If you are using a single stage with just a W connection not a W1 and W2 then it may be wired to the W1 connection on the furnace contro board. in that case it will only run in first stage. the easiest thing you can do is run a small piece of wire between W1 and W2 on the furnace control board. if you dont have a W1 and W2 connection on the board then its not 2stage, if you have an extra wire at the stat you can get a 2stage stat and wire W1 and W2 individually.

Two stage heating is a method to make your home more comfortable while reducing your energy. Sound contradictory? Well, that's the truth. Two-stage furnaces are designed to operate like two separate furnaces, maintaining more consistent comfort levels throughout the home. Your furnace or air-conditioner maintenance group will be able to give you more information regarding their working, but I'll explain the basic facts.
A two-stage furnace will always start in the first stage and attempt to meet the heating demand. During mild winter only the first stage will be required that to running at about 60-70% of its efficiency.When temperatures drop, the furnace adjusts itself and enters the second stage to meet the demand for heat within the home. With two-stage heating, a homeowner has no need to keep adjusting the thermostat.
IS THIS A NEW UNIT? SOUNDS TO ME LIKE YOU MAY HAVE A CLOGGED FILTER ON THE RETURN AIR SIDE OF SYSTEM, CAUSING IT TO SUFFOCATE ITSELF, & TRIPPING THE HIGH LIMIT SWITCH SHUTTING THE HEAT OFF UNTIL IT COOLS ENOUGH, OR ENOUGH TIME HAS ELAPSED FOR IT TO RESET ITSELF.
R represents power supply for the heat system. RC represents power supply for cooling system. G represents fan (neutral). W represents heat system. Y represents cooling system. Y2 represents 2nd stage cooling. W2 represents 2nd stage heating. AUX represents heat pump.
Try calling 1-800-468-1502. Their english is "REALLY BAD"!!!
Gerge, if you go to website www.energycodes.gov
you can do a heat load calc yourself. Basically, you figure out the sizes of walls, total area of glass. total doors to outside, ceiling area and types of building materials used. It is pretty easy and then you will know for sure. The contractor should be suppling you with one but if not use this, it is free!
Some questions for you, did you adjust the Low stage gas pressure first and is is about 6" W.C.? Then did you adjust the High stage and is that about 10" W.C.? If the gas pressure is correct and the dip switch is on 2 stage, the unit should fire on both low and high fire for about 5 seconds then drop to low stage. If it does not, check the hoses going to the pressure switch for a leak. Test the high pressure switch when the unit tries to go into high stage to see if it is closing. Do not blow into the hoses or you will need new pressure switches. If it proves a closed switch, you will need to check for voltage at the gas valve. If you get none, replace the circuit board. If you get 24 volts at the orange wire hooked to the Hi side of the gas valve, you have a bad gas valve.
Yes. The defrost cycle of a heat pump is actually turning on your airconditioning to heat up the condenser to thaw it out. During this cycle your electric strip heaters "should" be adequate enough to compensate for the a/c being on. At about 30 - 34 degrees outdoor temp there is not enough heat in the air to to adequately heat your home with the heat pump only. Some technitions will use an outdoor thermostat to turn off the heat pump when it is under 34 degrees outside. If you are to cold when its under 34 degrees intall more electric strip heaters.. But if you do this your electric bill may go up significantly.
Welcome to the wonderful world of electric heat pumps (lol).
You need a 7 conductor minimum, 8 will suffice. Depending on what type of thermostat you are using, hard wired or battery will make a difference, some model thermostats have a "C" on the terminal strip regardless of the power being supplied to the thermostat. If your Thermostat does NOT have a "C", and the furnace does not require a common, then disregard that terminal. The Terminal strip on the thermostat and the terminal board on the furnace should be close to this, and let’s assume you have 2 stages of cooling as well. This is a general rule of thumb for the wiring and their correct place. R - 24VAC W - Heat G- Fan Y - Cooling W1- Stage 2 Heat Y1 - Stage 2 Cooling C - Common
