    The wires connected to the thermostat from the main unit are G Y W RH with a jumper wire to RC , B and O terminals not in use. There are two wires on the Honeywell H46C Humisistat. To what terminals on the thermostat do I connect them to in order to be wired parallel or to get the Humidistat to work properly.

  • rjcream Jul 01, 2008

    I don't know.

  • rjcream Jul 01, 2008

    I will try the G and RC/RH connection later. Will get back if that does'nt work. Thanks

  • rjcream Jul 01, 2008

    Tried the G RC connection, but the A/C unit ran continually.

    Connections and Operation

    A dehumidistat in combination with the thermostat can be

    used to run the air conditioner to control relative humidity

    levels. The dehumidistat and thermostat can be wired in

    parallel or in series.

    Wiring in parallel allows the dehumidistat to independently

    control the humidity level, but could cause

    overcooling of the home. During unoccupied times, the

    homeowner should set the thermostat to a relatively high

    setting and control moisture using the dehumidistat.

    Wiring in series prevents overcooling but the air

    conditioner runs only when both the thermostat and

    dehumidistat are calling. During unoccupied times, the

    homeowner should set the thermostat to a relatively low

    setting and control moisture using the dehumidistat.

Hi,
Thermostat connetion pattern is as follows:
Red, hot side of transformer.
Common side of transformer (See B)
Yellow, Compressor activity (cooling or cooling and heating on a heat pump).
Green, furnace blower fan. (needed for air conditioning, heat pumps and some electric furnaces).
Orange , Energize to cool (used for reversing valve on heat pumps)
Blue or Orange, Energize to heat

    Hi,

    To operate the fan, according to page 2 of the pdf - (4 wire) it's accross G and the RH / RC posts.



    I don't think polarity matters if it is purely a switch contact humidistat.



    This should power the fan on - to circulate air irrespective of temperature.

  • Richard Perkins
    Richard Perkins Jul 02, 2008

    Was the air humid ? if so it was only doing it's job.

    What effect did turning the humidistat up or down have?

HONEYWELL RTHL2310/RTHL221 THERMOSTAT AIR WILL NOT COMEON


Recheck your connections.The wire colors may not have been wired in the standard way when HVAC system was installed. I remember the instructions on my Honeywell thermostat(replaced mine about 2 months ago) stated that you should look at the wire LOCATIONS on the 'stat you're replacing and tag the wires according to this,not the wire color(too late in your case).You'll have to verify the wires.Disconnect them(don't worry about noting where they were as it's not right anyway).Using an A/C voltmeter,locate the hot feed to the 'stat(ground one lead of the meter at a nearby outlet and look for 24v on any of the wires).Tag it as "feed".Now,touch this to each wire until you find one that turns on the ventilation blower and tag it.Try the other two,one of them should turn on the outside A/C condensor unit(this is the A/C wire).The remaining wire's gotta be the furnace,but verify anyway.This should be enough to get you back on track(don't feel bad,the instructions in my 'stat confused me a little,even though I've replaced mine a couple times before).PS- I think the blower fan wire goes to the terminal with the little factory jumper wire-this is so you can set it up to run the same fan in heat or A/C(factory setup) or remove the jumper to run a seperate fan for each(highly unusual setup but possible)

That 's a really good idea. My question would be is that a two wire humidistat? If it is. you would have to parallel the wires. One wire on the "R" on the thermostat and the other would go on "Y" and jumper to "G". Really interesting , I would like to know if it works. I live in Okla. and we have real high humidity summers but probably not like Florida. Hope this helps you.

If you are leaving for SUMMER, definitely do not need to set at 65, that would be tremendous waste of energy. Humidistat in summer should be off. I wonder if he thought you would be gone during winter.

R represents power supply for the heat system.

G represents fan (neutral).
W represents heat system.
Y represents cooling system.
Y2 represents 2nd stage cooling.

It's a little unusual to add a humidifier in Florida. The ambient humidity is usually high enough.

But anyway, if you want to do this and assuming you have central air with forced air heating, you could install the humdifier in a standard configuration, then use a sail switch or differential pressure switch in the supply air duct to turn the humidifier off or on when you are in the heating mode only. The sail or differential switch will ensure that the unit can't run unless air is moving and you can tie the humidistat in to the first heat stage.

Make sure on the furnace that you have the same colored wires connected at the thermostat to R and W. Check for good connections at both locations. You can always test to make sure the unit fires by crossing the two wires together. If the unit fires, you have a bad thermostat.

Honeywell humidistat stuck


what i would do is make sure tha the hole for the wires that go to the humidistat is completely closed and that you are sensing the true humidity for the space also have the tech wire the so that the heat comes on instead of the ac for the de-hiumidification process.

Maybe I can help. this is 24v so it doestn't matter which wire goes where so here goes. 2 wires from humidistat go to furnace, split one of the wires(not both) so they reach the yellow wires on the humidifier. with marettsconnect one of the split wires to one of the yellow wires. do the same to the other split wire and yellow wire. what you should get is one wire from humidistat to furnace then one wire from humidifier to humidistat and one from humidifier to furnace. hope this helps

Humidistat installation question


I suppose you are looking at the do-it-yourself model. Depending on the wire that is run up to you Regular Thermostat from your furnace. You may have to run a seperate line for the Humidistat. A digital thermostat that does Humidity and Temperature is recommended. Or you could just place a Humidistat near the furnace room. A wiring diagram will come with the Humidifier discribing the different ways to wire it.
