4.7 Domestic hot water control

4.7.1 About domestic hot water control

Depending on the DHW tank mode (installer setting), you use a
different domestic hot water control:

▪ Reheat only

▪ Schedule + reheat

▪ Schedule only

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 an Eco action 3hours before
the scheduled start-up of the disinfection function to
preheat the tank.

When weather-dependent operation is used for the tank, the tank
temperature is determined automatically by the outdoor temperature.
For more information, see "4.9Weather-dependent curve"[424].

To determine which domestic hot water mode you are using
(method 1)

Check the installer settings table filled in by the installer.

To determine which domestic hot water mode you are using
(method 2)

1 Go to [5]: Tank.

2 Check which items are displayed:

If… is displayed Then the DHWtank mode =…

Only [5.1] Powerful
operation

All items except [5.4]
Reheat setpoint are
displayed

All items including [5.4]
Reheat setpoint are
displayed

4.7.2 Reheat mode

In reheat mode the DHW tank continuously heats up to the
temperature shown on the home screen (example: 50°C) when the
temperature drops below a certain value.

Reheat only

Schedule only

Schedule + reheat

TtDHWtank temperature

t Time

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.

4.7.3 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

▪ 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.

4.7.4 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.

When weather-dependent operation is used for the tank, the tank
temperature is determined automatically by the outdoor temperature.
For more information, see "4.9Weather-dependent curve"[424].

4.7.6 Using DHW powerful operation

About powerful operation

Powerful operation allows the domestic hot water to be heated by
the backup 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.

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.

4.9 Weather-dependent curve

4.9.1 What is a weather-dependent curve?

Weather-dependent operation

The unit operates 'weather dependent' if the desired leaving water or
tank temperature is determined automatically by the outdoor
temperature. It therefore is connected to a temperature sensor on
the North wall of the building. If the outdoor temperature drops or
rises, the unit compensates instantly. Thus, the unit does not have to
wait for feedback by the thermostat to increase or decrease the
temperature of the leaving water or tank. Because it reacts more
quickly, it prevents high rises and drops of the indoor temperature
and water temperature at tap points.

Advantage

Weather-dependent operation reduces energy consumption.

Weather-dependent curve

To be able to compensate for differences in temperature, the unit
relies on its weather-dependent curve. This curve defines how much
the temperature of the tank or leaving water must be at different
outdoor temperatures. Because the slope of the curve depends on
local circumstances such as climate and the insulation of the house,
the curve can be adjusted by an installer or user.

Types of weather-dependent curve

There are 2 types of weather-dependent curves:

▪ 2-points curve

▪ Slope-offset curve

Which type of curve you use to make adjustments, depends on your
personal preference. See "4.9.4 Using weather-dependent

curves"[425].

Availability

The weather-dependent curve is available for:

▪ Main zone - Heating

▪ Main zone - Cooling

▪ Additional zone - Heating

▪ Additional zone - Cooling

▪ Tank

INFORMATION

To operate weather dependent, correctly configure the
setpoint of the main zone, additional zone or tank. See

"4.9.4Using weather-dependent curves"[425].

Item Description

a Selected weather dependent zone:

▪ : Main zone or additional zone heating

Y1, Y2 Examples of desired tank temperature or leaving water

temperature. The icon corresponds to the heat emitter
for that zone:

▪ : Underfloor heating

▪ : Fan coil unit

▪ : Radiator

▪ : Domestic hot water tank

Possible actions on this screen

Go through the temperatures.

Change the temperature.

Go to the next temperature.

Confirm changes and proceed.

4.9.3 Slope-offset curve

Slope and offset

Define the weather-dependent curve by its slope and offset:

▪ Change the slope to differently increase or decrease the

temperature of the leaving water for different ambient
temperatures. For example, if leaving water temperature is in
general fine but at low ambient temperatures too cold, raise the
slope so that leaving water temperature is heated increasingly
more at decreasingly lower ambient temperatures.

▪ Change the offset to equally increase or decrease the

temperature of the leaving water for different ambient
temperatures. For example, if leaving water temperature is always
a bit too cold at different ambient temperatures, shift the offset up
to equally increase the leaving water temperature for all ambient
temperatures.

Examples

Weather-dependent curve when slope is selected:

4.9.2 2-points curve

Define the weather-dependent curve with these two setpoints:

▪ Setpoint (X1, Y2)

▪ Setpoint (X2, Y1)

5 Energy saving tips

5 Energy saving tips

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.

▪ 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 (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
(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.

on the screen.

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. See

"4.7.6Using DHW powerful
operation"[419].

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

▪ Increase the DHW tank

temperature preset value. See

"4.8.1 Using preset
values"[420].

▪ 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.
See "4.8.3 Using and

programming schedules" [421]

and "4.8.4 Schedule screen:

Example"[421].

7.2 To check the malfunction history

Conditions: The user permission level is set to advanced end user.

1 Go to [8.2]: Information > Malfunction history.

You see a list of the most recent malfunctions.

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.

The weather-dependent curve is
set incorrectly.

Increase (decrease) the desired
room temperature. See "4.6.4To

change the desired room

water temperature in accordance
with the heat emitter type. See

"4.6.5To change the desired
leaving water temperature"[417].

Adjust the weather-dependent
curve. See "4.9Weather-

dependent curve"[424].

7.5 Symptom: Heat pump failure

When the heat pump fails to operate, the backup heater can serve
as an emergency heater. It then takes over the heat load either
automatically or by manual interaction.

▪ When Emergency is set to Automatic and a heat pump failure

occurs, the backup heater automatically takes over the domestic
hot water production and space heating.

▪ When Emergency is set to Manual and a heat pump failure

occurs, the domestic hot water heating and space heating stops.
To manually recover it via the user interface, go to the
Malfunctioning main menu screen and confirm whether the
backup heater can take over the heat load or not.

▪ Alternatively, when Emergency is set to:

▪ auto SH reduced/DHW on, space heating is reduced but

domestic hot water is still available.

▪ auto SH reduced/DHW off, space heating is reduced and

domestic hot water is NOT available.

▪ auto SH normal/DHW off, space heating operates as

normally but domestic hot water is NOT available.
Similarly as in Manual mode, the unit can take the full load with
the backup heater if the user activates this via the
Malfunctioning main menu screen.

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

Possible cause Corrective action

Heat pump is damaged. See "7.1To display the help text

in case of a malfunction"[430].

INFORMATION

When the backup heater takes over the heat load,
electricity consumption will be considerably higher.
