5 Application guidelines
5.4.5 Combination: Standalone DHW tank + Solar
panels
By connecting the DHW tank to solar panels, the DHW tank can be
heated by solar energy.
For installation instructions, see the installation manual of the solar kit
and addendum book for optional equipment.
5.4.6 DHW pump for instant hot water
Setup
Q
By connecting a DHW pump, instant hot water can be available
at the tap.
Q
The DHW pump and the installation are field supply and the
responsibility of the installer.
Q
For more information about connecting the recirculation
connection (for integrated DHW tank), see the installation
chapter.
Configuration
Q
For more information, see the configuration chapter.
Q
You can program a schedule to control the DHW pump via the
user interface. For more information, see the user reference
guide.
5.4.7 DHW pump for disinfection
Setup
Q
The DHW pump and the installation are field supply and the
responsibility of the installer.
Q
For the integrated DHW tank, the temperature of the DHW tank
can be set to maximum 60°C. If applicable legislation requires
higher temperature for disinfection, you can connect a DHW
pump and heater element as shown above.
Q
If applicable legislation requires disinfection of the water piping
until the tapping point, you can connect a DHW pump and
heater element (if needed) as shown above.
Configuration
The indoor unit can control DHW pump operation. For more
information, see the configuration chapter.
5.5 Setting up the energy metering
Q
Via the user interface, you can read out the following energy
data:
Q
Produced heat
Q
Consumed energy
Q
You can read out the energy data:
Q
For space heating
Q
For space cooling
Q
For domestic hot water production
Q
You can read out the energy data:
Q
Per month
Q
Per year
5.5.1 Produced heat
Q
Applicable for all models.
Q
The produced heat is calculated internally based on:
Q
The leaving and entering water temperature
Q
The flow rate
Q
The power consumption of the booster heater (if applicable)
in the domestic hot water tank
Q
Setup and configuration:
Q
No additional equipment needed.
Q
Only in case a booster heater is present in the system,
measure its capacity (resistance measurement) and set the
capacity via the user interface. Example: If you measure a
booster heater resistance of 17.1
Ω , the capacity of the
heater at 230 V is 3100 W.
