SYSTEM OVERVIEW
The basic principle of the Fermentation Temperature Stabilization System (FTSs
2
) is to pump chilled
water or glycol through the immersion coil when the temperature of your wort is greater than the controller
set-point. The system is designed to use chilled ice water from a common cooler or glycol chiller. In this
configuration, the submersible pump will be placed in the bottom of the cooler.
The FTSs
2
is intended to be a low pressure closed loop system. Water or glycol pumped from the cooler
to the fermenter is then returned to the cooler to be used again.
If your setup requires more distance from the fermenter to the cooler, you can purchase common vinyl
tubing at most hardware stores. The pump is capable lifting the water up to 10 feet. Pumping beyond
10 feet will negatively affect efficiency.
In a heating mode, the controller will activate the low wattage heater, which will in-turn begin to slowly
raise the temperature of the liquid volume starting at the fermenter’s cone. From there, convection will
foster the newly introduced heat to radiate up to the remaining liquid volume not in direct contact with
the cone. This key characteristic insures that hot-spots don’t form within the fermenter.

SANITATION
FIRST TIME CLEANING
Sanitize the immersion coil, thermowell, lid and gasket.
Before you use your system, you will need to clean all manufacturing residues with either TSP (highly
recommended and can be found at any hardware store) or warm soapy water, followed by a good hot
water rinse. Please see the FAQ section on our website (www.ssbrewtech.com) regarding proper care
and cleaning of stainless steel.
PRE-ASSEMBLY INSTRUCTIONS
NOTES ON EFFICIENCY
Efficiency of your system depends on many variables. Ideally, you would have the fermenter in an area
where the temperatures are relatively moderate.
Since the system contains both heating and cooling, the controller will need to be properly setup to
avoid over cycling. Cycling is where the system runs the cooling or heating cycle long enough to over-
shoot the set point and past the threshold where it causes the opposite function to activate too quickly.
To avoid over cycling, we recommend you set the “delay” on your controller to at least 5 minutes. This
will allow sufficient time for the fermenter’s liquid temperature to stabilize and ultimately avoid over
cycling.
This will extend the life of the ice in your cooler. We recommend using ONLY block ice, frozen plastic
water jugs or similar. Cubed ice melts much faster than block ice thus requiring more frequent additions
of ice to ensure you maintain cold water. You should avoid using your FTSs
2
to bring the wort from a high
temperature to a pitching temperature. In addition to leaving all of the cold break* in your fermenter, it
will consume much of your cooling capacity and require you to replenish the ice early in the process.
*Cold break- A term that describes the precipitation or flocculation of proteins, tannins, and hop matter
that occurs when wort is rapidly chilled.

BEFORE YOU BREW - SYSTEM ASSEMBLY
1.
Think about where you want to locate your Brew Bucket or Chronical series fermenter, where you will
place the controller, and where you will place your chilled water source (whether that is an ice chest,
chilled corny keg in a cooler, glycol chiller, etc.).
2.
Start by removing your fermenter’s fittings, lid, and neoprene jacket if it is already installed, and then
place the fermenter upside down on a surface that won’t mar the upper rim of the body. This will make
it easier to insure the heater is orientated correctly on the cone while you reinstall the neoprene jacket.
3.
Place the low-wattage heater onto the cone so that it doesn’t interfere with the welded fittings, and
maximizes surface area contact with the fermenter body. Use a zip-tie to hold the heater’s shape until
the neoprene insulating jacket is reinstalled over the fermenter. The neoprene jacket will insure that the
heater is held tightly to the cone to maximize efficiency.
3.
Extend the wire from the low-wattage cone heater out of the bottom of the neoprene jacket.
4.
Next, install the immersion coil and thermowell into the lid as shown (Note: there are extra o-rings
supplied; you only need to use the o-rings on the wort side of the lid).

Divide the piece of vinyl tubing into two equal lengths. Connect one end of one tube to the immersion
pump outlet and secure it with a hose clamp. The pump outlet is the small pipe connection on the top
side of the pump. Connect the other end of the same piece of tubing to the immersion coil and secure
it with a second hose clamp. Take the remaining piece of tubing and connect it to the other end of the
immersion coil and secure it with a third hose clamp and then place the free end of the tubing back into
the cooler.

OPERATING INSTRUCTIONS
INSTALLING THE FTSs
2
SYSTEM
1.
Sanitize your Brew Bucket or Chronical fermenter.
2.
Fill your Brew Bucket or Chronical with cooled wort.
3.
Place the sanitized FTSs
2
lid onto your Brew Bucket or Chronical fermenter.
4.
Install a sanitized airlock (bubbler) or blow-off tube.
5.
Connect the chilled water tubes to immersion coil and secure with zip ties or hose clamps.
6.
Insert the temperature sensor into the thermowell.
7.
Be sure the sensor is fully inserted to the bottom of the thermowell. (The excess wire on the
temperature sensor can be “pushed” into the body of the controller if desired).
8.
Plug the pump connector into the connector labeled “Pump”. Plug the heater connector into the
connector labled “Heater”.
9.
Plug the power supply connector into the side labeled “12VDC”.
10.
Place at least 10lbs of ice with about 2 gallons of cold water in your cooler.
11.
We recommend using three of the 1/2 gallon size frozen jugs of water or block ice, as these will last
much longer than cube ice.
12.
The chilled water needs to fully cover the pump by at least 2” of depth - add more water as needed.
Generally, you should have about 50% of your fermentation volume in chilled water (for a 5 gallon batch
of beer, use about 2 1/2 gallons of chilled water).
13.
Plug the power supply into a wall outlet (110V – 240V).

FAQs
Q – Can I control more than one fermenter with a single FTSs
2
control unit?
A – You can, but it’s better to use individual controllers, one for each fermenter because fermentation
will progress at different rates.
Q – Can I use a single source of chilled water for multiple fermenters?
A – Yes, but keep in mind the thermal load will be doubled with 2 fermenters, so you will need twice the
cooling capability for your chilled water.
Q – Can I increase the efficiency of the FTSs
2
system?
A – Yes, there are several things to consider: Most important, your initial wort temperature should be at
or slightly below the set point temperature. Otherwise your chilled water will be consumed to cool the
wort before fermentation starts. Use block ice or frozen water jugs as opposed to ice cubes. Ferment
in an area with as moderate of an ambient temperature as possible. Use a cooler with thick walls and
a good insulation value. Insulate the hoses going to the immersion chiller.
Q – Can I use the FTSs
2
to cool the wort to pitching temperatures?
A – Yes, but after you get to pitching temperatures, you should replenish your ice supply.
Q – Can I set multiple temperatures during fermentation, say 72°F for the lag phase and 68°F for
primary?
A – Yes, however you will need to watch the progress of your fermentation closely so you don’t stay too
long at a higher temperature than you planned.
Q – How often do I need to replenish my ice?
A – That depends an many variables, so there’s no exact answer. However, you should check your ice
daily until you get a feel for the ice consumption on your particular fermentation setup.
Q – Can I run glycol in the FTSs
2
?
A – Yes, the submersion pump will operate fine in glycol, but this assumes you have a method to cool
the glycol.
Q – My FTSs
2
seems to over-shoot the set point, is there a problem?
A – No, the FTSs
2
will stop running when the set point is reached, however the immersion coil is colder
than the surrounding wort.
Q – Can I use my refrigerator for the chilled water?
A – Yes, as along as the chilled water temperature is at least 15ºF below the set point, it will work fine,
although it will cycle more often and for longer periods. Ideally, the chilled water volume should be equal
to your fermenting volume.
