Yellow light still blinking…I have a model 600 installed by a licensed contractor a year ago and it has a control unit with a digital readout but no manual switch nor a test -reset setting on the dial. It has three lights to the right of the readout. The yellow one is lit indicating to change the A-35 pad which I did. How do I reset this type of control unit?
Thank you for contacting us regarding your model 600. To reset the change water panel light, put the control in the test/reset position while the furnace is on and the HVAC fan is running. After the control runs in the test/reset position for 1 minute, put the control knob back to the previous setting. This will reset the internal timer for the light and turn it off.
The words test/reset can be a little hard to read but they are located past the setting of 7. The letters are the same color as the plastic but are raised and you can feel them with your fingertip.
Please view the attached owners manual for the model 600. This procedure is explained on page 3
