EV02F
ELECTRONIC CONTROL UNIT WITH QUARTZ CLOCK
for the thermoregulation of heating systems by proportional integral
control of mixing valves or by ON-OFF control of burners, daily programming.
EV02F ELECTRONIC CONTROL UNIT
GENERAL FEATURES
- Electronic control unit for the thermoregulation of
heating systems.
- The devices regulates the delivery water temperature
of the system as a function of the outside temperature
and of the required ambient temperature. Regulation
is performed by direct control of the burner or by
proportional-time control of a 3- or 4-way motor-
operated mixing valve.
- The outside and delivery temperatures are

detected by special probes provided for the purpose.
Temperature values are sent to the control unit
which according to the set programming determines
the delivery water temperature value to be sent to
the system to keep the set ambient temperature
constant.
- The control unit is fitted with: quartz clock for daily
programming of ON/OFF times and manual/automat-
ic mode switching. Potentiometer to select system
heating curve with slope adjustable from 0.25 to 4.5.
