1. Производ је готовview
The Johnson Controls A19 Series Thermostat (Model A19AAT-2C) is a robust and compact temperature control device specifically engineered for temporary cooling installations. It features a Single-Pole, Single-Throw (SPST) switch that opens on a temperature drop, making it ideal for applications requiring precise temperature management outside the range of standard on-board thermostats.
Кључне карактеристике:
- Сингле-сtage cooling controls with SPST switches that open on temperature drop.
- Designed to override on-board refrigerator thermostats for accurate temperature control.
- Adjustable 20 to 80°F (-7 to 27°C) set point range with a fixed differential.
- Enclosed in a rugged steel NEMA 1 enclosure for durability.
- Includes a 6-foot extension cord with a piggyback style plug.
- Equipped with a remote sensing bulb and a 6 ft (1.8 m) capillary tube.

3. Упутства за подешавање
3.1. Одабир локације
Choose a location for the thermostat control unit that is easily accessible and where the ambient temperature does not interfere with the sensing bulb's operation. Ensure the location is dry and protected from direct sunlight or extreme temperatures.
3.2. Sensing Bulb Placement
The remote sensing bulb is critical for accurate temperature measurement. Place the bulb in the area where temperature control is desired (e.g., inside a refrigerator or cooling chamber). Ensure the bulb is not in direct contact with cooling coils or heat sources, which could lead to inaccurate readings. The 6 ft (1.8 m) capillary tube allows for flexible placement.
3.3. Електрични прикључак
The thermostat comes with a 6-foot extension cord and a piggyback style plug. Plug the thermostat's cord into a standard 120V AC outlet. Then, plug the appliance you wish to control (e.g., a portable cooling unit or refrigerator) into the piggyback receptacle on the thermostat's plug.
Warning: Ensure the appliance's power requirements do not exceed the thermostat's electrical ratings. Consult the appliance's manual for its power consumption.
4. Упутство за употребу
4.1. Подешавање температуре
The A19AAT-2C thermostat features an adjustable dial for setting the desired temperature. The range is from 20°F to 80°F (-7°C to 27°C). Rotate the dial to the desired set point. The thermostat will activate the connected cooling appliance when the temperature rises above the set point and deactivate it when the temperature drops below the set point, maintaining the desired range.
4.2. Switch Action
This thermostat utilizes a Single-Pole, Single-Throw (SPST) switch that opens on temperature drop. This means that when the temperature in the sensed area falls below the set point, the electrical circuit to the connected appliance is interrupted, turning off the cooling unit. When the temperature rises above the set point, the circuit closes, and the cooling unit turns on.
5. Одржавање
5.1. Чишћење
Periodically wipe the exterior of the thermostat control unit with a soft, dry cloth to remove dust and debris. Do not use abrasive cleaners or immerse the unit in water.
5.2. Инспекција
Regularly inspect the power cord, plug, and capillary tube for any signs of damage, such as fraying, cuts, or kinks. Ensure the sensing bulb remains securely in its intended location. If any damage is observed, discontinue use and contact a qualified technician for repair or replacement.
