A319 Series
Electronic Temperature Control
Code No. LIT-1927100
Issued February 1, 2009
Description
The A319 Series is a line voltage single-stage
electronic temperature control with single-
pole, double-throw relay output and LED
indication. The A319 is designed with heating
or cooling modes of operation, adjustable
differential, and an interchangeable
temperature sensor. The A319 couples
electronic accuracy with remote sensing
capability in a NEMA 1 high-impact plastic
enclosure suitable for surface or DIN rail
mounting.
Features
• operates on 120 or 208/240 volts, which
eliminates need for a separate
transformer, saving installation time and
cost
• electronic circuitry improves accuracy and
provides higher reliability than equivalent
electromechanical controls
• solid-state sensor handles remote sensing
applications without the need for ambient
compensation or other limitations of
electromechanical temperature controls
• interchangeable temperature sensors and
mounting accessories allow flexibility in
application, increasing versatility and
serviceability
• two models cover temperature ranges from
-20 to 220°F (-30 to 105°C), reducing
inventory by encompassing the
temperature ranges required to support the
majority of refrigeration and HVAC
applications
• wide adjustable differential of 1 to 30°F
(0.5 to 17°C) enables the user to match
equipment cycle rate for a given
application; maintains a tighter differential
than typical electro-mechanical controls
• field-selectable mode jumpers work to
control either heating or cooling equipment
with LED indication of relay energization
status
Applications
The A319 can be used to control a wide variety
of single-stage refrigeration or HVAC
equipment. Typical applications include:
• frozen/refrigerated food cases
• compressor lockout
• beverage/milk coolers
• condenser fan cycling
• boiler control
• pump control (cooling towers)
• space and return-air temperature control
• immersion sensing for actuation of hot
water and steam valves in heating
applications
