The following table summarizes the required configuration and
thermostat wiring at the terminal block in the switch box. Pump
operation is listed in the third column. The three last columns indicate
whether the following functionality is available on the user interface
(UI) or handled by the thermostat (T):
• space heating or cooling on/off ( o )
• heating/cooling changeover (

• heating and cooling schedule timers ( pr )
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 unit is designed to receive an input signal by which the unit
switches into forced off mode. At that moment, the unit compressor
will not operate.

Warnings
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" on page 20 .
If heaters must be controlled at moments that the
benefit kWh rate power supply is off, then these
heaters have to 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
Benefit kWh rate power supplies that completely shut
power supply are not allowed for OP10 models because of
the heater tape that would not be powered.
