It will more or less fire immediately in stage 2.

I would still tell you to get an outdoor temp sensor...

Only initially when the stat is "adjusted" to 2 degrees or more above the current set temp will aux heat come on. once it reaches the set point, it will not use aux heat very often, only if the stat...

First of all, I would highly suggest installing an outdoor temp sensor, as that will eliminate all of your issues. I know it has been said before on this thread, but that is truly the only way for...

Honeywell doesn't offer anything like that...

Everything internally to the stat will take care of the CPH, that isn't causing this. when you set your CPH to 3, the stat knows how much time is required to maintain the +/-1 (if you search rog09,...

Please post all of your settings pertaining to Dual Fuel. If it is setup correctly for Dual Fuel and it is set for balance point only, it will not call the Aux for any reason above that if the 2...

The stat does not have a slab sensor and using the existing indoor air sensor won't work as a slab sensor (different algoritms, type of sensor, etc is needed)

The VP IAQ hum sensor is "spec'ed" to +/- 5%, but in reality it typically is +/- 1%. There is a calibration in the product if there are differences throughout a home (e.g. the stat is located in a...

In VP IAQ, the L terminal is only an input. Therefore, the only time you will see the red LED illuminate is when there is 24V on the line (e.g. a HP monitor that senses a fault condition and closes...

has anyone ever thought about making a sticky out of this two-stage furnace and single stage stat issue? Then each time a homeowner or contractor asks we could just forward them to that area where...

RE: sensor location

It is very important where you locate the remote sensor. The best bet is to find a place out of the sun where it can get some of the breeze. Typically, the best place to...

As mentioned above, the overcooling can be adjusted. It can be set to overcool by 1, 2 or 3 degrees. Or, as indicated above, it can be set to 0 degrees and it will simply lower the blower speed...

Not exactly an anticipator setting, as it uses P+I control for staging. However, for longer run times, the CPH could be turned down and/or the "heat aggressiveness" could be turned up, but that will...

The VP IAQ (or VisionPRO 9000) requires only an outdoor temperature sensor to control all of the dual fuel capabilities. It makes installing the heat pump easier (it is a two piece solution that...

The stat will handle up to 4 stages of heat and 2 stages of cool...plus humidification, dehumidification and ventilation. The controls for dual fuel are also better than anything on the market, so...

As already suggested, the VisionPRO is a superior stat to the 9715i. Depending on the install you are doing, I would highly recommend getting the VisionPRO IAQ (p/n YTH9421C1002). The stat will...

vibration - if you read through this thread and search for "CPH" or "cycles per hour" you will find an in-depth discussion of what it does

Go to page 32. That is the most we can legally say about P+I control and there is a diagram that better explains how it...

If you had a good contractor you wouldn't have had to worry about asking questions b/c he would have done it right the first time...hence why we are here to attempt to help. The more of the industry...

I talked with a guy that now works for us that used to install Carrier and he said he knew nothing about those heat pumps that would preclude you from installing a new VP IAQ or some other newer...

"wires" is referring to the number of wires that came in the "bundle". in your case, five.

what are the four wires connected to? you should have...

"Facts" 1-5
1. untrue from how it controls it. that is how 'droop' stats work, not droopless. true that there is no 'mystery' behind how it works...unless you call...

When the defrost cycle runs, the unit goes into cooling mode...

In very simplistic terms (not actually how it works but general concept), when the cool is on, the unit takes heat (and moisture)...

if you already own both, the functionality is going to be somewhat similar. the 6220 will get you a 5 year warranty and tech help from professionals, whereas the retail version will require help...
