CONTROLLER REGULATOR THREE PUMPS ST-427i TECH

The ST-427i regulator is designed to control the operation of three pumps. The task of the regulator is to switch on the pumps if the temperature exceeds the threshold switching value, and turn it off if the boiler cools down (due to extinguishing). For the second pump, in addition to the switching temperature, the user sets the set temperature to which the pump will work. It is possible to freely set the priorities of pump operation.
