LOW FLOW
SETPOINT
This button allows adjustment of the LOW FLOW SETPOINT. This setting
will disable the heaters when the flow rate through the heater falls below this
setting (liters per minute). The controller will provide a warning message
when the flow rate has dropped below this setting, but it will not enter an
alarm state. When the flow rate through the heater has risen above the value
of this setting heater operation will continue. This setting is factory set to the
valued listed below:

105Kw – 144Kw

BOOST GAIN
This button allows adjustment of the BOOST GAIN. This setting improves
heater performance during initial temp rise from a low temperature. This
setting has a range of 0-100 (no units). It is factory set during testing. The
factory set value is saved in the FACTORY DEFAULT menu. By increasing
the value of this setting (by increments of 1), the heater will increase the rate
of temperature rise from a low temperature. Note however that increasing the
value of this setting will result in a temperature overshoot as the heater outlet
temperature reaches the process setpoint. The default value will provide the
quickest rate of temperature rise with no temperature overshoot above the
process setpoint.
