    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?

Yes leave the C off if it is battery powered the only time you use the C is if it isnt battery powered.
Just to let you know LUX is an awful brand of t-stat they have a lot of issues with them. As a general rule always stick with white rodgers or honeywell stats they are made very well and reliable.

Tip

Unlock Lux 1500 Thermostat


Your Lux 1500 thermostat is showing the “lock” code and you cannot change your program. How do you get the thing to unlock so that you can make changes. The answer is actually very simple.

Hit the “next” button three times, then hit “hold” this will unlock your Lux 1500 thermostat.

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.

There should be a jumper wire connecting both together, or a metal piece connecting RH and RC. So you should be able to connect it to both. That solves that problem as for the other I'm not really sure at the moment but I'll look into it and get back to 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.

The honeywell THR830TUK thermostat does not require a neutral as shown in the instructions.Connect the LIVE to terminal "1" and your YELLOW SIGNAL wire to terminal "3".
Connect your EARTH (if you have one) to the EARTH connection on the top left hand corner of the thermostat and blank off your NEUTRAL wire with a block connector.These instructions were supplied to me by Honeywell Customer Support.Hope this helps.

Thermostat wiring


99.99% of the modern residential units use only one transformer to power the 24 volts for both the furnace and the a/c unit. It will be located in the furnace. The outdoor unit will not have its own transformer unless its reeallllly old. Place a small jumper wire between w1 & w2 terminals on the thermostat. (The lux brand is not the professionals choice) (if you have problems replace with a honeywell or white rodgers brand).
Good luck.....
