L6008A Location Differential Calibration
The L6008A1093 is calibrated for applications where the 
bulb and controller case are located in the same control 
space.
 If the bulb and controller case are located in separate 
rooms, and if the temperature in the two rooms is different, 
an adjustment is required. Adjust the dial setting (control 
space temperature setting) to compensate for the differ-
ence in temperature.

1. If the L6008A case is located in a room with a highern 

temperature than indicated on the dial setting, raise the 
dial setting the number of degrees listed in Table 3.

2. If the L6008A case is located in a room with a lower 

temperature than indicated on the dial setting, lower the 
dial setting the number of degrees listed in Table 3.

EXAMPLE:
In the example shown in Fig. 33, the L6008A case is located 
in a room with a lower temperature than the controlled 
space. Adjusting the controlled space setting (dial setting) is 
necessary to compensate for the temperature difference of 
35° F (20° C) between the two rooms. Table 3 indicates that 
the dial setting should be lowered 5° F (3° C) to compensate 
for the 35° F (20° C) temperature difference.

Manual Reset
If the device includes manual reset (L4006E, L4008E), 
be sure to press the (red) reset button on the front of 
the case to make sure that the controller is not locked 
out on safety. When checking the system, adjust the limit 
setting low enough so the temperature of the controlled 
medium reaches the high limit setting. When the limit set-
ting is reached, the Aquastat Controller locks out and the 
burner shuts down. When the temperature of the controlled 
medium drops to the high limitsetting, less the differential, 
push the manual reset button to make the system operative 
again. Reset the control to the proper high limit setting.
