Pfannenberg 17141000000 FLZ 541 – Twin Thermostat for Heater and Fan, 0–60 °C, N.C./N.O.
The Pfannenberg 17141000000 is an FLZ 541 twin thermostat: two independent thermostats in one housing. One controls a cabinet heater through an N.C. contact (red dial). The other controls a Filterfan® or cooling unit through an N.O. contact (blue dial). Each has its own setpoint between 0 and 60 °C, so you can set separate switching points for heating and cooling.
A single DIN rail device covers complete cabinet climate control, protecting against condensation in cold conditions and against overheating when temperatures rise. It is UL Recognized for easy integration into UL 508A panels.
