Precision Adjustable Thermostat Controller

Dimensions: approx. 7.9 x 4.3 x 2.6 cm (3.11 x 1.69 x 1.02 in), weight not specified. Housing material: durable black plastic. Operating voltage supports both DC (5V/12V/24V) and AC (100–220V) input, ensuring compatibility with diverse power sources across UK and EU installations. Temperature measurement range: -50°C to +110°C, with resolution of 0.1°C between -9.9°C and 99.9°C, and 1°C outside that range. Measurement and control accuracy: ±0.1°C. Includes a 1 m NTC waterproof temperature probe for reliable sensing in humid or wet environments such as water tanks or refrigeration units. Features a single relay output rated at 20A, suitable for driving compressors, heaters, fans or solenoid valves. LED display provides clear, high-contrast readout under ambient lighting conditions. All user settings are retained after power interruption or short circuit, eliminating repeated configuration. Designed for stable operation in ambient temperatures from -10°C to +60°C and relative humidity 20–85% RH. This thermostat supports both heating and cooling mode control — ideal for bidirectional temperature regulation in freezers, refrigerators, industrial chillers, steamers and custom thermal systems. Its wide operating range and robust relay output make it suitable for domestic, light commercial and small-scale industrial applications across the UK and Europe.
