appropriate zone assignments whenever a set point is to be sent to the temperature controller. The
temperature set point is sent to every instrument number in the temperature zone assignment.
If the ZONE_OFF (Zone Offset) opcode had been used in the program, the set point sent to the specified
zone instrument would have the offset added. For example, a 3-zone pit furnace, where the bottom zone
usually has a higher set point. The middle zone and the top zone usually have a lower set point. The bottom
zone temperature controller is assigned to zone 1, the middle temperature controllers to zone 2, and the
top zone controller to zone 3.
If the first three steps of a program are as shown below, then the bottom zone set point is 1775, the middle
zone is 1750, and the top zone is 1800.
Step Opcode Temperature Option
1 ZONE_OFF 25 Zone 1
2 ZONE_OFF 50 Zone 3
3 SETPT 1750
The first step sets the offset for zone 1 to 25 degrees; therefore, the bottom zone controller would be sent a
set point of 1775 when step 3 is executed. Likewise step 2 sets the offset for zone 3 to 50 degrees. The top
zone then receives a set point of 1800. The middle zone controller would receive the 1750. The temperature
controller displayed on the Status Display is instrument #2. If instrument #2 were the top zone controller
then the Status Display would show the 1800-degree set point.
When using the multi-zone offset feature, the temperature controller assigned as instruments 1 and 2
should be in zones that will not be offset.
