SOURCE: No heat coming from central heat/cooling system after install

Hi,
Yes add the jumper from the Rc to the Rh terminals. the Rh feeds to the W and that is what turns your heat on!!
Also leave the HG wire exposed you are running elelctric heat so you want the cycle rate to be for electric heat "HE"
And no You do not need the "C" wire with that t-stat, just make sure that it cannot touch any of the other wires or you will burn out your transformer in the heating unit.

I hope that this will help you to solve your problem!

Thanks for using Fixya!!

SOURCE: Honeywell RTH230B cooling problems...

I printed out the instructions for your thermostat. It looks like you should have the following.

There should be jumper wire between Rh & Rc

Red wire to Rh or Rc whichever is easier since there is a jumper. This is the hot wire and all the thermostat does is connect to route it to the components needed for heating or cooling.

Blue wire, tape it up and don't use it. There is no spot on this thermostat for it. It is only used on thermostats that are powered by the transformer.

White wire to W. Powers the heat relay

Yellow wire to Y. Powers the cooling contactor

Green wire to G. Powers the indoor fan relay

There is a black jumper on the back of the face plate. Look at section 2.4 Setting J2 Jumper in the installation instructions. Make sure you have it in the right position for what you have. If you don't have them just google them.

Hope this helps.

SOURCE: I am wiring a honeywell thermostat model number

there is it all depends on how many strands of wire are in there, they start at 2 wire and go to i think 8 wire and maybe more.
The wires are as follows:
1. red = power to stat.
2. green = fan control
3. blue or yellow = ac
4. white = heat
w1 = 1st. stage heat
w2 = 2nd. stage heat.
i am on line if you have any questions. wally

Need help wiring a thermostat with 5 wires don't know what rh and rc mean.and how they connect. thanks


Hi, on a thermostat like you have, the RC and Rh have a jumper wire that connect the two using the red -hot wire coming in. This means R-cooling and R-Heating. So, take the red and connect to either one, and make sure you use a jumper wire to connect rc and rh together along with the red wire coming in. Yellow will go to Y for cooling, W for heating, and G,green for the fan. If you have a blue wire left over, it is a spare, unless you have no yellow. If it doesn't have a yellow, use the blue wire for cooling. Some contractors will use blue instead of yellow. If not, the blue is a spare wire.

Alternate Wiring

If a labeled wire does not match any terminal

designation, see diagram below.

Do not use C, C1 or X wire. Do not use B wire if you already

have O wire. Wrap bare end of wire with electrical tape.

This thermostat cannot be used if your old thermostat had

any two of the following wires: R, RC, RH, 4 and V.

Place a jumper (piece of wire) between Y and W if you have

a heat pump without auxiliary/back-up heat.

Set jumper JP1, on the back of the thermostat, if you

have connected a wire to the G terminal.

Incorrect jumper setting: An incorrect setting is

noticeable in a gas or oil heating system. When heating

starts, you will initially feel cold air coming out of the vents

as the fan is running before the furnace has enough time

to heat up the air.

I paid $20 last night to talk to someone. He told me how to hook up the Lux DMH110 but when i hooked it up this morning the heater came on when i put it on COOL and the fan just come on when i put it on...


If you have this type of system your thermostat will not work;
  • Multi-Stage Heat Pumps
  • 3 Wire Hydronic Systems
  • Line Voltage Systems (120/240 VAC)

  • This thermostat is only for this type of HVAC systems;
  • Most 24V Heating and A/C Systems
  • 1 Stage Heat/1 Stage Cool: Gas, Oil, Electric, or Single Stage Heat Pump Systems
  • 2 Wire Heat Only Hydronic Systems (Hot Water Baseboard & Radiator)
  • Millivolt Systems (Wall Heaters / Furnaces & Gas Fireplaces)

