    Hi,

    Just swapped all my thermostats to DT90E's (6 in total) and wanted to know if I should change anything in the installer menus as per my setup. The old thermostats were 3 wire (Live, Sw-Live and Neutral) and the new ones I've wired up with just 2 wire (Live and Sw-Live).

    I have a Nibe Fighter 200P boiler which is currently on setting '2' due to the winter. There are 2 control boards (Nu-Heat Optiflow Wiring Center) one for upstairs and one for downstairs along with 2 manifolds, again one up and one down.

    UFH is in every room in the house and I have 3 thermostats upstairs (Bedroom1, Bedroom2 and Landing/Bathroom) and 3 downstairs (Living Room, Hall/Toliet and Kitchen).

    Any advice on setting up the thermostats in installer mode would be very helpful.

    Thank you.
