4.5.1 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
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 4hours 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
4hours 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.
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.

In scheduled + reheat mode, the domestic hot water control is the same as in
scheduled mode. However, when the DHWtank temperature drops below a preset
value (=reheat tank temperature – hysteresis value; example: 35°C), the DHWtank
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.

4.8 Weather-dependent curve
4.8.1 What is a weather-dependent curve?
1 Program 3 room temperature schedules and give them appropriate names.
Example: EarlyShift, DayShift and LateShift
2 Select the schedule that you currently want to use.
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 "4.8.4Using weather-dependent curves"[441].
Availability
The weather-dependent curve is available for:
▪ Main zone - Heating
▪ Main zone - Cooling
▪ Additional zone - Heating
User reference guide

▪ Additional zone - Cooling
▪ Tank (only available to installers)
INFORMATION
To operate weather dependent, correctly configure the setpoint of the main zone,
additional zone or tank. See "4.8.4Using weather-dependent curves"[441].

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.

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/decrease the desired room temperature to speed up space
heating/cooling. The space will NOT heat up/cool down faster.
▪ When your system layout contains slow heat emitters (example: underfloor
heating), avoid large fluctuation of the desired room temperature and do NOT let
the room temperature drop too low/rise too high. It will take more time and
energy to heat up/cool down 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 heatpump convectors.
Tips about DHWtank 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
DHWtank 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 DHWtank 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 DHWtank 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.

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.
