Landis & Staefa Division Description of heating engineer settings 26.03.2001
4.32 Solar application
D.h.w. storage tank or buffer storage tank charging by solar collector.
The heat generated by the solar collector can be delivered either to the d.h.w. storage
tank or the buffer storage tank.
Setting range Unit Factory setting
0...2 - 0
Depending on the setting, either the d.h.w. or buffer storage tank is charged.
Entry:
0 No solar collector
1 Solar in d.h.w. storage tank
2 Solar in buffer storage tank
To ensure proper functioning, the location of the sensors in the storage tank must be
observed:
Solar for d.h.w. B3 at the top in the d.h.w. storage
tank
B31 at the bottom in the d.h.w.
storage tank
Solar for buffer storage tank B4 at the top in the buffer storage
tank
B41 at the bottom in the buffer
storage tank
4.33 Sensor input B8/B6
Selectable use of sensor.
Sensor input B8 / B6 is used for a flue gas temperature sensor or, in connection with
solar heating, for a sensor on the collector.
Setting range Unit Factory setting
0...2 – 0
0 Flue gas temperature sensor Pt 1000
1 Collector temperature sensor Ni 1000
2 Collector temperature sensor Pt 1000
