1. Wire the new controller as follows:

•If you are replacing an Analog Temperature Controller, P/Ns 28071-0012 or 28071-0018 (see Fig. 1A), refer to Figure 4A for a listing of the new terminal numbers.

•If you are replacing an Analog Temperature Controller P/N 34983 (Fig. 1B - PS200VL models only), refer to Figure 4B for a listing of the new terminal numbers.

•If you are replacing any Digital Temperature Controller, simply reconnect ALL of the original wires and jumpers to the same terminals, as all terminals are numbered the same.

EXCEPTION: Controller P/N 32571(Fig. 1E - used on early PS360EWB ovens only) uses Termi- nals 4 & 5 for the mA output to the amplifier board. The current controller uses Terminals 15 & 16 for these connections, as shown in Figure 5A.
