3.TECHNICALSPECIFICATIONS
TC-900Ri power is a control for low temperature ventilated units which automates defrosting
processes,providinggreatenergysaving.
It has two sensors, one for environment temperature and other that, mounted to the evaporator,

The fan-delay cycle starts after draining. The refrigeration output (REFR) is active, therefore the
ambienttemperatureishigh,butthefanisactivatedonlyafterthetemperatureinevaporatorislessthan
the adjusted value. This process is necessary to remove the heat that still exists in the evaporator
becauseofdefrost,preventing totransferthisheattotheambient.

It has the purpose of cycling the evaporator ventilation until the ambient temperature approaches the
desired temperature in the refrigerating installation project, preventing high temperatures and
pressuresthatcandamagethecompressor.Ifthetemperatureinevaporatorexceedtheadjustedvalue,
thefanisturnedoffandturnedonagainwithafixedhysteresisof2°Cbelowthisvalue.
This filter aims at simulating an increase of the mass of environment sensor (S1), thus increasing its
responsetime(thermalinertia).Thelargerthevalue adjusted inthisfunction,thelongest the response
timeofsensorS1.
Atypical applicationrequiring this filteris the freezerfor ice creamor frozen goods,because when the
door is opened a hot air mass reaches the sensor directly, causing the indication of the measured
temperaturetorisequicklyandthecompressortobeactivatedunnecessarilymanytimes.
The end of defrost by time (which is not desired) can happen on the following situations:
-Adjusted temperature too high
- Maximum time of defrost too short
- Detached sensor or without contact with evaporator
