Moved in to a home that used to have a package heat pump unit that the owner sold, got a tempstar 3.5 ton with heat pump (ph5542akaz) hooked up all electric, but ran into trouble with old thermostat already installed (white rodgers-1f56n-444) have 6 wire in wall only 4 were hooked up. Can some one give me a start from scratch diagram the wire colors I have to work with are red, yellow, green, white, brown, and blue. The unit calls for orange, I used the blue in the wall hooked up to the "0" terminal (now 5 wires hooked up) and everything seems to work but the air from the vent is warm at best.

Ph5542akaz This is not a model number

The thermostat you picked will not work for a heat pump with electric or gas heat as the second stage. I am sure you should have electric or gas back up since it is very rare to install a heat pump without it. BTW the wiring specifications are also on the link.

It is a tempstar PH55 series 10 seer package unit with heat strips 3.5 ton this is there model number PH5542aka. How did the previous owner have a heat pump (almost identical unit installed by ac tech) hooked up on this t-stat. went over to his house many times and was working with no problems

how did the previous owner have a heat pump (almost identical unit installed by ac tech) hooked up on this t-stat.

I have no idea unless the heat pump does not have any electric heat in it. If it does not have any electric heat then just follow the diagram for the thermostat and the units terminal letters for the thermostat wiring.. It is very simple if it does not have any additional electric heaters installed in the outside unit.

NOTE you are not going to have real hot style heat from a heat pump UNLESS it has additional electric heaters installed in it.

It does have 9600 watt heat strips but the old one did also he paid around $400 to have them installed. This would be the electric heat right?? Can you tell me which t-stat to buy and how I should wire it the unit I got was used and the low volt wires were just a tangled mess but I used the wire diagrams to sort it out... I think... I'm still confused to where the orange hooks up is it be terminal or o terminal?

Is there a way to wire it to bypass the heat strips till I get the new t-stat, I don't need a lot of heat, I'm in Florida but it has gotten to around 30 degrees lately and if this could get a little heat for now it would be nice

First off the unit will need a 50 amp minimum ampacity circuit and a 60 amp breaker for the electric heat. It will also need a circuit for the heat pump section. You better check your 240 volt wiring before you hook up any thermostat. The wiring is listed in the spec cut sheet you provided in your link.

What the link did not contain was the low voltage wiring hookup. I have no idea what you have there now in the tangeled mess but you said you used the wiring diagram somewhat so you have the diagram and I do not so my suggestion is to follow the diagram. The orange hook up depends upon weather the heat pump reversing valve coil is activated in the A/C mode or heat pump mode. That is a guess if it is not on the wiring diagram. If you try it one way and it does not work then it will stay in the A/C mode so just change it.

is there a way to wire it to bypass the heat strips till i get the new t-stat,

Yes just unhook them from the power source.

Have a 50 amp breaker #6 thhn copper feed to ac unit, and separate 60amp breaker #6 thhn copper feed to 60 amp internal breaker inside unit for heat, I have the manual for the installation but it is to big to upload I'll see if I can find the link. The t-stat wires in the unit are hooked up as green to green (fan?) red to red (24v transformer?) yellow to the two yellows in unit (compressor?) white to the two whites in unit (heat?) and grey, brown, blue wired togeather in unit not to t-stat wire. that is what I got from the wiring digram let me know if it is wrong. I had the orange left over (reversing valve ?)
In the t-stat I wired like this green to g, yellow to y, white to w, red to rc has jumper to rh, previous installer moved factory yellow jumper from why to a (?) and I tried hooking orange from unit to o on t-stat but had no change

Can anyone suggest a decent priced digital t-stat that will work with my package ac/heat pump/heat strip unit.

Got the ac/heat pump working fine for now without the aux. heat strips but don't know what to set the anticipator at, the instructions for the unit say to set it at what the t-stat instructions call for, and the t-stat instructions say to set it at whatever the unit calls for?? It is set at .4 and is adjustable from .15 to 1.2
