JINING, Shandong, China \u2013 May 17, 2026 TWJ, a national high-tech integrated manufacturer specializing in PCBA boards, HVAC controls and EV chargers, officially launches the PDT1-8333 Ascent programmable thermostat, a cost-effective controller tailored for electric and hydronic underfloor heating systems across 39 Eurasian markets including EU 27 nations, UK, Switzerland, Norway, Iceland, Russia, Belarus, Turkey and five Central Asian countries.<\/p>\n\n\n\n
Manufactured in-house on our 11 JUKI automatic SMT lines, this 230VAC thermostat fully complies with BS7971 and EN 60364 EU wiring standards. It adopts a slim 14mm 86\u00d786mm standard European wall design, compatible with 35mm deep back boxes for simple residential and commercial installation.<\/p>\n\n\n\n
1.High Load & Accurate Temperature Control Rated 16A maximum current with 3680W output, compatible with both electric and water underfloor heating. Equipped with 10K 1% precision NTC sensor, delivering \u00b11\u00b0C temperature accuracy. Three sensor modes (internal \/ external floor probe \/ dual sensors) avoid floor overheating risks.<\/p>\n\n\n\n
2.Flexible Weekly Energy-Saving Schedules Supports 5+2 \/ 6+1 weekly programming, with six adjustable time segments per day for wake-up, away and sleep modes. Built-in holiday mode further cuts idle heating consumption, fully meeting EU ErP low-power requirements with standby power below 1W.<\/p>\n\n\n\n
3.Multi-Layer Safety Protection Integrated anti-freeze low-temp startup and overheat forced shutdown functions. Sensor fault alert (Err\/E1\/E2 codes) automatically cuts heating output to prevent hazards. All-pole disconnect design meets EU electrical safety specifications.<\/p>\n\n\n\n
4.User-Friendly Operation & Memory Retention Clear backlit LCD with two brightness modes (auto-off after 10s \/ always on). Dual child lock modes lock single power key or all buttons to prevent misoperation. Non-volatile memory retains all schedules and parameters after power outages.<\/p>\n\n\n\n
Installer-Adjustable Advanced Parameters Hidden professional setting menu allows free calibration: temperature compensation (-9\u2103 ~ +9\u2103), heating hysteresis (1\u2103~5\u2103), temperature upper limit (5\u2103~99\u2103) and power recovery logic, adapting to villas, apartments and heating renovation projects.<\/p>\n\n\n\n
Every unit undergoes 72-hour full-load aging, high-low temperature cycling and insulation testing in our dedicated reliability lab before shipment. Stable working range: 5\u00b0C\u201345\u00b0C with IP20 indoor protection rating.<\/p>\n\n\n\n
