WARNING: Changing settings in the SETUP can damage the HVAC system and should only be
done by a qualified HVAC technician.
Password
Two levels of password protection are programmed in this thermostat: USER and INSTALLER.
Both password levels will timeout after 20 minutes of the last button press and force you to re-enter
a password.
The default INSTALLER password is INST. The INSTALLER password limits access to critical
thermostat settings which include:
• Password • Equipment Settings
• SETPOINT Range • Control
• Equipment Type • Reset
The passwords can be changed in the PASSWORD menu.
SCROLL to change either USER or INSTALLER password.
SCROLL through the letters to change the password, or use
the blank letter to set the password to a blank.
