1.1. Heat Pump Control Board

The heat pump control board is designed to control the heating of the water in one or two heating circuits, heating of the domestic hot water, heating of the pool water and to control the solar heating system. This board is equipped with the necessary number of inputs for sensors used to measure temperature and pressure and to indicate the exceeding of the permitted values. To control the compressor and auxiliary heater contactor, heat exchanger fan, circulation pumps, and mixing and switching valves of the heating circuits, the control board contains 18 relays that can switch voltage 230V with a maximum current of 2A. In addition, the board can control three stepper motors of electronically controlled expansion valves and it has four voltage outputs 0-10V to regulate the speed of evaporator fan and circulation pump. Part of the control board is a switched-mode power supply for powering the board and the other circuits of the heat pump. The power supply contains control circuits to check the mains voltage and correct phase sequence, and to distinguish between low or high price tariff for the supplied electricity. The board can communicate with a superior system via RS485 serial interface. On request it can be equipped with a LAN module for remote management and control via Ethernet and can also be extended by a GSM module for communication via a cellular network. Dimensions of the control board are 267 x 125mm; along both longer sides are terminals for connecting input/output wires. Outputs dedicated to switching mains voltage 230V, power input terminals 3x400V/50Hz for powering the board and a terminal for a price tariff signal from an electricity meter are located on one side of the control board; signal inputs/outputs are on the other side of the board. The connection with the external heat pump circuits is made through three separate terminal blocks, which are also located under the top cover of the heat pump; no wires are connected to the control board when mounting the heat pump at the user site.

1.2. Heat Pump Control Panel

The control board is equipped with a simple control panel located on the plastic cover of the heat pump indoor unit. The control panel contains a backlit alphanumeric display with 2 x 20 characters; to select menu items and to set them up a bi-directional dial knob with confirmation button in its centre is used. The control panel is mounted on a support plate of stainless steel coated with a cover plate. The connection between the control panel and the heat pump control board is established via a flat cable.

Fig. 3. Heat pump control panel After turning on, the heat pump performs a self-test and a initial message is displayed on the control

panel display and a red LED lights during this test. If you have already set the real time clock and the heat pump is not in an error state, the initial message is followed by displaying the status of the main parts of the heat pump and the current time on the top line of the display and the selected temperatures on the bottom line of the display. This is the default state, i.e. the display in the standby mode before any intervention of the operator.

The display can show two lines, each of 20 characters. The first row that shows the heat pump status and the current time in hours and minutes is so called display status line. In the case above, the compressor (character C), the fan (character F) and the pump (character P) are off (the symbol OFF). The bottom line shows the selected temperatures in C. In the case above, it is the ambient temperature AT and the heat pump evaporator temperature CT. The line shows two temperatures; it is possible to display up to 16 temperatures. Using the dial knob you can shift the displayed lines in both directions and sequentially check all the measured temperatures. Displaying up to 16 temperatures and their placement in the individual lines of the display is given by heat pump display settings, which can by configured by user. Besides that, the last five lines show the heat pump operating parameters; their are displayed in a fixed format and designed to check the heat pump performance.

If the real time clock has not been set yet or in case of backup battery failure after the power is turned off, the error message is displayed after the heat pump is turned on and the cursor blinking on the "Hour" position indicates the sequence for setting the clock.

Use the dial knob to set the hours; turn it to the right to increase the value or turn it to the left to decrease the value. After setting the hours, press shortly the confirmation button to set the minutes. After setting the minutes in a similar way, press shortly the confirmation button to set the seconds.

3. Heating

Heating menu is designed to start or stop the heating mode of the heat pump. This menu contains no

adjustments and is accessible only when the heat pump is not in an error state. If an error is detected when entering the main menu, only the Setup and Comfort options are accessible and the message HP error, the number of errors and the error specification are displayed in the main menu. See the Error list on page 61 for details. In case of a compressor failure, an evaporator failure, a refrigerant leakage or other failure of the heat pump, it is possible to provide an emergency heating and domestic hot water heating using an auxiliary electric heater (bivalent source). To run in the emergency mode, the auxiliary electric heater, the circulation pump and the heat exchanger must be operational. To switch the heat pump into the emergency mode, it is necessary to change the Emergency mode settings from NO to YES in the Heating settings menu (see chapter 7.1.1. on page 28). With Emergency mode set to YES, Heating option is accessible in the main menu even when error is detected, and you can run the heat pump in the Emergency mode.

3.1. Heating in Normal Mode

According to your settings, the heat pump can heat the domestic hot water, the heating water for one or two heating circuits and the water in the pool. The heating control method depends on the heating mode - heating can be controlled according to the outdoor temperature (equitherm control, weathercompensated control), according to the temperature in the reference room or in the Emergency mode. The heating mode can by set in the menu Heating settings. Please see the chapter 7.1.1. on page 33 for description of the different heating modes. When the equitherm control is selected, the required heating water temperature in heating circuits is determined by equitherm curves according to the outdoor temperature. The control electronics sets the heating water temperature according to the outdoor temperature to ensure a desired thermal comfort and to avoid unnecessary overheating of the building. The shape of the equitherm curves depends on the heating system and the thermal insulating properties of the building. For this reason, you may need to adjust the preset equitherm curves during the first heating season. The equitherm control controls the heating water temperature, therefore the

time and manual temperature corrections regulate the heating water temperature. When the control according to the temperature in the reference room is selected, the equitherm controls is

also partly used to ensure the adequate response of the heating to the outdoor temperature, but the goal is to achieve the required air temperature in the selected reference room. Therefore, in this case, the time and manual temperature corrections adjust the air temperature in this room. When the status line is displayed, press the confirmation button to enter the main menu. The bottom line displays Heating menu which allows you to start the heat pump.

