    Hi everyone,

    I’m seeking advice on wiring my Immermat Flash Timer switch in conjunction with my Grant Euroflame Condensing Boiler House 70-90. Specifically, I’m connecting it to a Google Nest Gen 3 Thermostat with a Heat Link.

    Wiring Details:

    • Immermat Flash Timer:
      • Brown (Live In)
      • Blue (Neutral In)
      • Live Out (Switched Live)
      • Neutral Out (Switched Neutral)
    • Google Nest Gen 3 Thermostat Heat Link:
      • L (Live)
      • N (Neutral)
      • 2 (Call-for-Heat)
      • 3 (Common)

    I am trying tk get heating to work but for somereason it does not switch on.

    When I reconnect the Immermat ot works perfectly. The images below the Immermat wiring
