INSTALLATION AND
OPERATION INSTRUCTIONS
DESCRIPTION
The 16E09-101 is a single stage electronic temperature con-
trol, with a Nema 1 rated enclosure, and can be used for most
applications within the temperature control range of -40° to
220°F, (-40° to 104°C). The control has an SPDT (Single Pole
Double Throw) output load relay.
The control has user options to control differential, anti-short
cycle delay, set back, offset, alarms and more. It includes an
NTC (Negative Temperature Coefficient) thermistor tempera-
ture sensor, and can be used with certain other NTC or PTC
(Positive Temperature Coefficient) thermistors that meet the
specified resistance vs. temperature specifications. See the
tables on page 7.
The control can fit many applications, which range from
refrigeration to heating due to the wide temperature range of
the control stated above. Typical applications include walk-
in freezers, beverage coolers, supermarket display cases
for flowers, produce, meats, convenience store refrigerated
cases, food warmers, boiler control, and certain industrial
applications.

The control has a user selection for changing the setpoint to
be either the Cut In or the Cut Out setting. The user must be
careful to understand how this effects the “range” in which
the control will operate when the differential value is entered.
If entered values are incorrect, the control could operate
outside the user’s intended settings due to set-up error. See
section titled "Operation".

INSTALLATION
NOTE:
Green Status Indicator LED and display backlight operation
It may be observed from time to time that the green status indicator LED and
display back-light will briefly turn off during a call for heating or cooling. During this
time, the control is performing a self-check lasting up to 15 seconds. This is normal
operation of the control and the load power will be maintained

Power Stealing
Power Stealing is an electronic design within the control that
can eliminate the need to connect a neutral line to power the
control. The control receives power from the unit it is control-
ling. Power Stealing saves time and money by often eliminat-
ing the labor to run a neutral wire to the control for power. See
compatibility chart below for certain limitations.

USER MENU OPERATION SETTINGS:
The control has user Menu settings that will determine how
the control operates. The unit is shipped with factory de-
fault settings. The user must change any of the settings as
required for the application. To reset all settings to factory
defaults, press and hold all 3 buttons simultaneously (
,
, and buttons) for approximately 5 seconds.
To view Menu items, press and hold for 5 seconds.
The unit will display the first Menu item on the left side of the
display. The right side of the display indicates the Menu item
settings. To change the setting, momentarily press the
or
key.
A momentary press of the
key advances the display to
the next Menu item, and continues, till the last menu item is
displayed. Pressing the key one more time with the last menu
item, (aL) displayed returns the control to the operating mode.
USER MENU
Each press of results in forward movement to the next
Menu item. If you need to change an item “passed”, you
must repeatedly press , return to the operating mode,
then press and hold for 5 seconds to re-enter the Menu
mode. Then repeatedly, momentarily press until the
desired Menu item is again displayed.
To store any changes made to any Menu items, the Menu
must be exited by pressing when the last item is
displayed. If no buttons are pressed for ten minutes while in
the menu, the control will return to operating mode and any
changes that were made will be lost.
The following table shows the menu items, default settings
and optional settings.
NOTE: The Heat/ Cool switch (SW1) MUST be in the proper
position BEFORE setting options.

Cooling - Selects the operation of the Control Load
relay in the event of a sensor failure in Cool mode. 1
(default) will cause the load contacts of the relay to
close and remain closed if the sensor either opens or
shorts. 0 causes the load contacts of the relay to open
and remain open.
Heating has no optional selection. Sensor failure
in Heating will result in the relay contacts opening.
dL Display Light Off On or Off Selects the LCD display light Off or On. With this
selected Off, the display light will illuminate any time a
keypad button is pressed to provide better viewing in
low lighting conditions, and go off after 10 seconds. If
On is selected, the display light will be On continuously.
ASd Anti Short-Cycle Delay Cool

0
0 to 12 Selects the minimum time (in minutes) that the load
contacts will remain open after a cycle before closing
again. This will prevent the compressor or other load
from being damaged by cycling too soon. A blinking
Snowflake or Flame icon indicates that the control has
a demand to energize the load, but is waiting for the
delay time to elapse. A setting of 0 indicates no time
and the feature is disabled. SW1 must be set to the
proper position before checking this setting.
LP Lock Front Panel Keypad Off On or Off When selected Off, the keypad can be used as normal.
When selected On, prevents unauthorized access to
the control settings by locking out all keys. To unlock
the control when it is locked, press and hold the Menu
key for 5 seconds.

This control is calibrated at the factory, but the “sensed"
temperature may read different because of mount-
ing/installation, or other factors. This item allows the
displayed temperature to be shifted the number of
degrees set to compensate for this difference

Example:
This control is a temperature control and is not to
be used as a temperature limit control.
To prevent scald injury, do not use this control to
heat water for bathing, washing, hot tub or similar
applications.
The factory default setpoint for this control is 45°F (7°C) for
Cool and 120°F (49°C) for Heat. Setpoint temperature can
be adjusted using the
or keys. A power loss does not
lose the settings. All menu item selections and setpoint set-
ting are stored in a permanent memory.
The user determines the temperature operating range. To
determine the temperature range, the user must select the
Set Point (SP) as the Cut Out or Cut In temperature, Dif-
ferential (dFF) and enter a set point temperature. Cut out
is when the load is turned off and cut in is when the load is
turned on.
NOTE: The Heat/ Cool switch (SW1) MUST be in the proper
position BEFORE setting options.

bIn Binary Input Off On or Off The default setting of Off will have no affect on the
operation of the thermostat. When set to On, it allows
an external binary input (switch or relay) to start a tem-
perature set back. See Set Back (Sb).
Sb Set Back 0 0 to 50 Selects the number of degrees the thermostat will
change the setpoint temperature when the external
binary input signal is received. 0 will cause no tempera-
ture change to occur. See Binary Input (bin).
AL Alarm 0 0 to 99 Selects the time delay (in minutes) before a Tempera-
ture Out of Range alarm output is sent.
A setting of 0 disables the alarm relay.
