Description for Johnson Controls A419ABC-1C

The A419 series controls are single-stage, electronic temperature controls with a Single-Pole, Double-Throw (SPDT) output relay. They feature a lockable front-panel touchpad for setup and adjustment, and a Liquid Crystal Display (LCD) for viewing the temperature and status of other functions. A Light-Emitting Diode (LED) indicates the control output relay On/Off status. The A419 controls are available in 24 VAC or 120/240 VAC powered models. The A419 controls have heating and cooling modes, adjustable setpoint and differential, an adjustable anti-short cycle delay, and a temperature offset function. The setpoint range is -30 to 212°F (-34 to 100°C). The controls feature remote sensing capability and interchangeable sensors. The A419 controls are available in either NEMA 1, high-impact plastic enclosure suitable for surface or DIN rail mounting or NEMA 4X watertight, corrosion-resistant surface-mount enclosures.

Features

  • Easy to Read Front Panel LCD:Displays the sensed temperature and control function status clearly, custom icons on the display indicate the control and system status at a glance
  • Wide Temperature Differential Adjustment Range (1 to 30F or C): allows the user to set a precise (1F or 1C) Temp differential from 1 to 30 (F or C) providing a much tighter differential than electromechanical controls
  • Adjustable anti-short cycle delay (0 to 12 minutes in 1 minute increments): Ensures that the output relay remains off for a user set time delay, which helps avoid hard starts, nuisance overload outages, and unnecessary equipment wear
  • Switch Activated Temperature Offset Function: Allows the user to shift the cut in and cutout setpoints by and adjustable offset based on the status of a user installed, external switch, such as a time clock.
  • High impact, Thermoplastic NEMA 1 or NEMA 4X Watertight, Corrosion-resistant enclosures: Increase application options, allowing surface and snap fit DIN rail mount, or Watertight surface mount
  • Lockable Front Panel Touchpad: Allows easy set up and adjustment of the A419 control setpoint, differential, and other functions, a concealed jumper locks the touchpad, and deters unauthorized adjustment of the control settings
  • Low and Line Voltage Models: Provide options for most refrigeration and HVAC control voltage applications

This is my second purchase of this type item the first one has worked flawlessly for three years this one will be used on a similar system where the control turns on a circulator pump once the water in a tank has been heated to a set point. The directions are a little diffucult to understand if you are not familiar with terminology but overall heplful

      A:

      No you can't hook up two probes. And if you want to switch from a heating
      cycle to a cooling cycle i believe you need to move some jumpers on the
      circuit board.

      A:

      I believe you can only use 1 sensor however there is an input that you can connect to introduce a programmable offset in temperature. The controller has a programmable "set point" temp, Differential temp range setting, and a heat/cool mode

    Q:

    Was hoping to learn if the remote sensor is water compatible and up to what temperature can it handle? The application I'm looking to use it for is to control a hot water bath that I'd like to maintain at 40C or 104F. Can the sensor go directly into the water at this temperature?
    Thanks

      A:

      the probe itself can work up to 212 F and is ~2" long before attachment to
      the cable. it appears sealed by crimp and possibly silicone? i have briefly
      submerged the cable in water but not sure about doing this long term.
      if 2" is too short you can attach another style A99 sensor based on this
      quote in the manual:
      "Each A419 control includes a Johnson Controls/PENN
      A99 temperature sensor. The sensor may be removed
      and replaced with any compatible Johnson ControlsR
      A99 temperature sensor, or the wire leads on the
      sensor may be extended."
      these sensors are listed in this document:

      A liquid application will require a dry well. I use mine in glycol solution freezer. Made a dry well with a piece of copper pipe. Works great. I'm sure the temp stats are in the item descrip.

    • VERIFIED BUYER

      A:

      I don't believe it can be directly immersed. The sensor is a stainless steel probe approximately 2" (50mm) long that is crimped onto the carrier cable leaving some gaps that would allow liquid to enter. There may be other sensors in the Johnson Controls A99 ( www.johnsoncontrols.com<http://www.johnsoncontrols.com> )line that are directly waterproof, or there is an option for an immersed well for mounting the sensor in liquid applications (P/N WEL11A-601C).

      A:

      The A419 is rated for up to 212 deg F but the probe is not designed for
      direct liquid contact. You would need to use a thermowell of some sort that
      would work for your application.

      I don't believe it is intended for that type of load. Mine actuates relay that handles the direct load (5hp freezer compressor). A similar scheme should work for you.

      I don't think so. I don't have the specifications handy so... I switched my
      small solar pumps on and off with these units but even then used a relay
      rated for them to do it. Buy a relay big enough to handle the high load and
      I would say yes.

      I am going to say “YES”....as the controller is supposed to function with 120v or 240v units. I would question Johnson Controls if you have any particular reservations. Hope that helps! 5500w should make for a pretty quick HLT. Cheers!

      A:

      Simply cut a tee into the pipe and add a nipple long enough to house the probe.  The turbulence around the probe will provide an accurate temperature indication.

      A:

      I don't have the exact measurement handy, but he sensor on the Johnson
      controller is only about 1-1.25" long.
      In my case, I have it in a much smaller pipe (1/2" NPT Stainless). What I
      did is found a thermowell that was 1.5" deep and had 1/2" NPT threads. I
      insatlled a tee in the line I wanted to monitor and screwed the themowell
      into the tee perpendicular to the flow of the liquid.
      Hope this helps.

      Don't know if the helps, but the senro that came with my controller is only about 2 inches long. I have well that would surely fit into 2" PVC. Would you be able to place a tee and cap in the PVC and place the tempurature probe in the cap?? That's what I see as an option. Hope it helps.

    Does Johnson make this exact box that comes with two boxes into one? Meaning all the same specs as the A419 but two of them side to side or top to bottom all in one housing? Also with two seperate thermo sensors independently.

      It comes with only the sensor. You have to buy a three wire power cord ($8 at Lowe's for 6ft), and splice it in. I found exact directins on the internet for this very problem.

      No power cords are included, just the sensor cable. Go to Home Depot or Lowe's and purchase a 3-6ft extension cord (3 prong) and a 1/2" knockout wire clamp. The install is pretty easy, just be sure you understand the wiring diagram for the 120V installation.

      Just the temperature sensor. Wiring is easy. I used a Contractor grade 15ft,14AWG extension cord (15 A rated). I cut it in half and wired it up with the female end going to the kegerator and the male end going to the outlet. The extension cord is better than the actual cord coming out of the kegerator.
