Do I have a Master Valve?
If there is a wire connected to the MV (Master Valve) terminal of your
controller then there is a master valve in your system. The diagram below
shows how this would look in the ESP-ME3.
NOTE
2-Wire controllers (e.g. ESP-LXIVM) use decoders and may not feature a MV terminal.
