There are three settings available to the user:<br />
• 0 - Power Fail OFF<br />
• 1 - Power Fail ON<br />
• 2 - Power Fail Cool<br />
NOTE: If Power Fail Cool is selected, <strong>and</strong> the power failure occurs while<br />
the waterpump is ON, the waterpump will only cool down if it is below the<br />
power fail recovery temperature setpoint. If the waterpump temperature is<br />
above the setpoint, the waterpump will remain OFF.<br />

Power Fail Recovery Temperature<br />
The twelfth parameter of the REGEN function allows the user to establish<br />
a temperature setpoint which the <strong>On</strong>-Board Waterpump uses to decide<br />
whether to cool down, or to perform a REGEN cycle after a power failure<br />
has occurred <strong>and</strong> power is restored. Refer to Figure 3-21.<br />
