Johnson A419 - Digital On / Off Thermostat
Digital Electronic On/Off Thermostat
The Johnson Controls A419 electronic temperature control 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. An adjustable anti-short cycle timer prevents controlled equipment from
restarting immediately after shutdown.
