    Hi,

    I am upgrading a NOBO RF heating system I have.

    As part of the upgrade, I have to replace a reciever unit that controls my water immersion heater.

    My existing installation is here:

    The water heater unit is in the middle marked "WH".

    My question is around wiring - it looks like a straight swap. The existing unit is wired as shown:

    https://sites.google.com/site/imagesforwebanc/_/rsrc/1330344346497/home/2012-02-27 11.37.45.jpg

    And the new unit needs to be wired as follows:

    Does it look like a straight swap job, or is there anything I need to know?

    Thanks,
    Alex
