thermostat
Operating principle
The thermostat is designed to control water
circulation pump C.O. The task of the thermostat
is switching on the pump if the temperature
exceeds required value, and disable it when the
boiler cools down (due
unnecessary operation of the pump, which saves
electric energy (savings, depending on the degree
of utilization of the boiler, reaching up to 60%) and
extend pump life. This increases the reliability
and decrease costs associated with the operation.
The temperature pump start is controlled
potentiometer (range 10˚C-90˚C). The pump stops
when the actual temperature drops by 5˚C below
the temperature set point (potentiometer set).
Start and stop the pump after about 30 seconds.
Prevents the constant switching of the pump in
case of rapid changes temperature.
The thermostat has two switches. The first one is
used to switching on the thermostat (this is
indicated by the glowing red LED's). The second is
used for manual pump operation (indicated by
green). Green LED indicates the operation of the
pump with automatic control of pump. The
regulator has a protection in the form of reusable
polymer fuse (inside the housing of the plate).
