FOR STARTERS
OUMAN EH-203
Ouman EH-203 is a multifunctional heating controller which is
adaptable to many different types of heating systems. Ouman EH-203
has the ability to control two heating circuits and one hot water
control circuit simultaneously. Your controller's display changes
depending on the connections and selected functions that are in use.
All the different functions are presented in this user manual. In the
beginning we present the basic principles for using the controller.

Remote control options:
Most of EH-203's user level functions can also be
carried out via GSM phone text messages.
Remote control via a GSM phone
Text message use is illustrated on page 20.
Web based user interface
Ouman controllers can also be controlled and monitored
via an inexpensive web user interface. A web scanner is
easy to use and can illustrate remote control and
monitoring of even large Ouman control systems
regardless of the time and place.
