EGULUS - SRS 3 Controller - www.re
ulus.
Settings menu 5
D 5 - Settings
The necessary basic settings required for the control
function are made in menu „5. Settings”.
The menu is closed by pressing „esc” or selecting
„Exit settings”.
Various settings can be made depending on the selection of hydraulic variant 1-20. An overview of
the variants is shown in Table 5.14.
Often more conditions must be met simultaneously for the relay to switch, as it is obvious from the
Table 5.14. (E.g. ΔT between a collector and storage tank, Min./max. collector temperature and max.
storage tank temperature). When only one condition is met, the relay does not switch (e.g. ΔT might
be reached but the collector temperature is still below T1min).
D 5.1 - Tmin S1
menu 5.x = sensor S1 switch-on temperature
If this value is exceeded at sensor S1 and the other conditions as in Table 5.14 are also met, then the
controller switches the associated pump and/or valve on. If the temperature at sensor S1 drops below this
value by 5 °C, then the pump and/or the valve are switched off again.
Setting range: 0-99 °C / default setting: 20 °C
D 5.2 - Tmin S2 menu 5.x = sensor S2 switch-on temperature
If this value is exceeded at sensor S2 and the other conditions as in Table 5.14 are also met, then the
controller switches the associated pump and/or valve on. If the temperature at sensor S2 drops below this
value by 5 °C, then the pump and/or the valve are switched off again.
Setting range: 0-99 °C / default setting: 40 °C
D 5.3 - Tmin S3 menu 5.x = sensor S3 switch-on temperature
If this value is exceeded at sensor S3 and the other conditions as in Table 5.14 are also met, then the
controller switches the associated pump and/or valve on. If the temperature at sensor S3 drops below this
value by 5 °C, then the pump and/or the valve are switched off again.
Setting range: 0-99 °C / default setting: 20 °C
D 5.4 - Tmax S2 menu 5.x = sensor S2 switch-off temperature
If this value is exceeded at sensor S2, then the controller switches the associated pump and/or valve off. If
sensor S2 temperature falls below this value again and the other conditions as in Table 5.14 are also met, then
the controller switches the pump and/or valve on again.
Setting range: 0-99 °C / default setting: 60 °C
Temperature values which are set too high will allow higher solar heat accumulation but it shall be
checked that all system components are resistant to high temperature and scalding protection is
provided. Regulus solar systems are safe for heating water up to 95 °C.
D 5.5 Tmax S3 menu 5.x = sensor S3 switch-off temperature
If this value is exceeded at sensor S3, then the controller switches the associated pump and/or valve off. If
sensor S3 temperature falls below this value again and the other conditions as in Table 5.14 are also met, then
the controller switches the pump and/or valve on again.
Setting range: 0°-99 °C/default setting: 60 °C (in hydraulic variants with S3 default: Off)
Temperature values which are set too high will allow higher solar heat accumulation but it shall be
checked that all system components are resistant to high temperature and scalding protection is
provided. Regulus solar systems are safe for heating water up to 95 °C.
