3 Press to save the schedule.
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.
4.4 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.
4.4.1 To set the gas price in case of an
incentive per kWh renewable energy
Prerequisite: Calculate the value for the gas price with following
formula: actual gas 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.
4.4.2 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.
4.4.3 Example
This is an example and the prices and/or values used in this
example are NOT accurate.
Data Pence/kWh
Gas price 4.08
Electricity price 12.49
Renewable heat incentive per
kWh
5
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
Price Value in breadcrumb
Gas: 4.08pence/kWh [7.4.6]=8.58
Electricity: 12.49pence/kWh [7.4.5]=17.49
5 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 *HY2KOMB28+32AA gas boiler):
calculated by the interface itself based on an internal calculation.
5.1 To view the energy statistics
Prerequisite: You switched the permission level to Advanced end
user.
1 Go to [6.2]: > Information > Energy metering.
2 Select Consumed elec. or Consumed gas.
3 Use the and buttons to toggle between views of the
current month, the previous month, the last 12 months and a
general overview.
4 Use the and buttons to toggle between different modes
(if applicable).
6 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.
