3.6. FUEL OIL MODE
The Fuel Oil control mode prompts you to enter the control parameters for a Fuel Oil Flow
Maintenance application. In this mode, you will be given three different control method options:
Ambient, Line, or PASC.
3.6.1.
TEMP CONTROL – AMBIENT CONTROL
Fig. 3.45
Fuel Oil Temperature Ambient Control window
The Temp Control window allows you to select the temperature control mode to Ambient Control,
Line Control or PASC. This option depends on where the controlling RTD inputs are situated and
utilized: either measuring the temperature of the environment surrounding the pipe (ambient), or
directly on the pipe itself (line). Tap Ambient.

Maintain Temperature:
THE SETPOINT TEMPERATURE IS THE DESIRED MAINTAIN
TEMPERATURE FOR THE PIPE.
Based on the measured control temperature, the ACS-PCM2-5, or C910-485, will switch the relay
output to maintain the system at the desired setpoint.
Range:
35°F (2°C)–50°F (10°C)
Default:
40ºF (4°C)
If the 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:
1ºF (1°C)–10ºF (6ºC)
Default:
5ºF (3ºC)
