General Description
The DQ15D digital temperature control is a programmable and microprocessor based device
that operates two relays for temperature control.
Features
The temperature sensor (RTD or thermocouple)
sends a signal to the DQ15D to compare to a value
preset by the user as a Set Point (SP). Set Points
LEDs are SP1 and SP2 on the front panel.
• In heating mode if the sensor signal is lower than the
SP1
Set Point value, DQ15D energizes the
SP1
relay
and its isolated contacts close.
• In cooling mode if the sensor signal is higher than the
SP2 Set Point value, DQ15D energizes SP2 relay and
its isolated contacts close.
• DQ15D has an optional Alarm Condition feature. After
you activate this feature, when the sensor signal exceeds the Alarm Set Point, DQ15D goes into an
alarm condition. In an Alarm Condition, both relays
de-energize and the screen displays a flashing AAA.
• The pow er save, night setback feature permits the use
of a second heating Set Point to
conserve energy
when required.
Installation Procedure
DQ15D is for indoor use only.
1 Unpack and inspect DQ15D
for damage upon receipt. Shipping damage claims must be made
through the freight carrier.
2
Remove rear cover and inspect DQ15D for internal
damage.
3
Remove
the Retaining Collar. Insert a flathead
screwdriver under the collar on alternating sides
while sliding the collar back.
4 Cut a 1/
4DIN
finished opening:
3.625" x 3.625" (92 mm
x 92 mm) in the desired mounting panel location.
5 Select one or more knock-outs from the three (3)
knockouts on the rear
cover
or enclosure side panels that offers the most convenient routing for external wiring.
Avoid damaging circuitry. Remove rear cover before removing knockouts with a hammer/punch.

M-34-01-06 3/31/2016 3 DQ15D/T-DQ15D Manual
6 Remove the knockouts before reattaching the rear
cover or inserting the control in the panel.
7 Insert DQ15D through the prepared opening and slide
the retaining collar over the case from the rear of the
panel.
8 Hand tighten the collar, securely tighten the two (2)
collar screws.
9 Install a suitable liquid-tight conduit fitting throug h
the knock- out opening following manufacturer instructions and install field wiring.
10 Using the Power, Heating and Cooling Relay
Wiring illustration in this chapter, install the required
input and output wires. Use National Electric Code
and local codes for determining wire sizing, insulation, terminations, etc.
Wiring
This section provides wiring notes for Power Heating/Cooling relays and Overtemperature Protection.
Overtemperature Protection
Component failure (sensors, relays, temperature controller, etc.) in a temperature controlled process can
result in damage to the product, heater over temperature, and the possibility of a fire.
To safeguard against these events, install over temperature protection. This will interrupt the heater power
supply in the event of low solution level.
Process Technology heaters include a thermal device
(Protector 1, 2, or 3) on the heater to monitor the heater’s surface temperature. When wired properly, these
devices cut the power to the heater in low solution level
conditions. In addition to thermal protection, Process
Technology requires the use of liquid level controls to
monitor the solution level and shut off the heaters prior
to an overtemperature condition occurring.
Ensure you read and adhere to all Over-temperature
protector installation instructions and warnings.
Overtemperature protection is necessary in
any system where a fault condition could produce a fire or any other hazardous condition.
Operation without thorough safety precautions
can result in equipment failure, property damage and personal injury.
La protection de surchauffe est nécessaire
dans n'importe quel système où une condition
fausse avec résultat d'une temperature haute
pourrait produire une incendie ou autre condition dangereuse. L'opération sans les précautions complètes de sécurité pourrait mener à la
défaillance de l'equipement, l'endommagement
de la propriété, ou des blessures.

Power and Relay Wiring Procedure
Unit is intended for a single power source. To complete the wiring procedure, you will need these tools
and materials:
1. #2 Phillips head screwdriver.
2. 1/8” (x-small) straight blade screwdriver.
3. Power supply wire, 18 awg minimum.
4. Relay connection wires (see state and local elec-
trical requirements for proper 65ºC wire gauge).
Referring to the “Power, Heating and Cooling Relay
Wiring (rear view of controller)” illustration above, lo-
cate and identify terminal locations for the power supply voltage, the set point relay, and the appropriate
sensor. Connect wires into their designated terminals
and tighten the retaining screw which will secure the
wire into place.
Extending Wiring
The factory supplied 1000 ohm RTD sensor can be
extended using standard electrical hookup wire (22
awg or larger). The effect of additional 22 awg sensor
wire length on control calibration is approximately 1ºF
for every 65 feet.
Note:
This does not apply to
THERMOCOUPLES.
You
MUST use specific
thermocouple wire when
extending the sensor wir e length. Use of incorrect extension wire can cause hazardous operating
conditions.

