FAQs
The thermostat uses a Three-Four wired connection with external 230 V AC power. It provides a single normally open heater output and accepts conductors up to 4 mm². For installation, mount with a 20 mm depth and connect the EXT wiring to enable external control on the same phase. Ensure enclosure IP21 suitability and proper cable routing.
Key specs include rated voltage 230 V AC ±10% at 50 Hz, measuring range 5–35 °C, one heater output (NO), seven switching programs, external control via EXT connector, resistance sensor 10 kΩ (NTC), standby power 0.05 W, and IP21 protection. The device operates with external power supply and supports Week clock intervals for scheduling.
Yes, the device is IP21 rated, making it suitable for indoor enclosure environments where splash protection is not a primary concern. It is designed for controlled industrial spaces, electrical cabinets, and process areas. It is not intended for outdoor or explosion-hazard locations, and it carries CE, RoHS, and REACH compliance for safe indoor operation.
The thermostat is covered by CE declarations of conformity for TB16xx, TC16xx, and TF16xx series, along with RoHS and REACH declarations. It also references SCIP and WEEE classifications, an EPD for the combination thermostat, and ETIM 9 classification EC011309 for room clock thermostat, ensuring regulatory alignment.
The device reduces total cost of ownership through very low standby power (0.05 W), pre-programmed multiple switching programs, and easy external control, which lowers commissioning time and ongoing maintenance costs. Energy efficiency, compact mounting, and standardized certifications also reduce downtime and improve process stability in automated manufacturing environments.
