GRHA-0xCH-KNX

Heating Modules

The GRHA-04CH-KNX and GRHA-08CH-KNX devices are EIB/KNX DIN rail modules for electrothermal valves with Triac outputs at 24-230V AC; the devices include inputs for dry, potential-free, contacts. Each thermostat module manages 2 stages with an integrated PI controller for controlling heating and cooling equipment, valves, and 2 or 4 pipe fan coils.
