An on-line multiple zone oven is used to dry paint. Since heat demand is
various at different position in the production line, multiple zones with
individual controls should be used to ensure a consistent temperature profile.
If you order a BTC-2500 with a retransmission unit for the master controller,
and retransmit its set point to the input 2 of the rest of slave controllers, each
zone will be synchronized with the same temperature. Here is an example:
