Terms

The complete product range of flexible and scalable control solutions, standardized
up to and including freely programmable solutions.
Specialized for HVAC applications.
A DIL switch shows the switching choices in the form of a place value system (dual
in line) in relation to basis 2 (on and off).
Nominal size: Characteristic for matching parts of the piping system.
Forced control serves for overriding automatic mode and is implemented in the
structure.
A HEX switch shows the switching choices in the form of a place value system
(hexadecimal system) in relation to basis 16 (0...9 and A...F).
Unit of pressure: 100 kPa = 1 bar = 10 mWS.
Nominal flow rate: Nominal flow rate of cold water (5...30 °C) through the fully
open valve (H ) at a differential pressure of 100 kPa (1 bar).
100
Light emitting diode.
Open communications protocol (client/server architecture), transmits data as binary
data.
RTU: Remote Terminal Unit.
PN class: Characteristic relating to the combination of mechanical und dimensional
properties of a component in the piping system.
Signal used to acquire the position, fed back via an input.
Refer "fail safe function".
