Determining Proportional Period
Set switch 2 of the function selector DIP switch to OFF to select a

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.
