ENGO 8 Zone Wiring Centre for Heating & Cooling
£47.50 excl VAT / £57.00 incl VAT
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 hygrostatcontact. 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.
