Two flow meter plugs for sensors to connect are located only on SensorHUB extension board — there is no way to connect a flow meter directly to bigGN. Te use of both sensors at once can be claimed using two WC loops. For sensor setup there is a special section in control software:
For flow data to display correctly sensor polling value must be set. Here you can also rename the sensors and set the critical values: limiting values when reached the device sends alarm signal by all means possible, other limits are used by controller to turn-off the PC when reached.
The same settings are displayed in the flow meter tab:
Emergency PC shutdown feature can also be activated in the additional feature window of the flow meter tab:
Here you can also set flow meter displayed measurement units. Average data is displayed for the time period selected in the drop-down menu.
As I said earlier, the device is capable of temperature, fan and flow rate control. If critical values are reached the device can send alarm signals by LED blinking (see the manual for Post Codes) or/and sound signal or bigGN can turn-off the PC. For safety functions to operate properly select one of them in the appropriate tab:
System failure log history can help you determine the date of the crash but can’t display the device that is guilty of it — it is up to you to find out.
I triggered the emergency situation intentionally. If pump or a fan stopped working the device made heartrending sound signal via on-board buzzer, its LEDs began blinking, meanwhile Navigator used PC-audio system to send emergency signals — you can’t miss such an alert.
PC power shut down is only available if a special cord between motherboard power button input and appropriate SensorHUB output is applied. First the device locks the contacts for one second which means PC power shut-down using software means. If this is not enough to shut down the PC then contacts are locked for 4 seconds thereby initializing immediate ATX-compatible PSU power cut-off (if motherboard manufacturer doesn’t use that 4-second PC power button pressing for something else). The time specified for computer shut-down can (and should!) be set in the appropriate window:
The difference in PC shutting down using Aquaero USB 4.0, while the last one has a special plug inserted in power connector, is that four second before the actual Power Supply shut down. There can be a lot of argues on the power shut down issue of these two controllers, who is better, but use of Aquaero USB 4.0 and T-Balancer bigNG showed the there are no significant differences — in Aquaero settings the time before the actual Power Supply shutdown is set to eight seconds by default. Usually it stays that way. The only advantage Aquaero has is the feature to control reservoir’s heat carrier level using additional sensor “Tubemeter” which can help in leakage detection.
Unlike the Aquaero USB 4.0, T-Balancer can handle light control by itself. The number of lamps that can be connected is limited to the fan channel amount. Four channels are not enough to have the control over the fans and lamps at the same time. But if you try hard you can excuse one control channel from fans thus you’ll have one channel for lamps. It is important for the device to know what channel has lamps connected. This should be done in the appropriate menu. You can also choose one of the light effect presets in the drop-down list:
The next window is dedicated to create your own light effects:
-balancer can change the lights smoothly, but can’t set light brightness in reference to temperatures in control points.
