If a refill setting other than Disabled is selected, the user
must set at least two level sensor locations as installed
by checking the check box on the screen. If all three
locations are set to installed, the system will default to
the Auto-Top Off refill setting and operate as follows:
• The low level sensor will generate a low level alarm.
• The high level sensor will generate a high level devi-
ation and abort any automatic refill operation.
• When the middle sensor is not satisfied, automatic
refill will begin and will run until either the middle
sensor is satisfied, the high level sensor generates
a deviation (if the middle sensor fails), or the refill
time-out expires.
• The low level alarm and the high level deviation will
clear when the condition clears.
• A button is provided to the user on the Run screens
to initiate an automatic refill operation at any time.
This button can also be used to abort a refill opera-
tion.
Refill Timeout
The refill time-out setting may be set by the user as a
means to abort the refill in the case of a high level sen-
sor failure. When an automatic refill begins, the
time-out counter will begin to count down. If the timer
expires before the high level sensor is triggered, the
refill will abort. A refill must be manually started to
enable auto refills again.
Refill Sensor Type
The Low-Temp Sensor setting limits tank temperatures
to 150°F (66°C). And the High-Temp Sensor setting lim-
its tank temperatures to 190°F (88°C).
NOTICE
If you are using low temperature sensors and select
the High-Temp Sensor setting and set the tem-
perature above 150°F (66°C), damage to the level
sensors will occur.

Conditioning Screen 2
This screen shows the fluid path for the temperature
