Are these two Honeywell thermostats the same TH8110U1003 and YRTH8500D1024?

I am going to say no. TH8320U1008 and YRTH8500D1024 look to be the same. If you notice the number of Stages that each controls, is what I am basing my guess on. TH8110 only controls 1 Heat/1 Cool. Both TH8320 and YRTH8500 control 2 Heat/2 Cool.

If the main motor fails, the instructions say to turn on the auxiliary motor.


Why does the HVAC thermostat say that the heat is on when it isn't and the air conditioning works perfectly?

All that thermostat indication is saying is that the heat is supposed to be on. If you hear the fan running for a minute or so after the heat indicator has gone out this is normal as the fan is blowing out the remaining residual heat in the furnace after the flame has gone out. The same works in reverse once the stat indicates a call for heat the fan does not start for a minute or so to allow the furnace to heat up and not to blow cold air into the space at start up.

Your 1999 CRV temperature gauge keeps working on and off also the heat does not get real hot unless the gauge is working do you need a new thermostat?

It sounds like the guage is working fine. Since you have little or no heat when you say the guage isn't working it sounds like the thermostat is getting stuck open causing your coolant to be constantly cooled (it isn't closing so the engine can warm up sufficiently to provide heat). Replace your thermostat and I bet your problem will go away.


What does the EM heat mean on your thermostat for your central AC heating unit?

If you have a heat pump A/C unit then you have auxillary heat and emergency heat. The EM stands for emergency heat, which is using only your electric heat strips or gas heat, depending on your system. The auxillary heat uses your compressor inside of your outside unit. Say the house is 60 degrees inside and you set your stat to 70, the temperature difference is so great that if the heat pump alone cannot satisfy, then the auxillary heat would come on to assist the heat pump. Say you were to get a leak in either your condenser or evaporator coils, your heat pump would not work on the regular heat setting on the tstat. In this circumstance you would want to use just the emergency heat until a service tech can evaluate the system.
