Description of elements and LEDs
The electronic thermostat PT02 is used to switch circulating pumps depending on the set
temperature and hysteresis (
Fig.4b
( ).
The advantage is the adjustable hysteresis (2 °C to 20 °C), easy adjustment of the
control temperature and easy installation directly on the surface of the pipe. In addition,
it contains anti-scale protection. Its mounting is carried out by a tension spring. Controls
and connection terminals are secured against unwanted manipulation with the lock screw.
