INFORMATION
Settings [9.3.3] and [9.3.5] are linked. Changing one setting influences the other. If
you change one, check if the other is still as expected.
INFORMATION
During normal operation, the capacity of the second step of the backup heater at
nominal voltage is equal to [6‑03]+[6‑04].
INFORMATION
If [4‑0A]=3 and emergency mode is active, the power usage of the backup heater is
maximal and equal to 2×[6‑03]+[6‑04].
INFORMATION
Only for systems with integrated domestic hot water tank: If the storage
temperature setpoint is higher than 50°C, Daikin recommends NOT to disable the
backup heater second step because it will have a big impact on the required time for
the unit to heat up the domestic hot water tank.
