HVAC APPLICATIONS
Actuator / controller for fan-coils
KNX module that can be used as an actuator (in combination with a KNX
room thermostat) or actuator / controller (receiving the temperature
value from a KNX sensor, another KNX device or an NTC temperature
sensor connected to an analogue input). Versions for controlling 3-speed
fan units or with brushless motor and inverter board (control voltage
0...10V). For systems with 2- or 4-pipe hydraulic distribution. ON / OFF
control of one or two electrothermal valve drives. The outputs not used
for the control of fan-coils can be used as outputs to carry out other bus
functions. Panel mounting on DIN rail EN 60715 (4 MU).

EK-HE1-TP
Confi gurable logic module
KNX module to carry out logic functions and calculations on values of
KNX communication objects. 4 confi gurable channels for the connection
of potential-free contacts. Flush-mounting in wall box or on DIN rail EN
60715 using the EK-SMG-35 support (included in the delivery). Power
supply via KNX bus.
Implementable blocks
- Logic: combination of binary inputs according to logical operations
- Mathematical: mathematical calculations on one or more inputs
- Range: scaling (or limitation) of input values to different ranges
- Mapping: translation of a set of values of an input (up to 8 points) into
a different set of output values
- Conversion: conversion of one communication object to another with
different KNX data type (DPT)
- Timer: one-shot (monostable) or oscillator (astable) timing with delays
that can be set on activation and deactivation
- Comparison: return of the result of an arithmetic comparison (equal,
greater, lesser, etc.) between two input values
- Multiplexer: copy the value of an input object into one of the N output
objects or onto the selected output objects
