The Pro Therm 1882-SF temperature controller with digital display, fault indicator, and operating hours counter is designed for the reliable control and monitoring of electrical underfreeze protection systems. It enables precise temperature control and ensures that connected heating circuits are automatically switched on or off as soon as the set temperature limits are reached.

The integrated digital display allows the current temperature to be read directly on the device at any time. Simultaneously, the fault indicator enables early detection of malfunctions, such as sensor failure or impermissible temperature deviations. This ensures a high level of system reliability.

The controller also features an operating hours counter, which records the operating times of the connected heating systems. This simplifies system monitoring and the planning of maintenance intervals.

Thanks to its compact design and easy integration into control and heating systems, the 1882-SF temperature controller is particularly suitable for use in frost protection systems in cold storage and freezer warehouses, as well as in frost-prone foundation and floor areas.