After opening this menu, Heating moves to the top line of the display and if the pump is switched off, the display shows:

The top line of the display shows the status line. Individual symbols for the compressor (C), the evaporator fan (F) and the circulation pump (P) are followed by symbols (dashes) which rotate in clockwise direction when the related parts run normally. At the high tariff of the supplied electricity, the characters C, F and P are uppercase letters, while at the low tariff they are lowercase letters. The following indication TE1 determines the actually heated circuit (this can be TE1, TE2, DHW or POOL), the character E means the Equitherm control (R means the Reference room) and D0 means the active Daily temperature correction according to the register 0 (W0 to W3 are Weekly temperature corrections according to the registers 0 to 3). While waiting for the start of the temperature correction by date, symbols for appropriate heating time correction (D0 to D3 or T0 to T3) and symbol DA indicating the

5. Manual Defrosting of the Heat Pump Evaporator

Due to the low temperature of the expanding refrigerant in the evaporator, a frost is gradually build up on the evaporator fin when the heat pump operates at low ambient temperatures. This causes the deterioration of the heat transfer between the surface of the evaporator and the ambient air. The control electronics of the heat pump continuously evaluates this situation and, if necessary, starts the automatic defrosting of the evaporator. During the defrosting, the four-way valve is switched to deliver the hot refrigerant from the compressor outlet to the evaporator and the frost is melting rapidly. If necessary, use the Defrost menu to manually defrost the evaporator, even if the conditions for automatic defrosting are not met. The Defrost menu contains no adjustments and is accessible only when the heat pump is not in an error state. If an error is detected when entering the main menu, only

6. Comfort

This menu is designed for a quick correction of the temperature in the heated building without changing the heat pump settings. Depending on the selected mode of the operation, you can adjust the heating water temperature in the equiterm control mode or you can adjust directly the required air temperature in the reference room in the reference room mode.

6.1. Quick Temperature Adjustment in the Equitherm Control Mode

In the equitherm control mode, the heated water temperature depends on the outdoor temperature. In addition, the heated water temperature is adjusted by daily and weekly temperature corrections. The set parameters, especially during the first heating season, may not be suitable and should be adapted to the building characteristics and user requirements. The Comfort menu allows you to shift heated water temperature compared to equitherm curves with possible time corrections in one or two heating circuits. After confirming the set shift, the corrected equitherm curve is adjusted accordingly. This shift of the corrected equitherm curve is valid until it is reseted in the Comfort menu or until reaching such date and time when the shift of the corrected equitherm curves set in the Comfort menu is cancelled. The dependence between the change of the water temperature and the air temperature in the building will depend on the characteristics of the building and the outdoor temperature. At low outdoor temperatures it will be necessary to set a greater shift of the heating water temperature in order to achieve the same shift of the internal temperature. After verifying the set correction of the heating water temperature it is possible to adjust the equitherm curves. When the status line is displayed, press the confirmation button to enter the main menu and use the dial knob to select the Comfort option.

is displayed for 2 seconds and then the display returns one level back in the menu.

6.2. Quick Temperature Adjustment in the Reference Room Mode

When the heating temperature is controlled according to the reference room temperature, the temperature corrections directly regulate the air temperature in the reference room. This means that in the heating mode according to the temperature in the reference room you can't use the same timetemperature correction as in the heating mode with equithermal control, where corrections of the temperature adjust the heating water temperature. It is necessary to prepare two sets of the temperature correction in the individual registers; one for equitherm regulation and one for regulation according to the reference room temperature. These registers sets are switched automatically when the heating mode is changed. The Comfort menu in the reference room mode looks like

Use the dial knobe to set the shift of air temperature in the reference room in the range from –4,9 to +4.9C. Confirm the settings by long press of the confirmation button. The display shows

Temperature Correction of the Heating Operation

This menu allows you to adjust the temperature shifts in the building depending on the time of the day, on the day of the week or on the date. According to the stored corrections and the selected control mode, the control electronics adjusts the temperature of the water in the heating circuits if the equitherm control mode is used or it adjusts the air temperature in the reference room if the reference room mode is used. This allows to reduce the temperature for example during the night time, in case of absence of people in the building (leaving for work, vacation, etc.). To save the daily and weekly correction, up to 4 temperature correction registers can be used. Each register can contain up to 8 daily and 56 weekly corrections. To select the current correction register, the Current register option is provided; all corrections made will be stored in the selected register.

