For AC
•
THOR 9s this number has four digits. The first digit shows the status of the switch output (0
or 1), the second digit whether Out-3 is switched (0 or 1), the third digit whether Out-2 is switched
(0 or 1) and the fourth digit shows the output that is currently supplied by the power stage (1, 2 or
3).
See chapter "General settings" for general unit settings, also chapter "Operating modes" for settings
specific to the respective operating mode.
After activation, brief information on the current view appears on the display. In the web interface the
button leads to the online Operation Manual which corresponds to the firmware version installed.
You will find wiring diagrams for the respective operating modes and for wiring three-phase
heating elements in the assembly instructions suppli
ed with the AC•THOR, as well
as in the
latest version at any time on www.my-pv.com.
AC•THOR: Hot water with
a single-phase immersion heater
AC•THOR 9s: Hot water with a three
-phase immersion heater or with 3 single-phase immersion
heaters
TIP for AC•THOR:
A single-phase heating element does not necessarily have to have 3kW power. Of
course, smaller outputs such as 2kW are also possible!
TIP for AC•THOR 9s:
A three-phase heating element does not necessarily have to have 9kW power.
Smaller outputs such as 4.5kW, 6kW or 7.5kW are also possible!
Likewise, three single-phase elements can have a power of less than 3kW!
In this operating mode, an electric heating element is supplied linearly with excess PV energy. It can
be fitted with a bimetal thermostat to switch off when the temperature for which it is set is reached.
Otherwise the my-PV temperature sensor is to be used.
