Daikin Altherma hybrid heat pump
4P355632-1E – 2020.10
Possible cause Corrective action
The desired room temperature cannot
be reached.
Increase the desired leaving water
temperature in accordance with the
heat emitter type. See "4.4.6Room
thermostat control - Using the leaving
water temperature home pages"[422].
The weather-dependent curve is set
incorrectly.
Adjust the weather-dependent curve.
See "4.8Weather dependent
operation"[443].
9.5 Symptom: The water at the tap is too cold
Possible cause Corrective action
Your tank ran out of domestic hot water
because of unusual high consumption.
If you immediately need domestic hot
water, activate the DHWtank booster
mode. However, this consumes extra
energy. See "Using the DHWtank
booster mode"[430].
If you can wait, overrule (increase) the
active or next scheduled desired
temperature so that more hot water
will be produced exceptionally. See "To
read out and overrule the active or next
scheduled desired temperature (in
scheduled mode or scheduled + reheat
mode)"[429].
If the problems recurs daily, do one of
the following:
▪ Increase the DHW tank temperature
preset value. See "4.7.1 Using preset
values"[438].
▪ Adjust the DHW tank temperature
schedule. Example: Program to
additionally heat up the DHWtank to
a preset value (Storage eco =
lower tank temperature) during the
day. See "4.7.2 Using and
programming schedules" [4 39] and
"4.7.3Schedules: Example"[440].
The desired DHWtank temperature is
too low.
The instant DHW temperature is too
low. (Only applicable when no tank is
installed).
Increase the instant DHW set point
temperature. See "To adjust the instant
DHW temperature"[427].
9.6 Symptom: Heat pump failure
When the heat pump fails to operate, the gas boiler can serve as an emergency
back-up heater and either automatically or non-automatically take over the entire
heat load.
