Overview
Control Box – Control Units for the Management of Radiant Systems
The Control Boxes are control units designed for the advanced control of radiant systems, working in perfect synergy with our manifolds and electrothermal heads. Thanks to precise and reliable management, these units ensure optimisation of energy consumption and tailored thermal comfort. They can manage up to 8 radiant zones simultaneously and are available both wired and wifi.
Insights
The Control Box unit is the heart of the control system, connecting the room thermostats to the M30X1.5 thermostatic heads installed on the manifolds. Operation takes place as follows:
1. Temperature detection – The room thermostats monitor the temperature of each zone of the building. 2. Signal processing – The collected data is sent to the Control Box, which activates or deactivates the electrothermal heads according to the desired temperature. 3. Thermal flow regulation – The thermostatic heads modulate the passage of water in the manifolds, guaranteeing balanced heating and efficient consumption.
