Dual temperature control and display: Manage heating and cooling together with a dual sensor interface and a split digital display. Quickly view current versus set temperatures at a glance for aquariums, incubators, vivariums, greenhouses, or fermentation setups. Wide voltage compatibility: Runs on 12V/24V or 110220V AC, making it easy to deploy across UK and EU power scenarios. Choose the supply that fits your build, from DIY projects to home HVAC control for heaters, fans, or chillers. Precise range and accuracy: Temperature control from 20C to +80C with 0.1C resolution and tight hysteresis settings to stabilize swings. Relay output rated 10A handles resistive loads for space heaters, heat mats, cooling pumps, and exhaust fans. Reliable build and mechanism: ABS flameretardant housing with a cooling grid design to support heat dissipation and steady performance. Intuitive buttons and a clear digital display simplify setup; separate probe leads improve placement flexibility. Typical applications: Aquarium, reptile enclosure, or terrarium temperature stabilization where simultaneous heating and cooling management is beneficial. Incubation or fermentation chambers requiring precise, stable temperatures with flexible sensor placement. Greenhouse climate control or small HVAC projects that involve heaters, fans, or chillers and benefit from clear readouts and robust construction.
