Function ECO-S1
Application for simple solar systems as single control circuit for heating the utility water
in the solar utility water heater.
The ECO-S1 controller is an add-on module for the utility water heater controller ECO-
B1(2).
If the solar collector is warmer than the lower utility water then the utility water will be
heated by the solar collector.

Function ECO-S3
Application for larger solar system for heating the utility water in the solar utility water
heater and for heat input to the heat storage tank as a triple control circuit heating
system.
The first circuit serves to heat the utility water, the second circuit serves to heat the heat
storage tank back/bottom and the third circuit serves to heat the heat storage tank
front/top.
The heating of the heat storage tank is carried out with an exterior plate heat
exchanger. The secondary pump is switched on with the change over from utility water
heater to heat storage tank. This pump is then in operation with the solar pump.
For optimal function the flow through the secondary circuit must be matched to the
primary circuit, e.g. with a flowmeter in the primary and secondary circuits.
