The thermostat is a switch when it reaches the desired temperature it closes or opens depending on waht is required. So you need no other wiring for it to work.

Most non-electronic thermostats work on three wires, excluding an earth which is uncommon anyway. The three wires are live from the timer/programmer, switched feed to valve/ boiler and neutral. The neutral wire is all too often ommited, but is used to give a return to the 'anticipator' which is a small heater which stabilises the switching cycle and reduces large temperature swings. If you only have two conductors, neither of them is a neutral and you can connect them either way round in the stat, but NOT to the Neutral terminal. The stat will not operate very accurately this way, and you would be better to replace it with a battery powered digital stat which will work properly on the two wires that you appear to have. Typically T6360 on this diagram-

Dont use the earth for a neutral, (as below) this could be very dangerous.

Hi. Read the advice that Jayktee has written. Some thermostats do not work without a neutral ( like a TP own brand ), this can be awkward if you only have twin and earth cable. Good luck and work safe. Do not use the earth for any other purpose but an earth!

If you have a hot water system, the thermostat switch normally turns on the central heating pump.
Use an ohm meter to check which terminals are connected when the thermostat is calling for heat and just connect across them

If you need a neutral and you dont have one use the earth it works just as well. then the other two wires go on the common terminal and the normally closed terminal. if you have air conditioning you will have a two stage thermostat and you will have three wires, a live input- a live output to the heating system and a live output to the cooling signal

Should be one cable containing several different colored wires in it. just hook them up the same way. If you have heat only then only 2 wires are usually used in the cable.

i would suggest contacting a electician. i have seen thermostats with both one and two wires. it depends on how old the house is

most stats dont require a Neutral.
It is just a switch so you will probably find the blue is the output back to your boiler/zone valve
