User interface and parameter visualisations

The main user interface is represented by a LED panel with capacitive keyboard (touch keys); the visualisations are arranged in three menus:

• READINGS menu (key (C) Fig.1)

Containing the information (visualisation mode only) relating to current unit functioning.

- SETTINGS menu (key (D) Fig.1)

Containing all the parameters that the user can modify according to system requirements; these parameters are grouped together in various sub-menus:

- USER menu (Password 000);

- INSTALLER menu (Password 030);

- ELECTRIC HEATER menu (Password 001);

• ALARM log (key (E) Fig.1)

The alarm log records unit error and/or malfunctioning conditions (whether alarms or pre-alarms).

During normal functioning, the monitor visualises the last parameter modified; if no other keys are pressed for at least 5 minutes, the monitor activates the screensaver mode (this function can be set via the parameter (i) in the INSTALLER menu).

To display parameters and/or readings, 4 fi gures are used; the fi rst is the indicator i.e. a number allowing the user to know which parameter or reading he is visualising (Fig.3).

Readings menu

To access the readings menu, press the key in (Fig.4); once the readings menu has been accessed, the monitor will display the readings index and a 3-character string that identifies it; the string will be displayed for one second, after which it is replaced by the value of the reading itself. To move on to the next reading, press the key in (Fig.5); to go back to the previous one, press the key in (Fig.6). Every time you pass from one reading to another, apart from the change in the index value you will also see (for one second) the string identifying

the current reading (it is possible, however, to identify any reading via the value of the indicator, comparing it with the table below).

Enabling domestic water

Index - String	MIN value	MAX value	Parameter function
	0	1	In the heat pump models, there is the possibility to produce hot water for domestic use; this production has its own modifiable setting and its own band (parameters E, F user menu); with this parameter you can make parameters E and F visible and usable. Remember that to guide the domestic water production request, once the function has been activated you must use digital input ID6 (marked on the electric card enclosed with the unit as TWS). Remember also that setting this parameter with a value of:• 1, you ENABLE the domestic water function• 0, you DISABLE the domestic water functionThe CLOSED status of the clamp means the domestic water function is ACTIVE. This function is available from software version 3.7 (the software version is visible as a reading, with index E). The minimum compressor functioning time, and the defrosting time, take priority over the production of domestic water. From software version 4.2, when domestic water is activated the adjustment is automatically set on the basis of the output temperature, regardless of the value of the parameter (0) in this menu.

Managing the electric heater

The units with moducontrol offer the possibility to manage an electric heater; this heater can be managed in different ways:

• supplementary (the simultaneous use of the heat pump and the electric heater);
- anti-freeze, or replacement (the heat pump compressor is switched off and the electric heater alone is activated); The operational specifications of both modes are shown in the diagrams below.

The choice of supplementary or replacement mode depends on the external air temperature, and in case this falls below the threshold indicated in the relative diagram.

WARNING: all parameters referred to in the chart alongside are contained in the electric heater menu, shown on the next pages.

Alarms summary table

The units envision two types of malfunctioning signals:

• Pre-alarm
• Alarm

The first type is indicated by the flashing of the red LED on the display, successive pressing of the bell key allows to display the list of alarms (with index and cause indicated in the table below). A pre-alarm remains such for 60 seconds: if after this time the condition that caused the pre-alarm has not disappeared, the same becomes an alarm. The alarms are displayed in the same way as the pre-alarms,

except for the switch-on of the fixed red LED. Before rearming the unit, it is recommended to contact the after-sales service. To rearm the unit, switch it off and back on again using the stand-by key.

ATTENTION:

The pre-alarms can become alarms when:

• A time has passed longer than or equal to 60 seconds, in the pre-alarm condition.
• The maximum number of pre-alarms in one hour (five) has been exceeded. In this case, every successive pre-alarm will be displayed directly as an alarm, and as such, will stop the machine until the reason for the same is solved.

