Setting Output Specifications Section 3-5
For example, when the process value (PV) is lower than the set point (SP)
in a heating control system, the manipulated variable increases according
to the difference between the PV and SP. Accordingly, reverse operation is
used in a heating control system. Direct operation is used in a cooling control
system, in which the operation is the opposite of a heating control system.
Direct/reverse operation is set in the Direct/Reverse Operation parameter
in the initial setting level. The default is or-r (reverse operation).
Operating Procedure In this example, the input type, temperature unit, direct/reverse operation, and
control period (heat) parameters are checked.
Input type = s (K thermocouple)
Temperature unit = c (°C)
Direct/reverse operation = or-r (reverse operation)
Control period (heat) = 20 (seconds)
Operation Level 1. Press the O Key for at least three seconds to move from the operation
level to the initial setting level.

time, s (K thermocouple) is set. To select a different sensor, press the U
or D Key.

3. Select the Temperature Unit parameter by pressing the M Key. The default
is c (°C). To select f (°F), press the U Key.
4. Select the Control Period (Heating) parameter by pressing the M Key.
The default is 20.
5. Select the Direct/Reverse Operation parameter by pressing the M Key.
The default is or-r (reverse operation). To select or-d (direct operation),
press the U Key.
Operation Level 6. To return to the operation level, press the O Key for at least one second.
