Important information
This guide is designed to describe the operation, installation and maintenance of
the heat pump as comprehensively as possible. The description has been written
as far as possible so that it can be followed step by step.
Please note that the guide consists of three separate parts, therefore it is especially important that the installation contractor reads the entire manual before
commencing installation.
The guide is in two parts, one for the user and one for the installer. The table of
contents sets out clearly the various sections of the manual.
Warning! The Rego 600 control unit contains an advanced settings level which
should only be accessed by the installer. The end user should never change any
settings on this level, since this might cause problems with the operation of the
heat pump.
• Before the heat pump is commissioned, the heating system and the heat pump
must be filled and vented.
• Hot and cold connections might need checking after delivery.
• If the heat pump has to be carried down steps or stairs it can be tilted temporar-
ily with the compressor downwards, but never for long periods.
• The heat transfer fluid system must be in operation when venting the system.
See chapter on refilling the heat transfer circuit.
• Three phase heat pumps incorporate an alarm if the phasesare incorrectly wired.

This is how your heat pump works
Heat pump technology
The compressor, which is driven by an electric motor, forces the heat transfer fluid into the heat
pump condenser as a gas at about 100°C. The gas and the water from the radiator system pass
through the condenser, which is a fully-welded stainless steel heat exchanger. When the hot gas is
cooled by the circulating water, it condenses (changes to liquid). As it does so, it provides energy for
the heating system or the hot water. After the condenser, the refrigerant, which is now in liquid form,
continues through a drying filter and a tank. The filtercollects any moisture in the system and the tank
is used as an expansion vessel for the heat transfer fluid to ensure there is always the correct amount
in the condenser.
After the filter, the heat transfer fluid passes through a sight glass. The sight glass is used to check the
amount of heat transfer fluid in the system. In normal operation there should be no bubbles in the
sight glass. However, bubbles may appear for short periods, mainly on rapid changes between hot
water and radiator operation and when the heat pump starts or stops.
After the sight glass the heat transfer fluid goes to an expansion valve. The valve acts as a flow
restrictor between the high and low pressure sides of the system. The valve, which has a sensor
(bulb) just before the compressor, releases the right amount of liquid into the next heat exchanger, the
evaporator. In the evaporator, the liquid meets the circulating heat transfer fluid coming from the
energy source in the ground or bore hole. In this process, the liquid turns to gas (evaporates) under
low pressure, which uses heat. The heat is extracted from the outside air free of charge.
After passing through the evaporator, the heat transfer fluid is once more in the form of a gas (vapour). The expansion valve sensor constantly checks that the evaporator is performing optimally, in
order to use as much free energy as possible. The gaseous refrigerant then goes to the suction side of
the compressor, where it is compressed again. This completes the heat transfer fluid circuit.
Pressure switches are fitted on the high and low-pressure sides of the system to protect the heat
pump. These shut down the heat pump if the pressure in the system reaches an abnormal value. This
is dealt with in more detail in the section on troubleshooting.

Principle
Principle of heating and hot water control
Your heat pump is fitted with a Rego 600 control unit to guarantee you maximum savings and many
years of service. The unit, which has advanced monitoring functions, controls the heating and hot
water in your home. This ensures that all vital functions are monitored and that, if problems arise, the
heat pump is shut down before it is damaged.
When the heat pump is not able to meet the heating requirements, supplementary heat is connected
that together with the heat pump provides the required temperature. The Greenline E series has a
built-in electric heater that can be connected in three steps. The supplementary heat only provides
the output that the heat pump cannot generate and in this way can never take over heating the house
completely. When the heat pump is once more able to meet the heating demand, the supplementary
heat is automatically switched off. An oil-fired boiler is normally used to provide supplementary heat
for the Greenline D series. In which case Rego 600 controls the oil-fired boiler and the existing mixer
valve.
The heat pump is connected to the return line of the heating system so that it always receives the
coldest water. The water is heated in the heat pump and is then fed back to the heating system.
While the heat pump is heating the domestic hot water by using the electric water heater, the heating
system is disconnected temporarily through the three-way valve. A sensor in the hot water cylinder
makes sure that priority is always given to heating the hot water. When the water in the cylinder
reaches the required temperature, heat is once more supplied to the heating system.
Power failures
If the power supply fails, the control unit remembers all its settings and re-starts the heat pump when
the power returns.
Three different operating modes
The control unit can be used for three different operating modes: A, B and C. The three operating
modes are described schematically in the Installer chapter.
Operating mode A (D and E series)
This is the factory setting, based on an outdoor sensor and controls the heating temperature through
an adjustable control curve. Water heating takes priority over space heating. As well as operating
the heat pump, Rego 600 can also regulate other heat curves with a mixing valve, e.g. through a
combination of radiator and floor heating systems. An electric water heater is used for additional
heat.
Operating mode B (D series only)
Used when additional heat is from an oil-fired boiler. Operation is the same as for operating mode A.
Rego 600 cannot control other heat curves in this operating mode.
Operating mode C (D series only)
Used in exceptional cases, it does not provide optimal operation for the heat pump because it always
works with a high temperature, or “Fixed Temperature”. This is often used in operation with one or
more accumulator tanks. The tank is always kept at a high temperature and the hot water is often
heated in one or more coils.
11
Controls
The control unit operates the heat pump in three ways. We call them Curve Control, Room Sensor
and Fixed Temperature. Below follows a brief description.
Curve control (operating modes A and B)
This is the most common mode and is also the factory setting. With curve control, the heat pump
adapts the heating inside the house on the basis of the outside temperature. An outside sensor sends
signals to the control unit, which automatically adjusts the supply of heat to the heating system. This
maximises savings, since the heat pump never needs to work at a higher temperature than necessary.
The heat pump only delivers the maximum temperature when heating the hot water. Normally, hot
water heating accounts for 20% of the total annual energy requirement.
Room sensor (operational modes A and B)
A room sensor can be connected to the heat pump. It sends signals to the control unit and in this way
affects the curve control. The sensor influences the curve control and the amount of influence can be
set on the control panel. Normally, room sensors are only used when a fan-assisted radiator is used
in a house with direct electric heating or when a wood-burning stove is used in the house or where
the house is effected by wind chill or solar gain.
Fixed temperature (operating mode C only)
This control technique is rarely used, and does not offer optimum savings from the heat pump. The
principle is that the heat pump is switched on and off by the built-in return sensor and always works
up to its maximum working temperature. The normal area of use for this is together with existing
accumulator tanks.

