My boiler installer is very reluctant to install the DT10RF optimiser in my new system and I cannot work out why . All he says is we have had problems and he really can't add any more.
There are no wires so i would have thought the actual installation was the same.
Does anyone have any clues ? Does the unit have problems with tuning or adjusment ? is it unreliable ? .Do you need a better skill set to install it. Can it be retro fitted ?
I would appreciate informed opinion.
Many thanks
Chris
