T4DHWMAX
sets the ambient temperature above which the heat
pump will not operate in DHW mode. The highest value that
T4DHWMAX
can take is 43°C, which is the DHW mode upper ambient
temperature operating limit of the heat pump.
T4DHWMIN
sets the ambient temperature below which the heat
pump will not operate in DHW mode. The lowest value that
T4DHWMIN
can take is -25°C, which is the DHW mode lower ambient
temperature operating limit of the heat pump.
t_INTERVAL_DHW
sets the DHW mode compressor re-start delay. When the compressor stops running, it will not re-start
until at least
