Fancoil controller 3 speed

DIN-Rail mount modules



The Ekinex® EK-HA1-TP fancoil actuator / controller allows to control a fan coil unit for the air conditioning of a room. The device can perform the function of simple actuator in combination with a KNX room thermostat or that of actuator / controller with acquisition of the temperature value by a KNX room sensor or a probe connected to an analog input. The device is suitable for 2-pipe hydraulic distribution systems with ON / OFF control of one electrothermal shut-off valve actuator and a 3-speed fan. The outputs not used to control the fan coil unit can be configured as binary output channels for different functions. The device is equipped with 2 inputs freely configurable as analog or digital. The device integrates a KNX bus communication module and is realized for mounting on a standard 35 mm DIN-rail. The device is supplied by the KNX bus and requires an additional 230 Vac power supply to operate.

Technical data
Power supply
  • Voltage (loads) 230 Vac 50/60 Hz
  • Voltage (electronics) 30 Vdc by KNX bus
  • 2 freely configurable for passive temperature sensors (10 kΩ NTC at 25°C) or as potential-free binary inputs
  • 3 interlocked relay outputs to control a 3-speed fan (or configurable as binary outputs for different applications)
