Operating Instructions    RTCSmp Built-In Temperature Controlled Hold-Line 
Part # 4532286 Rev 3 (6/10/14)    23 
6.3.2  Set and Current Temperatures 
Set the desired temperature by turning the control knob and the unit is immediately ready for operation. You 
can adjust the temperature in an increment of 5
o
F (1
o
C), from 122-212
o
F (50-100
o
C). The digital display 
underneath the Ceran glass shows the set temperature initially and then followed by the current/actual 
temperature. 
ON-Position
Any position where 
“0”/Line is not 
pointing straight up. 
OFF-Position 
“0” / Line is pointing 
straight up. 
6.3.3  Digital Display 
Temperature followed by a dot: 
When you turn the control knob, the digital display shows the selected temperature with a dot. 
Within two (2) seconds, the display shows the actual temperature. 
Temperature followed by a blinking dot:
The blinking dot indicates the induction zone is active and the current temperature is displayed. 
This means the system has detected a pan in the heating zone and energy is being transferred 
to the pan. 
Temperature shown without a dot:
The display shows the actual temperature and the induction coil is dormant; no energy is being 
transferred from the system to the induction pan at the moment or the system cannot detect an 
induction pan. 
NOTE  Unit with more than one heat retaining plate (RTCSmp HOIN900/1350/1800): 
To maximize efficiency with minimal resources, power cycles through the heat retaining plates at set 
intervals. This means when one plate is active and the temperature is shown with a blinking dot, the other 
plates lay dormant with temperatures shown without dots. This is normal. However, ensure you are using 
proper induction pans on the plates. 
To shutdown the unit, simply turn the control knob to the OFF-position. If the ambient temperature is over 
122
o
F (50
o
C), the display shows “hot”. Otherwise, the display is off. 
6.4  No Pan No Heat 
When a temperature is chosen, the induction unit only transmits energy when a pan is placed in the heating zone. 
If you remove the pan from the heating zone, power transfer stops immediately. If the pan is put back in the 
heating zone, power is transferred to the pan again. 
Note that pan with a bottom diameter smaller than 5”(12 cm) is not detected by the system. 
After switching the unit off, there is no heat retained inside the unit. 
6.5  When Unit is Not In Use 
Best Practice: If the induction unit is not in use, ensure the control knob is in the 0 (OFF) position. 
  Switch the unit OFF if you take the cookware away for a while. This will prevent the heating process to 
start automatically and unintentionally when a pan is placed back on the heating area. If any person 
needs to use the induction unit, he/she will have to turn the unit ON intentionally.
