3. Small amount of excess power:

The power supply utility provides the power at a low

price.

If a time phase is active in the time program, the

heat pump is started. To make use of low-cost elec-

tricity, additional energy can be stored in your sys-

tem. For this purpose, your contractor may have

increased (or reduced, for cooling) the set tempera-

ture values for the following functions:

■DHW heating

■Buffer cylinder heating

■Central heating

■Room cooling

4. Large amount of excess power:

The power supply utility provides the excess power

at no cost.

The power supply utility starts the heat pump imme-

diately, even if no time phase is active in the time

program. System components are heated to the

max. possible temperatures or cooled to the min.

possible temperatures.

Information about operation with low-cost and free

electricity

The electric power consumption of the heat pump is

not taken into account when calculating the seasonal

performance factor.

Example: Utilisation of excess power for DHW

heating

Low-cost excess power

The heat pump is operated with excess power from the

power supply utility to heat DHW to the increased set

DHW temperature.

In the time program you have set the time phases dur-

ing which DHW heating is enabled. The power supply

utility may start DHW heating, even outside the set

time phases.

To utilise even more low-cost excess power for DHW

heating, the standard DHW temperature can be

increased. Your contractor can set the value for this

temperature increase.

■Standard DHW temperature:

50 °C

■Increase in DHW temperature (set by your contrac-

tor):

10 K (10 Kelvin)

The DHW is heated to 60 °C. If DHW consumption

remains the same, the next DHW heating period using

power at the standard tariff is postponed until later.

Free excess power

DHW heating is started immediately, regardless of

your settings in the time program.

The DHW will be heated to the maximum possible

temperature. This temperature has been set by your

contractor.

■Standard DHW temperature:

50 °C

■Max. temperature of your DHW cylinder (set by your

contractor):

65 °C

The DHW is heated to 65 °C. If DHW consumption

remains the same, the next DHW heating period using

power at the standard tariff is postponed until later.

Note

If scald protection is enabled, the DHW is heated to a

maximum of 60 °C, even if the Smart Grid settings

specify a higher DHW temperature.

Note

If you have enabled several functions for Smart Grid,

the functions for DHW heating will have priority over

the functions for room heating.

Set temperature

Specific temperature that should be reached, e.g. set

DHW temperature for example.

Drinking water filter

A device that removes solids from the drinking water.

The drinking water filter is built into the cold water

pipework to the DHW cylinder.

Evaporator

The evaporator is a heat exchanger that transfers ther-

mal energy from the outdoor air to the heat pump.

In this process, cooling of the supplied air can cause

water to condense. This condensate can freeze on the

evaporator, which has a negative effect on heat trans-

fer.
