Do you have a manual for the Alerton TS-6000?
SOURCE: HEATER TEMP CONTROL IS STUCK ON HEAT. WILL NOT SWITCH TO COOL
sounds like your blend door actuator has failed, or the lost vacuum to this actuator, or something got into the vents holding the blend door into position. Most common is the acuator failing, good news is its a fairly inexpensive part, but gettin to it is not fun, its it the ductwork in behind the dash, I'm not sure on your specific model but most I have seen the dash has to come completely out. If it gets to that point you may want a repair shop to do that.But hopefully you get lucky and its easy access.

Assumed all the wiring are correct,
to change from manual switching from heat to cool, press [system] button ( left ) to go into system setting.
then press and hold the [fan] middle button untill option display 120
use up down button to select option 300 ( Manual/Autochangeover) ,
select 0 for manual, 1 for automatic. ( read caution in page 22 of installation manual )
Good luck

There should be electric heat strips in the airhandler.
They automatically come on when the unit goes into defrost, the thermostat is turned up more than 7 degrees over the indoor temp or if the outdoor temp is just so cold the HP cannot keep up.
Tat is your auxillary or emergency heat.
What does the new t-stats installers booklet say that the 0170 function and #2 #7 options are for?
If it is for gas vs elec heat then set it on the elec option.
The difference is that in gas heat systems the blower comes on a few min AFTER the furnace fires up to allow the heat exchanger to get hot.
In an electric furnace the blower has to come on emediatly because the heat strips get hot emediatly and if the blower is delayed the system will shut of in high temp overload.
SOURCE: I CAN EITHER HAVE AIR COND. OR HEAT
your actuatior valva is bad.you can order 1 from auto parts giant online for about 45 bucks the dealer wnats 240.00 that will give the heat and air back
SOURCE: "cool on " flashing..no heat or cool air blowing
when its flashing its in a 5 min delay mode if you wait 5 min and still flashing you may need a new stat. but give it a full 5 min.
The reversing valve is energized in the cool mode of these AC's. So there is no real way to bypass it. I would check the thermostat and the control board in the unit to make sure that the switches are set correctly.
