Will it harm my A/C compressor?

Absolutely not. First, consider that modern HVAC systems are equipped with built-in mechanisms to protect your compressor. These include delay timers and high/low pressure cut-outs.

Second, our HSRS controller features a configurable shut-off delay. This setting defines the length of time that a door or window must remain open before HVAC shut-off occurs. It ensures the HVAC system is not shut down unless the violation persists, thereby minimizing compressor cycling. For many applications, two minutes or greater is a reasonable duration.

Lastly, the HSRS is also equipped with a configurable re-activation delay that defers system restart following a door / window violation. Though this feature is completely optional for most installations, we find that some customers prefer to deploy it for added peace of mind.