    1. Never connect a low voltage thermostat to line voltage.
    Two wires control a heat only system.
    1. Connect one wire to W and the other to RH.
    Two wires control a cool only system.
    1. Connect one wire to RC and the other to Y.
    Three wires for forced air heat only system, where the previous thermostat
    did not have a clock or timer.
    1. The previous RH or RC wire is the 24-volt transformer wire. Connect it to RH. Leave jumper connecting RH to RC. Connect the forced air heat system to W, and the fan wire to G.
    Three wires for a heat only, forced
    water system that did NOT have a
    clock or timer.
    1. This system employ 3 wire zone valves. Currently no Lux controls are compatible with this system.
    Three wires control a heat only, forced water system that DID have a clock or timer.
    1. Tape off and do NOT install any clock or timer wire. Often they are labeled C or TC. Install the remaining two wires, one to RH and the other to W.
    Four wires control a heat only system,
    and two of the wires operate clock or timer. The other two wires operate the heater.
    1. Tape off and do NOT install any clock or timer wire. Often they are labeled C or TC. Install the remaining two wires, one to RH and the other to W. The jumper connecting RH to RC may remain or be removed.
    Two wires control heating AND cooling.
    1. Currently no Lux controls are compatible with this system.
    Three wires control heating and cooling. One wire operates heat, one operates cooling and the third provides 24 VAC.
    1. Connect the 24-volt power wire to RH. Install a jumper connecting RH to RC. This jumper is usually pre-wired. connect the heat wire to W, and the cooling wire to Y.
    Three wires control a cooling only system. One wire operates the compressor, one operates the fan and the third provides
    24 VAC.
    1. Connect the 24-volt power wire to RC. Connect the cooling wire to Y and the fan wire to G.
    Four wires control a heating and cooling, electric, gas or oil, forced air system that
    is NOT a heat pump.
    1. Connect the 24 VAC transformer wire to RH or RC. Install a jumper connecting RH to RC This jumper is often prewired. Connect the heat wire to W, the cooling wire to Y. and the fan wire to G.
    Four wires control a Single Stage Heat Pump. They were labeled: G, Y, R or
    RH or RC, With either B or was used.
    1. Do not connect wires to both B and O. Connect the reversing valve wire to B or O, just as the previous thermostat. Install a jumper wire from RH to RC. Connect 24 VAC wire to RH too. Install a second jumper wire from W to Y. Connect compressor wire to Y and the fan wire to G.
    More than 4 wires are connected to the
    old thermostat

    All electric new home. Bought honeywell programable thermostat RTH2308. A/C works but heat will not turn on. This model # is not on their web site.


    check to make sure there is a jumper wire on the subase between "rc" and "rh". these designations stand for red/cooling and red/heating.they are used independently if the system has a separate control transformer for heating and a separate one for cooling. they need to be jumpered when one transformer is used to control both modes. your fan "on" switch won't work the fan continuosly if there is no connection to the "r/c" trminal.
    on the back of the thermostat there should be a switch you need to select for gas or electric heat. or there are small micro switches that need to be set for your particular application.check your installation papers for details.
    these thermostats usually cover a wide range of applications and need to be selected.

    Just installed the honeywell thermostat. the ac turns on, but not the heat. what do we do?


    Some of the thermostats from Honeywell require a jumper wire on the thermostat between the RC and the RH connection for the heating to operate. It is possible that your installation needs this jumper wire installed for the heating to work.Verify that this jumper wire is installed if your thermostat requires it. If it requires the jumper wire and you do not have one you can cut a small piece of existing wire on the connections to make a jumper wire. There are also some thermostats with a jumper switch for electric heat and gas heat...make sure that it is on the proper setting.

    I bought a Honeywell programmable thermostat RTH2310 to replace my 10 year old Honeywell thermostat. My old thermostat is a 4 wire system but also has a jumper from Y to 1. New system does not tell me what...


    It depends on the type of thermostat you have.
    Do you have a 4 wire or 5 wire T'stat?
    The red jumper wire was for a 5 wire t'stat with 1 transformer, the red jumper actually should have been from R to 1.
    So you need to trace the wires back to the furnace and make sure they go to the locations identified below.
    if you have a 4 wire t'stat then you don't need that jumper, if you have a 5 wire t'stat then you do need that jumper but it should go from Rh to Rc.
    4 Wire Termostat
    R = Red One Side of 24 volt Transformer
    G = Green Blower
    Y = Yellow Cool
    W = White Heat
    5 Wire Thermostat
    with one transformer for both units
    Rc One Side of 24 volt Transformer
    Rh Jumper Rc to Rh
    G = Green Blower
    Y = Yellow Cool
    W = White Heat
    t'stat?

    I want to change to a programmable thermostat my old one is 8846 and i need to have a wire diagram in order to change wire or its a lr1620 might be the model


    • Red to the thermostat RH or thermostat RC terminal with a jumper wire between thermostat RH and thermostat RC. Or Red to the thermostat R terminal which is shared with both the heating and cooling. It has an internal jumper built in to the sub-base. The red wire is the source hot wire from the transformer. All other wires, except the common wire, controls a specific relay or contactor that energizes the fan, heating, or cooling depending on the selection. The following is the common wiring colors but your system may not be common and different colors could have been used.
    • Green to the thermostat G terminal. This is the color that controls the fan or the relay that control of the blower.
    • Yellow to the thermostat Y terminal. This is for control of the air conditioning.
    • White to the thermostat W terminal. This is for control of the heating.

    Old thermostat wiring doesnt match up with new thermostat


    Look at the instuction booklet (or on the T-stat board) for a switch for the reversing valve.

    Some systems reversing valves are in cooling mode when energised, some are in cooling mode when NOT energised.
    You are looking for the switch (Usually very tiny, or a different jumper setting) that will change the position of the reversing valve when calling for heat/AC.

    This is not a switch like the typical "ON OFF AUTO, HEAT COOL EMG HT switches. It will be on the board itself or the back of the T-stat.
