Application
The ST-401N type temperature regulator is intended for the operation of solar collectors for various
system configurations. This device controls the operation of collector pumps (or a pump and a valve)
on the basis of the measurement of the solar panel temperatures and the accumulation tank (two
tanks) temperature. There is an option to connect an additional device: circulation pump, electric heater
or feeding the signal to the CH boiler in order to fire it up.
It is possible to control the circulation pump and feed the firing-up signal to the CH boiler directly
from the controller, while an additional signal relay is necessary to control the heater.
