Chapter 1 General information

This operating manual consists of a detailed description of the installation and
commissioning of the HPM controller. The manual describes the individual parts of
the controller as well as its operation, how to connect sensors, pumps and valves,
selecting the system diagram and how to make additional adjustments to adapt the
controller to the construction of a individual system and its installed heat pump(s).

The appendix of the manual contains the most common system diagrams along with
the complete menu structure, an overview of the available types of heat pumps (type
of communication), an overview of the possible heating curves, a description of
cascade control (i.e. using more than one heat pump with communication) and
information for configuring web communication (Ethernet/network interface).

To simplify controller operation, its display will show only such parameters and menu
items that are currently relevant. I.e., if a boiler has been selected as the heat source,
menus pertaining to the operation of district heating and heat pumps will not be
visible. Or, supposing there is no return temperature sensor assigned to a terminal, no
entry will be visible in the menu ”Current values” pertaining to a return temperature.

The selected and loaded system diagram, along with any additional manual
adjustments made, decide what will be displayed in the menu system of the controller.

1.1 HPM tool: Selecting the system diagram

To select the system diagram, Panasonic offers a web-based tool called “HPM tool”.

HPM tool is a web-based software accessible via the address

www.hpmtool.eu by

using a standard Internet browser

HPM tool permits quick and easy selection of the right system diagram for your
heating system.

Fig 1.1: Different modules are combined into a system diagram. HPM tool then provides a system diagram
number which is entered into the controller and the corresponding terminal configuration

By making selections from the menu system near the top of the screen, the modules
can be combined into a system diagram corresponding to the actual heating system in
use. HPM tool then generates a system diagram number. This has to be entered during
initial startup of the controller.

The terminal configuration displayed in HPM-tool shows to which input and output
terminals the sensors, pumps and valves must be connected. The terminal
configuration can either be printed out or saved as a Microsoft Excel file.

* Communication with a heat pump requires additional adapter cable of model INT-X

Table 1.1: Controller types

The HPM1 is a standardized controller for systems including a heat pump. Control of
the heat pump can take place either via a contact or via communication. A HPM
controller can be used for cascade control of up to 3 heat pumps. For demand via
contact, only one HPM1 is required. When utilising cascade control via a
communication port, one HPM1 is required as a master controller and up to 2 HPM2
as slave controllers (for communication with heat pumps 2 and 3). In addition, the
HPM controllers must be connected via an Ethernet port.

1.5 The socket

The socket of the HPM constitutes a separate component in which the terminals are
contained and the wires connected. The socket is divided by a separator into 2 parts.
The left-hand side contains low voltage connections, such as for sensors and 0...10 V
terminals, and the right-hand side contains high voltage connections (230 V) for
actuators and pumps.

Fig. 1.7: The socket

Each section of the socket contains ground multipliers, which are situated
immediately next to the terminals. Low voltage and high voltage use separate grounds
to prevent electromagnetic influence.

To fasten the socket to the controller, simply slide the controller onto the socket and
push the two clips on each side of the socket. A screwdriver is required in order to
open the clips again.

Fig. 1.8: Cable knockouts and clip to fasten the socket

The cable inlets must be pressed out where needed. The holes are prepared for
standard M-cable glands.

1.6 The interfaces

Depending on the type of controller, a number of interfaces are available:

Fig. 1.9: The interfaces

USB

Each controller is equipped with an USB interface. The USB interface can be used to:

x Make adjustments.

x Create a backup of the configuration.

x Upload backups or new firmware.

The only equipment neccessary is a normal USB-to-Micro-USB interface cable and
the necessary COM-port driver as required by the computer’s operating system.

External display (RS-485)

This interface enables connecting a remote control unit (e.g. an external touch panel).

Communication with the heat pump (RS-485)

This interface is used to communicate with the heat pump. To connect the heat pump,
a PAW-HPMINT-X model adapter cable is needed. The “X” stands here for either “–
U” (a 3 m adapter cable to communicate with the internal unit of a split-heat pump) or
“–M” (a 30 m adapter cable to communicate with a MONO-block-heat pump). In this
case, the HPM functions as a substitute for the operating unit of the heat pump.

Network (Ethernet)

If the controller is equipped with an Ethernet interface, it can be connected to a
communications network which can in turn be connected to the Internet. The interface
can be used to:

a) Communicate with the controller.

b) Connect master and slave controllers when using more than one heat pump in the

system.
