Frequently Asked Questions
| FAQ | Answer | |
| Firmware Update | When can I get the firmware OTA update for the humidity control? | Firmware updates for humidity control are automatically installedonce a Sensi smart thermostat is connected to the internet |
| Which versions of Sensi thermostatsare compatible with Humidity control? | Sensi Touch (1F95U) and Sensi Classic (1F87U) thermostats are all backward compatible. 1F86U and UP500W models are currently not compatible. | |
| Installation& Configuration | What terminals should I use toenable humidity control? | Use Y2/* for humidification and W21* for dehumidification |
| What types of humidifiers and dehumidifiers are supported? | Humidifiers – Any 24VAC humidifier. Currently, Sensi does not support independent (from a call for heat) humidification.Dehumidifiers – HVAC systems with a dehumidify mode (slowing of the system’s fan speed) or 24VAC dehumidifiers. Currently, Sensi does not support independent (from a call for cool) dehumidification. | |
| Using the Feature | What is an appropriate humidity setpoint? | Depending on the outdoor temperature, the ideal indoor humidity level is between 30-50% RH. In cold weather, if condensation appears on your windows, lower the humidity setpoint. |
| What is Overcooling to Dehumidify? | On-air conditioning systems without a dehumidifier, the dehumidification feature I allow Sensi to overcome to a maximum of 3° below the AC setpoint to help control humidity. Systems with de hum terminals on the air handler or wired dehumidifiers on will use those capabilities rather than overcooling. | |
| Why is my system unable to reachmy humidity setpoint? | During extremely cold and dry or hot and humid climates, your humidifier or a dehumidifier may not be able to increase or decrease humidity enough to reach your setpoint depending on the size of your equipment |
