5.4.5 Solar
Function (ECO-S1):
This is used in simple solar systems with a single control
circuit to heat the utility water in the solar utility water
heater (Art. No: WSS-___). The ECO-S1 controller is an
additional component for the ECO-B1(2) controller for the
utility water heater. When the solar collector is hotter
than the utility water at the bottom, it is heated up by the
solar collector.
Operating modes
-
Off:
Pump off; valve shut.
-
Automatic:
Automatic heating of the solar utility water heater by
means of difference-based control.
-
Manual:
Emergency operation: Pump on.

Function (ECO-S3):
(Only possible with accumulator option)
This is used in large solar systems to heat the utility water
in a solar utility water heater (Art. No: WSS-4050) and
for supplying heat to the heat accumulator by means of a
triple control circuit. The first circuit is for heating the do-
mestic water, the second circuit is for heating the heat
accumulator at the back/bottom and the third circuit is for
heating the heat accumulator at the front/top. The heating
storage unit is heated up by an externally situated plate-
type heat exchanger. On switchover from utility water
heater to heat accumulator, the secondary pump is
switched on, which is then in operation with the solar
pump. For optimised functioning, the flow rate in the sec-
ondary circuit has to be adapted to the primary circuit
(e.g. with flow rate gauges in the primary and secondary
circuits).
Operating modes
-
Off:
Pump off; valve shut
-
Automatic:
Automatic heating of the solar utility water heater and
of the accumulator by means of difference-based con-
trol.
-
Manual:
Emergency operation
Solar pump and secondary
pump on; valves are not controlled (emergency opera-
tion).

(02) Temperature of utility water; maximum (65°C)
The maximum temperature of the utility water with solar
heating.
(03) Priority to utility water (optimised)
- Optimised:
Priority to loading utility water, but if the solar output is
not sufficient to finish loading the utility water heater,
there is a switchover to solar heated heating. If the solar
output rises (cyclical examination) so much that heating of
utility water is possible, there is again a switchover to so-
lar heated utility water.
- Absolute:
Loading utility water has absolute priority, i.e. solar heated
heating is not allowed until the utility water heater has
been
completely
loaded.
- No:
Solar heating of utility water/Heating according to the
temperature difference between the collector and the util-
ity water at the bottom or the collector and the storage
unit at the bottom.
(04) Collector/Utility water; set difference (10°C)
The temperature difference between the collector and the
utility water at the bottom for solar utility water heating.
(05) Collector/Storage unit; set difference (15°C)
The temperature difference between the collector and the
storage unit at the bottom for solar heating system heat-
ing.
