Hi our system works great! But during the summer our thermostat broke and replaced it with ritetemp 6022 model. The a/c worked great, but now winter is here and the heater wont turn on. I need to know where I can go to find out what my 4 wires do. I have white, green, red, and yellow. But I understand that they can mean anything. I thought that we connected the wires from the old thermostat the same, but apparenlty not. Pleas help we live in South Texas and are not use to 50 degree weather, My kids and I are freezing.! Thank You, Norma

Wiring color to Thermostat
Depending on what thermostat youhave and existing wires. Typically red and white are for heat and yellow andgreen are for cooling. On base of thermostat there should be initials stampedto identify wires by color. R. W. Y. G. Possible Rc. and Rh if so for most usesyou need to jumper these two together. You may have a blue wire instead ofyellow or green. If so just hook blue to y or g. Is it helpful?.
The rh and w wires should not be on the same screw. That would make the heat run all the time because it would bypass the thermostat. It sounds like you had power on the rh wire which is the hot wire from the transformer. If you connected it to w and the heat still didn't come on then your problem isn't the thermostat. You should check the contactor or relay that makes the heat kick on. I don't know what type of system your thermostat is controlling so I can only give you limited advice on that.
Tried this on my unit today, and observed the same results, but got Aux Heat (with A setting), if the H (blue wire) connected to B terminal, as per instructions for my 6036 Ritetemp. However, in this case, when the set temp is reached, I hear the click, but HVAC still blows aux heat indefinitely.
I also have RUUD UBEA 17J10..., and replaced my old honeywell with 6036, and can't get heat pump working. Both of my units are 14 years old, so I'm thinking to replace them soon.
is the system zoned? if so maybe the zoning control board to the damper motor is wired improperly. when a system freezez its because of 1- restricted air flow across coil, (maybe dirty filter) or 2-low refrigerant charge. again could depend on how its zoned.
I would suspect if there is no power to the R terminal on your thermostat that the power is off at the furnace, or the 24 volt control transformer is bad. Check from R to C on the transformer for voltage with a meter with the power on to the furnace. If you have no power reading of 24-28 volts between R & C replace the transformer.
You may have to remove your filter & look for a model # of your unit, so we can pinpoint your wiring to the thermostat. Usually the terminals on the thermostats are labeled -RC-RH- etc, and you simply move old to new of the same. A lot of times some manufacturers will use phone cable form AC unit to thermostat, and mix up the colors, that's the reason for going to the AC and see what color is used from there. It could be red from control box, connected to green wire to thermostat for example. Thats where you note it and wire accordingly.(terminal calling for red wire, would now be green) If your stumped, get back to us with that model#.
On a furnace the fan is controlled by a computer and a sensor ot a oldstyle fan thermostat. Basically it waits till the furnace heats up a little and then turns it on and after it shuts off it will run till the thermostat cools back down may take a few mins. In cool mode the thermostat controls the fan so it shuts down immediatly. This is why the thermostat asks you if its electric or gas heat. Should have a switch somewhere for this.
