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 efciency 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 ne 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 ne,
although it will cycle more often and for longer periods. Ideally, the chilled water volume should be equal
to your fermenting volume.
