eniacs Posted November 2, 2023 Share Posted November 2, 2023 Can anyone help with a photo of their FTC6 DIP switch settings please? I cannot get mine to work with the outdoor unit, unless i have Sw4-1 and 2 on. Which seems like its making it think there is an outdoor unit, even though it isnt communicating. Once those 2 switches are set, FTC6 appears happy, switches the pump and valve, but the heat pump never actually starts! A frustrating unit. It is possible ive missed somthing or even that the outdoor unit is faulty... But im hoping its a setting. Link to comment Share on other sites More sharing options...
PhilT Posted November 3, 2023 Share Posted November 3, 2023 I cannot get a clear enough photo but I can see on mine the following are ON: SW1 - 2, 3, 7, 8 SW2 - 8 SW3 - 5 SW5 - 2 Link to comment Share on other sites More sharing options...
eniacs Posted November 3, 2023 Author Share Posted November 3, 2023 Thanks so much. Figured out the problem is I've switched off SW2-8 as i dont have a flow sensor. This means that the unit is looking for a non R32 HP and so it failed on no comms! Mitsubishi were pretty helpful with this Link to comment Share on other sites More sharing options...
