In HEAT MODE SETTING the following parameters should be set.
HEAT MODE enables or disables heating mode.
t_T4_FRESH_H sets the refresh time of heating mode climate temperature curve.
T4HMAX sets the ambient temperature above which the heat pump will not
operate in heating mode. The highest value that T4HMAX can take is 35°C,
which is the heating mode upper ambient temperature operating limit of the
heat pump. Refer to Figure 3-7.15.
T4HMIN sets the ambient temperature below which the heat pump will not operate in heating mode. The lowest value
that T4CMIN can take is -25°C, which is the heating mode lower ambient temperature operating limit of the heat pump.
Refer to Figure 3-7.16.
dT1SH sets the temperature difference between the heat pump leaving water
temperature (T1) and the heat pump leaving water set temperature (T1S)
above which the heat pump provides heated water to the space heating
terminals.
