5.2.c Configuration Page
The Configuration page is used to change the method for communicating
to the heater and to select optimal PID settings for high flow or low flow
operating conditions.
Button F1 enables local operation (
) through the graphical user
interface or remote operation (
) through an external hardware
interface. When remote operation (
) is selected, the temperature
set point cannot be adjusted nor can the heating of water be enabled
or disabled locally through the display panel as described in section
5.2.a.
Button F2 enables the optimal preset PID configuration for High flow
(
) or Low flow (
) conditions. Refer to Table 5-1 when deciding
to select the Low flow (
) or High flow (
) configuration during
critical process steps.
