Question about HAI Omnistat2 RC-1000 Thermostat

1 Answer

Leviton RC 1000. I replaced the old HAI thermostat with a new RC 1000. Four wires to drive furnace and AC, there was no common wire attached. I also connected the thermostat to my HAI controller per the wire diagram although the old thermostat had a 4 wire plug, the new one needed hard wiring. When I plug the thermostat into the base plate and power on, the display just flashes blue then off then blue, etc. I so not see any numbers or names, just a blue screen flashing every second. I have disconnected the wiring to the controller and have the same problem. Thanks

It might not be compatible with the furnace and ac system you have. I would make sure that it is, also read the manual book some wires you can tie in together to plug into the same lead. JUST FYI AC and Furnaces are really fancy now and have a computer chips in them... so i would investigate.

I am wiring a Honeywell wifi unit and I used a separate 24v transformer and connected to the c and rc terminal. My system is ac and heat and uses both and rc and rh wire. I wired the rc to the r ter


A thermostat is a switch. It connects 24vac from one terminal to another depending on the request. The 24vac comes from a transformer, usually located in the furnace and connects to the R terminal. Since you are using RH and RC without a jumper between it means there are two transformers, one in the furnace for heating (RH) and one in the air conditioner condenser used for cooling (RC).
Your old thermostat was probably mechanical and did not have a C (24vac common) terminal. Your new thermostat requires power to operate therefore needs a wire connected to a C terminal. I would get rid of the transformer you added and look for an unused wire in the bunch at the thermostat. If it's there connect it to C on the thermostat and to C on the furnace. Remove any jumper from R to RC or from RH to RC depending on your thermostat and connect wires same as the old thermostat.

I installed a new thermostat on my hvac system and the heat is not working anymore.


On that thermostat there is an R and an RC wire connection, the R is the power wire for heat and RC is the power wire for cooling. If you connected the power wire (normally red in color) to the RC only the fan control and AC control will work, there has to be a jumper wire between the R and RC terminals (assuming there is only one control transformer) for both the heat and cool functions to work.

Trying to replace my old t-stat to a Hunter 44260 t-stat, the old wirings are :Rc-Rh(jumpered), G,Y,W, O & B and the new t-stat has G,Rc,Rh,Y/O,W/B & Y1, i dont know where to connect the old wiring...


It sounds like a standard gas fired heating system and electric cooling. Leave the jumper between the RC and RH and attach the red wire.to one of them it does not matter since they are jumped. Attach green to G attach the white to W attach the yellow to Y if there is no C screw on the new thermostat leave the blue wire disconnected and not touching anything. It is the common and many systems use feedback to provide the common power. The O & B terminals are used for heat-pump systems only. Their purpose is for the reversing valve. Depending on the make or model either the O or B is used not both but remember the O & B are for heat-pumps only not gas fired furnaces. NOTE the best wiring practice is strip the wire with your thumb nail not wire strippers they tend to leave nicks in the wire and will break in the future also wrap the wire around the screw in a clockwise direction it will pull the wire into the connection tightly if you wrap the wire counterclockwise it will push the wire away from the connection. Good luck. I assume the new thermostat is digital. If it is not digital the heat anticipator must be set. If that is the case let me know and I'll give you instructions on how to set it.

I will assume you did not write down what color wire you took of each letter on old thermostat? Sometimes color of wire doesn't matter as some installers will use whatever color. If you noted where each wire was on old thermostat, just put same color wire to same letter on new one. Under normal situation. y is for compressor (cool) G, is for fan (on AC) , RC is 24 volts from transformer for AC side, RH is 24 volt transformer from heat/furnace, and W is for other wire from furnace, is furnace is only 2 wire system. Was there any wire connected to A on old thermostat?

I installed the RTH 230B thermostat, Theheat only works when set to the cool mode, I only have gas furnace(no ac unit). My old wires are Red, white, green and blue. What wires go where?


Hey jim Try....RH/RC jumper (connected with a small piece of wire)...RH/RC=RED...W=WHITE...G=GREEN blue=unused... should give heat only (in heat mode) no ac..tks

I want to replace programmable thermostat with old dial style


The terminals should be the same on both thermostats, except for C- common.
R- usually RED, goes to hot side of transformer,
W- usually WHITE, goes to heat
Y- usually YELLOW goes to outdoor unit
G- usually GREEN goes to furnace blower
Any of the other wires just cap them off you don't need them. If you have an Rh and Rc terminal instead of R and don't have them on the programmable then put a jumper from Rh ro Rc.
If you need more, then let me know what terminals you have on both t'stats and brand of furnace and AC, if you have a heatpump then there's more wires let me know.

Your house might be older.  Are your receptacles two-prong, or three?
I would ignore the missing "G" wire, and connect Red to both Rc and Rh, and Y to Y, and W to W.

If you have a forced air furnace with an air conditioner attached make sure you have a jumper wire between Rh and Rc. If the Bryant thermostat had a wire hooked up to C you do not want to hook this up to Rc. Just cap it off and put it back in the wall or disconnect that wire down in the furnace.
