2 Product data

With the help of the HPC400 (Procontrol 600) control unit it is easy to control the heat pump. You select the required room temperature in your home by turning the menu dial. The thermostat valves on the radiators should normally be fully open, but can be adjusted if it gets too cold or hot in one room. The optimised operating mode ensures the efficient use of energy. Heating and cooling are controlled to ensure optimum comfort with the minimum possible consumption of energy. The heating of hot water can easily be set, and then requires few adjustments.

2.1 Functions

The number of functions and the menu structure on the control unit depend upon how the system is built up.

• Settings for different heating and cooling circuits are only accessible if two or more heating/cooling circuits are installed.

• Information on the solar heating system is only shown if a solar heating system is installed.

There are references to indicate that functions are related to the structure of the system where this is relevant. The range of settings and default settings vary, depending on which system has been installed and can deviate from the information in these operating instructions.

Consult your installer if you have any additional questions.

2.2 Functionality of the control unit

Cooling is disabled in the UK model to comply with the regulations for RHI.

The control unit can control up to four heating/cooling circuits. In heating mode the control unit works with one of the main control modes in each heating circuit. Depending on your requirements, the installer selects one of these and sets it.

The main control modes for heating are:

• Outdoor temperature controlled: – Control of room temperature in relation to outdoor

temperature

– The control unit adjusts the flow temperature

according to a simplified or optimised heat curve.

• Outdoor temperature controlled with input from room temperature:

– Control of room temperature on the basis of outdoor

temperature and measured room temperature. The room unit actuates the flow temperature on the basis of the measured and required room temperature.

– The control unit adjusts the flow temperature

according to a simplified or optimised heat curve.

2.3 Operation after power failure

In the event of a power failure, or periods with disconnected heat source, no settings are lost. The control unit starts again when the power returns. It may be necessary to redo the settings for the time and date. No other settings are necessary.

For outdoor temperature controlled adjustment with input from room temperature the following applies: The thermostat valves in the reference room (the room where the room unit is installed) must be fully open.

5.2 Adjust settings for automatic operation of house heating

Cooling is disabled in the UK model to comply with the regulations for RHI.

Menu: Heating/Cooling

Optimised operation normally produces the highest comfort with the largest possible energy savings. A constant temperature can be set in cooling mode.

Optimised operation for each heating circuit is active with the default settings

Heating circuit 1 – 4

If several heating circuits are installed and configured, the settings for heating circuits 1 – 4 are changed in the same way as in systems with one heating circuit. The changes only apply however to the selected heating circuit. If the heating circuits are given names that are easy to distinguish, this considerably simplifies the selection of the correct heating circuit.

5.2.1 Adjust Time program for automatic operation of house heating

The time program for house heating is only active if automatic mode is active ( chapter 4.2, page 9).

This is how you can set the same break points for several weekdays:

▶ Set break points for a group of several days, e.g.

Mon-Sun or Mon-Fri.

▶ Adjust the time program for the individually deviating

weekdays during Monday – Sunday (detailed description  table 12, page 16).

Menu: Time program

The time programs automatically switch from one mode to another at fixed times. The control unit has two time programs for each heating circuit. You can program two break points per day, with their own operating mode. The default settings for the time programs result in reduced heating during the night.

Operation without a time program results in the highest possible energy saving.

If the settings, temperatures or time program break points do not match your requirements you can adjust the time program. Talk to your installer if you do not want to heat the house during the night. He can also set the temperature reduction mode.

The following table shows how to activate and select a time program for house heating.

Menu options Description Activate time

program

When automatic mode is activated the control unit applies this selected time program (My time program 1 or My time

program 2).

My time program 1

6 break points can be set for each day or each group of days. Each break point can be allocated one of the two modes in automatic mode. The shortest possible period between two break points is 15 minutes.

Reset prog. Here My time program 1 can be reset to

the default settings.

Rename heating circuit

The name of the selected heating circuit can be adjusted here (this function is only available if more than one heating circuit is installed). This simplifies the selection of the correct heating circuit, e.g.“floor heating” or“loft”. The names are preset with Heating circuit 1 – 4 ( table 13, page 18).

Rename time program

It is possible to change the name of the time programs in the same way as the heat circuits. It simplifies the selection of the correct time program to give the programs names like“family”or“night shift”.

5.7 Adjust settings for hybrid system

Menu: Hybrid system In a system with a hybrid system there are two different heat sources. A heat source that utilises regenerative energy generates heat from geothermal energy, from the air, from biomass, or from solar energy. Heat is also supplied from a conventional source, e.g. oil or gas.

If a hybrid system is installed in the system the following menu is shown Hybrid system.

In this case the hybrid system consists of a heat pump and a separate gas or oil heating source.

Depending on the actual circumstances and heating requirements, either the heat pump or the gas/oil heating source produces the best price-performance ratio.

Controlling the heat pump controls the actual output data of the heat pump with the set energy price ratio and whether the heat pump or gas/oil heating source is more beneficial from the perspective of cost. Either the heat pump or the gas/oil heating source is used, depending on the result.

In the menu Hybrid system > Energy:price ratio the energy ratio between electric power and solid fuel can be regularly adjusted to the actual price structure.

The cost ratio is calculated according to the following formula:

e.g.

