The ECB8HC-230 control box, powered by 230 V AC, is designed to manage underfloor heating and cooling systems in up to 8 zones. It allows quick connection of 230 V wired thermostats and NC-type thermal actuators (NC-type means they are closed when are not powered). The device includes a built-in pump control module and volt-free relay outputs for controlling the heat source (NO/COM/NC) and the cooling source (NO/COM).
The HEATING / COOLING operating mode is switched via an external volt-free contact (CO INPUT), with the current mode indicated by LED lights – red for heating and blue for cooling.
The DEW INPUT terminal is used to connect a dew point sensor or hygrostat contact. When condensation is detected, it automatically disables the pump and cooling source to protect the system from moisture buildup. The control box also allows setting a relay switch-off delay (0 / 3 / 5 / 15 minutes) and is suitable for wall or DIN-rail mounting.

Control box is the main element of the underfloor heating control system. It is equipped with 230V voltage connectors for the thermostats, pump, and thermoelectric actuators. It allows for the control of 8 heating zones in a combination of connections – 2 wired and 6 wireless thermostats. It works with NC-type thermoelectric actuators. The control box has a built-in control module for heating devices, e.g. gas boiler (voltage free output). Wired control is done by directly connecting the thermostat to the control box by wires. The applied thermostats can be battery-powered or powered by 230V AC voltage. Wireless communication is over ZigBee 3.0 technology. The “ENGO binding” function provides wireless and direct control to dedicated ZigBee thermostats using the internet gateway. Additionally, gateway makes possible to control control box over Internet by ENGO Smart/TUYA Smart mobile applications.
