Frequently asked questions
FAQ
ANSWER
When can I get the firmware OTA
update for humidity control?
OTA updates are pushed via Wi-Fi after being
registered to the customer's account on the Sensi app.
Sensi Touch (1F95U) and Sensi (1F87U) smart
thermostats are all backward compatible. 1F86U
and UP500W models are currently not compatible.
Which versions of Sensi thermostats are
compatible with humidity control?
What terminals should I use to
enable humidity control?
Use Y2/* for humidification and
W2/* for dehumidification.
Humidifiers: Any 24VAC humidifier. Currently,
Sensi does not support independent
(call for heat) humidification.
What types of humidifiers and
dehumidifiers are supported?
Dehumidifiers: HVAC systems with dehumidify
mode (slowing of the system's fan speed) or 24VAC
dehumidifiers. Currently Sensi does not support
independent (call for cool) dehumidification.
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 an appropriate humidity setpoint?
What is overcooling to dehumidify?
On air conditioning systems without a
dehumidifier, the dehumidification feature allows
Sensi to overcool to a maximum of 3⁰ below
the AC setpoint to help control the humidity.
Overcooling is an option to dehumidify without
having to wire additional accessories.
During extremely cold and dry or hot and
humid climates, your humidifier or dehumidifier
may not be able to increase or decrease
humidity enough to reach your setpoint
depending on the size of your equipment.
Why is my system unable to reach
my humidity setpoint?
