EPH Controls CRF2P-2_2201 Product information

  • Hello! I've analyzed the provided wiring diagram for the EPH Controls S Plan Wireless Pack. This document details the wiring connections for the R27-RF wireless programmer, motorised valves, RFR wireless room thermostats, and the wiring center. I understand the potential complexities of such systems, so feel free to ask me any questions about the components or wiring procedures.
  • What components are included in the S Plan Wireless Pack?
    Is it necessary to check the boiler installation instructions before wiring?
    What potential requirements might vary between boiler manufacturers?
