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.

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.

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.

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!

• The heat pump MCB has tripped

This is what to do:

Reset the MCB by pushing the switch upwards.

If something is wrong

The control unit provides a lot of information about faults and how to remedy them. Rego 600 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

Press “Ackn” when 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 dial to navigate to them.

If you press “Info” and then turn the dial 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 is giving the best possible performance. The description sometimes refers to a heat pump component. You will find these on page 28 for models 14-16 and page 29 for models 20-40.

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 heat transfer fluid circuit.

The installation 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 7): When the heat pump starts, and during rapid temperature changes, you can

sometimes see bubbles in the liquid in the heat transfer fluid 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: If the heat pump has a plastic expansion vessel connected to the heat transfer

circuit the level must not fall below 1/3 (the vessel is mounted outside the heat pump). For 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

Emergency operation, E series

If a fault occurs that you cannot remedy, the plant can operate in emergency mode. In this mode the circulation pump and electric heater are started manually by turning the thermostat wheel on the electric heater. To get both heating and hot water, the 3-way valve must be set at intermediate position (the 3-way valve is built-in in the E series) WARNING! Must not be activated during normal operation.

To reset the alarm: Turn the electric heater thermostat wheel to the required temperature (see following pages, pos 6). Reset the 3-way valve to manual operation in an intermediate position so that the electric boiler can heat both the heating system and the immersion heater. PLEASE NOTE: The control panel alarms for a power failure in emergency operations.

28

Particle filter

• Particle filter: The particle filters, which are connected on both the hot and cold sides of the heat

pump, protect the heat exchangers from dirt. Sometimes 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 filters in the E14 and E16 series are mounted inside the heat pump (pos 1). On the cold side the filter is mounted outside the heat pump.

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. Mark AMA is a general material and work description issued by Svensk Byggtjänst.

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 straight connector.

Maximum lengths

Specified pressure falls and hose lengths are based on heat transfer fluid containing ethanol 30% by volume. Other heat transfer fluids are not recommended because they are sluggish 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 14 has a maximum coil length of 200 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 rate is the same in both coils.

The common 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 pipe. When filling the heat transfer fluid circuit, one coil at a time is filled by using these valves.

Ground water system

Application:

Systems using ground water are equipped with an intermediate heat exchanger to eliminate the risk of 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 30% by volume antifreeze which corresponds to around -15°C.

Exp

36

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 taken 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: A single-phase pump should always be connected with a contactor. It should never be connected to the P3 outlet on the heat pump.

Connecting to the heating system

General

Installation must be carried out by an authorised installer and must follow the current regulations and recommendations of IVT. The pipework must be flushed before the heat pump is connected to protect the heat pump from contaminants.

Please note that the connecting instructions are only outlined sketches. For more detailed descriptions please see IVT’s system manual for properties. See IVT’s homepage http://www.ivt.se/.

Function E14-E25, work tank and coil tank

Overview

The heating system is mainly heated by the heat pump, which creates the required temperature through intermittent operation (liquid condensing). If the heat pump is not sufficient then the built-in electric boiler provides supplementary heat in three steps.

Heat from the heat pump

The required temperature for the heating system (TT1) is set on the heat pump as an outdoor curve. The heat pump starts when TT1 falls below the set temperature by 2.5°C and stops when TT1 exceeds the set temperature by 2.5°C (adjustable). The temperature to the heating system can be controlled by either the heating system flow or return. The best function is available when TT1 is mounted on the flow pipe, which requires that the heat pump hysteresis is increased from 5°C to 10°C (Menu 1.4).

Hot water

If the temperature is too low in the coil tank (TT3) the mixing valve changes over to the coil tank and changes back to the heating system when the coil tank has become warm. The heat pump is allowed to work for max 30 minutes to the coil tank if there is a heating demand. After which the heat pump must work at least 20 minutes to the heating system or until the heating demand is met.

Electric water heater

If the heating system temperature (TT1) falls under the set temperature by more than half hysteresis (2.5°C) of set time (60 minutes) the electric water heater is activated. When the heater is active and TT1 falls below the set temperature, the heater output is increased in 3 steps in 20 minute intervals. If TT1 exceeds the set temperature, the heater output is reduced in 3 steps in 3 minutes. The electric water heater is blocked at the same time as the heat pump stops when the heating demand is met.

Summer disconnection

The heating system and circulation pump G1 (P1) stop when the outdoor temperature exceeds 18°C (between 10°C and 30°C). The circulation pump is exercised for 3 minutes every third day.

For information regarding other controls see description of Rego 600.

The required temperature for the heating system (TT1) is set on the heat pump as an outdoor curve. The heat pump starts when TT1 falls below the set temperature by 2.5°C and stops when TT1 exceeds the set temperature by 2.5°C (adjustable). The temperature to the heating system can be controlled by either the heating system flow or return. The best function is available when TT1 is mounted on the flow pipe, which requires that the heat pump hysteresis is increased from 5°C to 10°C (Menu 1.4).

Hot water

At a low temperature in the coil tank (TT3), the 3-way valve changes over to the coil tank and changes back to the heating system when the coil tank is warm again. The heat pump is allowed to work for max 30 minutes to the coil tank if there is a heating demand. After which the heat pump must work at least 20 minutes to the heating system or until the heating demand is met. The temperature in the water heater increases by set intervals to 65°C.

Electric water heater

If the heating system temperature (TT1) falls under the set temperature by more than half hysteresis (2.5°C) of set time (60 minutes) the electric water heater is activated. When the heater is active and TT1 falls below the set temperature, the heater output is increased in 3 steps at 20 minute intervals. If TT1 exceeds the set temperature, the heater output is reduced in 3 steps in 3 minutes. The electric water heater is blocked at the same time as the heat pump stops when the heating demand is met.

