Regulate line-voltage HVAC systems.

Commonly used with hydronic heaters, this thermostat senses the temperature of liquids. The thermowell protects the sensor.

Place sensor in enclosures or different rooms than the rest of the thermostat to control temperature from outside the space. Thermostats work with line-voltage HVAC systems.

Place sensor in enclosures or different rooms than the rest of the thermostat to control temperature from outside the space.

These thermostats work with low-voltage HVAC systems that have only one speed.

Connect to a Wi-Fi network so you can remotely program, monitor, and control the temperature from a computer, tablet, or smart phone.

As the temperature goes up, the pressure in the system goes up.

Actuators automatically switch between incremental and proportional control to adjust dampers to regulate airflow.

These actuators provide better control than incremental actuators because they are constantly being positioned in response to duct airflow requirements.

For use with equipment that cycles on and off, these relays meet UL 508 for air conditioning and heating. Also known as definite-purpose contactors.

Also known as barometric dampers, these dampers improve furnace performance by automatically opening and closing to maintain consistent airflow despite changing environmental conditions.

Save energy and increase comfort by heating and cooling only the areas that need it.

Increase airflow through exhaust duct to improve furnace performance.
