How do I wire this so that either it or the thermostat or both will turn on the A/C?

I do not know what kind of A/C you are talking about. If this is central A/C, probably another solution is needed that incorporates the humidistat with a "smart thermostat." If it is a room/window, unit I would check the load/amp rating for the humidistat and compare it with the A/C draw. The Air King DH55 controls a 120/110 volt circuit and most room thermostats are low voltage applications. This is one I would get in touch with the manufacturer about.

Note that turning on the A/C to control humidity will not work. It will only lower the temperature in the area and can actually increase the RH in that area. If you are controlling a dehumidifier that is different, as it first super cools then reheats the air to the desired temperature to deliver the required humidity and temperature. If you really want to connect the humidistat up the answer depends on what type of thermostat you want to connect to? If it is an older Heat/Off/Cool type there is no easy way as the connections you need are across the cool side of the selector switch to the yellow wire which is the cooling control wire (typically yellow but color can vary). Since the cool side of the switch is internal to the AC thermostat it requires some soldering to modify, it can be done but since you are asking the question I assume this is not something you would be comfortable doing. If you connect across the Red and Yellow you are bypassing the switch and possibly the fan control. Thus the A/C may run but the fan may not.

I don't recomment it use for control A/C. It works differences of humadity.

Yes, turn on air conditioner and use the code for Sharp. it is three of them. Try them one at at time as the directions states. If that doesn't work, press the setup button until the red light stays on, then press 8. Next keep pressing the power button until the air conditioner shuts off. Once that happens press the number 1 to install the code.

It's been a while since I installed, but I think if you don't install the common wire you will have a battery operated thermostat. If you have the complete 24 volt circuit, (Common installed), batteries will be the backup, in case of AC power failure.

check to make sure your wires are hooked up correctly mine works just fine for the air conditioning

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.

Sorry, I really don't know. It is so simple, and the cost so low probably worth a try. It would cost more to have an A/C person come to install a more expensive one!

I never hooked mine up to the existing thermostat. There is one built in to the unit.

Wire it to a toggle switch, or put a inline fuse on it and remove the fuse when not in use

There are multiple wiring configurations included in the unit's instruction manual, I would suggest searching the web for an electronic version and downloading it to see if it includes everything you need, or contacting Honeywell directly.

These 5 answers are only half correct ,you can use thermostate . THey can be wired to turn on and off with heater set to a certain temp.

Hey Larry, When I turn off the A/C manually while it is on, it does not turn ON automatically when the on tab comes around. You have to turn it ON manually.

Turn your wires around rewire it up. make sure it's grounded right on both sides

Not sure whether or not they can. Can you provide more details as to what your trying to accomplish by having 2 thermostats.

Providing it has a battery just run the + wire to the + on your battery and then out a toggle switch in the wire to turn on and off. and then just run the - wire to the - on the battery it simple and easy!

If you're only controlling heater, then use a 2 wire heat only unit like this one:Heat Only Digital Non-Programmable Thermostat

You're on your own for the control cable. You need a light gauge 3-conductor cable (thermostat cable will work), the power supply is only one Amp.

Just plug it in and it turns on with one light. When it is ready, then both the lights are on.
