This guide provides the heat pump installer with a description of how the heat
pump and the hot water heater, if used, are installed and commissioned. The
installation section consists of a plumbing part and an electrical par t. It also
provides technical data such as measurements, wiring diagrams and installer
menus. We hope that you read through this guide carefully and that you
respect all notes and warning texts.
Note
It is important that as the installer you also read through the User guide for the
heat pump. Here you will fi nd the information necessary to get a comprehensive
understanding of the heating installation.

This manual gives you all the information necessary to install the heat
pump. The guide is divided into several parts in the order in which installation and commissioning must be carried out.
Before starting the installation:
The heat pump may be temporarily tilted with the compressor
downwards. It must never be laid down or transported horizontally.
Check that plumbing connections in the heat pump are intact and have
not shaken loose during transport.
If the heat pump is used in a system with fan-assisted radiators, the
water volume in the system is very small. During defrosting, the heat
pump draws some of the energy from the heating system, cooling
it down. It is therefore important that the fans in the fan-assisted
radiators run during defrosting, alternatively are connected to a tank of
approximately 100 litres.
Wiring should be kept as short as possible to protect the system from
downtime, for example during a thunderstorm.
Before the commissioning the heating system must be filled up and
completely vented.
Important information for the installer
Checklist
The following checklist will give you a general description of how the installation
should be carried out.
1. Position the heat pump on a solid base.
2. Install the incoming and outgoing pipes for the heat pump.
3. Install the drainage pipe for the heat pump.
4. Install the new hot water heater, hot water sensor and three-way valve if used.
5. Install G2 heat carrier pump.
6. Install a mixing valve if not already installed.
7. Fit the particle filter.
8. Connect the heat pump to the heating system.
9. Install the control cabinet and the accessory unit for electric/oil-fired boiler.
10. Install the flow sensor, outdoor sensor, and room sensor if used.
11. Connect the CANbus wiring between the heat pump and the control cabinet.
12. Connect the heating installation to the power supply via a safety switch and
any earth fault breaker.
13. Fill and vent the heating system before commissioning.
14. Commission the heating installation by making all the necessary settings on
the control panel.
15. Check the heating installation after commissioning.
Warning
For reasons of safety the main power
supply must be disconnected before
working on the heat pump.

Positioning the heat pump
The heat pump is located outdoors. It contains a number of sensitive
parts. It is impor tant that it stands on a flat and solid base, for example,
concrete slabs on ground insulation.
The installer should take sound propagation into consideration when
positioning the heat pump. See more information under the heading
Technical information/Sound levels.
Pipe routing between the heat pump and the existing heating system
should be as short as possible. The outdoor pipes must be insulated.
The heat pump produces condensation and melted ice during the
defrosting process. It is therefore important to lead off this water from
the heat pump to a floor drain inside the house.
Note that the drainage pipe must slope towards and run out above the
floor drain. This will keep the drainage pipe free of frost as air is drawn
from inside the house. In those cases the drainage pipe is released into
the surface water outdoors, the pipe must be fitted with a heating cable
(accessory) to avoid freezing. A suitable output is 10-20 W/metre. The
cable can be connected to terminals in the heat pump. See External
connections.
The heat pump must be positioned so that air is not prevented from
passing through the evaporator. Minimum distance to a wall is
300 mm. Avoid positions which result in circulation of cold air because
this decreases the heat pump output.
Avoid falling snow and eaves drop. In some cases a protective roof may
be necessary. The roof should then be installed at least 1.5 m above the
heat pump to avoid the recirculation of cold air.
General
Transporting and storage
The heat pump should always be transported and stored in an upright
position. Otherwise the suspension fi ttings inside the compressor can be
damaged. If the heat pump must be tilted during entry to the installation
site, this should be done for as short a time as possible.
The heat pump must not be stored at temperatures below 0ºC.
Note
The amount of condensation water
can, during days of high humidity,
amount to 30-40 litres.
General
9
Maximum working temperatures
The heat pump can work with a maximum return temperature of approximately 59ºC. If the temperature rises above this value the heat pump will
stop for reasons of technical safety.
The maximum fl ow temperature from the heat pump or additional heater is
limited to 65ºC.
Minimum working temperatures
The heat pump stops if the outdoor temperature falls below approx -20ºC.
All heat production then occurs in the existing electric/oil-fi red boiler.
The heat pump starts automatically when the outdoor temperature climbs
above approx -20ºC.
The heating installation’s different methods
of control
The control unit uses different methods to control the heating installation.
These are: Control with an outdoor sensor and Control with an outdoor
sensor supplemented with a room sensor.
More information about the control methods can be found in the User
Guide for Optima.
General
Minimum and maximum working temperatures
Defrosting method
The principle of defrosting in the heat pump is known as hot gas defrosting. During defrosting, the fl ow in the refrigerant circuit is reversed by
means of an electrically-controlled four-way valve. The compressed gas
from the compressor is fed into the top of the evaporator, causing the ice
on the outside to melt. During this process, the heating water is cooled
slightly. Hot gas is sprayed into the evaporator and sensor T11 ensures that
the process functions correctly. The time required for defrosting depends
on the amount of ice and the outdoor temperature.
There is also a fan defrost function, which means that hot air blows
upwards through the fan to prevent it freezing solid.

General
In Rego 800 the different circuit boards are connected by a communications cable, CANbus. CAN is an abbreviation of Controller Area Network
and is a two wire system for communication between the microprocessor
based modules/circuit boards. These are connected in series.
The heat pump has one circuit board (IOB circuit board). The accessor y
unit electric/oil-fi red boiler has one circuit board (IOB circuit board).
Other circuit boards (CPU, PSU and IOB circuit boards) are in the control
cabinet.
Suitable cable for external laying (connection between the circuit
boards) is cable ELAQBY 2x2x0.6. The cable must be twisted pair and
screened. The screen must only be earthed at one end and to the chassis
(not to a circuit board). Maximum cable length is 20 m.
The CANbus cable must not be laid alongside power supply cables. It may
be laid alongside sensor cables.
In the connection area of the heat pump the external CANbus cable must
be laid so that it does not come into contact with high current connections
(230/400V).
The connection between the circuit boards is by four wires since the
12V-supply between the circuit boards must also be connected. The circuit
boards have markings for both the 12V and CANbus connections.
Warning
Do not mix up the 12V and CANbus connections! If 12V (or other
incorrect voltage) is supplied to the
CANbus contacts the processors in the
CANbus are destroyed. Check, therefore, that the four cables are connected
to the contacts with the corresponding
marking on the circuit boards in the
accessory unit and the heat pump.
Switch S1
The switch is used to mark the start and end of a CANbus loop. This
means that the IOB circuit board in the heat pump and the accessory unit
circuit board must be terminated using S1, which must be in position Ter m.
Ensure that this is the case and that all other switches are in the opposite
position.
CANbus
Warning
The CANbus cable must be screened
and laid separately from the power
cable to prevent interference in the
CANbus communication.
Screen
Warning
Handle the circuit boards with great
care. They are sensitive to ESD (Electrostatic discharge), which can cause
faults in electronic components.
