MENRED H-BOX208 and H-BOX212 are central wiring centers designed for hydronic underfloor heating systems. They provide a convenient connection point between room thermostats and thermal actuators while also supporting boiler and circulation pump linkage.
The series is available in two versions: H-BOX208 with 8 zone outputs and H-BOX212 with 12 zone outputs.
The H-BOX208 / H-BOX212 series provides two potential-free relay outputs: one for boiler linkage and one for circulation pump linkage. This allows the wiring center to coordinate room thermostat demand with the wider hydronic heating system.
