INFORMATION
The values for High, Medium and Low correspond with the
electricity price values for High, Medium and Low
previously set. If no schedule is set, the electricity price for
High is taken into account.

About energy prices in case of an
incentive per kWh renewable
energy
An incentive can be taken into account when setting the energy
prices. Although the running cost can increase, the total operation
cost, taking into account the reimbursement will be optimized.
NOTICE
Make sure to modify the setting of the energy prices at the
end of the incentive period.
5.4.1
To set the fuel price in case of an
incentive per kWh renewable energy
Prerequisite:
Calculate the value for the fuel price with the following
formula: actual fuel price+(incentive/kWh×0.9)
1
Go to [7.4.6]:
> User settings > Preset values > Fuel price.
2
Use
and
to set the correct price.
3
Press
to confirm.
5.4.2
To set the electricity price in case of an
incentive per kWh renewable energy
Prerequisite:
Calculate the value for the electricity price with
following formula: actual electricity price+incentive/kWh.
1
Go to [7.4.5]:
> User settings > Preset values > Elec price.
2
Use
and
to set the correct prices for High, Medium and
Low, according to your electricity tariff.
3
Press
to confirm.
INFORMATION
Solar panels.
If solar panels are used, set the electricity
price value very low to promote the use of the heat pump.

Calculation of the gas price:
Gas price=Actual gas price+(incentive/kWh×0.9)
Gas price=4.08+(5×0.9)
Gas price=8.58
Calculation of the electricity price:
Electricity price=Actual electricity price+incentive/kWh
Electricity price=12.49+5
Electricity price=17.49

Energy visualisation
The user interface is able to graphically display energy statistics for:
▪ consumed electricity: calculated by the interface itself based on an
internal calculation.
▪ consumed gas (only in case of EHY32AA gas boiler):
calculated by the interface itself based on an internal calculation.

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 leaving water temperature
▪ In heating mode, a lower desired leaving water temperature
results in lower energy consumption and better performance.
▪ 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.
