SUBSIDIARY SP2 MODE:

SP2.B

 

Latch/sequence or non-linear cool.

Latch alarm LtCh

When activated, the alarm latches until manually reset, even though the alarm condition may have disappeared.

Sequence alarm hoLd

When hoLd is selected, in any alarm mode, it prevents an alarm signal on power-up. The alarm is enabled only after the process temperature has reached setpoint.

In level 1 select

SET.2

 

and then set the setpoint (SP2) value (y°).