Control panel
Control panel buttons and displays
The control panel is the heart of your heat pump installation. From the control panel, instructions are
sent to the Rego 600 control unit, which ensures that the house is uniformly heated. All settings are
carried out here and the display shows the settings that have been set.

gives more effect from the room sensor. Please note the
room sensor only fine tunes the heat curve. It is therefore important that you set the basic settings for the
heat curve and fine tuning from the start.
If a room sensor is installed you can utilise the holiday mode
function, you can set the number of days that the room
temperature is lowered to 15°C here. The temperature is
not adjustable and it does not affect the hot water. Normal
operation is resumed when the period is over.
If a room sensor and remote control is installed you can set
the required room temperature here. You can then use the
telephone to increase the temperature to normal.
This equipment is available as an accessory.

In line 7 you can read the running times for the heat pump
and additional heat. Press “Select” to enter these menus.
Here you can see how many hours the heat pump has been
in operation.
This shows the distribution of the heat pump between hot
water and heating as percentages.
Here you can see how many hours the additional heat has
been in operation.
This shows the distribution of the additional heat between
hot water and heating as percentages.
You can set the heat pump’s clock to the correct time if it is
wrong on line 10.
Line 11 shows a record of the alarms that may have occurred on your heat pump. You can see the type of alarm
and when it occurred. An * in the display means the alarm is
still active.
If you want to change your settings at customer levels 1 and
2 you can return to factory settings on line 12.
Please note: If you are on the installer/service level when
you choose factory settings, the installer must carry out a
new start-up of the plant with the new settings. The installer/
service level is for installer only. As an end-user you should
never go into this level!

Cold weather:
If the indoor temperature is too low or too high during cold
weather, you use Temp. incr./decr. to change it.
Press “Heat”.
The set value is shown on the display; in the shape of a bar
but also as a digit. The range is between 0 and 10. Press
“Adjust”.
Turn the dial to the right to increase, to the left to decrease.
The example shows how you increase the value to 5. Turn
the dial until 5 appears on the display. The new value now
appears on the display. Press “Save” to save the new
value.

Setting the heating
In the Temperature “increase/decrease” display
you use the dial to change the heat curve. The
lines show how the return temperature varies
with the outside temperature for different settings. The colder the weather the warmer the
heating system. Curve 4 is the factory setting
and in the example you can see that this gives a
return temperature of around 35°C at an outdoor temperature of 0°C.
Please note that the flow temperature is then around 7-10°C warmer. During the first winter, the
heating curve must be set up so that the temperature in the house is pleasant whatever the weather. You
should adjust the heating curve when the outdoor temperature is around 0ºC. You should wait two days
after adjusting before carrying out any readjustments.

Warm weather (above +5ºC):
If the indoor temperature is too low or too high during
warm weather, you use fine tuning to change it. You come
to Temp. Fine Tuning by pressing “Heat” and turning the
dial to the right.
Fine tuning can be set in areas –10°C to 10°C. You change
the fine tuning in the same way as “Temp. increase/decrease” as described on the previous page.
The heat curve can also be fine tuned. You do this in the “Temp. fine tune” display. The dotted line
illustrates how the parallel offset has been turned towards plus. The entire curve moves upwards, in
contrast to increasing the slope, when only the slope changes.
The dotted line illustrates
how the fine tuning adjustment has been turned
towards plus.

Fixed temperature (D series only)
If the heat pump is set at operating mode C with a fixed temperature, then it can only be engaged
and disengaged by the built-in return sensor. There are two displays available for this mode. Please
note that if a mixing valve is connected to the heat pump, the “Temp. incr/decre” and “Temp. fine
tune” displays control the settings for the mixing valve opening to the heating system.

To adjust the engaging and disengaging temperature, press
“Menu” followed by “Select”. You are now in line 1.
Use the dial to navigate to display 1.16 and press “Select”.
The factory setting is 48°. Please note that this concerns the
engaging temperature to the heat pump. The temperature
from the pump is normally 5-10°C higher. Settings above
48°C are not recommended for technical reasons.
You can also set the difference between engaging and
disengaging the heat pump in display 1.17. The factory
setting is 5ºC. A lower setting results in the heat pump
starting and stopping more frequently. Press “Select” to
adjust.
Simple tips for saving
The lower you can keep the temperature of the heating system in the house, the better your heating
economy will be. So make sure not to set your heat curve too high. It is important that the heating
system is carefully balanced so that all parts or the heat emitters (radiators or underfloor) are at the
same temperature.
Thermostatic valves on your radiators or floor heating may have a negative effect on your heating
system because they restrict the flow so that the system has to compensate with a higher water
temperature. If thermostat valves are fitted, they should be fully opened, except in bedrooms, where
they can be turned down slightly.
