Customer Question

Hi my thermostat display is blank. Replaced the batteries with new ones and cleaned the terminals. I still have no display.
JA: Thanks. Can you give me any more details about your issue?
Customer: I have a Chronogyr Rev 15 thermostat. I went to turn the thermostat on but the display has nothing on it. I replaced the batteries and then reset holding down the appropriate buttons and still have no display.

Russ here. If thermostat is blank. No display is no power to thermostat. You have changed batteries and reset thermostat. You have bad thermostat. Replace thermostat. Power surges and even static electricity will cause this problem, Russ
