So I'm trying to protect a 5 ton heat pump from power flaps, the
kind that occur when heavy winds blow trees across the primary feed
to a rural home.
The HVAC industry seems to have some prepackaged solutions, such as the
ICM491 <www.icmcontrols.com/downloads/icm491_ig.pdf> but I'm wondering..
It seems to say it samples the power for 5 seconds before acting. That
strikes me as way too slow. I want to drop the compressor offline in a
second or two, so it does not attempt to resume after falling to say half
speed or so.
But it appears to be popular in the HVAC industry...
What say the learned ones here?
