Pfannenberg Thermostats : Why it Matters
Thermostats are used as temperature controllers and, therefore, for the control of Filterfans® or electrical enclosure heaters. They are available with N.C. (normally closed) / N.O. (normally open) and changeover contacts.
Twin thermostats are switching units in various temperature ranges, they use less space than 2 single devices which saves energy and reduce costs.
In combination with control cabinet heaters you can ensure, besides temperature control, that the control cabinet is ‘artificially’ dehumidified, in particular in outdoor applications. That means that the temperature is kept above the dew point so that no water condenses out of the air, which could lead to short circuits due to the formation of condensation.

Easy Mounting Options
Unit can be connected to a standard DIN rail without tools using the included snap fastener.
Ultra Compact Design
At slightly over 2″ wide and just over 3″ tall, this compact design easily installs into areas that have a limited installation space.
Durable Long Lasting
With its rugged design and solid construction you can count on the FLZ Thermostat to perform consistently over a long period of time.
Independent Controls
Control dials are color coded based on the model. The FLZ 541 comes with a red dial for controlling the heater and a blue dial for controlling the fan. The FLZ 542 comes with 2 red dials for controlling 2 heaters or a heater and alarm. The FLZ 543 comes with 2 blue dials for controlling 2 fans or a fan and alarm.
UL Certified for 508A Panels
Thermostats are UL Recognized allowing for integration into UL 508A panels.
Energy Savings Solution
One unit can control two separate devices. When controlling a Filterfan® the FLZ Twin Thermostat can control the operation of the fan, turning it off and on based on a set temperature. When also controlling a heater, the FLZ Twin Thermostat can turn the heater on and off based on enclosure temperature. This provides an environmental balance through energy reduction.
Our FLZ 510-530 Series of Thermostats are available in 3 different models. The FLZ 510 comes with a change over contact, the FLZ 520 comes with a N.C. contact and the FLZ 530 comes with a N.O. contact. These are designed to work with cabinet heaters and Filterfans® to control the internal cabinet temperature. Available in 3 models. Housing: ABS high temperature plastic
Our FLZ Series of Twin Thermostats are available in 3 different models. The FLZ 541 comes with N.C/N.O contacts, the FLZ 542 comes with N.C./N.C. contacts and the FLZ 543 comes with N.O./N.O. contacts. Unlike a single thermostat with changeover contacts, connected devices can be switched to different temperature ranges to manage the internal cabinet temperature. Housing: ABS high temperature plastic
