Actuators / controllers for fan_coil
Code
: EK-HA1-TP / EK-HB1-TP / EK-HC1-TP
Data sheet STEKHC1TP_EN
KNX devices with function of actuator and tempera-
ture controller for convectors and fan-coil
. To be used
in KNX installations for control of homes and build-
ings.
Descrizione
The EK-Hx1-TP series includes three devices ekinex
®
KNX S-mode suitable for temperature control
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.

Integrated Temperature Controller
• Settings via bus with Setpoint Setpoint single or
related activated through the way HVAC System
• ON / OFF or PWM ( pulse width modulation ) of the
water flow to the heat exchange coils
• ON / OFF at 1-3 windows with hysteresis or PI
( Proportional Integral ) of the air flow of the fan
• Switching heating / cooling from the bus or
automatically according to the ambient temperature
or according to the temperature of the fluid at
discharge
• Ability to enable a compensation curve climatic
cooling
• Automatic hot-start and cold -start the fan based on
the actual temperature of the heat exchanger
• Trigger fan in case of stratification in large
environments
• Function monitoring condensate level
• Monitoring function operating hours with signaling
replacement filter
