Terms
The complete product range of flexible and scalable control solutions, standardized
up to and including freely programmable solutions.
Specialized for HVAC applications.
The Synchronisation of the mechanical position and the internal position control will
be performed (after manual operation).
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 [mm]: Characteristic for matching parts of the piping system.
The fail safe function ensures that the actuator is driven to a defined end position
also in the event of a power failure. In normal situations, dampers are shut or
valves closed, thus cutting off the medium flow.
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
100
) at a differential pressure of 100 kPa (1 bar).
Light emitting diode.
The actuator stem lifts off the valve stem slightly (0.2 mm), so that the valve closed
securely. If the valve opens again, this idle stroke has to be overcome, before the
valve really opens (valve characteristic has an effect).
Open communications protocol (client/server architecture), transmits data as binary
data.
RTU: Remote Terminal Unit.
