EU-402n

The EU-402n temperature regulator is intended for the operation of the solar collector installation. This device controls the operation of the main (collector) pump on the basis of temperature measurement on the collector and in the accumulation tank. Optionally, it is possible to connect an additional device: a circulating pump, an electric heater or feed the signal to the CH boiler in order to fire it up.
