Page 11: Section 1 Installation
All units must be installed in accordance with the current National Electrical Code. Best Energy Saving Technology Ltd, or their agents do not assume any liability, expressed or implied, for any consequences resulting from inappropriate, negligent or incorrect installation, application, use or adjustment of this device.
Page 12 Mounting the ACES2 Opening the ACES2 There are 4 screws on the back of the ACES2 Enclosure, once removed the front lid will come off and you can see the boards inside. Please note you will need to screw the lid down again before final mounting to the wall.
Page 13 Location ACES2 Location You will need to consider the best location of the ACES2 unit to get all the connectivity options. The ACES2 unit will need: Internet access via rj45 An earthing point for the shielded cable Wall socket (100-240V) for power point 2 wire cable for each evaporator temperature sensor or thermostat to take control.
Page 14: Cables And Wiring
Cables and Wiring Power Cable The unit comes with a UK plug end and a 110-240v supply, (The Smart Switch requires 8 to 55V DC supply) to plug into a wall socket, we recommend you use an existing wall socket point or create one from the Distribution board with a switch.
Page 15 Temperature Probe Wiring Use the RJ12/RJ11 cable provided with your ACES2 and connect to the mainboard and the splitter like shown below: Below are the Splitter wiring details: ACES 2019 – User Manual Page 15 of 45...
Page 16 If you decide not to use the splitter and you have cut the RJ12/RJ11 cable for direct connection, then pin2 (Vcc), pin4 (Data) and pin5 (ground). The temperature sensor will come with 3 wires: Red = Vcc (5v) Black = Ground Yellow = Data (1 Wire) The sensor Data wire should be routed through the relay0 NC (normally closed) and C...
Page 17 Aircon Signal cables Please use 26AWG 2 wire (1 pair) or larger, you will need 1 cable per aircon system and all cables must lead back to the ACES2 unit. Your first step is to open the Aircon Evaporators and identify the air temperature sensors. Please note we want the room air sensor, not the coil temperature sensor.
Page 18 Note: Remember a cold signal is used to turn the system off (0) and hot signal is used to bring cooling on (1). Now for terminating the signal cables to the ACES2 unit, pass the up to 4 signal cables (up to 4 Aircon control) through the glands and wire to the black terminals of the relay outputs.
Page 19 Login using the default IP 192.168.1.100 and user admin, password admin. You can login by typing the IP into the browser like with Eniscope (but do not need /admin). You will find it best to connect to the ACES2 unit with a direct cat5 cable from your laptop (bypass any router for now).
Page 20 Set the Time Click the ‘time’ menu option and select the NTP option (or set the time manually) and save. Also click the ‘set time in RTC’ to save to controller. Also you can select your timezone. To check the operation is successful go to the ‘status’ screen and check the date and time displayed up top.
Page 21 Set the Potentiometers and test Now all the wiring is in place it is time to set the potentiometers to the values you recorded from testing the AC sensors, do this using a multimeter set to resistance and set the pots shown below. Note that you should disconnect 1 wire while setting the pots and manually change the state of the relay to set the 2 values, once set reconnect the wire.
Page 22 Check your Relays and temperature sensor readings Manual Switching checks: Stage 1: Select the Status menu tab and check that turning on out1, 2, 3, 4 turns on the corresponding relays (turn off when finished) in the software. Also check that when you manually turn on an output that the relay board LED comes on for that output (each relay has its own LED).
Page 23 Temperature sensor checks: Also check you can see your temperature sensor reading under the DS1 to DS8 selection on the status screen. To move the sensor reading to DS1 or assign a missing sensor go to the 1 wire option. From the 1 wire option menu click the Read ID (it should produce a unique MAC number) and then save to position 1-6.
Page 24 F. Setting the Programmable Logic Understanding the Events Screen On the Events screen we can see the programmable logic for setting our relay outputs based on the temperature or digital/analogue inputs thresholds. 1. Select the temperature sensor(s) or digital/analogue input you wish to monitor. 2.
Page 25 Finding your temperature threshold Before setting the events you need to work out the temperature difference between your sensor position (usually in the roof which warmer than room below) and the temperature of the room at chest height. Use a digital thermometer like shown below and measure in the centre of the room around waist-chest height.
Page 26 Setting the Events For 2 and 3 Aircon control use the below setup. For 4 Aircon system contact BEST to discuss the best arrangement. 2 Aircons 3 Aircons Events control Test Last test is to let the room heat up to 26 degrees then turn on the events control (tick the boxes) and remember to let only the number of aircons you expect to be on at any one time to be active (i.e.
