3.6 Heat pump for heating and cooling

ATTENTION!
The thermal energy meter measures the quantity of thermal energy
supplied by the heat pump. The cooling capacity is not measured.
ATTENTION!
In the case of reversible heat pumps with additional heat exchanger, two
thermal energy meters must be installed. The first one is for the heating
circuit, and the other is for the circuit via the additional heat exchanger.
This second thermal energy meter measures the quantity of thermal
energy required for domestic hot water and/or swimming pool water
preparation.
ATTENTION!
With reversible heat pumps, the connection for the external heating/
cooling switch over is no longer made via digital input N1/J7-ID12. From
software version H61 onwards, the heating/cooling switch connection is
made via input N2/J5-ID4!
With reversible heat pumps with additional heat exchanger, the
hydraulic domestic hot water and swimming pool circuit is sepa-
rated from the heating circuit. A second, additional thermal en-
ergy meter must therefore be installed for the measurement of
the domestic hot water and/or swimming pool preparation.
The signal line and the voltage supply of the first thermal energy
meter are connected to the following terminals of the heat pump
controller (N1) as described in see Chap. 3.5 on p. 7 (depending
on the heat pump manager):

The second thermal energy meter requires its own voltage sup-
ply, which can either be provided directly via the mains power
supply or via the terminal strip (mains L/N/PE, 230 V AC) of the
heat pump manager.
Depending on the heat pump manager, the signal line of the sec-
ond thermal energy meter is connected to the following termi-
nals:
