Important information

This guide was designed to describe the operation, connection and maintenance of the heat pump as comprehensively as possible. As far as possible, the description has been written so that it can be followed step by step.

Please not that the guide consists of three separate series so 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 Rego600 control unit contains an advanced settings level which should only be accessed by the installer. The end user must never change any settings on this level, since this might have serious consequences for the operation of the heat pump.

• Before the heat pump is commissioned, the heating system and the heat transfer fluid

system, as well as the heat pump itself, must have been filled and vented. The heat transfer fluid system must be filled with antifreeze (-15°C).

• Hot and cold connections might need checking after delivery.

• If the heat pump has to be carried down steps or stairs it can be leaned temporarily

with the compressor downwards, but never for longer periods.

• The heat transfer fluid system must be in operation when venting the system. See

chapter on refilling the heat transfer circuit.

• The control unit measures the phase sequence and alarms if the power is connected

wrongly (only 3-phase units).

This is how your heat pump works:

Heat pump technology

The compressor, which is driven by an electric motor, forces the refrigerant 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 condensor, the refrigerant, which is now in liquid form, continues through a drying filter and a tank. The filter collects any moisture in the system and the tank is used as an expansion vessel for the refrigerant to ensure there is always the correct amount in the condenser.

After the filter, the refrigerant passes through a sight glass. The sight glass is used to check the amount of refrigerant 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 refrigerant 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 the ground or bore hole free of charge.

After passing through the evaporator, the refrigerant 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 refrigerant circuit.

To protect the heat pump, pressure switches are fitted on the high and low-pressure sides of the system. 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 Rego600 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, additional heat is connected that together with the heat pump provides the required temperature. The Greenline C and E series has a built-in immersion heater that can be connected in three steps. Factory setting is 2/3 electrical output. The additional 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 additional heat is automatically switched off. An oil-fired boiler is normally used to provide additional heat for the Greenline D series. In which case Rego600 controls the oil-fired boiler and the existing mixing valve.

The heat pump is connected to the heating system’s return flow. The water is heated in the heat pump and is then fed back to the heating system. While the heat pump is heating the water in the immersion heater, the heating system is disconnected temporarily through the 3-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 failure

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. Please note that the C series can only utilise operating mode A. The three operating modes are also outlined under Installer.

Operating mode A (C, D and E series)

This is the factory set operating mode based on an outdoor sensor that sends signals to the heat pump control unit and controls it through an adjustable control curve. Water heating takes priority over space heating. As well as operating the heat pump, Rego600 can also regulate other heat curves with a mixing valve, e.g. through a combination of radiator and floor heating systems. An immersion 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. Rego600 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 most commonly used together with existing electric boilers. This mode of operation is based on the existing electric boiler’s heater being kept warm by the heat pump and by utilising the existing immersion heater in the boiler.

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. This means that the heat pump adjusts the heat in the house based on the outdoor temperature so that the radiator temperature increases as the outdoor temperature reduces. An outside sensor sends signals to the control unit, which automatically adjusts the supply of heat to the radiators. To set the temperature of a radiator for a certain outdoor temperature, you can choose between a number of different curves on the control unit. 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 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 amount of affect the room sensor has on the curve control can be set on the control panel. The room sensor is normally only used in combination with an outdoor sensor; when a fan-assisted radiator is used in houses with electric radiators or a fire place, or in houses that are wind sensitive.

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 most common use for this control technique is when there is a relatively new electric boiler and the heat pump is connected to it. The heat pump heats the hot water cylinder in the boiler, and any additional heat required is provided by the boiler’ immersion heater. There are unfortunately not many electric boilers on the market that are suitable for use in conjunction with a heat pump.

Setting the heating

In the Temperature increase/decrease display you use the knob to change the heat curve. The lines show how the return temperature varies with the outdoor 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

o

C at an outdoor temperature of 0oC.

The example describes how to change the heat curve in the Heating increase/decrease menu. Please note that a high value could cause the heat pump to stop if the return temperature is too high.

C. You should wait two days after adjusting

before carrying out any readjustments. Also note that a lower curve setting gives a lower runnig cost.

