If you are looking for a coding number for your heat pump, the first port of call should always be the product data badge. Example here is an SI75TU heat pump, which has the coding 4017.
If your data badge does not have a code listed, below is a table of heat pump model numbers and the coding number required when using L software or higher on a WPM controller.
You may also find the article "I have Fault code F15 / Sensors fault on my heat pump (WPM or Touch screen based). What does this mean?" useful if you are experiencing coding number issues on the heat pump.
