## Summary description

The FF RT-826 is a digital temperature regulator without probe, offering an adjustable control range from -25 to 130°C. It features a single changeover (1Z) contact rated 16 A and fits a 2-module DIN enclosure. Designed for temperature control tasks in heating, cooling or ventilation systems where an external sensor is used and compact modular installation is required.

## Long description

The FF RT-826 is a digital temperature regulator without an integrated probe, designed for modular DIN-rail installation. It provides an adjustable control range from -25 to 130°C and is built to operate with an external temperature sensor. The device occupies two modules in a standard DIN enclosure and offers one changeover contact with a 16 A switching capacity for controlling heating, cooling or ventilation equipment.
Advantages
The regulator delivers a wide temperature adjustment range suitable for diverse applications and supports precise setpoint control when used with a compatible external sensor. Its single changeover contact simplifies wiring for on/off control of loads up to 16 A, and the compact 2-module form factor allows installation in space-limited switchboards. The digital interface enables clear setpoint and status management while maintaining straightforward operation and integration into existing systems.
Suitable for
 Control of heaters and boilers with an external temperature probe
 Management of cooling units and compressors in small installations
 Ventilation and air-handling control requiring temperature-dependent switching
 Cabinet, enclosure, or small industrial processes where DIN-rail mounting is required
Key specifications
 Control range: -25 to 130°C
 Contact type: single changeover (SPDT)
 Contact rating: 16 A (resistive load)
 Module size: 2-module DIN-rail housing
 Sensor: requires external temperature probe (probe sold separately)
How to use
Install the regulator on a standard DIN-rail in the electrical enclosure and connect the external temperature sensor to the designated sensor terminals following the manufacturer's wiring diagram. Supply power to the device, set the desired temperature within the -25 to 130°C range using the front controls, and wire the controlled load to the changeover contact according to the load type and voltage. Verify correct operation by observing switching at the setpoint and adjust hysteresis or differential settings if available to prevent rapid cycling.
Usage recommendations
Use a sensor with appropriate accuracy and temperature range for your application, place the sensor where it reliably reflects the controlled medium temperature, and respect the 16 A contact rating when selecting connected equipment or use an external contactor for higher loads.