Warm weather:

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-tune” by pressing “Heat” and turning the knob 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.

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 knob to navigate to display 1.16 and press “Select”.

The factory setting is 48°C. Please note that this concerns the return temperature to the heat pump. The temperature from the pump is normally 5-10C higher. Settings above 48°C are not allowed for technical reasons.

You can also set the difference between starting and stopping the heat pump in display 1.17. The factory setting is 5°C. A lower setting gives more frequent starts and stops for the heat pump. Press “Select” to adjust.

Simple tips for saving

The lower you can keep the temperature of the radiators in the house, the better your heating economy will be. So take make sure not to set your heat curve too high. Operate your heating system as efficiently as possible by making sure that the entire surface of your radiators or your underfloor heating coils are kept hot.

Thermostatic valves on your radiators or underfloor 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.

If something is wrong

The control unit provides a lot of information about faults and how to remedy them. The control unit incorporates advanced functions to monitor and protect your heat pump. This means there is no risk involved in resetting an alarm. If a fault persists, you should contact the installer.

Alarm examples and what to do

If the control panel is dark

Possible faults:

• The fuses or MCBs (miniature circuit-breakers) in your fuse box.

This is what to do: Check the fuse (or MCB) for your heat pump. If the small plate at the bottom of the fuse has come off, the fuse has blown and must be replaced. If you have MCBs, and they have tripped, move the switch to the up position.

Note that the heat pump cannot restart until after 15 minutes. This delay is needed for technical reasons!

• If the heat pump MCB has tripped, this is what to do:

Press ”Ackn” and the fault is remedied, the alarm lamp goes off and the heat pump starts again within 15 minutes. If the lamp is lit with a steady glow then the alarm is remedied but the fault remains. If several alarms have triggered, use the knob to navigate to them.

If you press ”Info” and then turn the knob you will see information about the possible causes and how you can remedy the fault yourself.

Maintaining your heat pump

Your heat pump normally requires little maintenance, but we recommend occasional checking to ensure that your heating installation give the best possible performance. The description sometimes refers to a heat pump component. You find these on the following pages.

Working on the heat pump

• Switch off the electrical supply before commencing work on the heat pump. Usually there is an

isolating switch on the wall before the heat pump.

• Only an accredited refrigeration company is permitted to work on the refrigerant circuit. The installa-

tion contains gases that may form toxic fumes when combined with discharges and naked flames. The gas that forms may cause choking even at low concentrations. If it should leak, evacuate the room until it has been thoroughly aired.

Normal maintenance

Points to check a few times a year:

• Sight glass (pos 6). When the heat pump starts, and during rapid temperature changes, you can

sometimes see bubbles in the liquid in the refrigerant circuit for a minute or so. This is normal. If there are always bubbles in the sight glass: Contact the installer.

Sight glass

• Expansion vessel. A plastic expansion vessel is connected to the heat pump heat transfer fluid

circuit. The level of the vessel must not fall below1/3 (the vessel is mounted outside the heat pump). Too low fluid level: With the pump working, remove the lid to the valve at the top of the vessel and open the valve. Fill with antifreeze or clean water (simplest with a watering can). Shut the valve again and screw on the lid.

Ball valve with lid

• Particle filter (pos 1, only built-in in the E series on the hot side). The particle filter, which is con-

nected on both the hot and cold sides of the heat pump protect the heat exchangers from dirt. Some-

times these filters may get clogged and cause malfunctions.

Do this when checking: Shut down the heat pump with the on/off button on the control panel. Close the valve and unscrew the sealing cover. Check for dirt in the filter. If necessary, remove the circlip that retains the filter. The simplest way to do this is by using pliers. Remove the filter and flush it clean with water. Refit the filter, circlip and cover. Open the valve and start the heat pump. Note that the particle filter in the E series is mounted inside the heat pump. On the cold side and in the C and D series the filters are outside the heat pump.

The various parts in the C series

Please note: The picture shows a 1-phase unit.

Control safety anode

(Only for models with stainless hot water cylinder) At the top of the hot water cylinder, under the insulation, there is an electronic protection anod (standard feature) Its purpose is to prevent corrosion. The cylinder must be full of water for the anode to work.

