0536 thermostat Need Manuel

With many Aprilaire thermostats, the flashing 11 indicates that there is a broken wire between the thermostat and the HVAC system. You should turn off the power to the HVAC system. Then take the thermostat off the faceplate. Check for any damaged wires. If there is a break near the thermostat, take the undamaged section of wire and secure it in the correct spot. See https://www.manualslib.com/manual/8847/Aprilaire-8346.html for the installation directions.

You could also try installing a new thermostat. Then make sure that all of the wires are properly connected to the terminals. You may need to check the wires at the HVAC control board or in your wall. You may want a professional to check the system for either of these steps.

I hope this helps.

Yes it has 3 AAA batteries.
Pull it straight off the wall. Look at the back of the thermostat and replace the three batteries.

Please see previous reply at 5:40 ET- 6/24/11

did you figure out the filter? there is a filter there when you take it apart but it doesn't say anything in the manuel about changing a filter. let me know if you figured it out. thanks

I need a little more info to help you. What do you mean by "how to adjust the thermostat, for kenmore humidifier". Do you need to know what the relationship is to the setting and moisture in the air? Let me know.

It would appear to me that you have lost the 24 volt power supply to the thermostat. In referencing the manuals for this thermostat, available @ www.honeywell.com, I've found that when the thermostat is not connected to the wall plate (plate mounted on the wall, that the thermostat either snaps or screws into), it will display the -AC. This being said, either the thermostat is loose on the wall currently, or your 24 volt transformer has died. Hope this helps.

by what i have found for your model it doesn't have a filter persay. it has pads and they go right under the tank.

got to be a tag with model number. humidistat usually has setting on it with temperatures. Try 40 to start. get condensation inside windows? lower a litltle.
