I have an Aprilaire 8570 thermostat that is blank and won't

Customer Question

I have an Aprilaire 8570 thermostat that is blank and won't come on. I've check the circuit breaker and reset the breakers labeled AC. I've also flipped the emergency switch on the furnace. The thermostat doesn't require batteries. Is there anything I can do?
JA: I'll do all I can to help. Is there anything else the HVAC Technician should be aware of?
Customer: Not that I know of.
JA: OK. Got it. I'm sending you to a secure page on JustAnswer so you can place the $5 fully-refundable deposit now. While you're filling out that form, I'll tell the HVAC Technician about your situation and then connect you two.

many units have a water safety switch which cuts power to the thermostat. Especially if in attic.

Do you know if your unit has this switch safety?


Customer: replied 1 year ago.
I don't know. The unit is located in the basement.
