Cli-Mate’s Temp Controller (Tempcon-2020 series) is a plug-and-play temperature controller for managing grow-room climate devices. It monitors air temperature using a pre-assembled external probe and switches connected equipment automatically to hold a setpoint. The unit supports high-load appliances up to 16 A and works on 1-phase 220/230 V, with IP44 protection. Two operating modes allow control of a heater or a fan/air-conditioning device. A backlit digital display and keypad make setup simple, and the controller remembers the last settings after power loss. The package includes a 5 m sensor lead. Operating range is 10–60 °C. Compact housing uses heat-resistant, fire-retardant plastics. Approximate body dimensions are 55 × 40 × 135 mm, suitable for wall or bench installation in small or mid-size grows.
