Описание к видео [FIXED] Nest Thermostat E74 No power to Rh wire detected.

This video shows how I fixed an error with my Nest thermostat. The error is E74 - No power to Rh wire detected. Learn more at nest.com/e74. In my case this was caused by a clogged drain line. Using a wet dry vac to clear out the lines resolved it.
