SP1L ( SP1 low limit value ) and SP1H ( SP1 high limit value ) in setup menu
are used to confine the adjustment range of SP1.
SP1L ( SP1 low limit value ) and SP1H ( SP1 high limit value ) in setup menu
are used to confine the adjustment range of SP1.
Example : A freezer is working in its normal temperature range -10 °C to -15 °C.
In order to avoid an abnormal set point, SP1L and SP1H are set with the
following values:
SP1L = -15 °C
SP1H = -10 °C
Now SP1 can only be adjusted within the range from -10 °C to -15 °C.
