Question about Honeywell Programmable Thermostat Heater
Old thermostat without instructions.
Solution #2 as above worked (thank you very much!) to get to the programming mode, but on mine keeping Function #13 on the default setting of "0" maintained the AIR. Toggling the Temp button to "1" changed the system to conventional on/off at the programmed times.

Testimonial: "It is a touchscreen. I have seen references to the battery being round and lithium CR2450; however, not sure if this is accurate. Does anyone know?"
