Standby Mode:

The display defaults to this mode at startup or reset of the control. If no key is pressed for 20 minutes the display will return to this mode. The function of the keys may be two-fold as shown below.

The MACH boiler is equipped with a combination combustion and temperature control. This control monitors combustion and lighting of the boiler, as well as maintaining temperature of the supply water. The temperature control portion modulates the boiler to maintain the desired outlet temperature based on the selected operating configuration.

CAUTION!

The user should become thoroughly familiar with the operation of the boiler and controls before

3.12.1.1 Operation of the Control

The boiler is operated through the control/display panel. The display has 3 modes of standard operating menus. The modes are:

Standby mode will display (Stby)

Parameter mode will display (PArA)

Information mode will display (InFo)

At each level the keys and the display have different functions. To ascertain which mode you are in, the displayed information will be shown as indicated under “display”.

*Note: Long duration is greater than 2 seconds.

When in the Standby Mode the control indicates boiler status with the first digit of the display. The remaining digits indicate the boiler's actual temperature or lockout code. The following table indicates the meaning of the display digits when in the standby level.
