GENERAL DESCRIPTION OF THE THERMOSTAT

   This type switched-mode room thermostat is suitable to regulate
the overwhelming majority of boilers available in Europe. It can 
easily  be connected to any gas boiler or air conditioning device 
that has a  double wire connector for a room thermostat, regardless 
of whether it  has a 24 V or 230 V control circuit.

   Temperature can be measured more precisely as compared
to simple, conventional thermostats. In accordance with the
selected switching sensitivity, the thermostat will switch the boiler
or any other appliances on and off below and above the adjusted
temperature, respectively, and contributes to reduce energy costs
while maintaining comfort.
