Pfannenberg 17142000000 FLZ 542 – Twin Thermostat for Two Heaters, 0–60 °C, N.C./N.C.
The Pfannenberg 17142000000 is an FLZ 542 twin thermostat. It combines two independent thermostats in one housing, each with a normally closed (N.C.) contact. Each contact opens when the cabinet temperature rises above its setpoint, so the unit can control two heaters, or two heating stages, at different switching points from 0 to 60 °C.
This gives staged heating control in a single DIN rail device. For example, one heater can switch on to prevent condensation and a second can add frost protection at lower temperatures.
