Do not Connect the Controller. Directly Connect the Cooling
Device e. g. : Compressor. to the system and check the maximum
cooling it can produce. In case temperature goes to 0 deg or
-10 deg then by using a STC1000 you can control at +5 deg.
But if directly you get cooling of only upto +10 deg then it is impossible for any controller to produce extra cooling, in such a case as this use a better compressor or more insulation.
Connect Sensor properly and replace when broken keep sensor
close to the source of cooling.
Deadband (DB) at minimum is 1 Deg this is the best setting,
maximum setting of deadband may increase compressor life and
also save power but will produce a huge variation in
If large Variation of temperature is present and you need accurate control Reduce deadband to min.
Unit is factory set db at 1 deg, remove seal tape before dead
