Microgyr rwb20 replacement

Can I replace an old microgyr rwb20 timeswitch directly with a centaurplus c11 which I have been offered. On initial checks it appears not to be a direct replacement.

This is the old standard heating and hot water programmer . It has a standard back plate which can be left in place . Just undo the screws underneath the unit. Lift off . Then the new programmer will just fit straight back on . But you will need to find out which type of system you have . Fully Pumped or the old gravity hot water and pumped heating .
