DESCRIPTION
The EU-F-8z room regulator is intended to be used with external
controllers. It should be installed in heating zones. The regulator sends
current temperature and humidity readings from a given zone to the

thermostatic valves (opening them when the temperature is too low and
closing them when the pre-set temperature has been reached).
Current temperature is displayed on the main screen. In order to display
current humidity value, press the Menu button
