FLZ 541-543 SERIES

TWIN THERMOSTATS

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. All models feature universal temperature control dials with both Fahrenheit and Celsius ranges. Housing: ABS high temperature plastic


Flexible Mounting Options

Unit can be direct mounted or connected to a standard DIN rail without tools using the included snap fastener.

Universal Temperature Dial

All models utilize universal temperature control dials with both Fahrenheit and Celsius ranges.

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.

Energy Saving 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.

UL Certified

Thermostats are UL Recognized to NITW2 and NITW8 standards allowing for easy integration into UL 508A panels.
