EPH Four Channel Digital Programmer R47 V2

The EPH Four Channel Digital Programmer (R47 V2) is a versatile 4-zone programmer with 24-hour and 7-day operating modes, ideal for controlling multiple zones in a central heating system. The R47 V2 is the latest version and is designed as a direct replacement for the original R47, using the same backplate for straightforward upgrades without rewiring.
