29. D INDEXES CONTROL MODE DEFINITIONS On Off The NGC 20 monitors the control temperature and compares it to the setpoint If the control temperature is above the setpoint by more than the Deadband value the relay output is turned off If the control temperature falls below the setpoint temperature the output is turned on The control temperature is defined as the lowest RTD temperature input value Additional Entry Fields Deadband Ifthe control temperature is above the Setpoint temperature plus Deadband the relay output is turned off If the control temperature is below the Setpoint temperature the output is turned on Range 1 C 2 F to 50 C 90 C Default 3 C 5 F PASC Proportional Ambient Sensing Control PASC takes advantage of the fact that the heat loss from a pipe is proportional to the temperature difference between the pipe and the ambient air This is true regardless of heater type insulation type or pipe size Once the heat tracing and insulation on a pipe has been designed to balance heat input with heat loss and maintain a particular temperature the main variable in controlling the pipe temperature becomes the ambient air temperature The NGC 20 has a control algorithm that uses the measured ambient temperature desired maintain temperature minimum ambient temperature assumption used during design and size of the smallest pipe diameter to calculate how long the heater should be on or off to maintain a near constan
