5 Electrical Connections

5.1 CONNECTING THE WIRING CENTRE

The wiring centre is to be powered with 230V AC/50 Hz voltage. The electrical installation should be:

Fused at 3A and earthed,

Cable size to be 0.75mm2 – 1mm2.

In accordance with current regulations,

must be protected with a residual current protection

device (RCD) with a rating In=30mA.

! WARNING !
All electrical scheme components should be connected only by qualified persons in accordance with applicable regulations. Follow safety precautions to prevent electrocution.
! WARNING !
After the wiring centre is turned off dangerous voltage on terminals may still be present. Before removing cover, disconnect the main power supply and use a Multimeter to check for voltage on terminals and leads.
For safety reasons, the wiring centre must be connected to a fused 230V AC power supply, with the sequence of connecting the live (L) and neutral (N) wires. Make sure that the L and N conductors are not crossed within the building’s electrical system, e.g., in an electrical socket or junction box.
5.1.1 ELECTRICAL CONNECTIONS All wiring connections should be made to the corresponding terminals on the pluggable terminal blocks supplied in the accessory and fixing pack. 1. Remove the terminal cover from the wiring centre housing.
Refer to Figure 5-3
! NOTE !
Isolate any incoming voltages on connections before removing the wiring centre cover beginning to connect to the wiring centre.

Figure 5-2: Wiring centre terminals cover
3. Connect the earth wire to the earth terminal strip inside the wiring centre housing.
4. Arrange the wires to prevent damaging the insulation by cutting it with cover edges or screws securing the cover.
5. Secure wire with cable clamp to prevent loosening from potential mechanical stress.
! WARNING !
The maximum length of the exposed wires extending from the outer cable sheath should not exceed 50mm. Connection cables should not be on contact with surfaces that exceed nominal operating temperature of 50°C.
! CAUTION !
All cable clamps must be fitted even if not all clamps are needed to maintain IP20.
! NOTE !
The wiring centre cover should always be in place before connecting the electrical supply.
5.2 COMPONENT CONNECTIONS
Electrical components of the planned system are to be connected to the wiring centre of the Grant Aerona smart controller. Refer to Section 5.4 for wiring centre layout. With the adjustable circuits, mixing needs a water temperature sensor connected to monitor the mixed water entering the circuit to adjust accoridngly. Table 5-1 displays the relation between the individual heating circuit and its associated component terminals.

Section 6: System Configuration with Touchscreen

Page 21

6.3.2 HEATING CURVE ADJUSTMENT The heating curve is adjustable and should be reviewed to ensure both comfort and economy.
The heating curve is set as part of the initial system configuration when configuring ‘Weather’ control but can be edited after the system configuration has been completed. Refer to Section 7.3.1.3 to access the heating curve setting adjustment, Figure 6-7 and Appendix F.7 for a QR code link to a how to video on adjusting the circuit heating curve.
Guidelines for adjusting a heating curve
· If the outdoor temperature drops, and the room temperature increases, the selected heating curve value is too high.
· If the outdoor temperature drops, and the room temperature drops as well, the selected heating curve value is too low.
· If during frosty weather the room temperature is comfortable, but when it gets warmer the room is too cold, it is recommended to increase the Heating curve shift and to select a lower heating curve.
· If during frosty weather the room temperature is too cold, and when it gets warmer the room is too hot, it is recommended to decrease the Heating curve shift and to select a higher heating curve.
Poorly insulated buildings or the use of traditional steel radiators require setting higher heating curves. Well insulated buildings and/or low temperature heat emitters e.g. Undefloor heating, heating curves will have a lower value.
6.4 CIRCUIT CONTROL SETTINGS
6.4.1 FIXED CIRCUIT CONTROL
(Not weather compensated) If the heat emitter size is known, set the required water temperature in the circuit using parameter ‘Fixed preset water temperature’, e.g., at a value of 50 °C. The value should allow the room to reach the required temperature.
After connecting the room thermostat, it is necessary to set a value of decrease in the Decreasing fixed water temperature parameter, e.g., to 3 °C. This value should be selected by trial and error. Upon activation of the room thermostat, the target circuit temperature will be decreased, which, if proper decrease value is selected will stop rise of temperature in the heated room.
6.4.2 WEATHER COMPENSATED CIRCUITS
(Not Fixed) The Outdoor weather sensor must be installed and configured to be able to use weather control. Using Heating curve shift, set target room temperature following the formula: Preset room temperature = 20°C + heating curve shift.
In this setup, it is possible to connect a room thermostat which will equalise the inaccuracy of set heating curve, if the selected heating curve value is too high. In such case, it is necessary to set the value of parameter Decreasing fixed water temperature, e.g., to 2 °C.
When the target temperature of the room thermostat is achieved, the Heat pump target flow temperature will be decreased, when pump blockade for that circuit is off. If pump blockade is on, the circuit pump/valve will close (if installed).