• Electricity costs: 24 cent/kWh

• Gas/oil costs: 8 cent/kWh

This ratio must be given via the menu Hybrid system > Energy:price ratio.

The setting of the price ratio is made by dividing the price of electricity with gas

7 Energy saving tips

Heating/cooling set low

• Use the optimised mode. Set the required room temperature to your personal comfort level. The heat pump saves most energy if it works continuously.

• Open the thermostat valves completely in all rooms. Increase the temperature on the control unit only when the required room temperatures has not been reached after a long period. Only close the thermostat valve in a room if it gets too hot just in that room.

• If there is a room unit in the system the room temperature can be optimally controlled. Avoid the effect of induced heat (e.g. from sunlight or stove). Otherwise there can be unwanted variations in the room temperature.

• Do not place any large objects directly in front of radiators, e.g. a soffa (minimum 50 cm gap). The heated or cooled air will otherwise not be able to circulate and heat up or cool the room.

• Do not set the temperature too low to start the cooling. Cooling of the home also consumes energy.

Air properly

Open the windows completely for a short time instead of allowing them to stand ajar. If windows are left ajar heat dissappears continuously from the room without the air in the room become much better. Close the thermostat valves while airing the room.

Heating of hot water according to need

• Use the time program for automatic operation of heating hot water.

• Set the lowest possible hot water temperature. This saves a lot of energy, without significantly reducing hot water comfort.

Common questions

HMC300 – 6 720 813 192 (2014/10)

8 Common questions

Why do I have to set a set point value for the room temperature even though the temperature is not measured?

When you set a set point value for the room temperature you change the heat curve. This also changes the room temperature, because the temperature in the heating system changes.

Why do the radiators get too hot with a high outdoor temperature?

Even in summer mode radiators can heat up for a short period in special circumstances, such as when the circulation pump starts automatically at a certain interval to prevent it "jaming" (blocking). If the circulation pump should by chance start immediately after the heating up of hot water the residual heat that is not used is moved away via the heating circuit and the radiators.

Why does the heat pump work at night if the heating is negligible or very little?

There can be different reasons for this. It depends on which setting your installer has made for temperature reduction.

• Reduced mode: The heat pump works even when the heating requirement is less to achieve the set room temperature, even if it is low.

• Outside temperature threshold and Room temperature threshold: the heating system switches automatically on if the measured temperature drops below the set value. The heat pump will then start as well.

• Protection from freezing: The heating mode is also used to avoid the system freezing if the outdoor temperature drops.

Why is the extra heat source used when the time program switches from lowering to heating?

The output of the heat pump is limited. If the required room temperature suddenly increases then the extra heat source must also produce heat, even if no extra heat source is needed when the temperature is the same. This is why the time program is not a good choice to save energy.

The measured room temperature is higher than the required room temperature. Why is the heat source working anyway?

The heat source can heat up hot water.

Your heating system can be set to 2 possible control modes ( chapter 2.2, page 4).

With outdoor temperature controlled adjustment (and with the effect of the room temperature) the heat source can also work if the measured room temperature is higher than the set room temperature. This also serves to heat adjacent rooms, which do not have their own room unit, sufficiently.

Why does the house heating not switch off even though the outdoor temperature has reached the threshold temperature set for disconnection in the summer?

Disconnection for the summer on the basis of the outdoor temperature takes the thermal inertial of the building and its mass (equalisation of temperature differences due to the structure of the building) into consideration. There is therefore a delay of several hours before disconnection takes place.

Optimised mode

In optimised mode the automatic mode (time program for house heating) is not active and the system provides heating continuously according to the temperature set for optimised mode.

Reference room

The reference room is the room in the home where a room unit has been installed. The room temperature in this room acts as the control variable for the assigned heating circuit.

Switching time

A certain time at which the heating system starts to heat or hot water is produced, for example. A switching time is a component of a time program.

Temperature of an operating mode

A temperature that is assigned to an operating mode. The temperature is adjustable. See the explanations on operating mode.

Thermal disinfection

This function heats up the hot water to a temperature in excess of 65 °C. This temperature is sufficient to kill off pathogens (e.g. legionella). Observe the anti-scalding safety instructions.

Holiday program

The holiday program enables the settings that would ordinarily be applied to be interrupted for a number of days. After the end of the holiday program, the programming unit resumes operation with the settings that would ordinarily be applied.

Flow temperature

The temperature that the heated water maintains in the central heating circuit, from the heat source to the heating surfaces in the rooms.

Water heater

A water heater stores large volumes of heated tap DHW. Thereby, sufficient DHW is available at the draw-off points (e.g. taps). This is a prerequisite for longer hot shower.

Time program for the heating system

This time program ensures automatic changeover between operating modes at defined switching times.

Time program for hot water heating

This time program means that the system automatically switches between the modes DHW, DHW reduced and Off at fixed break points. It can be connected to the time program for house heating ( chapter 5.3.2, page 20).

Time program for circulation

This time program ensures automatic operation of the DHW circulation pump at defined switching times. Linking this time program to the time program for hot water is recommended.

Hot water circulation pump

A hot water circulation pump allows the hot water to circulate between the hot water heater and the taps. In this way you have quick assess to hot water at the taps. The circulation pump can be controlled with a time program.
