-season operation).
Pump and Boiler Control
The boiler control output provides safer and smoother system transitions by applying a 4-minute delay during start-up and shut-down.
