Ecovent will disable itself if it detects unsafe conditions.

Low Vent Temperature

If Ecovent detects a very low vent temperature it will disable your Ecovent system to prevent unsafe conditions for your compressor, which could happen if you turn your AC on prematurely. Switch your HVAC mode to Heat and enable the system to clear this alert.

Most manufacturers recommend at least three consecutive days of temperatures above 65 degrees to start up your AC in the springtime. And not to run your AC if it is below 60 degrees as it can cause damage to the compressor.

Additionally there must be power to your compressor for at least 3 hours before starting it. This allows an electric coil to warm the compressor, vaporizing the liquid refrigerant. Liquid refrigerant in an operating compressor will damage it.

High Vent Pressure

Ecovent sets safe pressure boundaries, and when the system detects pressure outside of these boundaries it will disable itself to protect the HVAC unit. Those boundaries use the highest and lowest ever recorded atmospheric pressure on earth, but since they were taken at sea level we sometimes see pressure outside of these boundaries in higher elevations.

If this happens please email and we'll adjust the pressure boundaries for your system. We plan to roll out a fix to all systems soon.

When your system is disabled your thermostat will continue to function traditionally and your vents will remain open.
