Programming the
TCM18
The TCM18 has an electronic password security provision. To access the program-
ming mode, enter the 4 digit numerical security code. If no code has been entered,
press the PROG key followed by the ALARM ACK key and subsequently followed by
the PROG key. Next, successively select a numerical code using the UP and DOWN
arrow keys along with the ENTER key. An entry of 0000 will deactivate the security
code feature. Note that once a security code has been entered, the user has un-
limited access as long as activity is present. A period of inactivity of 30 minutes or
more will result in programming access being denied. At this point, re-entry of the
security code will be required. If the security code is forgotten at some future date,
enter a value of 1954 (during the first 5 minutes after power is applied to the TCM18)
as the security code, then a new code may be entered by pressing the ALARM ACK
key and subsequently followed by the PROG key.
To program circuit control settings or control parameters, multiple keys in sequence
will need to be pressed. For example, to change the settings associated with the
MAINTAIN TEMP key, first press the green PROG key.
