CAUTION

The booster heater permission schedule is used to restrict
or allow booster heater operation based on a weekly
program. Advice: In order to avoid unsuccessful
disinfection function, at least allow the booster heater (by
the weekly program) for minimum 4hours starting from the
scheduled start-up of disinfection. If the booster heater is
restricted during disinfection, this function will NOT be
successful and the applicable warning AH will be
generated.

INFORMATION

In case of error code AH and no interruption of the
disinfection function occurred due to domestic hot water
tapping, following actions are recommended:

▪ When the Reheat only or Schedule + reheat mode is

selected, it is recommended to program the start-up of
the disinfection function at least 4hours later than the
last expected large hot water tapping. This start-up can
be set by installer settings (disinfection function).

▪ When the Schedule only mode is selected, it is

recommended to program a Eco action 3 hours before
the scheduled start-up of the disinfection function to
preheat the tank.

INFORMATION

Risk of space heating capacity shortage for domestic hot
water tank without internal booster heater: In case of
frequent domestic hot water operation, frequent and long
space heating/cooling interruption will happen when
selecting the following:

Tank > Heat up mode > Reheat only.

INFORMATION

When the DHW tank mode is reheat, the risk for capacity
shortage and comfort problem is significant. In case of
frequent reheat operation, space heating/cooling function
is regularly interrupted.

4.5.3 Scheduled mode

In scheduled mode the DHWtank produces hot water corresponding
to a schedule. The best time to allow the tank to produce hot water is
at night, because the space heating demand is lower.

Example:

TtDHWtank temperature

t Time

4.5.5 To change the domestic hot water temperature

In Reheat only mode, you can use the room temperature setpoint
screen to read out and adjust the domestic hot water temperature.

1 Go to [5]: Tank.

You can read out the desired and actual room
temperature in the center of the setpoint screen.

2 Turn the right dial to adjust the domestic hot water

temperature.

In other modes, you can only view the setpoint screen but not modify
it. Instead, you can modify the settings for the Comfort setpoint [5.2],
Eco setpoint [5.3] and Reheat setpoint [5.4].

4.5.6 Using DHW powerful operation

About powerful operation

Powerful operation allows the domestic hot water to be heated by
the backup heater or booster heater. Use this mode on days when
there is more hot water usage than usual.

To check if powerful operation is active

If is displayed on the home screen, powerful operation is active.

Activate or deactivate Powerful operation as follows:

1 Go to [5.1]: Tank > Powerful operation

2 Turn powerful operation Off or On.

TtDHWtank temperature

t Time

▪ Initially, the DHW tank temperature is the same as the

temperature of the domestic water entering the DHW tank
(example: 15°C).

▪ At 00:00 the DHWtank is programmed to heat up the water to a

preset value (example: Comfort = 60°C).

▪ During the morning, you consume hot water and the DHW tank

temperature decreases.

▪ At 14:00 the DHWtank is programmed to heat up the water to a

preset value (example: Eco = 50°C). Hot water is available again.

▪ During the afternoon and evening, you consume hot water again

and the DHWtank temperature decreases again.

▪ At 00:00 the next day, the cycle repeats.

4.5.4 Scheduled + reheat mode

In scheduled + reheat mode, the domestic hot water control is the
same as in scheduled mode. However, when the DHW tank
temperature drops below a preset value (=reheat tank temperature –
hysteresis value; example: 35°C), the DHW tank heats up until it
reaches the reheat set point (example: 45°C). This ensures that a
minimum amount of hot water is available at all times.

Example:

EHBH/X04+08DA + EHVH/X04+08S18+23DA
Daikin Altherma – Low temperature split
4P495250-1 – 2017.12

Usage example: You immediately need more hot water

You are in the following situation:

▪ You already consumed most of your domestic hot water.

▪ You cannot wait for the next scheduled action to heat up the

domestic hot water tank.

Then you can activate powerful operation. The domestic hot water
tank will start heating up the water to the Comfort temperature.

INFORMATION

When powerful operation is active, the risk of space
heating/cooling and capacity shortage comfort problems is
significant. In case of frequent domestic hot water
operation, frequent and long space heating/cooling
interruptions will happen.

5 Energy saving tips

▪ Use a weekly schedule for your normal space heating or cooling

needs. If necessary, you can easily deviate from the schedule:

▪ For shorter periods: You can overrule the scheduled room

temperature until the next scheduled action. Example: When
you have a party, or when you are leaving for a couple of hours.

▪ For longer periods: You can use the holiday mode.