If the heat pump is equipped with a magnesium anode, the anode can corrode depending on the water quality. If its diameter has been reduced to a minimum it must be replaced. This is how you check the magnesium anode:

1. Shut off the main cold water feed.

2. Turn on a tap to reduce the pressure in the water cylinder.

3. Unscrew the anode and check it.

If the anode is electronic there is a control panel with LEDs where you can see the status of the anode. It shows a red or a green light. If the LED shows green, the anode is operating and working normally. If large amounts of hot water are drawn off (when filling a bath for instance) the LED may show a red light for a short time even though there is no fault. If the LED shows red for more than 10 hours, the anode is faulty and a service engineer must be called.

General

Temperatures

Note that the heat pump can work to a maximum return temperature of around 48°C. Anything over this and the heat pump stops for safety reasons. The maximum outgoing temperature from the heat pump is around 55°C. A higher temperature can be achieved using an immersion heater.

Particle filter

The particle filter supplied must always be fitted in the input pipe of the hot side as close as possible to the heat pump, and horizontally. The filter is mounted on the heat transfer side in the E series. The filters is separately packed on the heat transfer fluid side.

Transportation

The heat pump must always be transported and stored upright and dry. The heat pump can be placed on its back temporarily for moving into place of installation.

Positioning

Place the heat pump on a flat base and adjust the rubber feet until it is level. Avoid installing the heat pump close to sensitive walls such as bedroom walls, since the pump produces a certain amount of noise when running. The room must have a floor drain. Installation must comply with local construction regulations.

Collector

Collector hose

The collector hose consists of a thin-walled plastic hose of make Pem 40 x 2.4 DN 6.3. Length and depth as in IVT:s dimensioning program.

Install the hose rising towards the heat pump to avoid air pockets.

It is vitally important that the filling around the ground coil does not contain stones or other objects that could damage the coil. The final filling is best carried out after the ground collector has been pressure tested. Avoid chips or dirt getting into the coil when cutting.

Installation and filling around the collector hose must comply with local regulations.

Bending diameter

Minimum bending diameter permitted is 1 metre. Always use an elbow coupling for sharper bends. If you damage the hose by bending it too sharply you can repair it with a pipe joint.

Maximal lengths

Specified pressure drop and hose lengths are based on heat transfer fluid containing 29 volume percent ethanol. Other heat transfer fluids are not recommended because they give high pressure drop at low temperatures. The table shows the maximum hose length for each heat pump model. The coils can be parallel connected if the collector’s length exceeds that permitted for a circuit. Note that maximum hose length per coil is specified for parallel connecting. The table specifies that e.g. a Greenline 11 has a maximum coil length of 400 metres and for 2 parallel coils the length is 800 metres a coil, a total of 1,600 metres.

Connecting the collector to the heat pump

The sketch shows the connection of a collector with two parallel coils. Both coils are connected to two distributors. Each coil should have a gate valve and a control valve. The control valve is adjusted so that the flow is the same in both coils.

The joint pipe to the heat pump is fitted with a filling unit, a particle filter and an expansion vessel. A safety valve is fitted to the outgoing duct. When refilling with the heat transfer fluid circuit, a coil at a time is filled by shutting both valves completely.

Switching to side mounting of the heat transfer fluid system

When delivered Greenline Compact is designed for top mounting on the heat transfer fluid (collector) side. This can be changed to side mounting on the right or left side. The following instructions describe the process step by step. We recommend that rebuilding is completed before placing the heat pump in its place of installation.

The right side plate has two connection points. Swap right and left side plates if you want to connect on the left side. Remove the plastic plugs from the sideplate (1) and put them in the holes on the roof cover panel (2).

Remove both the heat transfer fluid pipes that go to the top of the top plate. Heat transfer fluid in is equipped with a connector on top of the heat transfer fluid pump. Heat transfer fluid out is connected to the bottom of the heatexchanger. Note that the sensor on heat transfer fluid out must first be removed.

The armaflex insulation is removed from both pipes when removing the heat transfer fluid pipe from the heat pump.