2 Wire RTD Sensor Calibration
RTD devices are precision resistors whose resistance
value varies with temperature. DQ15D measures RTD
resistance and compares that value with a standard set
of values stored in memory. You can restore, update or
verify that this standard set of values is correct.
Equipment needed
Two
precision
resistors (tolerance
+/- 0.1% or better)
with a fixed value equal to the RTD nominal value
(i.e. 1000 ohms).
A suitable jumper cable to
facilitate changing
input
resistance.
Calibration Procedure
1 Turn OFF all power.
2 Remove rear cover.
3 Ensure the 2 wire, 1000 ohm RTD sensor is con-
nected across terminals #1 AND #2 of the terminal
block before beginning.
4 Remove RTD sensor.

3 Wire RTD Sensor Calibration
Optional input boards, Item # 5447 or 5416 needed. This board will accept 2 wire RTDs as well. RTD
devices are precision resistors whose resistance value varies with temperature. The connection of a third
wire eliminates the natural resistance of the lead
wires to improve sensor accuracy. The DQ15D control measures the RTD resistance (and the third wire
resistance) and compares that measurement with a
standard set
of values stored in the memory.
You can restore, update or verify that the standard se t of
values is correct.
Note: For a 1000 ohm sensor, the DIP switches should be OFF, OFF, OFF. For 100 ohm, ensure
the DIP switches are ON, OFF, OFF. See Dip
Switch Settings in Configuration (Setup).

4-20 mA Output (“-M” Option)
The DQ15D is available with an optional 4-20 mA
output signal
proportional to the measured (displayed)
temperature. This option is useful for source transmitting the
measured temperature to a current loopsensing device such as a PLC, remote intelligent display or chart recorder. Use Terminals #2 and #3 for 2
wire 1000 ohm RTD.
Factory calibration is verified using an intelligent NIST
traceable 4 digit DMM, a NIST traceable sensor calibrator, and an intelligent display.
The factory range setting is 0-500° F vs. 4-20 mA.
Custom ranges can be accommodated if specified at
time of order. Field calibration can use a similar arrangement or a 4-20 mA calibrator for verification.
Since calibration is an involved operation, it is suggested that it be performed only after determining that
the measured values differ from factory settings, or if
the output range is to be altered.
Use Terminals #2 and #3 for 2 wire
1000ohm RTD.
Equipment needed:
• Item #5416 or 5419 board.
• An NIS T traceable sensor simulator (calibrator
),
a precision
20
mA or higher calibrator/tester, or a
precision DMM for ver
ificat
ion
.
Calibration procedures require the removal of
the rear cover of the
control.
It also requires that
power is ON, exposing the technician to potentially lethal
voltages.

Fahrenheit: <-40° F or >+1000° F
Calibration
Error Messages
If calibration or setup information stored in the memory
becomes corrupt or erased, DQ15D switches to its
default calibration and setup settings. A flashing letter
c displays on the left side when DQ15D switches to
default sett
ings. The size and position of the letter c
will define the exact nature of the problem.
c A small c in the upper left-hand corner indicates
the control is relying on default (factory set) calibration values. This happens when the control is new
and has not yet been calibrated (setup).
c A small c in the lower left hand corner indicates the
control is relying on default configuration values.
This is a rare condition, but may occur if the control has been calibrated for use with a two-wire
RTD sensor but the configuration parameters have
not been changed from their default values.
Changing any of the configuration or Set Point variables will turn off this indication.
C A large C on the left side of the display indicates
default values are being used for the configuration
and the calibration. This can occur in a new control
that has never been calibrated or configured, or if
the memory has been erased.
RTD Error Messages
If the screen displays one of the following messages,
the control relay de-energized due to an RTD condition.
HHH A thermocouple or RTD sensor is improperly connected, or the control read an open circuit.
UUU The RTD sensor shorted.
Note:
This does not apply to
THERMOCOUPLES. A
thermocouple short causes a new junction/measurement
point to be created. This will lead to false readings and
dangerous operating conditions. Shorted thermocouples
will not result in an error condition. Instead, incorrect readings will be displayed.

