Looking for some help on whether or not I can easily change my heating controls.
I have 3 controls presently (one for upstairs heating, one for downstairs heating and one for hot water) - something like this:

What I want to know is if I can easily swap out these 3 controls and replace with a single 3 channel unit, something like this: [broken link removed]
My problem is that one of the controls I have at the minute is faulty and I'd like something that has a boost / +1hr option.
Thanks
