Question about Heating & Cooling
I have set the thermostat at my house at set on auto at 21 degree. However since this morning the temperature increases to 26 degrees and beyond and not coming down. The house is quiet warmed up, so please advise on issue and troubleshooting

Sounds like there is a problem with the a/c and not necessarily with the thermostat. Is the outdoor unit running and discharging warm air? If its running and the air is cool, either the compressor itself isn't running or there is a refrigerant issue.
Verify what the system is doing, then consider contacting a reputable service organization in your area.

The problem is likely with the cooling system, not the thermostat itself. Either the message from the thermostat is not being received by the AC unit, the solenoid isn't turning on the unit or it can't cool properly.
First check that none of the wires to the thermostat are loose or broken. You'll have to take the face plate off to check. The conductors are very small wires and can break easily. Depending on the unit,there are 4-5 wires usually for a HVAC system. If a wire is loose, reconnect it (push it in or screw it down gently). If a wire is broken, strip (for screw terminals) a new section and reconnect it. Check for ice build up on the condenser coils. (That is often a sign of a refrigerant leak. You'll need a professional to fix it and recharge the unit.)
Do you hear the fan running? If you do, then the condenser is a likely culprit. If the fan isn't running, then the control board for the system may be bad. You may want a professional to check the system. If you tell them the make and model, the technician can bring the parts if it is a problem with the control board.
I hope this helps.
(We had the broken wires to our thermostat in the winter. A few years ago, a nearby lightning strike had the AC off in the summer due to the control board damage. The house reached 90 degrees while we waited for the repair.)

SOURCE: I changed my wireless setup and router, now the thermostat says connection lost, I followed the instructions to reset but the WiFi set up doesn't come up How do I reset the Wifi I have the RH
Be sue the router is on and is not blocking it.

I would say that the problem is in the furnace, not the thermostat. The Thermocouple or other temp sensor needs replacing, the sensor that tells the furnace that it is heating. It just keeps turning off and trying again in 3 minutes cycles.

SOURCE: I install 2 new honeywell non programmable thermostats. The temp never reaches the setting temp. Always 5 to 8 degrees off. I can not get the furnace to heat the home over 70 degrees. Even set at 80.
If the furnace is cycling on and off and not reaching temp there is a problem in the control circuit. If the thermostat is not satisfied the furnace should be running without shutting off in which case the capacity of the furnace is inadequate because of size or problems reducing the capacity. This could be caused by an increase in home size, poor air flow (dirty filter, loose fan belts, fan running slow, obstructions in the duct), dirty heat exchanger or burner, reduced gas flow, over temperature switch bad causing the burner to shut off early, or a few more technical reasons. You may do well to call a technician to troubleshoot this problem.
