Description
This bit is set to “1” when fan is running at alarm speed. Once read, this bit is not
reasserted on next monitoring cycle, even if the fan is still running at alarm speed.
This bit is set to “1” if Fan 1 becomes stuck or is running under speed.
“1” indicates Remote 1 high temperature limit has been exceeded. If the temperature
is still outside the Remote 1 Temp High Limit, this bit reasserts on next monitoring
cycle.
“1” indicates Remote 1 low temperature limit exceeded (below). If the temperature is
still outside the Remote 1 Temp Low Limit, this bit reasserts on next monitoring cycle.
“1” indicates Remote 1 temperature THERM limit has been exceeded. This bit is
cleared on a read of Status Register 1.
This bit is set to “1” if a short or open is detected on the Remote 1 temperature
channel. This test is only done on powerup, and if set to 1 cannot be cleared by
reading the Status Register 1.
This bit is set to “1” if a short or open is detected on the Remote 1 temperature
channel. This test is only done on powerup, and if set to 1 cannot be cleared by
reading the Status Register 1.
“1” indicates Local Temp Low Limit has been exceeded (below). If the temperature is
still outside the Local Temp Low Limit, this bit reasserts on next monitoring cycle.

Description
This bit is set to “1” when Fan 2 is running at alarm speed. Once read, this bit is not
reasserted on next monitoring cycle, even if the fan is still running at alarm speed.
This bit is set to “1” if Fan 2 becomes stuck or is running under speed.
“1” indicates Remote 2 high temperature limit has been exceeded. If the temperature
is still outside the Remote 2 Temp High Limit, this bit reasserts on the next monitoring
cycle.
“1” indicates Remote 2 low temperature limit exceeded (below). If the temperature is
still outside the Remote 2 Temp Low Limit, this bit reasserts on the next monitoring
cycle.
“1” indicates Remote 2 temperature THERM limit has been exceeded. This bit is
cleared on reading Status Register 2.
This bit is set to “1” if a short or open is detected on the Remote 2 temperature
channel. This test is only done on powerup, and if set to 1 cannot be cleared by
reading Status Register 2.
“1” indicates local temperature THERM limit has been exceeded. This bit clears on a
read of Status Register 2.
Set to “1” when THERM is pulled low as an input. This bit clears on a read of Status
Register 2.