Summer disconnection

The heating system and circulation pump G1 (P1) stop when the outdoor temperature exceeds 18°C (between 10°C and 30°C). The circulation pump is exercised for 3 minutes every third day.

Overview

The radiators are first heated by the heat pump, which creates the required temperature through intermittent operation (liquid condensation). If the heat pump is not sufficient the oil-fired boiler provides supplementary heat.

Heat from the heat pump

The required temperature for the heating system (TT1) is set on the heat pump as an outdoor curve. The heat pump starts when TT1 falls below the set temperature by 2.5°C and stops when TT1 exceeds the set temperature by 2.5°C (adjustable). The temperature to the heating system can be controlled by either the heating system flow or return. The best function is available when TT1 is mounted on the flow pipe, which requires the heat pump hysteresis to be increased from 5°C to 10°C (Menu 1.4).

Hot water

If the temperature is too low in the coil tank (TT3) the mixing valve changes over to the coil tank and changes back to the heating system when the coil tank has become warm. The heat pump is allowed to work for max 30 minutes to the coil tank if there is a heating demand. Then the heat pump must work at least 20 minutes to the radiators or until the heating demand is met.

Oil-fired boiler

If the heating system temperature (TT1) falls under the set temperature by more than half hysteresis (2.5°C) of set time (60 minutes), the oil-fired boiler is activated. When the oil-fired boiler has been on for 30 minutes and TT1 falls below the set temperature, the mixing valve SV1 opens from shut to fully open in twenty minutes. If TT1 falls below the set temperature, SV1 closes from fully open to closed in 3 minutes. The oil-fired boiler is blocked again when SV1 has not opened anything for 60 minutes.

Summer disconnection

The heating system and circulation pump G1 (P1) stop when the outdoor temperature exceeds 18°C (between 10°C and 30°C). The circulation pump is exercised for 3 minutes every third day.

Electric boiler

If the heating system temperature (TT1) falls under the set temperature by more than half hysteresis (2.5°C) of set time (60 minutes) the electric boiler is activated. When the electric boiler is active and TT1 falls below the set temperature, the boiler output increases from zero to full output in 20 minutes. If TT1 exceeds the set temperature, the output is reduced from full output to zero in 3 minutes. The electric boiler is blocked at the same time as the heat pump stops when the heating demand is met.

Summer disconnection

The heating system and circulation pump G1 (P1) stop when the outdoor temperature exceeds 18°C (between 10°C and 30°C). The circulation pump is exercised for 3 minutes every third day.

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.

The procedure when filling is: (compare the picture on the next page)

• Connect two one inch hoses to both filling valves 1 and 2. One hose has a submersible pump (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 mix-

ture of antifreeze and water. The mixture 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

filter!), 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 run for at least

30 minutes. You can also start the heat transfer fluid pump to speed up the air venting. Go into manual operation in window 5.3 and start pump G3 (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.

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 “On” and 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.

Commissioning operating mode A (D and E series)

Connect the mains voltage to the heat pump and press the ON/OFF button on the control panel. Rego 600 measures the phase sequence so that the compressor does not run in the wrong direction, so if you receive an 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.

Heat setting Heat incr/decr can temporarily be set to max. To avoid having to wait for the heat pump restart menu you can go 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. When starting there may be bubbles in the sight glass for a minute or so, after which they should disappear. If there are bubbles present all the time the heat pump is running, this is 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 the factory setting so most settings are already preset so there are not many you need to check or adjust. The only settings you need to make are Ackning the extra sensors in display 5.13 and choosing the output of the electric heater you have fused protected the heat pump for.

56

Always check that operating mode A is set.

If you have connected any of the external sensors T3 (GT3), T4 (GT4) or T5 (GT5) you must acknowledge them so that Rego 600 memorises them.

Setting maximum output to be used by the electric heater. You can choose 1/3, 2/3 or 3/3. NOTE! The heat pump must be fused protected for the set ouput. Factory setting is 2/3. See the description below in technical specifications.

Connect the mains voltage to the heat pump and press the ON/OFF button on the control panel. Rego 600 measures the phase sequence so that the compressor does not run in the wrong direction, so if you receive an 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.

Go into display 5.1 and choose operating mode B. This is described further down in the text.

Heat setting Heat incr/decr can temporarily be set to max. To avoid having to wait for the heat pump restart menu you can go 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. When starting there may be bubbles in the sight glass for a minute or so, after which they should disappear. If there are bubbles present all the time the heat pump is running, this is 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.

There are always some settings you have to check or adjust and some you might need to change if they require another setting than the factory setting.

Displays you must always check

Choose operating mode B so that Rego 600 memorises the operation with oil-fired boiler and mixing valve.

If you have connected any of the external sensors T3 (GT3) or T5 (GT5) you must Ackn them so that Rego 600 memorises them.

When you use a mixing valve to the oil-fired boiler it is important to set the running time of the motor. The time it takes for the mixing valve to go from closed to fully open. It is often marked on the mixing valve motor.

Setting the hysteresis for the heat pump on and off switching on the return sensor radiator T1 (GT1). A low value gives closer intervals between start and stop.

Setting the temperatures in the hot water cylinder’s outer shell. Note that the temperature does not correspond to the temperature in the hot water cylinder itself. Set too high and the heat pump can shut down on a high return or high pressure switch.

Setting of hysteresis for 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 on 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 takes 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

Table of factory settings

The table shows the factory settings of all the settings that can be changed by the installer.

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 during hot water charging and a stable voltage. Because of the fluctuating voltages on the mains supply 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. 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 cause the heat pump to trip for high return temperature. The flow through the radiator system must be high enough to ensure that the entire surface 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.