Both heat transfer fluid pipes are cut to suit left or right mounting. The following series of pictures provide the exact measurements. The pipes are cut the same whether they are left or right mounting.

- Heat transfer fluid out can be cut as shown in figure B then a bend and a straight piece of copper pipe can be soldered in.

The piece of pipe can be taken from the piece that was over when the pipe was cut.

Do not use compression fittings because of the lack of space in the heat pump.

LEFT MOUNTING:

- Heat transfer fluid out is cut as shown in figure C then a bend and a straight piece of pipe are soldered in.

- Heat transfer fluid in is cut as shown in figure D then a joint and a straight piece of pipe are soldered in.

You can use material that was over when the pipe was cut.

Do not use compression fittings because of the lack of space in the heat pump.

- When the pipes have been adjusted they are mounted inplace again.

- The sensor is mounted back on the heat transfer fluid out with a piece of aluminium tape.

- The armaflex insulation is pushed back onto both pipes. Use a piece of armaflex tape tocover the pipe properly to avoid condensation.

Ground water system

Application:

Systems using ground water are equipped with an intermediate heat exchanger to eliminate the risk for freezing. A pump with a non-return valve is placed in the bore hole that via a hose pumps the water to the intermediate exchanger and then back to an injection well. The circuit to the heat pump is installed in the normal way with a filling unit and safety valve. The circuit should contain around 29 volume percent antifreeze (ethanol or ethylene glycol) which corresponds to around -15

o

C freezing point.

Electrical connections:

The ground water pump is connected to 3 x 400 volt with a motor cutout and a contactor. Power to contactor CK3(230V) is fetched from terminals L and N (P3) in the heat pump. The auxiliary contact for motor cutout MB3 is series connected with the MB2 alarm. In this way the ground water pump starts and stops with the heat pump’s heat transfer fluid pump and during motor cutout MB3, the heat pump stops and the heat transfer fluid pump alarm shows in the alarm display. NOTE: Single-phase pumps should always be connected with a contactor. It should never be connected to the P3 outlet in the heat pump.

Application:

The principle for operating mode A is based on liquid condensation and additional heat from an electric water heater. The built-in control unit Rego600 controls the heat pump with an outdoor sensor GT2 and return sensor GT1 according to outdoor compensated control curve. When the heat pump is not able to meet the heating requirements, additional heat starts that together with the heat pump provides the required temperature. Hot water is prioritised and controlled by a sensor, GT3 in the hot water heater. While the heat pump is heating the water in the immersion heater, the heating system is disconnected temporarily through the three-way valve. Radiotor operation continues when the immersion heater is hot enough. Rego600 can also control other curves together with a mixing valve. The mixer curve must be set lower than the curve for the rest of the heating system. This extra function is used e.g. for floor heating systems that demand a lower temperature.

Connecting the sensors:

External sensors GT1 and GT2 must always be connected. Sensor GT4 is connected if the mixer curve is used and GT5 if the room sensor is required.

*Acc. tank:

A 100-300-litre accumulator tank is recommended for systems with separate controls for e.g. floor heating, to ensure good operational times for the heat pump. For this solution, GT1 is mounted in accordance with *GT1.

External sensors GT1 and GT2 must always be connected. GT3 is connected if the heat pump is to produce hot water. Sensor GT4 is connected if the mixer curve is used and GT5 if the room sensor is required.

*Acc. tank:

A 100-300-litre accumulator tank is recommended for systems with separate controls for e.g. floor heating to ensure good operational times for the heat pump. For this solution, GT1 is mounted in accordance with *GT1.

(X) The distance between both cut offs must not be more than 10 times the dimension of the pipe.

It is also possible to control other heating systems with a mixing valve. For example, for a combination of radiator and floor heating systems.

MIXED HEATING SYSTEM

Application:

The principle for operating mode B is based on liquid condensation and additional heat from an oil-fired boiler using a mixing valve. The built-in control unit Rego600 controls the heat pump with an outdoor sensor GT2 and return sensor GT1 according to outdoor compensated control curve. When the heat pump is not able to meet the heating requirements, the oil-fired boiler starts automatically and together with the heat pump provides the required temperature. Hot water is prioritised and controlled by a sensor, GT3 in the hot water heater. While the heat pump is heating the water in the immersion heater, the heating system is disconnected temporarily through the 3-way valve. If the oli-fired boiler is in operation it provides the required temperature to the radiator system. Radiotor operation continues when the immersion heater is hot enough.

