The PNI CT25PW is a premium, in-wall smart WiFi thermostat designed to bring intelligent temperature management and energy efficiency to your home heating system. Offering full compatibility with underfloor water heating, water pumps, thermal actuators, and residential gas boilers, this modern white thermostat features a non-energized (dry contact) relay output capable of switching up to 16A. Seamlessly integrating into your smart home ecosystem, it connects directly to your 2.4 GHz WiFi network to offer effortless voice control via Amazon Alexa and Google Assistant, as well as complex smart automation scenarios using the popular Tuya Smart and Smart Life mobile applications.
Engineered with a dual-sensor architecture, the PNI CT25PW includes an integrated ambient air sensor to monitor room temperature and an external 3-meter wired floor probe to keep track of underfloor temperatures. Operators can configure the thermostat to run in three distinct monitoring modes: relying solely on air temperature, floor temperature, or dynamically balancing both sensors to prevent subfloor overheating while maintaining optimal room comfort. Its clear, backlit LCD screen presents the current room temperature, time, and active mode at a quick glance, while a key lock function acts as a child-safety safeguard to prevent unauthorized setting changes.
For maximum convenience and energy conservation, the thermostat supports versatile programming configurations. You can establish custom 7-day schedules with up to 4 distinct temperature periods per day, run the device in full manual mode, or activate the Eco (anti-freeze) setting when traveling. Built-in smart features like “Open Window Detection” automatically shut down heating cycles during sudden room temperature drops to eliminate energy waste. With its sleek, flush-mount profile and high-performance plastic housing, the PNI CT25PW beautifully combines modern styling with advanced climate control automation.
