Fancoil actuator / controller
3-speed fan control
THERMOREGULATION
Description
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.