M-34-01-06 3/31/2016 16 DQ15D/T-DQ15D Manual
U2, Signal Offset
This setting, which may be any number from -9 to +9, represents an offset value which is applied to the signal
received from the sensor. The units (ºC, ºF, ohms, etc.) will be dictated by the type of sensor selected in “U1” settings.
Temperature Sensor Number represents degrees Celsius or Fahrenheit as
determined by the “F5” setting
Voltage Sensor Number represents tenths of a volt (0.1 VDC)
Current Sensor Number represents hundredths of milliamps (0.01 mA)
Resistance Signal Devices Number represents ohms.
Frequency Signal Devices This setting will have no effect.
U3, Output Signal Offset
U3 adjusts the optional 4-20 mA process value output. It can be any number
from -9 to +9 and is added to the signal
level to cause the value to be rounded in an intelligent receiving device. This does not affect display value.
This function requires either the optional 5416 or 5419 sensor boards.
The default and minimum for the parameter is one (1).
Temperature Sensor: Number represents degrees C or F as determined by F5 setting
Voltage Sensor: Number represents tenths of a Volt (0.1 VDC)
Current Sensor: Number represents hundredths of milliamps (0.01 mA)
Resistance Signal Devices: Number represents ohms.
Frequency Signal Devices: Setting represents hertz (counts/second).
U4,
Signal
Filte
r
This setting, which may be any number from 1 to 64, represents the number of samples taken from the
sensor and maintained in memory. These samples are then averaged to provide an active filter of the signal.
Using a small value for this setting will cause the DE20 control to respond more quickly to sudden changes in
the sensor signal level, but this also causes the unit to be more susceptible to EMI/RFI noise. As this value is
increased, the susceptibility to inference is reduced.
The default value for this setting is four (4).
Note: When sensing temperature with a 100 ohm RTD (2 or 3 wire), set this value to twenty (20) to reduce
control error.
When sensing frequency signal, this setting establishes the time period for the controller to wait for a pulse signal. Use two (2) for this value when measuring frequency. This causes the control to measure frequencies as
low as 1 hertz while updating the display once every two seconds.
U5, SP1 Dead Band
This setting, which may be any number from 1 to +99 represents a dead band that only applies to the SP1
SET
POINT.
This is the heat Set Point.
The default and minimum for the setting is one (1).
Temperature Sensor: Number represents degrees C or F as determined by F5 setting
Voltage Sensor: Number represents tenths of a Volt (0.1 VDC)
Current Sensor: Number represents hundredths of milliamps (0.01 mA)
Resistance Signal Devices: Number represents ohms.
Frequency Signal Devices: Setting represents hertz (counts/second)
This bandwidth applies to the low side of the SP1 SET POINT. If the U5 setting is set at 5° F and the SP1 SET
POINT is set at 115° F, then the Set Point relay is de- energized when the (displayed) temperature reaches 115° F
and it is reenergized when the temperature falls to 110° F.
M-34-01-06 3/31/2016 17 DQ15D/T-DQ15D Manual
U6, SP2 Dead Band
This setting, which may be any number from 1 to +99 represents a dead band that only applies to the SP2
SET
POINT.
This is the cool Set Point.
The default and minimum for the setting is one (1).
Temperature Sensor: Number represents degrees C or F as determined by F5 setting
Voltage Sensor: Number represents tenths of a Volt (0.1 VDC)
Current Sensor: Number represents hundredths of milliamps (0.01 mA)
Resistance Signal Devices: Number represents ohms.
Frequency Signal Devices: Setting represents hertz (counts/second)
This bandwidth applies to the high side of the
SP2 SET POINT.
If the U6 setting is set at 5° F and the SP2
SET
POINT is set at 115° F, then the Set Point relay is de-energized when the (displayed) temperature reaches
115° F and will remain de-energized until the temperature increases to 120° F.
U7, Power Save Set Point Dead Band
This setting, which may be any number from 1 to +99, represents a dead band that only applies to the Power
Save SET POINT.
Temperature Sensor: Number represents degrees C or F as determined by F5 setting
Voltage Sensor: Number represents tenths of a Volt (0.1 VDC)
Current Sensor: Number represents hundredths of milliamps (0.01 mA)
Resistance Signal Devices: Number represents ohms.
Frequency Signal Devices: Setting represents hertz (counts/second)
If the Power Save SET POINT dead band setting is set at 10° F and th
e Powe
r Save SET POINT is 75°F, the SP1
relay de-energizes when the temperature reaches 75° F and reenergizes when the temperature falls to 65°F.
U8, Display Stabilizer
If the display value changes by a digit or two in a steady state condition, this setting can be altered in conjunction with the U4 setting to reduce the display instability. Lower values cause maximum suppression. Larger
values provide greater accuracy.
The default value for the U8, Display Stabilizer setting is ten (10).
L, Set Point Limit
This setting, which may be any number bet ween -99 and +999, is the maximum limit for all
SET POINTS
except
the ALARM
SET POINT.
This will prevent accidental setting of a Set Point, which could be too high or low (de-
pending upon the application).
Temperature Sensor: Number represents degrees C or F as determined by F5 setting
Voltage Sensor: Number represents tenths of a Volt (0.1 VDC)
Current Sensor: Number represents hundredths of milliamps (0.01 mA)
Resistance Signal Devices: Number represents ohms.
Frequency Signal Devices: Setting represents hertz (counts/second)
The default value for this setting is +999.

