Fancoil controller 3 speed and 0-10V

The Ekinex® EK-HC1-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 or 4-pipe hydraulic distribution systems with ON / OFF control of one or two electrothermal shut-off valve actuators and a 3-speed fan or a brushless motor driven 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 3 inputs freely configurable as analog or digital. The device is fitted with membrane pushbuttons for manual command and LED’s for status indication; a pushbutton allows to switch between automatic and manual operation modes. 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

Inputs

3 freely configurable for passive temperature sensors (10 kΩ NTC at 25°C) or as potential-free binary inputs

Outputs

• 1 to control a brushless motor driven fan with 0-10 V signal 
• 3 interlocked relay outputs to control a 3-speed fan (or configurable as binary
• outputs for different applications)
• 2 relay SPST (single pole, single throw) to control two ON / OFF valves (in 2 or 4-pipe hydraulic distribution systems)

Delivery

Delivery includes a terminal block for connection to the bus.
