• Set the output periods (control periods). Though a shorter period provides
better control performance, it is recommended that the control period be
set to 20 seconds or longer for a relay output to preserve the service life
of the relay. After the settings have been made in the initial setup, readjust
the control period, as required, by means such as trial operation.
• Set the control periods in the Control Period (Heating) and Control Period
(Cooling) parameters in the initial setting level. The default is 20 seconds.
• The Control Period (Cooling) parameter is used only for heating/cooling
control.
• When the control output is used as a current output or linear voltage out-
put, the Control Period settings cannot be used.
• The control period can be set for standard models only.
• Direct operation increases the manipulated variable whenever the pro-
cess value increases. Reverse operation decreases the manipulated vari-
able whenever the process value increases.
