Air conditioner control EK-HB1-TP

Description
The actuator/controller Ekinex® EK-HB1-TP is designed to control a fancoil unit for space air-conditioning. It can operate as a simple actuator when paired with a KNX room thermostat or as a regulator/actuator acquiring temperature from a KNX room sensor or from a probe connected to an analog input. The device is suitable for 2-pipe hydraulic distribution systems with ON/OFF control of a thermal actuator valve and control of a fan driven by a brushless motor. Unused outputs can be configured as binary channels to perform other functions. The unit includes 2 inputs configurable as analog or binary. An integrated KNX bus communication module is provided and the product is intended for 35 mm DIN-rail mounting. Power for the electronics is supplied via the KNX bus; 230 Vac mains supply is required for load power.
