Know before you buy
No. The PRO24 is engineered exclusively for 24V HVAC systems. Using it on a 120V circuit will cause immediate failure and is not supported.
It provides a barrier against electrical transients, power surges, lightning strikes, and amp spikes. These events are common culprits behind the failure of sensitive HVAC control boards.
While the installation process is straightforward, it involves wiring into your HVAC transformer leads. If you are not comfortable working with electrical components, it is best to have a qualified HVAC technician handle the installation.
A secure ground connection is essential for the device to safely divert excess electrical energy away from your equipment. Without a proper ground, the surge protector cannot effectively neutralize voltage spikes.
Yes, the line side wires come equipped with an inline fuse. This provides an extra layer of protection for your system's circuitry during an electrical event.
