Aprilaire 8870 Thermostat User Manual


 
THERMOSTAT BUTTON LOCKOUT This feature disables the buttons of the thermostat
completely, or to a limited degree. For example, the MODE and FAN status can be set
and then locked, so the buttons will not allow those settings to be changed. Additionally,
this can be set to allow changes for a limited time and amount of change. For example,
you can limit temperature changes to
±
3°, if desired (see Figure 6).
SECURITY SET-UP This prevents unauthorized individuals from accessing Thermostat
Set-Up. A code can be setup that must be entered to gain entry into Thermostat Set-Up.
Master key pass word is 7777 (see Figures 7 and 8).
