EXPLOITATION CONDITIONS
Do not expose the control panel to direct weather conditions (rain, sunlight) and vibrations higher than typical during wheeled transport. Do not use in conditions of condensation and protect from water.

CLEANING AND MAINTENANCE PROCEDURES
The outer surface and maintenance of the control panel screen.

• The device should be cleaned with a soft, dry cloth.
• It is not allowed to clean the device with a flammable agent or substance (i.e. benzene or any kind of solvents) or a wet cloth. Such treatment can lead to the malfunction of the device.
• It is not allowed to scratch the screen with nails or other sharp objects. It can lead to scratches or damage to the device.
• It is not allowed to clean the device by spraying water on it. If the water gets inside the device it can cause a fire or lead to electrocution or damage the device.

INSTALLATION

The control is intended to be installed on the wall or placed on a flat surface, only in a dry room. The panel cannot be used underwater under vapour condensation conditions and must be protected against water. Room thermostat must be installed on the height allowing its convenient use, typically 1.5 m over the floor.

• To reduce the interference of temperature measurement by the control panel, avoid sunny places with poor air circulation, close to the heating devices and place directly at doors and windows (typically at least 200 mm from the door edge). Control panel installation should be done according to the instructions below.
• Disconnect the installation frame (1) from the back of room thermostat housing (2). The frame is attached to the panel housing with latches.
• Use a flat screwdriver to detach the frame.
• Using a sharp tool cut out holes in four places of the cover (3) for the screw terminals.
• Connect the wires of a transmission cable, connecting the control panel with the heat pump, to the screw terminal (4) as described on the plate
• The cable connecting the control panel with the heat pump can be cessed in the wall or can run over its surface – in such case the cable should be additionally placed in the cable channel (6) of the installation frame. The cable connecting the panel with the heat pump cannot be conducted along with the cables of the building mains. The cable should not be routed near devices emitting strong electromagnetic fields.
• Drill holes in the wall and using screws (max. Ø 3 mm) fix the installation frame in the selected place on the wall, maintaining its proper position (UP). The spacing of holes can be determined by placing the frame on the wall. Next, fix the panel to the installation frame using latches.
• To place the control panel on a flat surface use a dedicated stand.

WIRING
You need two cables for the connection between the e-LITE remote control panel and the water chiller/heat pump unit:

• 5X1mm2 twisted and shielded cable for Modbus communication D+/D-, PE, and 12Vdc power supply, which is included in the box.
• NB: The shield of the cable must be connected to PE in both of its ends.

SOFTWARE UPDATE
The software update is possible using only the microSD HC memory card (max. 32 GB, FAT32 files format) inserted into a slot in the control panel housing. To replace the software, insert the memory card into the control panel slot – the software will be replaced automatically after inserting the card. The card should contain the new software in *.pfc format (the new software should be copied directly to the memory card, not to a subdirectory).

DISPLAY ICONS
The following is the list of main icons with relative meaning.

9| Outlet water temperature
10| Inlet water temperature
11| Current heat-pump status

The possible status of the hat pump is the following:

• Pressing the symbol, the heat pump work modes are displayed:
• Tapping symbol, the setpoint settings are displayed:
• Tapping symbol, the season and the scheduling menu are displayed:
• By tapping on the season switches, the selected season is activated for the heat pump and the thermostat function.
• Pressing Winter or Summer installation schedules, the scheduling screen is showed:
• The strip represents the day, which is divided into 48 parts. Each part is 30 minutes. It is possible to change the day, with the > and < arrows.
• The upper part represents the plant water outlet enabling, and the lower part represents the Domestic Hot Water enabling.
• The azure, lower strips represent cooling mode, Eco setpoint.
• The blue, higher strips represent the cooling mode and comfort setpoint.
• The orange, lower strips represent heating mode and Eco setpoint.
• The red, higher strips represent the heating mode and comfort setpoint.
• The grey strips represent disabled mode.
• The “copy symbol “, allows us to select the days of the week, when we want to have the same program as the shower day.
• It’s possible to scroll in the left and right position, modifying every single area, by enabling the next symbols (by pressing the respective symbols):

DHW SCREEN
In the centre of the screen, the temperature measured by the DHW probe is shown. On the right, below, the set-point temperature is shown. By tapping on this screen, the DHW set-point edit screen is shown.

NOTE

• When the DHW is disabled, the next message is shown: “Domestic
• Hot Water support turned OFF. Press here to go to settings.”.
• By tapping, the next screen will be displayed:

By pressing the gear symbol, it is possible to set the anti-legionella scheduling
The DHW support switch enables/disables the DHW function. The time in which the request for the anti-legionella cycle is sent is one hour. During this period, the DHW temperature must be higher than
r27 [°C] (DHW setpoint during anti-legionella cycle), for r26 [minutes] (anti- legionella cycle duration). The positive or negative results of the anti- legionella cycle, are stored in the Alarm History menu.

NOTE
See the heat pump MCO, to configure and enable all the resources requested by DHW.

NOTE 2
For the anti-legionella support, DHW support and all the requested resources must be enabled. See the heat pump MCO, to configure and enable all the resources requested by anti-legionella.

THERMOSTAT SCREEN

The thermostat function, uses the e-LITE internal probe, to measure the room temperature. By activating this function, the internal probe will be used to switch on or off the heat pump. The thermostat call will be sent to the heat pump if: The unit is in cooling or heating. The internal probe temperature hasn’t reached the setpoint yet For details of the behaviour of the machine in the absence of the room call, refer to the machine specifications.

NOTE
See the heat pump MCO, to set the types of regulations when the ambient probe is satisfied. In the centre of the screen, the temperature measured by the internal probe is shown. On the right, below, the actual set-point temperature is shown.

THERMOSTAT SETPOINT SETTINGS
By tapping on the measured temperature, the thermostat set-point edit screen is shown: By tapping on the gear symbol, the Thermostat settings are shown:

Depending on heat pump parameters (see heat pump MCO)

Winter economy preset| Economy setpoint temperature for Winter mode.

Summer economy preset| Economy setpoint temperature for Summer mode.

Thermostat histeresis

| After the air setpoint is reached, the thermostat call will be sent to the heat pump again, when the air temperature will:

in heating mode: decrease lower than “air setpoint – Thermostat hys- teresys”

in cooling mode: encrease higher than “air setpoint + Thermostat hys-

teresys”
