CONTROL MODE SELECTION
ON/OFF Action
Switch 1 of the function selector DIP switch is factory-set to OFF,
so the temperature controller performs ON/OFF control
action.Set switch 3 to ON when the temperature controller is
used to control a cooling device such as a chiller or freezer.

PID Action
Set switch 1 of the function selector DIP switch to ON to perform
PID control action. Follow the steps described below
Determining Proportional Period
Set switch 2 of the function selector DIP switch to OFF to select a
proportional period of 20 seconds. This is used when the PID
control action is performed with the contact output of the
temperature controller, or when using an external relay or
contactor.

When a quick response in required, set switch 2 to ON to select a
proportional period of 2 seconds. Even when a solid state relay
(SSR) is used, set the 2-second proportional period only when
quick response is essential. Avoid using this setting with a
contact output because it will shorten the relay’s service life.
