3. ELECTRONIC CONTROLS
[a] SET POINT TEMPERATURE (compressor OFF
temperature)
Off-cycle defrost (RTC series): -2 to +12°C
Heater defrost (FTC series): -23 to -7°C
[b] CABINET TEMPERATURE DIFFERENTIAL
4 K (from “set point temp” to “set point temp + 4 K”)
The compressor stops when the cabinet temperature reaches down to the set point
temperature, and starts when the cabinet temperature rises to the set point tempe
4°C. Accordingly, the average cabinet temperature will be around the set point temperature
+ 2°C.
[c] DEFROST CYCLE
The unit automatically defrosts the evaporator 3 hours (RTC series) or 6 hours (FTC
series) after the refrigeration starts. The defrost indicator light on the operation panel
comes on when the defrost cycle starts.
[d] DEFROST TERMINATION TEMPERATURE
Off-cycle defrost (RTC series): +5°C
Heater defrost (FTC series): +20°C
[e] TEMPERATURE DISPLAY
During a defrost cycle, the screen indicates “dF” (FTC series only).
