Thermostats are used as temperature controllers to manage filter fans or cabinet heaters. They are designed as openers/closers and changeover switches. In combination with cabinet heaters, they can ensure, especially in outdoor applications, that the cabinet is 'artificially' dehumidified in addition to temperature control. This means that the temperature is maintained above the dew point to prevent water from condensing out of the air, which could lead to short circuits due to condensation. The combination with filter fans offers additional savings in energy, materials, and time, resulting in a better environmental balance and increased safety in the production process through reduced energy consumption and improved efficiency of the filter fans.

The series of twin thermostats combines two thermostats in all combinations for complex switching tasks.

FLZ510 as a changeover switch with snap contact:

• Suitable for controlling fans and heaters
• Switching temperature difference 1 K
• Switching point tolerance +/- 3 K
• Setting range 20 °C to 80 °C

Thermostats for every application:

• FLZ510: Changeover switch with snap contact
• FLZ520: Opener with snap contact (suitable for controlling heaters)
• FLZ530: Closer with snap contact (suitable for controlling fans)
• FLZ541: Opener and closer with snap contact in one housing
• FLZ542: Two openers with snap contact in one housing
• FLZ543: Two closers with snap contact in one housing
