TRDA controller with frost protection

TRD is a temperature controller for use in small and medium-sized HVAC systems where it controls heating valves, electric heating batteries and heat recovery devices.

TRD is particularly suitable for ventilation systems in which the supply-air temperature or the room temperature is to be held constant. TRD has integrated active frost protection, thus reducing installation costs in systems that require frost protection. With TRD, our customers receive the perfect combination of exceptional quality and accurate control.

  • Integrated active frost protection
