GETTING STARTED
1. Install the control as described on page 3.
2. Wire your control following the instructions on page 3 and drawing on page 4.
3. Most controls do not need many (if any) program changes to work on your process. For best
results if programming changes are necessary, make all the necessary changes in the
SECURE MENU (page 7) before making changes to the SECONDARY MENU (page 6). If
error messages occur, check the Diagnostic Error Messages on page 10 for help.
Take the example of a Model CT15011 that comes from the factory programmed for type J
thermocouples. Suppose for this example you wish to change the input to type K and limit the
set point range between 0° and 1000° C.
First, enter the SECURE MENU as instructed on page 7. Press the INDEX key until the display
shows
Inp
and press the DOWN ARROW until the display shows CA. Don't forget to press the
ENTER key to retain your setting.
Next, press the INDEX key to display
F-C
. Press the DOWN ARROW until the display shows C.
Press ENTER.
Next, press the INDEX key until
UP ARROW until the display shows
Finally, press INDEX key to display

The necessary program changes are now complete. After 30 seconds the display will switch
back to the temperature reading. If you want to return faster, press the UP ARROW and ENTER
keys (at the same time) and then press the DOWN ARROW and INDEX keys ( again at the same
time). This will 'back out' of the menu and immediately display the temperature reading.

INSTALLATION
Mount the instrument in a location that will not be subject to excessive temperature, shock,
or vibration. All models are designed for mounting in an
enclosed panel.
Select the position desired for the instrument on the panel.
If more than one instrument is required, only two units can
be mounted closely together, either one above the other or
side by side. When mounted together, the mounting collar
will require modification by removing the inside tab from
each collar.
Prepare the panel by cutting
and deburring the required
opening.
From the front of the panel,
slide the housing through the
cut out. The housing gasket
should be against the housing
flange before installing.
From the rear of the panel slide
the mounting collar over the housing. Hold the housing with one
hand and using the other hand,
push the collar evenly against the
panel until the spring loops are
slightly compressed. The ratchets will hold the mounting collar
and housing in place.
INPUT WIRING
Do not run thermocouple or other input wiring in the same conduit as power leads. Use only the type
of thermocouple or RTD probe for which the control has been programmed. See the "
MENU
" to change between RTD and thermocouple input types.
For thermocouple input always use extension leads of the same type designated for your thermocouple.

The 1500 Series controls have one display. The display must occasionally switch to show
a complete message or menu item and its value. The normal display shows just the
temperature and does not switch. While showing a menu item, the display will alternate
between the menu item and the item value. If the UP arrow, DOWN arrow, or ENTER keys
are pressed, the display immediately switches to display the item value.
Key functions are as follows:
1. INDEX: Pressing the INDEX key advances the display to the next menu item. May
also be used in conjunction with other keys as noted below.
2 UP ARROW: Increments a value, changes a menu item, or selects the item to ON.
The maximum value obtainable is 9999 or 999.9.
3. DOWN ARROW: Decrements a value, changes a menu item, or selects the item to
OFF. The minimum value obtainable is -1999 or -199.9.
4. ENTER: Pressing ENTER stores the value or the item changed. If not pressed, the
previously stored value or item will be retained. The display will flash once when
ENTER is pressed.
5. UP ARROW & ENTER: Pressing these keys simultaneously brings up the
SECONDARY MENU starting at the alarm, tune, or cycle item (depending on
programming). Pressing these keys for 5 seconds will bring up the SECURE MENU.