6.5 COMMON SETTINGS
After the system has been configured, check and if needed amend some common settings within the Heat pump parameters menu via the touchscreen display (Refer to Table 6-2). To access the Heat pump parameters menu: 1. Tap the Settings menu and select ‘Service settings’ and enter
the password: 1234. Refer to Table 7-1 and Section 9 for full Heat pump parameters listing.

7.2 SMART CONTROLLER OPERATION
7.2.1 MAIN HEAT SOURCE The Grant Aerona Smart controller manages the operation of the heat pump by activating or deactivating it according to demand for DHW or the space heating circuits.

20,5°C

7.2.2 HEAT CIRCUITS The Grant Aerona Smart controller can manage the operation of one non-adjustable and up to two adjustable heat circuits. Water temperature in circuits can set as a fixed flow temperature or by weather, i.e., water temperature in the circuit is calculated in accordance with a temperature from the external temperature sensor. Despite varying outdoor temperature, a room temperature in heated rooms is kept on a set level. · Dependent circuits A thermostat assigned for many circuits.
For example, temperature readings on a installed panel affect operation of both radiator and underfloor circuits. Commonly one Thermostat in a central location.
· Independent circuit Connecting thermostats to measure room temperature independently and affecting assigned circuits. It is the way to obtain independency of the circuits, e.g., in case when one part of the building is used for the whole year and the second part is used periodically, e.g., for rent.
If multiple circuits are being controlled you can navigate between them with a swipe of the screen either to the left or the right.
7.2.3 DOMESTIC HOT WATER The Smart Controller manages the operation of the Heat Pump and heating of a DHW cylinder up to a user set temperature. DHW operation can be programmed in time intervals with a minimum operation for disinfection mandatory. While the Smart Controller can also control a DHW secondary circulating pump, their use is not recommended to minimise wasted energy and running costs.

7.3.2.3 DHW ADDITIONAL SETTINGS DHW additional settings provides a sub menu for the DHW cylinder hysteresis parameters & Legionella protection (If additional heater is configured – Refer to Section 7.4). DHW Hysteresis is the amount of temperature drop from the user set temperature in the cylinder before the system will demand more heat in a scheduled ON time period. If the hystersis setting is too low this can cause potential cycling of the heat demand in an scheduled ON period. Too high can cause the cylinder to not reach desired temperature and higher energy useage.

7.4 LEGIONELLA PROTECTION
The Grant Aerona Smart controller has the function to provide protection against legionella by executing a scheduled temperature increase. This is executed on a weekly basis from within the Grant Aerona Smart controller settings.
For protection against legionella the DHW cylinder needs to be periodically raised to a minimum of 60°C to ensure it is sterilised of any present legionella bacteria.
Care must be given to vulnerable people who may be exposed to potentially life-threatening legionella. This group of people include the elderly, pregnant women, young children and those with breathing difficulties. Where legionella disinfection is required more frequently than once a week, this must be provided by other means.
It is important that this decision is based on the welfare of the occupants and not on energy saving measures.

7.5 TIME SCHEDULES
The Grant Aerona Smart Controller allows for programmable time schedules for the Heating Circuit(s), DHW and the Heat pump itself.
In the situation when the consumer is not at home or at night, the controller can decrease the amount of supplied heat which affects electric consumption.
Time schedules can be set separately for each day of the week or copied across multiple days. If the space is unoccupied Monday to Friday for the same time periods the user could set the hours for Monday and then apply to multiple days.

Schedule

12:00 Mon.14.11.2022 Monday

! WARNING !

If the hot water stored in the cylinder has not been used

for a prolonged period of time (e.g., a few days) and has

not been stored at 60°C, then it is important that the

temperature is raised to at least 60°C for a period of one

hour before using the hot water.

Appendix A Wired Thermostat

A.1 GENERAL
The Grant Wired thermostat is designed to provide individual circuit control via the Grant Aerona Smart Controller.
The thermostat is installed in a suitable location to monitor the circuit, e.g., Ground floor hallway, and is designed to maintain a target temperature.
The thermostat on the backlit LCD display shows information about the circuit temperature value, selected operating mode, current time with simultaneous clock synchronization with the main controller.
A.2 INSTALLATION
The thermostat is intended for installation only in a dry, habitable location and should be mounted to the wall. After choosing the place of installation, make sure that:
· The selected location is free of excessive humidity and the ambient temperature of the thermostat should be within the range of 0 to 40oC,
· The chosen location should ensure free air circulation and should be located away from heat-emitting sources, e.g., electronic equipment, fireplace, heater and direct sunlight.
· The thermostat should be mounted at a height enabling convenient operation, typically 1.5m above the floor. (Refer to Figure 3-1)
The thermostat should be screwed to the wall with mounting screws. Access to the screw holes is obtained by opening and removing the back cover of the thermostat. A flat screwdriver can be used to open the cover.

