Use case 2
Energy buffering happens in the domestic hot water tank only.
Energy buffering System requirements Description
Domestic hot water tank ▪ Make sure a domestic
hot water tank is part of
the system.
▪ On the user interface,
make sure to set:
- [E-05]=1
- [E-06]=1
The system produces
domestic hot water. The
tank heats up the water
up to the maximum tank
temperature (depending
on the tank type).
INFORMATION
▪ The system will ONLY buffer energy when the indoor unit is NOT in normal
operation. Normal operation has priority over energy buffering.
▪ Normal operation CAN be either: Domestic hot water operation (setpoint is
not reached during a scheduled operation or a reheat operation), or safety
functions (e.g. Antifrost or Disinfection).
▪ The maximum temperature during domestic hot water tank buffering is the
maximum tank temperature for the applicable tank type.
INFORMATION
Energy buffering in the domestic hot water tank will ONLY happen when the excess
PV power, which is the difference between the generated solar power and the
househould power consumption, exceeds the fixed threshold of 1.45kW. This value
ensures there is enough grid injection to operate the immersed heater and includes a
safety margin to allow for 10% grid variation.
INFORMATION
Because of cloudy weather circumstances or sudden peaks in household
consumption, the excess PV power CAN fluctuate. To avoid frequent switching of the
unit operation, a timer is implemented so that buffering will ONLY stop when the
excess PV power drops below the threshold for at least 5 minutes. Due to this, the
unit CAN temporarily consume energy from the grid to continue buffering.
Buffering in case [C-07] = 0 OR 1
When, on the user interface, [C-07] = 0 OR 1 (the unit control method is leaving
water temperature control OR external room thermostat control), then the system
can only buffer energy in the domestic hot water tank, and only in the following
two separate cases:
▪ Space heating/cooling operation is turned OFF
OR
▪ During space heating operation:
- Outdoor temperature > space heating setting [4-02]
- Room frost protection is not active
▪ During space cooling operation:
- Outdoor temperature < space cooling setting [F-01]
