Purchase now: Pfannenberg 17099610030 FLZ 530 Twin Thermostat
Purchase now: Atlantech Drives provides you the Pfannenberg 17099610030 (Model: FLZ 530), a space-saving Twin Thermostat that integrates two independent thermal controls into a single DIN-rail mountable unit. Managing both heating and cooling in outdoor cabinets or unconditioned warehouses is critical to prevent condensation (too cold) and overheating (too hot). The FLZ 530 simplifies this by providing one dial for your heater and a separate dial for your filterfan.
Dual-Function Control Logic
The FLZ 530 features two color-coded dials:
- Red Dial (NC Contact): Normally Closed. Opens on temperature rise. Used to turn off Heaters when the cabinet is warm enough.
- Blue Dial (NO Contact): Normally Open. Closes on temperature rise. Used to turn on Filterfans when the cabinet gets too hot.
This dual capability allows for completely autonomous climate control without needing a PLC or complex wiring harness.

- Model: FLZ 530.

Expert Installation Advice: Setting the «Dead Band»
The most common mistake with twin thermostats is setting the temperatures too close together. Expert Tip: Always maintain a «Dead Band» of at least 10-15°C between the heater setpoint and the fan setpoint. For example, set the Heater (Red) to 10°C and the Fan (Blue) to 35°C. If you set them both to 25°C, they might run simultaneously due to hysteresis overlap, wasting energy and fighting each other (heater heating the air the fan is trying to exhaust).
Frequently Asked Questions (FAQs)
Q: Can I use this for 24V DC?
A: Yes, the mechanical contacts can switch DC loads (check max wattage curve, typically ~30W). For higher DC loads, use an interposing relay.
Q: Where is the best mounting position?
A: Mount it in the upper third of the cabinet, away from the direct discharge of the heater or fan, to ensure it senses the true average air temperature.