The temperature corrections of the heating water temperature used in the equitherm control mode and the temperature corrections of the air temperature used in the heating control mode according to the reference room are stored separately in two sets of registers, which are

Setting the Equitherm Curve for Heat Pump Heating Control

To achieve the maximum thermal comfort in heated rooms, the heat pump adjusts the heating water temperature depending on the outdoor temperature. To express the dependence of the heating water temperature on the outdoor temperature, equitherm (heating) curve is used. You can set the heating curve for one or two heating circuits. Each curve is made up of four points that can be adjusted over a wide range to achieve the required thermal comfort. Each point is specified by the outdoor air temperature Tai and the associated heating water temperature Twa. This means that the outdoor temperature is always assigned to the heating water temperature. For each value of the outdoor temperatures, corresponding temperature of heating water is calculated using the four specified points of the equitherm curve and the linear approximation. Shape of the curve is shown in Figure 4.

The mains status consists of two hexadecimal characters. If all the phases have the nominal voltage and are connected in the correct sequence, the first character is 0 and the second character is 0 at the low tariff or 1 at the high tariff. If the first character other than 0, there is some voltage out of tolerance or incorrect phase sequence. To decode the status, it is needed to convert the hexadecimal number into the binary format, where 0 = OK or the low tariff and 1 = incorrect voltage, phase sequence or a high tariff.

 U means that the voltage of the corresponding phase is higher than the allowed tolerances tolerance;i  U means that the voltage of the corresponding phase is lower or zero. Example: status 41 means the missing phase T

Other settings are accessible to the user of the heat pump and can also be protected against tampering by optional user password. Menu User Password allows to enable/disable the password and change it. When the status line is displayed, press the confirmation button to enter the main menu. Use the dial knob to select the Setup option on the bottom line.

After opening this menu, Setup moves to the top line of the display. Use the dial knob to select the User Password option on the bottom line.

After opening this menu, User password moves to the top line of the display, and depending on the use of password, the display shows Password: On or Password: Off.

After confirmation:

Cursor is blinking on the position of the first character. Use the dial knob to set the first character of your password and shortly press the confirmation button to set the next character. Set the next character in a similar way and repeat this to set all six characters of the password After setting the last character, press the confirmation button for a longer time to save the password. The prompt appears:

Press the confirmation button to save the settings. The confirmation message Saved OK briefly appears and then the display returns one level back.

Use the dial knob to set the other settings or select and confirm the Return option to exit this menu. If the user password is enabled, it is required each time you access the Setup menu of the heat pump. If you forget the password, you can disable its use by turning off the heat pump and then turning it on again while holding the confirmation button. You need to hold the confirmation button all the time while initialization of the heat pump is being performed, i.e. until the display enters the default state.

Description

Possibly causes

Repair method

High condensing pressure at compressor outlet

Excessive speed of running pump for heating the water to high temperature

Service intervention is needed. If the error is repeating when the water is heated to a high temperature then reduce the speed of running pump

Too low evaporating pressure at the compressor inlet

Sensor failure, EEV failure or evaporator fan failure

Service intervention is needed.

Protective thermal compressor relay activated

Long-term increasing of compressor input, activated relay will remain disconnected until operator intervention

Service intervention is needed.

Too low temperature of inlet water of heat pump

Sensor failure, incorrect limits for heating (or cooling) of the water

Service intervention is needed, correct temp. limit for heating (or cooling) of the water. The pump due to frost protection can not operate with water at a temperature below 7°C

Outlet water temperature out of limits, it is too low or too high

Sensor failure, incorrect limits for heating (or cooling) of the water

Service intervention is needed, correct temperature limit for heating of the water. The pump due to frost protection can not operate with water at a temperature below

7°C, and can not heats the water to a temp.

higher than 65°C

Heat pump water flow too low

Low or no water flow

Check that the water circuit is bled, the closures are opened and the pump speed is set to a reasonable value that can depend on the specific implementation of plumbing

Too high temperature at the compressor outlet

Sensor failure, EEV failure at EVI heat exchanger or EEV incorrect setting

Check the ET sensor. If the error occurs repeatedly when heating of the water to higher temperatures, check the EEV at EVI heat exchanger and setting of its control parameters.

Failure of threephase power

Voltage out of tolerance, interrupted connection of phase, incorrect phase order

Service intervention is needed

Incorrect checksum for the current language selection

It is checked when powering heat pump, error occurs when a data breach in the working memory

When this error is detected, first stored language version is automatically loaded from the non-volatile memory to the working memory, and this is always English

Incorrect list of languagesin a non-volatile memory

It is checked when changing the language version, the error occurs when the data error in non-volatile memory

Service intervention is needed, uploading of a new set of languages from an external computer via RS485 serial interface will be necessary

Wrong language selected

It is checked when changing the language version, the error occurs when the data error in non-volatile memory

Service intervention is needed, uploading of a new set of languages from an external PC via serial interface will be necessary

8. Summary of heat pump errors

When the status bar is displayed pressing of the button shows the main menu. If heat pump error is detected when entering the main menu, an error message will display codes up to five errors. Meaning of detected errors is shown in the following table.
