Initial Setting Level Section 5-7
• 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.
• When 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.
cp Control Period (Heating)
The cooling control output and heat-
ing control output must be assigned
to relay or voltage outputs (for driving
SSR).
The control must be set to 2-PID
control.
For the Control Period (Cooling)
parameter, the control must be set to
heating/cooling control.
