LOCK FUNCTION (with PIN)
This menu option may be used to enable a LOCK function protected by a
numerical access code to prevent tampering (see page 12).
From the advanced menu, press
OK
repeatedly to view the following
screen:
To set the display lock only, set 000 as the PIN with the
and
keys.
To set the PIN-protected thermostat lock function (to prevent tampering),
set a PIN number between 001 and 999.
After enabling the lock function, from the main screen, press and hold
for 3 seconds to lock the display (see page 11), or press and hold
for 3
seconds, enter the PIN set previously, then press
OK
to confirm to activate
the anti-tampering lock (see page 12).
Perform the same procedure to unlock.
NOTE
Enter the emergency unlock code 513 if you have forgotten the PIN.
After unlocking the unit with the emergency unlock code 513, it is strongly
recommended to access the advanced menu and check and/or modify the
user-defined PIN set previously.
