My humidifier recently stopped working. No water is being feed through to the unit. When I place it in test mode I get an R1 error code and flashing blue lights. Please let me know what I need to do to fix my unit asap.
Thank you for contacting us regarding your model 600M humidifier. The R1 that you see on the screen after the test mode simply means the control is a revision one control. This revision indicator has no effect on the operation of the control or the humidifier. The blinking blue lights with the R1 simply tells us that the test mode is over and the control knob is still in the test position. If left in test, the control will not turn the humidifier on at all.
If water flows through the unit while in test, then it may not be running because of the current level of relative humidity. Typically when the solenoid operates in test, the system is working fine. If the control is reading a relative humidity level at or above 45%, the unit will not operate outside of test. Also, there is an accuracy differential of +/- 5%. For example, it is possible that the control displays 40% but still does not operate on the highest setting.
Additionally, if you are using the outdoor temperature sensor for automatic operation, the outdoor temperature may be the cause for the humidifier to not run. If the outdoor temperature is at or above 55 degrees the control will not turn on the humidifier.
