Johnson Controls Thermostats
 

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:

Still have these.

question how many enclosures can you run on one of them ?

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.

do you carry these extra probes? if so what do they cost ? thanks

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?
