Landis & Staefa Division Description of heating engineer settings 26.03.2001
Solar / Puffer
4.73 Temperature differential solar ON (TSdEin)
Collector pump’s switch-on point.
The setting defines the switch-on threshold for the collector pump.
Setting range Unit Factory setting
TSdAus...40 °C (K) 20
If the differential of collector temperature and storage tank temperature exceeds
temperature differential (TsdEin), the collector pump will be activated.
4.74 Temperature differential solar OFF (TSdAus)
Collector pump’s switch-off point.
The setting defines the switch-off threshold for the collector pump.
Setting range Unit Factory setting
0...TSdOn °C (K) 8
If the differential of collector temperature and storage tank temperature is smaller than
temperature differential (TsdAus), the collector pump will be deactivated.