Connecting the sensors:

External sensors GT1 and GT2 must always be connected. GT3 is connected if the heat pump is to produce hot water. GT5 if use of a room sensor is required.

Application:

The principle for operating mode C is based on a fixed temperature and additional heat from an immersion heater. Rego600 controls the heat pump with a built-in return sensor, GT9. When the heat pump is not able to meet the heating requirements, the water heater starts automatically and together with the heat pump provides the required temperature. The hot water is produced in an external double shelled heater. The heating is controlled by a mixing valve controlled by a flow sensor GT4 and an outdoor sensor GT2. This is not an optimal solution for the heat pump because the heat pump works up to its max temperature all year round with inferior efficiency as a result.

Connecting the sensors:

External sensors GT1 and GT2 must always be connected. GT5 if use of a room sensor is required.

Filling the radiator system

Note that the radiator system must have its own expansion vessel. Open the valve between the cold water system and the heating system in short bursts and then close it and note the pressure gauge reading. When the system is full or the right pressure has been reached, vent the system and top it up if necessary.

Filling of heat transfer fluid

The ground coil or well coils must be filled with a mixture of water and heat transfer fluid until a freeze protection level of around -15°C is reached as shown in the following table. Procedure when filling is (compare with the picture on the next page)

• Connect two one inch hoses to both filling valves 1 and 2. One hose has a submersiblepump

(min 6 m³/h) connected at the other end.

• Both hoses are placed in a barrel with a volume of at least 100 litres. The barrel is filled with a

mixture of antifreeze and water. As shown in the table on the next page. Always fill water before antifreeze.

• Open valves 1 and 2, shut valve 3. Start the submersible pump (that is equipped with a particle fil-

ter!), and the system fills with liquid. Note that the first litres in the return pipe are usually contaminated. So collect the first litres in a separate vessel.

• Open the expansion vessel valve until the vessel fills to around 2/3.

• When the level in the barrel has sunk to 25% the submergible pump stops and the barrel fills with the

antifreeze mixture.

• When the system is full and air is no longer coming from the return pipe the system is for a further 30

minute at least. You can start the heat pump’s heat transfer fluid pump to speed up the air venting. Go into manual operation in display 5.3 and start pump P3.

• When venting is ready open valve 3, shut valve 2, and shortly after valve 1. Disconnect the hoses and

the transfer fluid side is ready for operation. Note that a little overpressure in the transfer fluid circuit is beneficial.

Example 200 metres of hose type 40/35 with Brinol gives 200 x 0.29 litres Brinol/ meter = 58 liter Brinol and 200 x 0.71 litres water/ metres = 142 litres water.

Connection of additional heat to oil and electric boiler, operating mode B

When additional heat is from an oil-fired or electric boiler with a mixing valve the wiring to the burner or contactor is connected to terminals N and L on contact T1 via a help relay HR. L1 provides 230Vac. If the electric boiler has an inlet for telecontrol it is connected to the help relay.

Connecting additional heat to electric heater, operating modes A and C

If the additional heat is an electric heater it is connected in the following way: Remove the clamp between L and ELB on contact T1. Mount a new clamp between terminal L3 and ELB on contact T1. Mount the wire on help relay HR to N and L to contact T2. The electric heater’s on/off is connected to the help relay terminals 11 and 14. Concerns both contactors and telecontrol function in the electric heater. Connecting power is set at 2/3 in the 5.2 menu display

If alarm function is required for the electric heater’s overheat protection the clamp between L3 and ELB should not be removed but the clamp between L and ELB. A clamp is mounted instead to ELB from the overheat protection, PLEASE NOTE! Must be phase 3. (see Circuit diagram E series)

General

The heating and heat transfer fluid collector systems must be filled and vented before commissioning the heat pump. Check also that there are no leaks in the systems.

