To locate a controller, search on the part number such as 965A-1CD0-00RG. Use the Help feature in Adobe Reader on
how to search documents.
If there are multiple listings, then the retrofit is conditional upon field use. Select the appropriate selection. The User’s
Manual is included at the bottom of this document when availab le.
Before selecting a replacement controller:
1. Know the application.
• Temperature range
• Sensor type
• Is the sensor upgradable if required?
• Additional input requirements – remote set points, secondary sensor or events
• Output required – control, alarm, event
• Is the power-switching device upgradable?
• Operating voltage of controller
• Mounting requirements – panel space
• Is a safety limit device required?
2. Know the product.
• Inputs – type and number of
• Control function – direct (cool) or reverse (heat )
• Outputs – switched DC, SSR, or mechanical relay
• Communication requirements
• Which control features are required? (cascade, slidewire, differential, remote control, other)
3. Use your best judgment for selecting a replacement controller. All applications require close examination of input,
output and the control mode needs to have the controller function properly.
4. Safety: Remember to make sure all redundant safety equipment is in place and working when retrofitting equipment.
If a system has been retrofitted without the proper safety equipment, you could be liable if an accident occurs.
This is only a guide to replacement controllers. If you have doubts, please call (507) 454-5300
and ask for technical support or email wintechsupport@watlow.com. We’re here to help. The
suggested replacement will differ in fit and form. Please review the replacement controller
specifications for suitability. Carefully check the notes for additional information that may
apply.

¼ DIN – Deutsche Industrial Norm standard for panel mounted controller, hole size is cut to 3.63”w x 3.63”h.
Action – determines the direction of control. Heat (reverse acting) or Cool (direct acting).
Auto Reset – the limit will automatically reset on a power cycle but requires manual reset on limit trip.
Cascade – a control algorithm in which the output of one control loop provides a set point for another loop. The second
loop, in turn, determines the control action.
Ch – Channel refers to an analog input. There are single and dual channel controllers.
Control Mode – the method that a controller uses to switch the outputs such as PID, ON/OFF, and Manual.
Differential - control algorithm in which the output is based on the difference of the inputs plus set point.
DIN – Deutsche Industrial Norm, a set of technical, scientific and dimensional standards developed in Germany. RTD
sensors with the DIN curve change resistance at a rate of 0.00385 ohms/ohms/C.
DIN Rail – standard DIN EN50022 mounting method for attaching devices onto a metal rail.
Fixed – refers to a set point that is fixed at one value.
High Limit - device will deactivate output on a temperature rise above set point.
Inductive Load – any device that has a wire winding such as solenoids, electromechanical relays or transformers.
Input – refers to the sensor types that may be connected.
Integral – the set point in integral (on board) to the controller.
JIS – Joint Industrial Standards, a set of technical, scientific and dimensional standards developed in Japan. RTD sensors
with the JIS curve change resistance at a rate of 0.00396 ohms/ohms/C.
Line Voltage – the voltage required powering the electronics of the controller.
Low Limit - device will deactivate output on a temperature drop below set point.
On/Off – a method of control that turns the output full on until set point is reached and then off until the process error
exceeds the hysteresis.
Open Brd – the form factor of this controller is an open circuit board mounted on four standoffs.
Manual Reset – the limit must be reset on a power cycle and requires manual reset on limit trip.
Multi RSP – multiple remote set potentiometers were supported. Each allowed the set point to be selected and adjusted.
Relay – refers to an electromechanical relay.
Remote – set point is adjusted using a remote potentiometer.
Panel – the form factor of this controller is mounted through a hole cut in the panel.
PI – Proportional and Integral, a control mode with two functions: proportional action dampens the systems response,
and integral corrects for droop.
PID – Proportional, Integral, and Derivative, a control mode with three functions: proportional action dampens the
systems response, integral corrects for droop, and derivative prevents overshoot and undershoot.
Potted – the circuit board and electronics are encased in epoxy.
Proc – Process input may accept 0-5, 1-5, 0-10 volts or 0-20 and 4-20 mA.

Sw DC – Switched DC, a time proportioning DC output used to drive DC input solid state relays.
t/c – Thermocouple sensor device made by joining two dissimilar metals whose standards is identified by a letter.
Temp Range – the range over which the controller could have the set point adjustment.
Thermistor – a sensor that changes resistance as the temperature changes. Similar but not the same as an RTD.
Universal – Input can be a thermocouple, 100 ohm DIN RTD or process (volts or milliamperes)
VAC – Volts Alternating Current
VAC/DC- Volts Alternating Current or Direct Current
VDC – Volts Direct Current
VTB Sw DC – Variable Time Base Switched Direct Current, a time proportioning DC output where the cycle time is
variable.
These notes are used to signify areas of concern in changing to a retrofit choice. These notes are also printed at the end
of the retrofit listing.
Note 1: Retrofit controller requires a substitution of a 100 Ohm RTD sensor for the thermistor.
Note 2: Mounting and dimensions of retrofit controller are different. Verify that sufficient panel space and depth is
available.
Note 3: Retrofit controller outputs are different. Add external interposing mechanical or solid state relay if applicable.
Note 4: Retrofit controller has a programmable, not fixed set point. Lock set point using controller's lockout parameter.
Note 5: For DIN rail mounting or sub-panel mounting, purchase DIN rail adapter p/n 0822-0586-P001 for 1/32 DIN or
p/n 0822-0586-P002 for 1/16 DIN.
Note 6: Add a suppressor, Watlow p/n 0804-0147-0000, for inductive loads.
Note 7: Retrofit does not have equivalent action (as example, no manual reset)
Note 8: Retrofit controller does not have dual dial scale.
Note 9: Hardware lockout is not available on retrofit.
Note 10:Retrofit controller does not have user selectable line voltage.
Note 11:Retrofit does not support remote set point or retransmit. Check if pins 13, 14, 15 or 16 have termination. If
wires are on these pins, select a different retrofit.
Note 12:Retrofit co ntroller does not have user selectable control action.
Note 13:Solid state sensor required for humidity. See http://www.vaisala.com
Note 14:Retrofit co ntroller does not have user selectable control mode.
Note 15:Use auxiliary event board A007-1732-F4B8
Note 16:Retrofit communications are different, consult specifications.
Note 17:Verify retrofit input range matches application.
