Combines keypad programming with
a liquid crystal display (LCD) to provide greater built-in control versatility.
A large display screen lets users check between setpoint and temperature at
a glance, and a bright LED also makes it easy to see relay status. Even with
these convenient features, the A419 is the most compact electronic temperature
control currently available. The A419 features a single-stage temperature control
with a single-pole, double-throw (SPDT) output relay, which makes it ideal for
use with refrigeration and HVAC equipment, including frozen and refrigerated
food cases, beverage coolers, and pump and boiler applications. It operates
on 120 or 208/240 volts and its interchangeable sensor can be mounted up to
800 feet from the control unit. An adjustable anti-short cycle timer prevents
controlled equipment from restarting immediately after shutdown.