Page 27 Select the ‘MQTT Client’ in the ACES2 to set up communications and then in a browser type: aces2.eniscope.com Login to your account, if you don’t have an account yet then please contact BEST for one. Now enter a name for the ACES2 and choose the LK3 option. Click add device.
Page 28 If you have trouble with the quick configuration you can also set the MQTT connection manually, to do this go back to Devices menu Now click on the blue banner titled ‘to add a new device’ and follow the instructions. ACES 2019 –...

Page 30: Device Menu
The Remote options Device Menu Under the Device menu selection, you can see your ACES2 listed and besides them is a chart and table option. Temperature Chart Selecting the chart option, you can see data for the last month for the ACES2 temperature sensor, if setup correctly you should see a reasonable controlled tight formation like the above example.
Page 31 Temperature Table Here you can analyse your ACES2 system more closely than the chart and compare the various output states against the temperature reading to check if the unit is triggering on the correct logic. Also on the top of the Table screen you have the ability to download the data in a CSV format.
Page 32: Control Panel Menu
Control Panel menu Services This section is where you set the address of the items we want to communicate with, in this case we use the smtp service to publish a message to an email and the mqttpub service to point to the CMD (command console) of a particular ACES2 unit we wish to control.
Page 33 Tasks The task section is essentially where we can schedule compressors on or off during the day. For instance for a 24hour store with 2 AC, we can schedule one AC for 12hours and the other for the next 12hour. MQTT Client The MQTT client can be used to send instant manual commands remotely, firstly check for the green connected symbol in top right corner.
Page 34 Setting up the Standard 1 Sensor Remote Logic As well as the onboard programmable logic option, you can activate your outputs/relays remotely using the config panel such as remote scheduling of AC on and off to working hours of site. We will now list the recommended logic controls to use on your ACES2.
Page 35 Reactions Setup Email Alerts The email alert system will send a message every 5 minutes when outside the trigger range, so we know when our site is getting to hot or cold. In this example above, it would trigger the alert if the temperature goes above 30 degrees or below 20 degrees based on (filter) settings.
Page 36 Auto Reconnect of ACES2 Sensors In rare instances, the digital temperature sensor could state 85degrees, which is a misread error and the unit should recover from. But if it prints -60, then the sensor has failed and needs to be restarted via out0 switching on and off (which from our installation process is the data wire) to do a hard reboot.
Page 37 Auto2 Instruction The second instruction above, basically monitors the state of out0 on the ACES2 system (Topic), if it is 1 (Filter (value)), it will reset it back to 0 (Format) by sending the command to the ACES2 (Services). Take note on this setup we do not use a delay time (suppression) so can act as soon as updated from ACES2 unit.
Page 38 Tasks Setup Tasks section, can be used to schedule an output on and off, such as to have more unit running during a midday heat and a single unit at night. Or if you have a 24hour site and 2 aircon you could schedule 1 to run during the day and the other at night, giving them a off cycle and energy saving.
Page 39 (O ptional) Remote Temperature Adjustments It is possible to remotely adjust the temperature threshold for switching on the compressors up from the value set via the onboard events on the ACES2. But we cannot reduce the value down (for this you will need a site visit to edit the events temperature threshold or port forwarding setup).
Page 40 Temp_Adjust1 allows the compressor to come on at the new desired temperature (Filter (value)) in this example it is 25.5 degrees which is 1 degree increase from the events setting. It then allows compressors on (format) by sending to the ACES2 unit out5=0 (Services). Temp_Adjust2 is used to turn the compressors off when it drops below 25 degrees, by sending out5=1 (Format) to theACES2 (Services).
Page 41 Setting up the Remote Logic for Multiple Sensors (Optional) Please see the below Events recommendations if using 2 sensors setup. 2 Aircon 3 Aircon Please ensure DS1 is positioned near to AC1 (not directly in airflow) and 2 meters away from the door or window.
Page 42 Example In this example we will have 3 AC system with 2 sensors, idea is only 2 AC will work during the day (AC1&AC3) and 1 at night for a 24hour store (AC2). Logic: Basically, DS1 will control AC1 exclusive when operating during the day, AC1 is near the door/window and will work the most.
Page 43 Making Edits in ACES2.Eniscope.com When you want to add new commands to Reactions, Tasks or MQTT Client you need to login via incognito window. This ensure no one can accidentally change setting while viewing. All major browsers have a incognito mode and above is an example for google chrome. If the mode is working correctly you will see the MQTT On in the bottom left corner.
Page 44: Section 3 Troubleshooting
SECTION 3 TROUBLESHOOTING Factory Reset Pressing the reset button for about 0.5 seconds to change state relays, and hold for longer (up to five seconds) will change all settings (both network and configuration) on the factory reset. Confirmation of the settings is fast switching on and off the relay. ACES 2019 –...
