Terminal Box COMFORT Z3
Terminal Box COMFORT Z3 is a professional solution that brings together thermostat and actuator connections as well as pump and boiler control on a single panel for three-zone systems. The pump protection function automatically operates the pump at set intervals to extend its service life. The LED monitoring panel displays zone status along with pump and boiler activity in real time. Thanks to its compatibility with both 24V and 230V systems, it can be easily integrated into a wide range of projects.

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.
