691744-2

The 691744–2 is a widely used energy saving device that was developed in the early 2000s. It is ideal for use in residential, commercial, and industrial applications. The device is straightforward and easy to install and is perfect for energy saving applications such as HVAC and fan operations or wherever a fair amount of energy is wasted when not in use.

A 691744–2 device works by maintaining a temperature range that is implemented via a modulating controller, like a programmable thermostat or manual switch. The device alternates between full off and full on capabilities, meaning that it only runs when it is needed. This greatly reduces the waste of energy by eliminating the standby use of equipment that can occur when running at a constant, moderate setting.

691744–2 devices can be applied to many different pieces of equipment to serve a variety of energy-saving uses. One example is when it is used in an HVAC system to manipulate the cycle off rate. By using the device, the system can detect the different needs of a space, such as a time of day when a room is unoccupied, and shut down accordingly.

Other uses of the 691744–2 device include the direct control of fans in building ventilation systems or mechanical systems. In this scenario, the device can be used in place of a timer or motor-start controller to control the fan speed. By controlling fan speed, the device can reduce energy losses associated with leaving the fan idle or running too fast or slow when not necessary.

The 691744–2 can also be used in refrigeration systems to moderate whole system components like compressors, condensers, and evaporators. Each of these components can be shut down or run at reduced levels when not in use, significantly reducing the amount of energy used when running. This is most useful in applications like cold storage units where the equipment continues running even when not in use.

When put to practical use, the 691744–2 device can save a great amount of energy in residential and commercial applications. The energy savings are even greater when used in industrial applications. The device is very cost-effective and easy to install, making it an ideal solution for anyone looking to reduce their energy bills and improve the efficiency of their systems.
