    Hello,

    I would like some advice, I have purchased a Hive 2 system to replace my Danfoss TP900. When I have taken off the timer to look at the wiring it doesn't match up to what I was expecting.

    The Hive 2 with HW wiring seems to suggest that terminals 1 & 2 be connected but on the TP9000 they are not present and there are also wires in terminals 5-6 for the remote sensor? Any advice would be great. I have added photos to illustrate.

    1&2 are not used on all systems, you do not need to connect anything to them.
    Earth,N,L,3,4 connect to the same terminals on the new Hive.
    The remote sensor is specific to the Danfoss and is of no use with the new Hive, the sensor and the wires to it should be removed.
    You will also need to connect the two brown wires at the right side together with a separate terminal block.

    Thanks falmeport,

    Why in the instruction manual does it say connection 1 & 2 should have the hot water and heat off wires going into it? From what you are saying is that the sensor wires should just sealed up and the others wires should be the same.

    Sorry for another question!
