Specific settings for operating mode M8
Frequency
The frequency range in which the adjustable power can be linearly fed can be altered. As lower limit
(no power) and upper limit (maximum power) a range between 45 and 65 Hz is available. The
factory settings are 50 Hz and 51 Hz.
The frequency range must be at least 1.0 Hz!
Maximum power
The input of maximum power of the heating load is extremely important for this operating mode.
This is why this setting possibility appears here in second place again, in addition to its normal
position in the settings. See "General Settings" for details.
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") or the relay output has been selected, a minimum temperature can then be
set (factory setting 50 °C). It cannot be set higher than the maximum temperature.
Automatic temperature boost backup "On":
The AC•THOR can ensure a minimum temperature at the my-PV temperature sensor through the
immersion heating element connected. This is supplied with maximum power.
Relay output:
Alternatively, the minimum temperature can be maintained by enabling an external heat source.
Enablement is by means of a potential-free contact. For details of wiring the potential-free contacts,
please refer to the assembly instructions in the chapter "Connections".
