Please note: In ALL cases where a 24 hour model is stated as the recommended replacement its 7 day equivalent can be used and fitted in the same way.

NOTE: For the sake of clarity CentaurPlus models C21 and C27 have been shown
as recommended replacement models. However, where these are shown replacing
a common time base programmer, CentaurPlus models C121 and C127 could also
be used.
