Description<br />
WARM-UP - During warm-up you may also want to display<br />
the actual 1st stage temperature <strong>and</strong> the temperature it is attempting to<br />
reach. The reduced temperature of 285K represents a failure of the<br />
pump to reach 310K in 60 minutes.<br />
Example: WARM-UP 272K/285K<br />
The 285 is fixed <strong>and</strong> the 272 is the response from the<br />
comm<strong>and</strong> K.<br />

WARM-UP - During warm-up you may also want to display<br />
the actual 1st stage temperature <strong>and</strong> the temperature it is attempting to<br />
reach.<br />
Example: WARM-UP 234K/310K<br />
The 310K is fixed <strong>and</strong> the 234 is the response from the<br />
comm<strong>and</strong> K.<br />

EXTENDED PURGE<br />
An H response means that the pump has reached its warm-up temperature<br />
<strong>and</strong> the purge is being extended for some amount of time. The<br />
time is determined when the regeneration parameters are<br />
programmed. The time remaining in minutes is comm<strong>and</strong> k.<br />
