What happens when weather data is not available?
This thermostat uses internet based weather data to generate an outdoor air
temperature reading for your home’s location. Outdoor air temperature is used as an
input for a few features (listed below).
If the internet connection to the thermostat is lost, it can continue to operate the
equipment normally for up to 8 hours from its last downloaded temperature and weather
forecast.
Without weather data, the equipment will operate as follows:
Smart Setback
– determines the optimal setback and ramp time between each
change in your schedule based on indoor temperature delta and historical
performance.
Auxiliary Heat Temperature
– the system will return to normal staging. Staging is
dependent on the Compressor minimum on-time, Compressor stage 2
temperature delta, Compressor stage one maximum run-time, auxiliary heat
temperature delta and auxiliary heat minimum delay time
Cooling Lockout
– unit will try to run whenever there is a call for cooling
Can I calibrate the
thermostat’s temperature reading?
Temperature sensors used in modern thermostats have defined tolerance intervals of
normal temperature readings. This means if multiple of the same thermostat model
were installed side-by-side, it would be normal for different current temperatures to be
displayed (e.g. one at 72
o
F and one at 71
o
F). However, there are product features and
installation steps you can take to help ensure a comfortable environment.
Installation best practices for temperature accuracy:
4. Minimize the effect of air leakage, excess wiring should be pushed into the
wall and the hole should be sealed to prevent air leakage.
5. Leave the thermostat installed & powered on for at least 30 minutes before
checking calibration.
If the thermostat reading still needs adjusting after these two installation steps, adjust
the Room Air Temperature Thermostat Offset. The thermostat is adjustable between
0
o
F and 5
o
F.
On Thermostat:
Select Menu > (hold) Service > Installation Settings > Thresholds > Temperature
