Red
Red is negavite some black
There are two types of thermostats. One is line voltage and will require a splice be made in the old thermostat junction box . From the old box a new cable has to be pulled to the new thermostat junction box. This wire must be of the same size as the existing wire.The other type of thermostat is low voltage thermostat. This uses usually # 22 size wire and because it operates on low voltage it does not need a junction box to make a splice in. Solder and tape the new wire on to the old piece and then take it to where the new thermostat is to be located.
In Bangladesh the color of live is green and neutral is blue and ground is black.
The color of the load wire is kind of orange but it is tiger orange.I think it is gray.
Dont connect the common wire.

Thermostat wiring can be hooked up by following the colors of the wires. Each thermostat comes with color coded wires that are the same colors as the thermostat already in place in the home. Hook each wire to its colored wire.
Use what is called bell wire or thermostat wire.
1st thing to do is turn off power to unit. if you dont do this you risk of burning up the transformer.. all thermostat wires are color coded. if you can pull the old thermostat off and match them to the new thermostat it shouldnt be a problem hopefully the tecnician who installed the unit hooked it up right but the color code should be this- R is RED that is your power wire 24v Y is YELLOW that is your cooling wire W is WHITE that is for your heat G is GREEN that is your operating the fan Those 4 are for straight heat and cool.. if you have a heat pump there will be an aditional wires which is- O is ORANGE wire that is for the reversing vavle some units also have a common wire and that is the BLUE wire.. That would be attached to the C terminal on a stat..
green <<>> In North America the common (neutral) conductor is white. The ground wire is green or bare depending on its location in the system.
That Thermostat is LOW voltage. IT does not have a ground wire. There is no need for a ground. it only opperates on 24 volts. there may be a green wire but it does not mean it is a ground
Do not do this.
your water temp. sensor is unhooked or the wire is broken (common) it's a "t" shaped 2 wire plug on the thermostat housing
Depends on what you are wiring. Green is a common color used for ground. Sometimes it is just a bare copper wire.
No, example- If the wire is blue with a white strip, (which is your remote wire for the amp turn-on) the wire is blue, the strip is not the color.
If your thermostat is designed to switch the fan on and off at say 120 volts, then it acts just like a switch. This means that you insert the two wires from the thermostat in series with the black wire going to the fan. So let's say you have a supply of power for fan that has black, white and bare wire ground. You connect the white to white on fan and ground to ground. You then connect one wire of the thermostat switch to supply black and one to fan black wire. If you are unsure of the type of thermostat or anything else get an electrician. This is just one possible solution given the information provided.
