Refined title: Dual Probe Digital Temperature Controller for Reptile Terrariums

1. Temperature Control with Pymeter: Pymeter controls temperature through its Temperature Controller, which functions as both a Heating and Cooling controller. To activate Heating or Cooling, you must set the ON-Temperature (ON-Temp) and OFF-Temperature (OFF-Temp) thresholds accordingly. Heating initiates when the temperature falls below the ON-Temp and stops when it exceeds the OFF-Temp. Therefore, for effective heating, the ON-Temp (1oN, 2oN) should be lower than the OFF-Temp (1oF, 2oF). During heating, 1oN (2oN) represents the minimum allowable temperature, while 1oF (2oF) denotes the maximum allowable temperature. Conversely, Cooling begins when the temperature rises above the ON-Temp and ceases when it drops below the OFF-Temp. For cooling operations, the ON-Temp (1oN, 2oN) should be higher than the OFF-Temp (1oF, 2oF). In cooling mode, 1oN (2oN) is the maximum allowable temperature, and 1oF (2oF) is the minimum allowable temperature.

2. Temperature Reading Accuracy: Each Pymeter controller undergoes calibration before leaving the factory, ensuring precise temperature readings. It is essential not to compare its accuracy with common, less accurate thermostats, thermometers, or temperature guns. If there are concerns regarding the accuracy of the Pymeter controller, a calibration can be performed using an ice-water mixture (which stabilizes at 32°F during melting). This comparison will clarify the accuracy of the Pymeter against other devices.

3. Continuous Beeper Sound: The continuous beeping may be due to incorrect Alarm settings (AL, AH, d7) that do not correspond to your desired temperature thresholds. AL denotes the low-temperature alarm (activated when the current temperature equals or falls below AL), while AH indicates the high-temperature alarm (activated when the current temperature equals or exceeds AH). The d7 setting triggers an alarm when the temperature deviation between Sensor 1 and Sensor 2 exceeds d7. If these alarms are unnecessary, it is advisable to retain the default values, which typically avoid triggering alarms. To reset to factory settings, switch the temperature unit from Fahrenheit to Celsius in the settings menu. For more detailed instructions, refer to the User Manual PDF available in the Product Information section.

4. Additional Features of Pymeter:

5. Customizable Outlet Control: Each outlet, whether connected to a heater or fan, can be programmed to activate at a specific temperature and deactivate at another.
6. Dual Controllers: Incorporating two separate outlets, each supporting both heating and cooling functions. This setup is enhanced by two waterproof sensors, allowing different temperature settings to control distinct areas. For instance, it accommodates configurations like two heat lamps or mats for two separate zones or tanks.
7. Safety and Reliability: Equipped with high and low-temperature alarms, as well as a temperature difference alarm, ensuring the security of your temperature targets.
8. Convert Freezer to Refrigerator: Includes a Power-On delay feature to protect compressors from frequent cycling, facilitating conversion from freezer to refrigerator functionality.
9. Wide Application: Versatile use as a temperature switch or thermostatically controlled outlet for various applications such as reptile terrariums, aquariums, greenhouses, grow tents, garage fans, and heating pads, among others, catering to needs in breeding, seedling growth, and fermentation processes.
