Access Levels and Thermostat Lock
The 400 is shipped pre-programmed with common settings.
The 400 has an ‘Installer’ access level that allows full access
to all settings and a ‘User’ access level that restricts the
number of settings to only the Warm Weather Shut Down
and the temperature units. The 400 defaults to the ‘User’
access level after 12 hours of operation.
All thermostats are locked while the 400 is in the ‘User’
access level. Certain settings on the thermostat will be
unavailable while the thermostat is locked.
To change to the ‘Installer’ access level and Unlock the
thermostats:
In the Toolbox menu, locate Access
Adjust the access level to ‘Installer’ by pressing the up
or down button. This will permit setting changes to the
control.

Programming and Settings
The 400 settings can be found in the ‘Adjust’ menu. When
changing the items value, the setting is saved to the control’s
memory once the Item button is pressed to advance to the
next item, or after 60 seconds, the control times out and
reverts back to the ‘View’ menu.
All settings are stored in permanent memory and will be
kept correctly during any loss of power.