Tips about leaving water temperature

▪ In heating mode, a lower desired leaving water temperature

results in lower energy consumption and better performance. In
cooling, the opposite is valid.

▪ Set the desired leaving water temperature in accordance with the

heat emitter type. Example: Underfloor heating is designed for
lower leaving water temperature than radiators and heat pump
convectors.

Tips about DHWtank temperature

▪ Use a weekly schedule for your normal domestic hot water needs

(only in scheduled mode).

▪ Program to heat up the DHW tank to a preset value (Storage

comfort = higher DHW tank temperature) during the night,
because then space heating demand is lower.

▪ If heating up the DHW tank once at night is not sufficient,

program to additionally heat up the DHWtank to a preset value
(Storage eco = lower DHWtank temperature) during the day.

▪ Make sure the desired DHWtank temperature is NOT too high.

Example: After installation, lower the DHWtank temperature daily
by 1°C and check if you still have enough hot water.

▪ Program to turn ON the domestic hot water pump only during

periods of the day when instant hot water is necessary. Example:
In the morning and evening.

6 Maintenance and service

6.1 Overview: Maintenance and service

The installer has to perform a yearly maintenance. You can find the
contact/helpdesk number via the user interface.

As enduser, you have to:

▪ Keep the area around the unit clean.

▪ Keep the user interface clean with a soft damp cloth. Do NOT use

any detergents.

▪ Regularly check if the water pressure is above 1bar.

Refrigerant

This product contains fluorinated greenhouse gases. Do NOT vent
gases into the atmosphere.

Refrigerant type: R32

Global warming potential (GWP) value: 675

Tips about room temperature

▪ Make sure the desired room temperature is NEVER too high (in

heating mode) or too low (in cooling mode), but ALWAYS
according to your actual needs. Each saved degree can save up
to 6% of heating/cooling costs.

▪ Do NOT increase the desired room temperature to speed up

space heating. The space will NOT heat up faster.

▪ When your system layout contains slow heat emitters (example:

under floor heating), avoid large fluctuation of the desired room
temperature and do NOT let the room temperature drop too low. It
will take more time and energy to heat up the room again.

User reference guide

NOTICE

In Europe, the greenhouse gas emissions of the total
refrigerant charge in the system (expressed as tonnes
CO2-equivalent) is used to determine the maintenance
intervals. Follow the applicable legislation.

Formula to calculate the greenhouse gas emissions:

GWP value of the refrigerant × Total refrigerant charge [in
kg] / 1000

Please contact your installer for more information.

7 Troubleshooting

7.1 To display the help text in case of a malfunction

In case of a malfunction, the following will appear on the home
screen depending on the severity:

7.3 Symptom: You are feeling too cold (hot) in your living room

Possible cause Corrective action

The desired room temperature is
too low (high).

The desired room temperature
cannot be reached.

Increase (decrease) the desired
room temperature.

If the problem recurs daily, do
one of the following:

▪ Increase (decrease) the room

temperature preset value.

▪ Adjust the room temperature

schedule.

Increase the desired leaving
water temperature in accordance
with the heat emitter type.

7.4 Symptom: The water at the tap is too cold

Possible cause Corrective action

You ran out of domestic hot
water because of unusual high
consumption.

The desired DHWtank
temperature is too low.

If you immediately need domestic
hot water, activate the DHW tank
Powerful operation. However,
this consumes extra energy.

If you can wait, overrule
(increase) the active or next
scheduled desired temperature
so that more hot water will be
produced exceptionally.

If the problems recurs daily, do
one of the following:

▪ Increase the DHW tank

temperature preset value.

▪ Adjust the DHW tank

temperature schedule.
Example: Program to
additionally heat up the
DHW tank to a preset value
(Eco setpoint = lower tank
temperature) during the day.

7.5 Symptom: Heat pump failure

When the heat pump fails to operate, the backup heater and/or
booster heater can serve as an emergency heater and either
automatically or non-automatically take over the heat load.

▪ When auto emergency is set to Automatic and a heat pump failure

occurs:

▪ For EHVH/X: The backup heater will automatically take over the

heat load and domestic hot water production

▪ For EHBH/X: The backup heater will automatically take over the

heat load, and the booster heater in the optional tank will
automatically take over the domestic hot water production.

▪ When auto emergency is set to Manual and a heat pump failure

occurs, the domestic hot water and space heating operation will
stop and need to be recovered manually via the user interface. To
recover operation manually, go to the Malfunctioning main menu
screen, where the user interface will then ask you to confirm
whether the backup heater and/or booster heater can take over
the heat load or not.

When the heat pump fails, or will appear on the user
interface.
