The Sub-Zero Series SZ-7510-P-DI are aesthetically superior
versions of their predecessors. The SZ-7510-P-DI is a single
set point controller. with digital input. They are specifically
designed for refrigeration applications wherein the
compressor cuts off at set point and is restarted at a
temperature of set point plus differential.
Additionally these controllers offer several protection features
that are easily understood by the examples in the instructions
below. The controller can be used for heating applications,
when the P1 parameter is set to “1” .
A number of parameters are displayed alphanumerically to set
up the instrument for each specific application.
The SZ-7510-P-DI controller can be used for several