When connecting to an existing water system, check that at least two of the radiators are always open. With underfloor heating, at least two of the circuits must be open. When connecting a fan radiator system, start the fans in the radiators and fully open the valves to the fan radiators.

If the pump stops during testing, refer to the section headed “If something goes wrong”.

Manual testing

You can manually test pumps, valves etc. by going into display 5.3 and choosing manual operation for each function. The heat pump returns to normal operation as soon as you leave display 5.3.

Operation with additional heat only

You may want to use the additional heat in the heat pump before with the heat transfer fluid system is ready. If the heating system is filled and vented you can activate the operation with additional heat only. Go into display 5.4 and select Select. Point at Normal Operation, select Adjust. Turn the knob until the arrow points at Only Additional. Press Save. The additional heat will now heat both the hot water and heating system. Do not forget to restore this function to normal operation.

Go into display 5.4 to choose operation with additional heat only. Note that this is not available in operating mode B with oil-fired boiler.

Starting the heat pump

Connect the mains voltage to the heat pump and press the ON/OFF button on the control panel. Rego600 measures the phase sequence so that the compressor does not go the wrong way, so if you receive a phase sequence alarm the main supply is cut to the heat pump and two of the phases are shifted.

Press “Menu” for 10 seconds to come into the Installer / service menu. I/S should be visible at the top right hand corner.

Heating setting Heating incr/decr can temporarily be set at max. So as to avoid waiting for the heat pump restart timer you can go in to display 5.6 and quick start the heat pump. If the pump does not start press Info to see what the reason is. When the heat pump starts, check the sight glass in the heat pump. On starting there may be bubbles in the sight glass for a minute or so, after which they should disappear. Bubbles present all the time the heat pump is running are a fault symptom. They are probably due to air in the collector hose or insufficient heat transfer fluid. Check that the operational condition of the heat pump corresponds to the information supplied in the Info menu.

Operating mode A is factory setting so most settings are already preset so there are not many you need to check or adjust. WARNING! You must never choose another operating mode the A for the C and E series. The only necessary settings you have to carry out is Ackning the extra sensors in display 5.13 and choosing the output of the electric heater you have fused the heat pump for.

Setting of hysteresis on the hot water temperature. The value measures under and over the set value in 2.3

Mixing valve’s opening is delayed after the boiler starts so that cold water is mixed into the system before the boiler has heated up. You can change the time here.

For safety reasons for the boiler, there is a time delay from the mixing valve not receiving an open signal and the boiler closing down completely. When the boiler closes down completely the additional timer must go down to zero again.

Ramp time open and close is the time the mixing valve shall take to go from closed to fully open and from fully open to closed. In some cases the ramp time can open, 8.3.4 needs to be adjusted to eliminate overexciting the system.

Here you can see if the mixing valve to the oil-fired boiler opens or shuts.

Technical information

Important points to check

During the first period after commissioning you should pay special attention to the pressure levels in the heating system and heat transfer circuit. It might need filling up.

The factory setting of the motor cutout is based on a value under the hot water pressure and stable voltage. Because of the various voltages in the electric network the recommended settings are not always suitable and can therefore need adjusting from time to time. This is best achieved using a clipon ammeter during hot water operation.

For the heat pump to perform at its best, it is important to check the flow on the hot and cold side of the heat pump. Usually, the heat transfer fluid pumps each have a speed selector switch. These must be set correctly for the pressure drop in the systems. A recommended temperature difference over the heat pump on the cold side is between 2-3°C and on the hot side between 7-10°C. The nominal flows specified in Technical Specifications give a difference of 3°C to 7°C at operating mode 0/45°C. You can check this with the help of the sensor temperatures in line three of the control panel.

It is also important that the flow in the radiator system exceeds the flow across the heat pump. If this is not the case, the heat pump flow goes back via the bypass to the heat pump return, which may case the heat pump to trip for high return temperature. The flow through the radiator system must be high enough to ensure that the entiresurface of the radiators is kept hot. This maximises the heat-radiating surface and so keeps down the flow temperature from the heat pump.

After testing, vent the system again and top up with cold water if necessary.
