After installation, I was disappointed & really wish that I had chosen to pay an extra £7 for the electronic version instead of chosing to replace my existing controller with (emergency corroded battery) with your latest model. It was not clear that it would have been possible to change to the electroniic model when I first ordered online. However it is now up & running reasonably overnight with preset shutoff time at 09:30am. Best wishes, Anthony Goodliffemartin (05.08.2016.)Slightly updated model than the one i replaced which is good thing ,works well why change something that works and has a proven track recordDudley Parry (17.07.2016.)Perfect replace rent for previous 13 year old unit.
