SETTING UP WI-FI
To display the SETUP WI-FI screen, press:
•
if the thermostat is connected to a Wi-Fi network
•
if the thermostat is not connected to a Wi-Fi network
t
Except for the SETUP WI-FI screen, which can be changed
from NO to YES, the information in the Wi-Fi settings screens is
read-only and cannot be changed.
The Wi-Fi screens have a fixed timeout of 60 seconds.
Connect to a network
If the thermostat is not connected to a Wi-Fi network and NO is
displayed on the SETUP WIFI screen, follow these steps to
connect the thermostat to a network:
1.
Press the SELECT button.
2.
Change NO to YES.
3.
Press SAVE.
NOTE: This puts the thermostat into the setup mode and ready to
receive Wi-Fi join commands.
The thermostat is already in the setup mode if SETUP WI-FI
was changed from NO to YES in the past 2 minutes or if the
installer disconnected from a Wi-Fi network in the past 2 minutes.
Figure 30 indicates that the thermostat is ready to join a Wi-Fi
network. If the thermostat is connected to a Wi-Fi network, the
SETUP WI-FI screen is not displayed.

NOTE: The SELECT button is not displayed because the
thermostat is already in the setup mode.
SSID
When the thermostat is not connected to a Wi-Fi network, the
SSID is a factory-configured value that starts with CMML
followed by 12 numbers. The SSID scrolls across the top of the
display for 5 seconds and then displays only the 12 digits for the
remainder of the screen timeout time. The user needs these 12
digits to connect to the WIFIStat Mobile App.
SSID - Scrolls for the first 5 seconds
CMML- Scrolls after 5 seconds
When the thermostat is connected to a Wi-Fi network, the network
SSID is displayed.
MAC address
The MAC address is a unique 12-digit identifier associated with
the Wi-Fi radio chip that contains the letters A through F and the
numbers 0 through 9.
DSN
The DSN is the name used to identify the thermostat in the WIFI-
Stat Mobile App. The name starts with the letters AC followed by
13 letters and numbers. The DSN scrolls across the top of the dis-
play.
Registration
When the thermostat has been successfully registered to a user
account with the WIFIStat mobile app, the registered status
displays YES.
When the thermostat is not registered to a WIFIStat user account,
the status is NO.
TIMERS, MEMORY, AND DEADBAND
MINIMUM OFF timer
Once a heating or cooling demand is satisfied on the thermostat,
the MINIMUM OFF timer is set to a 300-second value (5
minutes) and then begins to count down each second. Heating and
cooling outputs are de-energized the entire time that this timer has
a value greater than 0.
MINIMUM ON timer
Once a heating or cooling output becomes active, the 5-minute
MINIMUM ON timer begins to count down. The output will not
de-energize until the timer reaches zero and the demand is
satisfied. If the user changes the setpoint to satisfy the demand, the
5 minute minimum on time is ignored and the heating or cooling
equipment turns off.
Non-volatile memory
The thermostat can store settings in non-volatile memory to ensure
that settings remain the same after a power outage (either
intentional or unintentional). Items stored in non-volatile memory
include:
•
Installer settings
•
Menu settings
•
Program schedule
•
Date and time
•
Software information
•
Dealer information
•
Fault and system event information
Deadband
The thermostat controls the number of degrees (°F or °C) between
the heating and cooling setpoints. If the user changes a setpoint
that violates the deadband requirement, the opposite mode set-
point is "pushed" to enforce the deadband. The deadband setting is
fixed at 2°F.
