SAS968FHL GFCI electric heating thermostat for electric heating systems

Product Features

Class A 5mA Safety Protection

Built‑in Class A GFCI detects ground‑fault currents as low as 5mA and interrupts power within 25ms—protects users from electric shock and meets UL 943 requirements without external breakers.
Double-Pole Relay Isolation

Double‑pole relay disconnects both live and neutral conductors simultaneously—ensures complete circuit isolation for safe servicing and troubleshooting.
16A Load Supports Systems up to 3500W

16A relay drives systems up to 3500W—handles high‑power loads with a single SKU across residential and light‑commercial applications.

Dual Sensor Control for Room & Floor

Dual sensors monitor ambient air and floor surface simultaneously—maintains room comfort while preventing floor material stress from excessive heat.
Intelligent Recovery Technology

Learns system heating response and activates early—ensures programmed temperatures are reached precisely at scheduled times, eliminating cold starts.
Open Window Detection

Detects sudden temperature drops from open windows and automatically suspends heating—stops energy waste the moment it occurs.
