OPERATION MANUAL

Installation

Python Version 2.7 must be installed to use pySoftcheck. The pySerial package is also required

(Huber Runtime) to enable data exchange via the serial interface. See installation instructions for

each platform (see below).

1.1 Windows

Before you can install pySoftcheck, you must install the “Huber Runtime” package. You can download

it from our homepage. This package installs all the dependencies such as Python and pySerial.

PySoftcheck can be installed once the installation of “Huber Runtime” is complete. To do so, please

run the appropriate installer.

1.2 Linux

Please contact us.

Application

pySoftcheck is an application that permits remote control of the Huber thermostats via an interface.

The presented module pySoftcheck is written in Python. The end user therefore can use the entire

Python environment for developing custom scripts. Another advantage of Python is that it is plat-

form independent. pySoftcheck therefore should run on any platform that supports Python and

pySerial.

A good introduction to the scripting language Python can be found in Galileo Computing.
