Directly patch the parameters in the PPSS entry that triggeres the OP
heater once per minute.
Due to the nonlinearity of the regulator we can alway roughly assume we
heat with DC=70%. We need to adjust the setpoint with a correspondig
offset. This offset depends on the gain. The default gain is
`shift=0`. The DC will be ADC-setpoint. A shift of 1, 2, or 3 will
reduce the DC by a power of two, i.e.,
DC = (ADC - setpoint) >> shift
This patch keeps shift=0.
The target temperatures are
HET/EPT1: -6.0°C
HET/EPT2: -0.5°C
