Description
–
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
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

Solid Product, Great Value
This is the best and simplest temperature controller to use with refrigerators and freezers, just plug and play to obtain any temperature needed. I use these controllers extensively for home-brewing beer, and achieve very accurate fermentation temperatures. It will turn any freezer into a refrigerator, which is very handy around the holidays. These will also control space heaters.
You have to provide your own electrical cord, or just splice into the existing appliance cord, and the wiring schematic is easy to follow.

Manufacture testing need upgrading
I had purchased the A419, and it worked as it should.
Then I bought another A419 and the sensor circuit was not working. The replacement did not work either as the output circuit did not work.
What can I say. One worked, two other did not.

Excellent product
As an HVAC professional I have used nearly 100 of this family of controls and have experienced only 2 failures in over 10 years of using these controls. Just be aware that the low voltage version of this control (gbh suffix) has a limited amperage rating on the contacts.. These were the 2 failures I had.....

Q: Does this product come with the associated male and female power chords, or just the temperature sensor?
Asked by 15 years ago

Verified Reply- PexSupply StaffThis is a hard-wired unit; it does not include a power cord.

I had to supply the power chord. I just used an existing 3 wire (must have ground) extension cord, cut in half. It comes with the temperature sensor.

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.

- Nate the Brewer
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.

Q: In the FAULT CODES solutions they tell you to CYCLE POWER TO RESET THE CONTROL. What does that mean?
Asked by clap 15 years ago

Verified Reply- PexSupply StaffIt means that you need to cut off power to the unit and then turn it back on.

Q: Will this thing run a furnace blower motor with out getting hot frying it? It moves 1300 cfm's don't know the horse power
Asked by 15 years ago
Add your answer
Verified Reply- PexSupply StaffThis control has a SPDT dry contact relay. It will not "fry" a motor provided the contact rating is not exceeded. Keep in mind that any electrical motor can be "fried" if it is wired incorrectly.

Verified Reply- PexSupply StaffAccording to the manufacturer, the total watts this thermostat can control is 1920 watts.

It's in the technical specifications, page 8 of the instructions. Power (Watts) is voltage (Volts) multiplied by current (Amps). If wired for 120VAC it's 696W If using the normally close contacts 1920W If using the normally open contacts
