Connection to a benefit kWh rate power supply
Electricity companies throughout the world work hard to provide
reliable electric service at competitive prices and are often authorized
to bill clients at benefit rates. E.g. time-of-use rates, seasonal rates,
Wärmepumpentarif in Germany and Austria, ...
This equipment allows for connection to such benefit rate power
supply delivery systems.
Consult with the electricity company acting as provider at the site
where this equipment is to be installed to know whether it is
appropriate to connect the equipment in one of the benefit kWh rate
power supply delivery systems available, if any.
When the equipment is connected to such benefit kWh rate power
supply, the electricity company is allowed to:
interrupt power supply to the equipment for certain periods of
time;
demand that the equipment only consumes a limited amount of
electricity during certain periods of time.
The indoor unit is designed to receive an input signal by which the
unit switches into forced off mode. At that moment, the outdoor unit
compressor will not operate.
CAUTION
For a benefit kWh rate power supply like illustrated
below as type 1
If the benefit kWh rate power supply is of the type that
power supply is not interrupted, then control of the
heaters is still possible.
For the different possibilities of controlling heaters at
moments that benefit kWh rate is active, refer to
"[D] Benefit kWh rate power supply/Local shift value
weather dependent" on page 33.
If heaters must be controlled at moments that the
benefit kWh rate power supply is off, then these
heaters shall be connected to a separate power
supply.
During the period that the benefit kWh rate is active
and power supply is continuous, then stand-by power
consumption is possible (PCB, controller, pump, ...).
For a benefit kWh rate power supply like illustrated
below as types 2 or 3
If during benefit kWh rate power supply the power supply is
shut off, then heaters can not be controlled.
This power supply interruption should not be longer
than 2 hours, otherwise the real time clock of the
controller will be reset.
During power supply interruption, the controller
display will be blank.
