FTSs Pro Modular Temperature Controller
Instruction Manual
INTRODUCTION
OVERVIEW
The FTSs Pro Modular Temperature Controller works in conjunction with a
pressurized glycol system to provide temperature control over the contents of
your vessel. It functions by using a temperature sensor to read the present
value (PV) of your vessel, and triggering an output based on the set value
(SV) in order to match PV with SV. When cooling is called for, the solenoid
valve will open to allow the flow of glycol through your vessel’s cooling
jackets or coils until the set value is achieved. 
SETUP
POWERING THE FTS PRO
The FTSs Pro Modular Temperature Controller comes with a lead marked “110
~240VAC-in”. The three wires in this cable correspond to hot (brown wire),
neutral (blue wire), and ground (green/yellow wire). A plug is purposely
omitted from the cable to accommodate various methods used for supplying
110~240VAC to the unit. If you are installing a plug, BE SURE that a GFCI
breaker/receptacle is installed.
SENSOR INSTALLATION
The FTSs Pro Modular Temperature Controller comes with a lead marked “Sensor”.
The two wires in this cable (red and black) will connect to your temperature
sensor. If you are using an Ss Brewtech vessel, your tank comes equipped with
a PT100 platinum resistance thermometer. The red and black wires will connect
to terminals 1 and 2 on the thermometer’s plug. The orientation of the wires
does not matter, as long as they are connected to terminals 1 and 2.
SOLENOID INSTALLATION
The FTSs Pro Modular Temperature Controller comes with either a ½” (1-3.5 bbl
Unitank) or ¾” (5 bbl and larger Unitank) electric solenoid valve.
Installation can be handled in a variety of ways based on preference and
setup. We recommend the installation of a manual bypass piping/valve
arrangement, as well as piping/valve arrangement to clear the line of glycol
in the event that service is needed.
SENSOR: SETTINGS & CALIBRATION
SETTINGS
The input setting can be manipulated based on the type of sensor being used.
The correct input setting for a PT100 sensor is “Cn-t: 1”. This should be the
default setting on your controller. If you are reading a sensor error message
(S.ERR), double-check your connections to the sensor and ensure that “Cn-t” is
set to 1. If you are using a different type of sensor, see the included chart
to determine the proper input setting for your particular sensor.
Ss Brewtech Pro Tanks ship with a PT100 type temperature sensor included. To
set the temp sensor type, begin by pressing the “Level Key” (3 or more
seconds).
Then press the “Mode Key” until you see “Cn-t”. Finally, press the “Up” or
“Down” key to select “1” for a PT100 probe. For other temp sensor options,
please reference the table on the following page.
Press and hold the “Level Key” for more than 3 seconds to return to the
primary display.
OTHER TEMP SENSOR OPTIONS
| Input type| Name| Set Value| Input Temperature Setup
Range
---|---|---|---|---
Platinum resis- tance they mometer input type| Platinum resistance
thermometer| Pt100| 0| -200 to 850 ( °C)/ -300 to 1500 ( °F)
1| -199.9 to 500.0 (°C )/ -199.9 to 900.0 (°F )
2| 0.0 to 100.0 (°C )/ 0.0 to 210.0 ( °F )
JPt100| 3| -199.9 to 500.0 (°C )/ -199.9 to 900.0 (°F)
4| 0.0 to 100.0 (°C )/ 0.0 to 210.0 ( °F )
CALIBRATION
Before use, it is important to ensure that your sensor is properly calibrated.
There are several ways of calibrating a temperature sensor, but the simplest
way is to use an ice-water mixture. When you insert your sensor into an ice-
water mixture, it should read 32°F (0°C). Perform the “ice method” of
calibration and document the offset, if any. You can then set a temperature
offset on the controller to reflect this variation.
Press the “Level Key” for less than 1 second, and then use the “Mode Key”
until you see “Cn5”. Next use the “Up” or “Down” key to change the temperature
offset.
Press the “Level Key” for less than 1 second to exit to the main screen.
ADDITIONAL MENU SETTINGS
The FTSs Pro Modular Temperature controller uses an Omron Digital Controller as the “brains of the operation”. It contains a whole host of menu options and settings that are not crucial to the basic functioning of your FTSs Pro. Outlined below are a few of the more pertinent menu settings. For more detailed information, please consult the Omron Programming Guides.
TEMPERATURE UNITS
The FTSs Pro Modular Temperature Controller allows the user to toggle between
Fahrenheit and Celsius. To do so, hold the “Level Key” for 3 or more seconds
and then press the “Mode Key” until you see “d-U”. Press the “Up” or “Down”
Keys to toggle between Fahrenheit (F) and Celsius (C). 
HYSTERESIS
The FTSs Pro Modular Temperature Controller allows you to set a hysteresis
value. This value represents the number of degrees away from the set value
that the Omron will trigger an output. Press the “Level Key” for 3 or more
seconds and then press the “Mode Key” until you see “HYS”. Press the “Up” or
“Down” Keys to adjust the value.
For example, if the hysteresis is set to “1” (default setting), then the
solenoid valve will only open when the PV is one degree or greater above the
SV. We recommend leaving this value at “1” to prevent over-cycling of the
system.
DECIMAL POINTS
The controller can be set to adjust the decimal point displayed on the
controller. This is handy if you wish to have finer temperature control, or if
you are using a smaller hysteresis value. Press and hold the “Level Key” for
less than 1 second and then press the “Mode Key” until you see “do”. Use the
“Up” or “Down” Keys to move the decimal points. Press the “Level Key” for less
than 1 second to exit. 
OPERATIONS
RUN
When in “Run” mode, the user can select a set value using the up and down
keys. This can be used to maintain fermentation temperatures, or for cooling
purposes. When the set value is below the present value, “OUT” will display on
the controller and the solenoid valve will open. When the set value is
achieved, “OUT” will disappear from the display and the solenoid valve will
close.
CRASH
When in “Crash” mode, the user can quickly toggle to a programmable “crash”
temperature (0°C, for example). The controller will memorize this temperature,
and by simply turning the switch you can switch to this temperature without
toggling the up and down keys.
