    Yeah, I know. They are a pain in the butt. But they pay the bills to keep my server running. Just a fact of life, I am afraid.

    Want to get rid of them? Simple. Just become a Contributor level member or above and they will be gone. -> Please click HERE."

    Is that too much for me to ask of you to keep this site running? Well, sorry about that. I too wish I could get everything for free. But alas.....

    =====================


    Google Adsense ad revenue for December, 2025 was just $30 over the cost of the lease for the server running this site. So, in effect, the money providing the incentive for me to continue running this site is coming SOLELY from the paid memberships and sponsorships here. Which honestly ain't much....

Product description:
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. 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 heat tape, heat lamps, and ceramic heat emitters. It operates on 120 or 208/240 volts and its interchangeable sensor can be mounted up to 800 feet from the control unit.

KEY FEATURES:

* Reliable Electronic Accuracy
With a Liquid Crystal Display that clearly displays the current sensor temperature and other functions.

* Versatile Setpoint and Differential
Adjustments that allow user to quickly and easily configure the A419 to cut-in on temperature rise or drop in either the Cooling or Heating mode.

* Easy Fingertip-Touch Programming
That can be locked to deter unauthorized adjustments of the control.

* Light Emitting Diode
That indicates output relay status.

* Interchangeable Remote Sensor
That may be mounted up to 800 ft (244m) from the A419.

* Sensor Failure Indication
That alerts user to problems with the sensor circuit and operates the controlled equipment either on or off according to user selected mode.

* Compact, High Impact Plastic, NEMA 1 Enclosure
With captive cover screws, suitable for direct surface mount or standard DIN rail mount.

* Rated to 1500w
* 6.5ft Sensor

It will handle up to 1500 watts so you could run alot of them. Just depends on how many watts each enclosure uses. But, it only comes with one probe so you can only monitor one. So, all the enclosures would need to be the same and turned on at the same time. I run multiple enclosures and only have a 1-2 degree difference between all of them. One other thing you can do with this thermostat is add three probes and it will average the 4 probes to maintain temperature in 4 enclosures.
 
I can get them. I'll check with my supplier tomorrow for an exact price.
 
The probes are $25.00 a piece and are special order so it would take some time to get them in.
 
Q

does the unit make a audible clicking noise when it goes on and off and is the set point adjustable.thx,TWH
 
Yes, you can hear it when it turns on and off. The set point is adjustable.
 
i'll be running a oil filled electric heater both johnson and ranco are same price and same wattage,what do you suggest?
 
I prefer the Johnson myself. It is smaller and it can be set to shut off if the probe fails. The Ranco does not have this feature.
 
Always in stock and shipped within 24-48 hours.
 
Oil Filled heaters..

I have been using my Johnson Controls on 2 Oil heaters for 2 years now and they work great. I am also running a 220 AC unit on one and 3 racks on another.
 
I got mine from Dennis, I like it a bunch. Thanks Dennis for a great product!! :thumbsup:
