Energy saving tips

Tips about room temperature

▪ Make sure the desired room temperature is NEVER too high, but

ALWAYS according to your actual needs. Each saved degree can
save up to 6% of heating 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  needs.  If

necessary, you can easily deviate from the schedule:

▪ For  shorter  periods:  You  can  overrule  the  scheduled  room

temperature. 

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. 

Example:

When  you  stay  at  home  during  your  holiday,  or  when  you  go
away during your holiday.

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.

Maintenance and service

5.1

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 indicated on the manometer

is above 1 bar.

Refrigerant

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

Refrigerant type: R410A

Global warming potential (GWP) value: 2087.5

NOTICE

In  Europe,  the 

greenhouse  gas  emissions

  of  the  total

refrigerant  charge  in  the  system  (expressed  as  tonnes
CO

2

-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.
