If two systems to control can you buy two combo sets? how does the base know which Thermostat to take direction from? like a code that must match

If you have two thermostats you should buy two combo sets. You can set a code to control each thermostat and unit. I have more than one and it works fine.

If you have 2 collars, you can set both to recognize 1 controller. I have done it.

Depends on how many wires , your voltage and wattage. This thermostat uses a two wire setup. It seems like you might have 4 in which case it wouldn't work. Maybe check out the Honeywell site for more specific information and the manual on it.

If the controllers in the AC units and the controllers in the heating units are compatible with the 5 button thermostats it will work, you better check the part numbers on the controllers (inside the units themselves) and call Dometic and make sure, these units are very specific with compatibility, even with other Dometic models and years. Their service dept is very helpful so you won't end up with very expensive book ends.

Robert, you can place this unit in any room and it will communicate back to the "base" installed where your thermostat was regulating your heat/AC. For example, in my case the thermostat controlling a bedroom and two guest rooms was in my main living area which is controlled by a separate thermostat, didn't make much sense. So I purchased this unit, replaced the thermostat with the wireless base and now put the thermostat pendant in the bedroom accurately controlling temp. in that room. Or, when I have guest I put the pendant in a guest room. My only complaint about this unit is the temperature shown is actually 3 degrees cooler than the actual room temp., however we just adjust accordingly but it's kind of a pain having to explain to guests. Hope that helps.

Is your question that you want 2 units with matching keys? I would suggest you wait till the company responds to that.

i found that manufacturer says you can only use one system, but some user are using two system without problem. that's what i've found so far.

I answered this from mu iPhone, but I'd like to add something. If the area of the heated area is so large that two thermostats are need, I would suggest splitting the areas and have one thermostat for each area. There is no way you can have two thermostats for the same floor. That would be like having two thermostats for the same furnace. :)

SINGLE POLE thermostats have one wire that breaks only one side of the power supply line. The control knob will have a low temperature setting, but no "OFF" position.DOUBLE POLE thermostats have two wires and break both sides of the power supply line. The control knob will have an "OFF" position.I recommend douple pole.

Jeff is correct. Only two wires (conductors) are needed. If you have thermostat wire with more than two conductors, no problem, just use two of them and ignore the rest.

Hi there. My iphone app has dropdown for which thermostat. I only have one, but that would suggest the app controls as many as you want.

No. Sounds like the timer switch. More expensive. The 2 thermostats control the heat and extreme temps. The timer on an older dryer is the main knob that you turn to select what type of load you have and how much time.

I think you might need the next model up (with a W2 terminal) for your system: TH6220D: For up to 2 Heat/2 Cool systems

You need to have one of the multi-zone controllers and receivers attached for it to work correctly. If the HVAC systems are in different locations, then you need separate controllers that have the builtin receiver. I have the 3-zone unit (only using 2 zones currently) and it works great! All thermostats must be on a separate channel and "associated" with a separate zone. They cannot be on the same zone. These run on Honeywells proprietary Redlink protocol and are not compatible with other wireless protocols. It is a very solid system though... I did a lot of research before I took the leap. It's Pro stuff. Hope this helps. You need to have one of the multi-zone controllers and receivers attached for it to work correctly.

Most thermostats are common but, the wiring has to be checked. comes with diagram and color coded wires. I up-graded from a slide type thero to the digital one for better control of the temperature. Check the wires with what they do (power,ground ,high temp.etc.) and replace.

You can set each switch to have its own unique code via the dip switches on them. That way they do not interfere with each other.

I don't know, all i do know is I have a gas heater and air conditioner combo unit. the old thermostat was a four wire round mercury switch. this one does work great. i am not a expert but i would guess a thermostat is a thermostat, it checked the temp and then applies power to the unit as needed. I hope this helps. my power bill has gone down also.
