Many issues caused by the controller can be resolved with a hard factory reset of the controller. Listed below are the instructions to do a complete 'hard' factory reset of the controller.
Please follow these steps below:
1. Power off the controller completely by holding the "Rst" aka Reset button until controller powers off.
2. Hold in the “SET” and “UP ARROW” button together immediately after powering back on the controller (press reset "Rst" once to power back on). Do not let go of the "SET" and "UP ARROW" buttons.
3. Keep holding those 2 buttons for approximately 10 seconds after you switch on the power until the unit fully resets. You should see the following: - - - C on the face of the controller if the hard reset is successful. (If you do not see this repeat steps 1-3 until the hard factory reset is successful).
The controller will be completely reprogrammed and you will need to do a complete reprogramming of the internal settings at that point. If this does not fix the issue the controller will need to be replaced. Please keep in mind that after your reset the controller you will need to change the settings back to the needed settings for your incubator.
Please see the product page under the 'Manuals & Instructions' tab for a pdf titled Multi-Display Temperature Controller Instructions for resetting your controller back to the initial settings when the unit arrived.
