changed my batteries in my RTH2300/RTH221 series programable thermostat and thermostat screen/window is blank. I pressed HOLD to reprogram… cannot see what temperature is….. I can hear that the system is on but it feels like the air conditioner and not the heater….even though switch is on "heater". Please advise. Thank you.
