I have hooked up all the wires and batteries correctly but the system is still blowing out nothing but cold air and the thermostat is a newly installed system

Thermostats don't actually blow anything, the heating system might though. Check the breakers for your heat system, then call a heating specialist. They're really not that expensive.

apparently who ever did the wiring installation did not use the Proper color coding when they did the install. Now you must trace the wiring to the appliance and wire accordingly.

Sounds like the thermostat is hooked up wrong. If the ac doesnt work right its in the thermostat programming or the wiring. Hope this helps good luck

Should have a 5 amp fuse on red wire in between transformer and tstat. If not put one. This will protect transformer. Turn power off and take a good picture of tstat wiring. Remove all wires to the tstat. With the air handler wires join fan and red. (Likely green) let run. Then add compressor and reversing valve ( if reversing valve is energized in cooling ) which in most cases it is. Should then have cold air. Let run. If no problems you know it's outside of the machine. Tstat or wiring. Hook inside of machine all back up to tstat wires. Do the same thing with the tstat wire inside the thermostat. If no problems, must be bad tstat. Hook everything back up right. If fuse blows or transformer because you didn't put the fuse, then you know for sure it's the stat. Good Luck

Heat pumps require a reversing valve for heat operation on the outdoor section, a control signal to a "O" terminal or orange wire is required for heating and cooling depending on the thermostat and out door unit requirements. The thermostat also has to be heat pump type for the system to operate heat for electric system with heat strip, two stage electric heating.

Hello, locate and move the thermostat sensor end(bulb) to a different location.

if you hooked up yhe wires on the heating element check the thermostat it will be a oval shapef unit on housing of element and has wires going to it it may be bad.

This is a wiring issue or you have a heat pump and the reversing valve is stuck.

It sounds like your reversing valve energizes the opposite from how you wired it at the thermostat. Check the instructions.
