Netatmo Smart thermostat

[johnpen]

Hi,

I've purchased a Netatmo wireless thermostat to replace satchwell tlx 2259.

I've looked at the install guide from Netatmo, and it says I need to identify the control wires: http://www.cube.com.mk/upatstvo/manual1_en-US.pdf

If there are only two wires, they are the control wires and are useful in this setup.
- If there are more than two wires, identify the two control wires. They are usually black or grey.
The wires can be identified as shown on the following diagram
Note: if there are more than two wires, the others are power supply wires and are useless here. They are usually brown, blue, green or yellow.

My thermostat has three wires and I cant easily identify the oones I need, can anyone help.

Terminal 3 of the TLX 2259 is live; terminal 1 is switched live. These are the control wires

The wire connected to terminal 4 is a Neutral, which is not needed. Make it safe by connecting to a small terminal block hidden behind the new stat.

Thanks, so to confirm from the picture of the existing thermostat I need the yellow and grey wire, it's not very clear which terminal is which.

The image has been rotaed for some reason, the wires are along the bottom.

No! you need the yellow and orange wires. The grey (blue?) wire is the neutral which needs to be made safe.
