When measuring the load on relays with a my-PV Meter, it is essential to follow the
corresponding wiring diagram!
The relay is switched on for the first time when a surplus level of 3kW is exceeded with the
AC•THOR
or 9kW with the
AC•THOR
9s. As soon as a measured value of the load is available,
it is taken into account as a switching threshold in further operation!
If the nominal power at the switched load is reduced at a later point in time (e.g. due to a
modification of the system), the switching threshold must be changed once to "Load on relay".
Afterwards, the setting can be changed back to "Load measurement at relay with my-PV
Meter". See chapter "Special setting options in the web interface".
Hot water 1 temperatures
Adjustable is the maximum permitted temperature to be reached at the my-PV temperature sensor
(factory setting = 60 °C). This has nothing to do with a bimetal thermostat which may be installed!
If the cut out temperature of an immersion heating element with a bimetal thermostat is set
too low, the AC•THOR may possibly be unable to reach the desired temperature!
If the optional automatic temperature boost backup is shown "On" in the window on the right
(factory setting "Off"), a minimum temperature can then be set (factory setting 50 °C).
Automatic temperature boost backup "On":
With both immersion heaters
, the AC•THOR can assure a minimum temperature at the my
-PV
temperature sensor. These are supplied with maximum power.
Hot water 1 min switching times
This setting can be selected when the temperature boost backup is "On" under Hot water 1
temperatures".
There are two time windows available to maintain the minimum temperature on the my-PV
temperature sensor. Start and finish can each be defined at full hours. Factory settings suggest
switching times of 5 to 11 pm and 5 to 7 am.
TIP: Restrict the times when the minimum temperature has to be maintained to
mornings and evenings, to increase your own PV consumption through the day!
Start hour and stop hour refer to the same calendar day. If a time window is defined over
midnight, hot water backup will not start!
