12 MAINTENANCE (continued) Display Codes (DCH-320) This section describes the different display codes and their meanings. LO flashes during the initial warm up period. The unit continues to display this code until the unit reaches the setpoint temperature. When the unit reaches the setpoint temperature, it displays the setpoint temperature. O F O C This figure shows an example setpoint temperature of 200 F displayed on the console. TEMP UP TEMP DOWN TEMP SCALE HI flashes if the actual cabinet temperature exceeds the setpoint temperature or if the thermistor has shorted. NOTE: The thermistor should be 100k ohm +/- 2% at room temperature. OPEN flashes if the thermistor is OPEN or disconnected. The unit will not call for heat. NOTE: The thermistor should be 100k ohms +/- 2% at room temperature. PO In 120 VAC units, this code flashes if the supply voltage is below 100 VAC or above 135 VAC. In 220/ 240 VAC units, this code flashes if the supply voltage is below 190 VAC or above 265 VAC. NOTE: If voltage is within normal ranges, then the Control Board is faulty. To reset a unit in this state, the supply voltage must be within acceptable limits and the unit must be turned off for a few seconds and then turned back on. 12

13 Operations and Programming MAINTENANCE (continued) IMPORTANT: DCH-320 models have a temperature range of F (38-74 C) which is below the safe holding temperature for some foods. Only non-potentially hazardous food should be held in these units. NOTE: The Setpoint temperature is the desired temperature setting. The Indicated temperature is the actual temperature inside the cabinet.
