INSTALLATION AND

OPERATION INSTRUCTIONS

FAILURE TO READ AND FOLLOW ALL INSTRUCTIONS CAREFULLY
BEFORE INSTALLING OR OPERATING THIS CONTROL COULD CAUSE
PERSONAL INJURY AND/OR PROPERTY DAMAGE.

DESCRIPTION

The 16E09-201 is a single stage electronic temperature con­trol, 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 tempera­ture 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 walk­in freezers, beverage coolers, supermarket display cases
for flowers, produce, meats, convenience store refrigerated
cases, food warmers, boiler control, and certain industrial
applications.

INSTALLATION

To prevent electrical shock and/or equipment dam-

age, disconnect electric power to system at main
fuse or circuit breaker box prior to installation or
service.

Where failure of this control may result in personal

injury and/or property damage, additional alarms or
limit controls must be installed.

This control is a temperature control and is not to

be used as a temperature limit control.

Fig. 1 Control Front View and Description

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".

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

Selects how the set point temperature will operate the load
terminal. CI indicates the setpoint temperature will be the
Cut In temperature. CO indicates the temperature will be the
Cut Out temperature. See Operation section.

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.
