From what I observed, if the thermostat is disconnected while the switch is in OFF position, the display will show "cold". Pushing the diagnostic button clears the fault.It may do if you turn it off first. If you do it while the controller is on, it throws an error light, at least mine did. I did not try to turn it on without the resistor in the circuit.
There is no fault condition if the thermistor was disconnected prior to powering on the system. I do take precautionary measures when working with electronics and I did not try disconnecting the thermistor whilst the cell is chlorinating! I can only assume the drastic changed in temp will show cold. And not sure at what point it will resume chlorinating if indeed it was interrupted.
