Key benefits and why you need this product Precise temperature control: lets you choose cooling or heating so a single controller handles both modes and keeps environments within target ranges. Reliable equipment protection: built‑in delay protection prevents rapid cycling of refrigeration equipment, reducing wear and compressor stress. Accurate readings and adjustment: set a temperature set point, define the differential (hysteresis) to control when outputs switch, and use the calibration function to correct sensor offsets for accurate monitoring. Versatile and practical: useful wherever dependable temperature regulation is needed, with straightforward settings for fast setup and stable operation. What it does (functions) Mode selection: change between cool and heat modes to control either cooling or heating outputs as required. Temperature set point and differential control: set the desired temperature and the difference value to determine when the controller switches outputs, allowing stable, controlled cycling. Temperature calibration: adjust the controller’s temperature readout to correct for sensor or measurement offsets and improve accuracy. Refrigeration delay protection: includes protection that enforces a delay before reactivating refrigeration output to prevent rapid on/off cycles and protect equipment. Customer-facing attributes Function: Dual-mode thermostat functionality (cooling and heating), set point and differential control, calibration, and delay protection. Compatibility: Designed to manage refrigeration or heating control outputs where set point, hysteresis, and anti-short-cycle protection are required. Performance: Enables precise temperature maintenance and reduces mechanical stress on compressors and related equipment. Simplicity: Clear controls for set point, differential, and calibration make it straightforward to use and adjust for specific installations. Typical use scenarios Small cold rooms and refrigerated cabinets: Maintain target temperature with set point and differential settings; delay protection prevents short cycling of the compressor after a shutdown or power interruption. HVAC zones or workshop spaces with supplemental heating: Switch to heat mode to maintain a minimum temperature and use calibration to align controller readings with a reference sensor. Laboratory incubators or temperature‑sensitive storage: Use precise set point control and the calibration function to keep samples within narrow tolerances while preventing frequent compressor starts. What to expect in operation Set the desired temperature set point and the differential to define when the controller switches outputs. Use the temperature calibration function when sensor readings need fine adjustment. Enable or rely on the built‑in refrigeration delay protection to prevent immediate reactivation of refrigeration outputs after they turn off, extending equipment life and improving reliability. No extraneous features are added here — the description reflects the product’s core functions: change modes between cool and heat; check and control temperature via set point and difference value; support temperature calibration; and provide protection against refrigeration control exit delays.