Code Alarm	Code Pre-alarm	Causes Notes
1 101		Compressor magnet circuit breaker	This signal intervenes if the contact relative to the magnet circuit breaker switch protecting the MTC compressor opens (Table 2, contact ID1, clamps M7.1 - M7.2, normally closed)
		Fan magnet circuit breaker
		Pump magnet circuit breaker
2 102	Fan magnet circuit breaker		This signal intervenes if the contact relative to the magnet circuit breaker switch protecting the MTV fans opens (Table 2, contact ID6, clamps M7S.3 - M7S.4, normally closed) This code is displayed only if the board is used as a board spare part with SW up to version 3.6.
3 103	High pressure switch		This signal DOES NOT give the state of the high pressure switch itself but of the compressor switch. The high pressure switch operates directly on the compressor switches. If the board commands compressor switch-on and the switch does not become active after 3 seconds, this signal occurs. This alarm can also be caused by an operating defect of the return relay from the compressor switch to the board (indicated as RAP in the wiring diagrams). This signal occurs if the compressor switch deactivates during operation. AP (Table 2, contact ID4, clamps M7.7 - M7.8, normally closed)
4 104		Flow switch	This signal occurs with the opening of the contact relative to the differential flow switch or pressure switch; this alarm is not relative for the first 40" from pump start-up. The machine blocks in alarm mode when the maximum number of flow switch interventions allowed (expressed by the set_factory parameter (y): default 5) is exceeded. If the frost protection in standby mode is activated (and therefore also the pump), the state of the flow switch is also controlled. FL/PD (Table 2, contact ID2, clamps M7.3 - M7.4, normally closed)
		Water differential pressure switch
5 105	Low pressure switch		This signal intervenes when the contact relative to the low pressure switch opens (compressor intake). BP (Table 2, contact ID5, clamps M7S.1 - M7S.2)
6 106	No water inlet probe This signal occurs when the water inlet probe is disconnected
7 107	No water outlet probe This signal occurs when the water outlet probe is disconnected
8 108	Water freezing		This signal occurs when the anti-freeze threshold is reached (set_installer (6) default: 3°C) from the output water temperature. The pre-alarm state is exited with outlet water temperature temperature exceeding the set_installer (6) + set_factory (J) (default 3+1=4°C). The anti-freeze alarm is suspended (in heating mode) for a period of time equal to 3' (set_factory parameter (H)) from compressor switch on.
9 109	No pressing line probe		This signal occurs when the pressing line gas probe is absent
10	110	High pressing line gas temperature	This signal occurs when the temperature of the pressing line gas (SGP probe) exceeds the threshold envisioned by the parameter (set_factory (6), default 135°C). The pre-alarm state is exited with set_factory (7) temperature (default 135 - 10 = 125°C)
11	111	Flow pressure transducer no compressor	This signal occurs when the compressor flow transducer is absent and the machine is set as heat pump or the presence of the DCP is set
12 112	High pressure		This signal occurs when the transducer detects a flow pressure over the set-factory parameter threshold (8) (default: 40 bar). The pre-alarm state is exited with set_factory (8) - set_factory (b) pressure (default 40 - 2 = 38 bar)
13 113	No defrosting probe		This signal occurs when the defrosting probe is absent and the machine is set as heat pump
14 114		Intake pressure transducer no compressor	This signal occurs when the compressor intake transducer is absent and the machine is set as heat pump
15 115	Low pressure		This signal occurs when the compressor flow transducer indicates an intake pressure below the threshold set by the set_factory (9) parameter in cooling mode (default 4 bar), set_factory(A) ion heating mode (default 2 bar). The pre-alarm state is exited when the intake pressure exceeds the intervention set_factory(b) threshold default equal to 2 bar. The low pressure alarm is suspended in heating mode for a period of time equal to 3' (set_factory parameter (H parameter) from compressor switch on. It is permanently suspended during cycle reverse
16 - Low	performance		Every time the machine is powered, the control checks compressor behaviour once via the yield control procedure (see 8.1); this control is disabled from dip switch
17 117	Pump magnet	circuit breaker	This signal intervenes if the magnet circuit breaker switch protecting the pump is opened. MTP (table 2, contact ID3, clamps M7.5 - M7.6, normally closed). This code is displayed only if the board is used as a board spare part with SW up to version 3.6.
18 118	High pressure	partialisation	This signal occurs every time a partialisation takes place due to the threshold mentioned in paragraph 8.5 being reached. The machine blocks in alarm mode when the maximum number of partialisation interventions allowed (expressed by the set_factory (5) parameter: default 5) is exceeded. With inverter machine mode, it also indicates a partialisation due to high compression ratio.
19 119	Low pressure	partialisation	This signal occurs every time a low pressure partialisation takes place, par. 8.5. The machine blocks in alarm mode when the maximum number of partialisations allowed (expressed by the set_factory (5) parameter: default 5) is exceeded.
20 120	Pressing line temperature partialisation		This signal occurs every time a pressing line temperature partialisation takes place (par. 8.5), the machine blocks in alarm mode when the maximum number of partialisation interventions (expressed by the set_factory (5) parameter: default 5) permitted is exceeded.
21 121	Bemf error		Error in detection of the back emf. This error is returned by the inverter control board and is linked to compressor peak problems (longertek 4 code or longertek 20 code)
22 122	Internal communication error		The inverter control board has internal communication problems (longertek 5 code)
23 123		Over-current	Excess current absorption by compressor (longertek 6 code)
24	124	No load	The compressor does not absorb enough current, it may turn in idle mode (longertek 7 code)
25	125	Incorrect voltage	The inverter control board indicates incorrect bus voltage (longertek 8 code)
26	126	Error on start-up	The inverter control board indicates incorrect start-up of the PMSM motor (longertek code 9)
27	127	IPM protection error	Error on the IGBT (longertek 12 code)
28	128	EEPROM error	Eeprom error on the inverter control board (longertek 13 code)
29	129	Compressor stall Code longertek 16
30	130	No communication	The inverter control board does not respond. It may not be powered or the serial cable could be disconnected or the A and B signals reversed
31	131	PFC Module	PFC inverter module error (longertek 23 code)
32	132	Cooling fin overheating	(code APY 1)
33	133	Over current in acceleration mode	Hardware error (cod. APY 2)
34	134	Over-current at constant speed	Hardware error (cod. APY 3)

47 147		Cooling fin temperature sensor error	(code APY 16)
51 151	Anomalous condition		Protection frequency against over-current and overheating reduced. (code APY 20)
54 --	Cycle reverse valve faulty		The cycle reverse valve could be faulty or broken. (see 8.4)
55 155	Water inlet high temperature		The water inlet temperature has exceeded the set_installer (H) parameter value. Probable boiler presence on same plant. At the third intervention of the pre-alarm, the machine goes into alarm mode and blocks
--	156	Cycle reverse due to high temperature of the pressing line gas	This pre-alarm indicates the intervention of defrosting due to cycle reverse without having respected the times between cycle reverses. Cycle reverse has been triggered by the pressing line gas high temperature partialisation threshold being exceeded, set_factory (6)-set_factory (4) = default 130°. This pre-alarm does not cause compressor stop and does not have a limited number of interventions
57 157		Reading error of the DHW control board remote probe.	This pre-alarm indicates a remote probe fault or a communication problem with the DHW control board. The alarm is only active if the parameter (0)=2 or the parameter (8)=4 in the menu with password = 30
