NOTE: Programmers The CentaurPlus, ChannelPlus and 425 Series models detailed
within the Programmer table do not have any SPARE or LINKING terminals. If spare
terminals have been used on the programmer being replaced then any connected
wires should be removed and re-connected into a separate piece of terminal block.

Timeswitches Terminal 1 on the CentaurPlus and Terminals 1,2 & 3 on the ChannelPlus
and 425 Coronet models detailed within the Timeswitch table are SPARE or LINKING
terminals. In the event that the number of spare terminals used on the timeswitch
being replaced exceeds those detailed above then any connected wires should be
removed and re-connected into a separate piece of terminal block.
Wires from different spare terminals should not be joined together.
