The A419 controls have heating and cooling modes, adjustable setpoint and differential, an adjustable anti-short cycle delay, and a temperature offset function. I think someone already mentioned a fan to help move the air around inside - I put one in mine and it seems to help. This equipment generates, uses, and can radiate radio frequency energy and, if, not installed and used in accordance with the, instruction manual, may cause harmful interference to, radio communications. Because Radwell is not an authorized distributor of RQAUS1 products, the Original Manufacturer's warranty may not apply. If you need a specific A419 firmware or series, then we probably have it. Power What I'd be doing is calibrating both in the same solution at the same time to be sure you actually have a variance, otherwise I'd assume you're seeing possible temperature swings from a more accurate/rapid measurement on one and not the other. pVp[)1QQsXP'[*f\`T+X0 +BY9'hppGGx}q[wpMoUMB-CG9 dnIHY];ObQ= b\SfsUvS_>OP]wp%}V#G If all these are in good condition, but the problem persists, try the following procedures to determine the cause of the problem. temperature and humidity controllers; t606msx-4 series; t606msx-4+pir series (23 pages), Well insertion temperature sensors (3 pages), Temperature and relative humidity wireless room sensors (14 pages), Manual will be automatically added to "My Manuals", Temperature Controller Johnson Controls A419 Series Product/Technical Bulletin, Temperature Controller Johnson Controls A419ABG-3C Installation Instructions Manual, Temperature Controller Johnson Controls W43A Quick Manual, Temperature Controller Johnson Controls A70 Series Installation Sheets Manual, Temperature Controller Johnson Controls TM-2161 Installation Instructions Manual, Temperature Controller Johnson Controls System 350T A350P Manual, Temperature Controller Johnson Controls System 350 A350A Technical Bulletin, Temperature Controller Johnson Controls TE730 Series Installation Instructions, Temperature Controller Johnson Controls T606MSP-4 Installation Instructions Manual, Temperature Controller Johnson Controls TE-631xM Installation Instructions, Temperature Controller Johnson Controls TE-6800 Series Installation Manual, Temperature Controller Johnson Controls FX-WRZ Series Installation Instructions Manual, Temperature Controller Johnson Controls TE-6800 Series Installation Instructions Manual. barometric pressure and cross ambient problems.

NEMA 1 mounting hole pattern is identical to that of the system 350 controls and models of the A19 control. I want my chest freezer set to 40. IOW, don't focus on the air temperature, as it will swing a lot and all you are doing is spot checking the temp and that won't tell you much as it won't be the actual temp of the fermenting wort. The liquid temp will be more consistent than the temp of the air. hbbd``b`f ,k' s@ N$d)-LL !` 6L & External range adjustment may be by screwdriver slot, Temperature controls - single-pole, single-throw and single-pole, double-throw models with nema 1 enclosure (3 pages), Series a19a/a19b/a19d thermostats for refrigeration, cooling, heating, ventilation and air-conditioning (10 pages), Single and two-stage space thermostats for farm and general purpose applications (4 pages), Touch screen fan coil thermostat (5 pages), Lcd digital fan coil thermostat (4 pages), Line voltage fan coil unit thermostat (5 pages), Fcp non-programmable and programmable fan coil or ptac thermostat largo (28 pages), Manual will be automatically added to "My Manuals", Control Unit Johnson Controls A19 Series Installation Sheets Manual, Thermostat Johnson Controls A19A Product Bulletin, Thermostat Johnson Controls A19BAC Installation Instructions, Thermostat Johnson Controls A19BAC Installation Sheets Manual, Thermostat Johnson Controls METASYS TEC1100 Series Technical Bulletin, Thermostat Johnson Controls Hx 3 S1-THXU430W Installation Manual, Thermostat Johnson Controls T8000 Series Installation Instructions, Thermostat Johnson Controls T8000 Series Quick Start Manual, Thermostat Johnson Controls TEC2001-4 Installation Instructions Manual, Thermostat Johnson Controls TEC2216-4 Installation Instructions Manual, Thermostat Johnson Controls T5000 Installation Instructions, Thermostat Johnson Controls T7200 Installation Manual, Thermostat Johnson Controls T7000 Series Installation Instructions Manual, Thermostat Johnson Controls T2000 Series Manual, Thermostat Johnson Controls FCP-NA-701-L User Manual, Thermostat Johnson Controls T701DFP-1 Owner's Manual.

Space and return air temperature control. One problem with the chest feezers if you do not have a fan installed, is that there can be a huge difference between the air temp near the top vs near the bottom. I've been using the Johnson Controls A419 Electronic Temperature Control for my chest freezer kegerator. I would tend to agree with the 2 being a bit close for an upright fridge/freezer, but a chest freezer (especially with the added thermal mass of the kegs) is fairly stable. or. Johnson Controls - A419 - Electric Temperature Controls With Plugs! Using an ohmmeter, measure the resistance across the two sensor leads while the sensor is at the temperature taken as before step. 657 0 obj <> endobj 1. I am using the A419 with a fridge. Tested. The control provides remote sensing capability, and electronic accuracy in a Type NEMA 1 high-impact plastic enclosure suitable Cooling tower pump and fan control. And, verify between the two 24V terminals on low voltage models. Special close differential models available. Looking for recommendations on which Johnson Control unit would work best to keep ale temps: the $53 Johnson Controls A19AAT-2C Freezer Temperature Controller. Refer to the manual to verify that the measured temperature and resistance matched with established temperature and resistance values. Even opening the lid periodically doesn't affect the temperature too much. Figure 1: A419 Temperature Control with NEMA 1, Displays the sensed temperature and control-function status clearly; custom icons on the display indicate the control and system status at a glance, Allows the user to set a precise (1F or C) temperature differential from 1 to 30F or C; providing a much tighter differential than electromechanical controls, 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, Allows the user to shift the cut-in and cutout setpoints by an adjustable offset based on the status of a user-installed, external switch, such as a time clock, NEMA 4X Watertight, Corrosion-Resistant Enclosures, Increase application options, allowing surface and snap-fit DIN rail mount, or Watertight surface mount, 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, Provide options for most refrigeration and HVAC control-voltage applications. 0 Yes, I just have the Johnson probe dangling in the keezer.
