• These parameters set the output periods. Set the control periods taking
the control characteristics and the electrical durability of the relay into
consideration.
• For standard control, use the “control period (heating)” parameter. The
“control period (cooling)” parameter cannot be used.
• Whenever the heating control output is a current output, the “control
period (heating)” parameter cannot be used.
• For heating/cooling control, the control period can be set independently
for heating and cooling. The “control period (heating)” parameter is used
for the heating control output, and the “control period (cooling)” parameter
is used for the cooling control output.

• “Direct operation” refers to control where the manipulated variable is
increased when the process value increases. Alternatively, “reverse oper-
ation” refers to control where the manipulated variable is increased when
the process value decreases.
• Select one of the following three alarm 1 types:
Deviation, Deviation range, or Absolute value

Control Period (Heating) The cooling control output and heat-
ing control output must be assigned
to relay/voltage outputs.
The control must be set to 2-PID
control.
For the “control period (cooling)”
parameter, the control must be set to
heating/cooling control.
