6.4.7 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 util-
ity water in a solar utility water heater (Art. No:
WSS-___) and for supplying heat to the heat ac-
cumulator by means of a triple control circuit. The
first circuit is for heating the domestic water, the
second circuit is for heating the heat accumulator
at the back/bottom and the third circuit is for heat-
ing 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 func-
tioning, the flow rate in the secondary circuit has
to be adapted to the primary circuit (e.g. with flow
rate gauges in the primary and secondary cir-
cuits).
Operating modes
-
Off:
Pump off; valve shut
-
Automatic:
Automatic heating of the solar utility water
heater and of the accumulator by means of dif-
ference-based control.
-
Manual:
Emergency operation
Æ
Solar pump and sec-
ondary pump on; valves are not controlled
(emergency operation).
(mask number) parameter (factory setting)
(01) Operating mode (automatic)
Select operating mode
(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 out-
put is not sufficient to finish loading the utility wa-
ter heater, there is a switchover to solar heated
heating. If the solar output rises (cyclical examina-
tion) so much that heating of utility water is possi-
ble, there is again a switchover to solar heated
utility water.
- Absolute:
Loading utility water has absolute priority, i.e. so-
lar 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 utility 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 heat-
ing system heating.
