Fancoil controller 3 speed

Code: EK-HA1-TP

Description

The Ekinex® EK-HA1-TP actuator / controller allows to control a fan coil unit for the ambient air conditioning. 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 an 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 outputs for different applications.

The device is also 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.
