A28 Series Two-Stage Temperature
Controls With NEMA 1 Enclosure


These two-stage controls are
designed to cover a broad range
of general purpose operating

temperature control applications
in the refrigeration, air
conditioning and heating fields.

Two SPDT switches permit
independent control circuits.

Each switch may be wired for
“open high” or “close high”
action, as required, providing

automatic changeover on
heating-cooling or similar

Models are
available with close differential
on each switch. A jumper across
the “common” terminals is

supplied as a standard feature.
Models are available for fixed or
adjustable between stage

All Series A28 temperature
controls are designed for use
only as operating controls.

Where an operating control
failure would result in personal
injury and/or loss of property, it is

the responsibility of the installer
to add devices (safety, limit
controls) or systems (alarm,
supervisory systems)

that protect
against, or warn of, control

I called trying to find out what happened to the rest of my order and was surprised to hear a warm and kind voice willing to do whatever it takes to find answers and follow through with her promise. Amanda is an asset worth holding on to and a credit to your company. She was very professional, helpful and courteous while assisting me with my order. I would most definitely assign her an A+ in customer service."
