A differential temperature controller in a boiler system works by comparing the current temperature to a desired setpoint temperature, applying a user-adjustable differential, and adjusting the heat input to the boiler to keep the temperature within the specified range. This control system helps ensure efficient and safe boiler operation. Here’s how it works:Sensing: The controller typically uses two temperature sensors, one to measure the current temperature of the water or steam inside the boiler and another to measure the desired setpoint temperature. These sensors are strategically placed in the boiler system.Comparison: The controller continuously compares the actual temperature (measured by the first sensor) with the desired setpoint temperature (measured by the second sensor).Differential Adjustment: The “differential” in a differential temperature controller refers to the temperature difference (or range) between the setpoint and the current temperature. This differential is often adjustable, allowing for fine-tuning of the control system. For example, if the setpoint temperature is 180°F, and the differential is set to 10°F, the controller will aim to keep the boiler’s temperature between 175°F and 185°F.Control Action: Based on the temperature comparison and the set differential, the controller takes appropriate control actions to maintain the desired temperature range. It does this by regulating the heat source, such as a burner or electric heating element, to either increase or decrease the heat input into the boiler.If the current temperature falls below the lower limit of the temperature range (e.g., 175°F in our example), the controller will increase the heat input by turning on the burner or increasing its intensity.If the current temperature rises above the upper limit of the range (e.g., 185°F in our example), the controller will reduce or turn off the heat source.Feedback : The controller continuously monitors and record Maximum and minimum temperature and in different seasons you can compare and adjusts differential ranges for more efficiency.Safety Features: The controller has safety features, such as high-temperature alarm function, which can shut down the heating process if the temperature exceeds a critical level to prevent overheating and potential damage.Not only does the Mini Temperature Controller Thermostat help protect against overheating or freezing, the buzzer and flasher alerts also notify you when the alarm is triggered, while the ability to turn off the outputs gives you even more control over your system.It also records maximum and minimum temperatures for two sensors, improving the efficiency of your system. The large and clear LCD display makes it easy to read the temperature, and with its mini and light design, it won’t take up too much space.Equipped with a timer delay for two zones and protect your equipment from damage due to frequent start-ups. Configurable between Fahrenheit or Celsius and equipped with temperature calibration for two sensors, this accurate controller has 0.1 C or 0.1 F resolution controlling. It even comes with a wiring diagram for easy installation.Don’t settle for a subpar temperature controller – upgrade to our Mini Temperature Controller Thermostat today and take the first step towards a more efficient, customized boiler system.Features:· Three differential modes (heating, cooling, and reverse outputs) and one two-zone mode.· Ability to set high/low alarm limits for 2 zones to protect against overheating or freezing, with buzzer and flasher alerts, and the ability to turn off the outputs.· Record maximum and minimum temperatures for 2 sensors to improve the efficiency of your system.· 2 timer outputs delay for Output 1 and Output 2 to protect your equipment from damage due to frequent start-ups.· Memory and factory default setting option.· Mini and lightweight design with a 2-color display (red and blue) for each zone.· Configurable between Fahrenheit or Celsius.· Large and clear LCD display.· Temperature Range -58 ~ 248 °F (-55 ~ 120 °C).· Equipped with 2 outputs (one for controlling differential value and another for controlling heating system).· Control temperature by setting the temperature set value and the differential value.· Temperature calibration for 2 sensors.· Accurate controller with 0.1°C or 0.1°F resolution controlling.· Equipped with 2 sensors for controlling differential between 2 zones.· Wiring diagram for installation included.Temperature Controller Specifications:· Temperature Measuring Range: -58 ~ 248 °F (-55 ~ 120 °C).· Controlling Resolution: 0.1 degree.· Relay contact capacity (Heating or cooling): 10 Amp for 110-240V.· Storage Temperature: -30 ~ 75 °C.· Operating Relative Humidity: 20 ~ 85% (No condensation).· Power Supply: 100-240 V AC.· Power consumption: < 3 W.· Equipped with 2 waterproof sensors.· Item dimensions: approximately 75 (W) x 86 (H) x 35 (D) mm (2.95’ x 3.39’ x 1.38’ inch).· Item weight: 180 g. Applications:1. The controller is commonly used in residential homes to regulate the temperature of hot water or swimming pool. The controller measures the temperature of the water in the solar collectors and adjusts the circulation pump and/or mixing valve to ensure that the water is at the desired temperature.2. The controller can be used in larger-scale commercial and industrial applications, such as for air heating or process water heating. The controller regulates the temperature of the water in the solar collectors and adjusts the circulation pumps, fans and valves to ensure that the water or air is at the desired temperature with transfer heat to the place being heated.3. The controller can be used in greenhouses to regulate the temperature of the air and soil. The controller measures the temperature of the air and soil and adjusts the ventilation and heating systems to maintain a consistent temperature.4. The controller can also be used in solar cooling systems, such as absorption chillers. The controller measures the temperature of the solar collectors and adjusts the circulation pumps and valves to transfer heat from the collectors to the absorption chiller, which cools the air or water. Wiring:The unit is designed to be panel-mounted and comes with a wiring diagram for how to fix the main unit to your application systems.One Set Included:· 1 x Mini-Temperature Controller.· 2 x Temperature Waterproof Sensors (2m and 4m).· 1 x Instruction Manual.