Before reattaching the cover, lead the wire connecting the thermostat with the wiring centre through the hole. The cable must be recessed into the wall. The cable can not be routed together with the electrical cables of the building. The cable should not run in the vicinity of devices emitting strong electromagnetic fields. Then attach the thermostat to the mounting frame using the clips. The VCC, GND, D+, D- terminals of the thermostat should be connected to the transmission socket of the main controller. Refer to Figure A-3.

A.4 PAIRING
The wired thermostat should be connected as part of the Smart Controller configuration creator for the circuit that the thermostat will measure. To pair again you can follow this within the individual circuit settings to re-pair to the Grant Aerona Smart controller.
· Access the circuit you wish to pair with a wired thermostat panel from the Circuit settings within the System settings menu (Refer to Section 8) and select the Thermostat option from the menu and confirm you wish to overwrite if a thermostat is already present on the circuit.
· The pairing wizard will begin and will instruct you to set put the desired wired thermostat into pairing mode.
· Follow the on-screen prompts. Hold the up and down buttons simultaneously for 2 seconds. The screen will change to display you have entered the user menu where you then select parameter 03 in the user menu of the thermostat. “PAr” will be displayed on the screen. After accepting with button, the pairing will start (the word “PAr” begins to flash).
· Confirmation of the pairing will be confirmed by the message “END” and “Succ” on the thermostat.
· After pairing a room thermostat holding the tick down will return you first to the previous menu and then the back to the main screen in 2 second intervals.
A.5 CHANGING SETPOINT TEMPERATURE
Tapping the up or down arrows will prompt the thermostat into the check/editing of target temperature causing the current target saved temperature to flash. The first tap of the arrow will trigger the edit temperature function but will not change the value. Tapping the arrow again will then change the value either up or down. Tapping the tick will confirm, save and exit.
Not confirming a new target with 5 seconds of inactivity will cause the thermostat to exit the editing mode without changing the target temperature.
! NOTE !
Holding the up or down arrows for more than 2 seconds will cause a fast change to the parameter.

A.6 HOTEL MODE
Hotel mode can disable the wired thermostats ability to change the Smart Controller parameters and schedules. We recommend this be activated to avoid conflicting programmed settings between the wired thermostat and the Grant Aerona Smart controller.
1. To access the service menu press and hold the down arrow and the confirmation tick capacitive buttons for 2 seconds. After which you will need to enter the number sequence 1410 and confirm with the tick.
2. To enter the password you will need to cycle each of the 4 digits with the up or down arrow and confirm that digit with the tick. On the confirmation of the fourth digit you will continue to the service menu.
3. Navigate to parameter 2 and select Hotel mode with the tick. Default setting for hotel mode is off and the arrows will cycle through options. Ensure On is visible and confirm.
4. Holding the tick for 2 seconds will save and exit the menu back to the main screen.

A.7 ERROR CODES
The Grant Aerona Smart controller communicates alerts to the thermostat panels when present in the system. Refer to Table A-2 for determining the fault.

Appendix B Wireless Thermostat and Receiver

B.1 GENERAL
The Grant Wireless receiver & thermostat are designed to provide wireless circuit control via the Grant Aerona Smart controller.
The thermostat should be installed in a suitable location to monitor the circuit, e.g., First floor hallway, and is designed to maintain a target temperature. by sending a radio signal to the module connected to the wireless receiver.
The thermostat on the backlit LCD display shows information about thecircuit temperature value, selected operating mode, current time with simultaneous clock synchronization with the touchscreen display.

P LED D- D+

GND +12V

B.2 INSTALLING WIRELESS RECEIVER
The wireless receiver should be mounted on a wall near the installation location of the wiring centre. If the radio connection is poor, try placing the wireless receiver in other places. Moving the wireless receiver even by a few centimetres can affect the quality of the connection.
! NOTE !
Placing a wireless receiver in a metal casing, e.g. a mounting box, a metal boiler casing, etc. will block the radio signal and thus interfere with the operation.
The radio module should be screwed to the wall with mounting screws. Access to holes for screws is obtained after unscrewing the cover of this module. Refer to Figure B.1.

4 x 0.5mm2 wire max length 30m
Figure B-2: Wireless receiver wiring
! NOTE !
Ensure the correct polarity of the connection of the D+, D- signals and the GND, +12V power supply between the thermostat and the wiring centre. Incorrect connection may lead to damage to the main controller or errors in its operation.
The maximum cable length depends on the cross-section of the wires. For a 0.5 mm² wire, it should not exceed 30m. The crossSection should not, however be less than 0.5 mm².

Figure B-1: Wireless receiver wall fixings
Terminals D +, D-, GND, 12VDC of the Wireless receiver should be connected to the G1 socket of the wiring centre.
