Controller for Solar Domestic Water Heater [Art. No. ECO-S1 / 7387818]
Application for simple solar systems as a single-circuit controller for
heating the domestic water in the solar domestic water heater (Art. No.:
WSS-...). The ECO-S1 controller is an add-on module for the ECO-B1
domestic water heater controller (2). If the solar collector is warmer than
the domestic water below, the water is heated up by the solar collector
(adjustable temperature difference 2–20° C).
Further details:
Post-flow period of the solar pump, no/yes: 0-120 sec., adjustable
-
according to length of line
Maximum domestic water temperature (adjustable: 20-90°C)
-
-
Safety: disconnection of the solar pump at a collector temperature of
140°C; reconnection at 120°C
Scope of delivery:
Pushbutton for solar system
-
Collector sensor PT-1000
-
-
Domestic water sensor QAZ 21.5220
Controller output for solar pump (1)
-
Note:
Only possible in combination with domestic water heater control (ECO-B1
or ECO-B2).
Solar/domestic water and heating controller [Art.-No. ECO-S3 / 7387786]
For use in large-scale solar facilities to heat the domestic water in a solar domestic water heater (Art. No: WSS-...) and to
supply heat to the heat accumulator in the form of a triple control circuit heating system. 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
heating the heat accumulator at the front/top. The heat accumulator is heated by an externally situated plate heat
exchanger. When there is a changeover from the domestic water heater to the heat accumulator, the secondary pump is
switched on, which is then operated with the solar pump. For optimised functioning, 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 circuits).
The following temperature differences are freely adjustable:
Temperature difference of collector/domestic water: 2-20°C
Temperature difference of collector/accumulator, rear/bottom: 2-20°C
Further details:
Post-flow period of the solar pump, no/yes: 0-120 sec., adjustable according to length of line

Disconnection safeguard:
-
Optimised domestic water priority (option of either absolute domestic water priority or none at all)
-
Stratified accumulator loading according to the accumulator temperatures, via valve/accumulator, back/accumulator
front (4)
