Temperature Alarm (cont'd)
• To access the TEMPERATURE ALARM setup, when the controller is powered OFF
(and connected to the fan), press and hold the UP arrow button for 3 seconds.
Press the UP or DOWN arrows to select the temperature in which you would like
the alarm to be triggered. Once you've selected the TEMPERATURE ALARM trigger
level, press the POWER button to save it and power ON the controller.
• Once the controller is powered ON, activate the TEMPERATURE ALARM feature by
pressing and holding the MODE and the DOWN arrow buttons simultaneously until
the BELL icon illuminates on the controller's screen.
• To deactivate the TEMPERATURE ALARM feature, press and hold the MODE and
the DOWN arrow buttons simultaneously until the BELL icon disappears from the

Fan Failure Detection and Error Messages
• EC fans send frequent tachometer signals to the controller. These signals are used
to detect fan failures and alert the user by beeping and displaying error
notifications
• To use this feature, please make sure to connect your fans to consecutive OUT
ports on the controller. For instance, if you run 1 fan only then connect it to OUT1
port. If you run 2 fans on the same controller, then connect them to OUT1 and
OUT2 ports. Similarly, if you run 3 fans on the same controller, then connect them
to OUT1, OUT2 and OUT3 ports. If one of the OUT ports won't have a working fan
connected to it, but the alerts for that port are activated, it will result in false error
alerts. Only activate these alerts for the number of OUT ports currently in use.
• To activate the fan failure detection and error alerts features, when the controller is
powered OFF (and connected to the fan), press and hold the DOWN arrow button
for 3 seconds. Using the UP and DOWN arrows, select a number from 0 to 4 to
match the amount of fans currently connected to controller's OUT ports.
• 0-This mode indicates that fan failure detection is disabled for all ports.
• 1-This mode indicates that fan failure detection is enabled on port OUT1.
• 2-This mode indicates that fan failure detection is enabled on ports OUT1 and 2.
• 3-This mode indicates that fan failure detection is enabled on ports OUT1,2 and 3.
• 4-This mode indicates that fan failure detection is enabled on ports OUT1,2,3, and 4
• If your controller is connected to 4 EC fans and the fan connected to OUT1 port
becomes disabled, the controller will beep and display error message "E1"
indicating the problem is on port OUT1. Similarly, "E2" will indicate failure of the fan
on port OUT2, "E3" will indicate failure of the fan on port OUT3 and "E4" will
indicate failure of the fan on port OUT4. If multiple fans will fail at the same time,
multiple error messages will be displayed in sequence.
• Error message, Er', indicates a connection problem with the thermal probe. The
smart controller cannot operate without a working thermal probe.
