locked out of thermostate


From the manual:



PROGRAMMABLE KEYPAD LOCK
To prevent tampering with any of your settings or
temperatures, the front panel buttons and the rotary dial can
be locked out, requiring a four digit code to unlock them.
You may use either the default lock code of "0000", or your
own personal number combination (see "Changing The Lock
Code")


LOCKING THE THERMOSTAT: Ensure the rotary dial is in the
RUN position. Press the NEXT button for at least 2 seconds.
The words "ENTER CODE" will appear on the screen, along
with "0000". Press the NEXT button again for at least 2
seconds. A padlock should appear on the screen to confirm
that the thermostat is now locked.


LOCKING THE THERMOSTAT: Ensure the rotary dial is in the
RUN position. Press the NEXT button for at least 2 seconds.
The words "ENTER CODE" will appear on the screen, along
with "0000". Press the NEXT button again for at least 2
seconds. A padlock should appear on the screen to confirm
that the thermostat is now locked.

UNLOCKING THE THERMOSTAT: Ensure the rotary dial is in
the RUN position. A single press of any button should cause
the words "ENTER CODE" to appear on the screen, along
with "0000". If the default code was used to lock the
thermostat, press the NEXT button for at least 2 seconds.
The padlock should disappear from the screen, and the
thermostat should now be unlocked.
If you try to unlock the thermostat by entering a code that is
not correct, a padlock and the digits "88:88" will flash on the
screen and you will have to try again. If a lock code
different from the default was used, this will need to be
entered by using the UP/DOWN buttons, and the NEXT
button to advance to the next digit. Once the correct code is
entered, press the NEXT button for at least 2 seconds and
the thermostat should now be unlocked.


CHANGING THE LOCK CODE: To create your own specific
lock code, first ensure that the rotary dial is in the RUN
position. Press the NEXT button for at least 2 seconds. The
words "ENTER CODE" will appear on the screen, along with
"0000". Now press the HOLD button again for at least 2
seconds. The words "SET CODE" will appear on the screen,
along with "0000".

IF YOU FORGOT YOUR LOCK CODE: You can still unlock the
thermostat by performing the following steps: On the back
of thermostat locate JP1, which is a row of 3 metal pins at
the right edge of the circuit board above the battery tray.
There should be a plastic jumper cap on 2 of the 3 pins
(right or left).


Move the jumper cap so that it is on the opposite 2 pins.
For this change to be recognized, move the Temperature
Mode switch to any other position than its current one.
These steps listed should have changed the lock code back
to the default of "0000". Follow the instructions already
listed in "UNLOCKING THE THERMOSTAT".
