2.2.6 Connection with the heat pump
The HPM controller is capable of controlling the Panasonic heat pump via a contact
(demand) signal. Communication via contact signal only offers the possibility to send
a demand for the heating circuits through the signal.
Direct communication with the heat pump via a communications port provides the
controller with the advantage of being able to send the current flow temperature
setpoints for heating or cooling, as well as for domestic hot water. Cascade control of
up to 3 heat pumps via HPM controllers is also possible. An additional HPM(2)
controller is needed for control of the second and third heat pump in a cascade.
Activation via contact

The HPM controller can send a heat demand to the heat pump via an activation
(release) signal. A heat demand will cause the contact to close. The heat pump then
provides a flow temperature generated from its own internal heating curve (which is
stored in the operating unit of the heat pump). The HPM controller cannot make any
adjustments to this flow temperature via the contact signal. In systems with domestic
hot water control, the loading process of the domestic hot water tank is not controlled
by the HPM controller but by the internal control strategy of the heat pump.
Depending on the desired system (heat production for domestic hot water + heating,
or heating only), the activation signal of the HPM must be connected to the following
external connections of the heat pump:
For heating and DHW: Function “Room thermostat” – Terminal 9 + 12
For heating only: Function “External control signal/remote switch” – Terminal
17+18