F1, SP2 and U7 Disable
This setting may be either a one (1) or a zero (0), and controls the behavior of the DQ15D by making it perform like the single Set Point PROCESS TECHNOLOGY model DE control. When this setting is set to one (1),
it is ON. The SP2 Set Point and the U7 Power Save Set Point are both disabled and will not work.
F2, Heating or Cooling Switch
Not available.
F3, Alarm On/Off
Switch
This setting may be a zero (0) or a one (1). When set to zero, the alarm set point is turned off. When set to one,
alarm set point is turned on.
Note: The default value for this setting is zero (0).
F4, Unit Display Enable Flag
This setting may be set to a zero (0) or a one (1). When set to one (1), the DE20 will display either a “C” or an
“F”, separated by a decimal point. This indicates that either Celsius or Fahrenheit is being displayed. If the tem-
perature being measured is greater than +999 degrees, the units are not shown because the display is limited
to four positions.
F5, Temperature Units Conversion
This setting may be set to a zero (0) or a one (1). When set to a zero (0), the temperature is displayed in
degrees Fahrenheit. When set to a one (1), the temperature is displayed in degrees Celsius.
Conversion from F to C does NOT change set point or alarm upper limit values. These must be changed
manually.
Note: The default setting is zero (0).
F6, Current Output Enable Flag
This setting can be either zero (0), which is OFF, or one (1), which is ON. When ON, it enables the optional
current adder board on the DQ15D. See
4-20 mA Output Option for details on the current output signal.
If the DQ15D is equipped with the optional 4-10 mA output feature, then setting F6 to one (1) turns ON this
feature. F6 must be ON before any calibration can be performed.
The default setting is zero (0). Only active when using the optional 5416 board.

Electrical Noise and Interference
Process Technology electronic controls are engineered, tested and manufactured to conform to Europe’s CE
levels of electrical noise and interference found in typical industrial installations. It is always possible for
electrical noise and interference to exceed the level of designed-in protection. This can happen, for example, if
arc or spot-welding equipment is close to the control or if they share a common power line. It can occur if
flame ignition systems or electrostatic precipitators are in the vicinity of the control. A more common source of
interference occurs when the control is switching inductive loads such as contactor coils, solenoids or motors.
The collapse of the magnetic field when loads such as these are switched off can create an electrical “spike”
that can cause a malfunction of the microprocessor used in the control. Even if the control doing the switching
is unaffected, a nearby control may be affected. To eliminate or minimize this problem, transient suppressors
or “snubbers” can be employed across the inductive load.
