KNX devices with function of actuator and tempera-
ture controller for convectors and
in KNX installations for control of homes and build-
ings.
Descrizione
The EK-Hx1-TP series includes three devices ekinex
KNX
S-mode
suitable
applications. The EK-HC1-TP is used for installations in
2 or 4-pipe hydraulic distribution systems with ON / OFF
control of an electrothermal actuator on a shut-off valve;
control of a 3-speed fan or 0-10 V control of a fan with
brushless motor; this version allows manual control of
the outputs through the membrane pushbuttons. The
EK-HA1-TP version is used for installations in 2-pipe
hydraulic distribution systems with ON / OFF control of
an electrothermal actuator on a shut-off valve and a 3-
speed fan. EK-HB1-TP version is used for installations
in 2-pipe hydraulic distribution systems with ON / OFF
control of an electrothermal actuator on a shut-off valve
and 0-10 V control of a fan with brushless motor.
The devices can be configured as actuators for the
control of a fan and a maximum of two shut-off valves
ON / OFF on the heat exchange coils , in combination
with a room thermostat installed on the KNX network .
The devices can be configured as controllers / actuators
with acquisition of the temperature of a room sensor
KNX or via a sensor installed on the return duct and
connected to one of the analog inputs.
