3.3 UNITS

MANAGEMENT

The menu allows the user to carry out certain operations upon the units controlled by the DDC.
Each machine has a screen associated with it in the

“Units management”

menu, which contains 5 icons that

allow the unit to be managed.

Flame control unit reset:

this option allows the flame control unit of the selected machine to be

reset in the event of arrest.

Error reset:

this option allows anomalies present in the selected unit to be reset (except in the

case of arrest of the flame control unit).

Machine exclusion:

this option allows the selected machine to be excluded from the plant.

Modify set of parameters:

this option allows the parameters set on the machine’s electronic

board to be modified. For a list of the parameters, consult the installation manual of the unit.

Default set of parameters:

this option allows the default parameters memorised in the machine’s

electronic board to be reset.

Manual defrosting:

The option allows the defrosting cycle to be carried out for the selected unit

(GAHP-a and GAHP-AR only).

3.3.1 FLAME CONTROL UNIT RESET

To carry out a reset of the flame control unit if the burner ceases to function, follow the instructions below:

1 - Select from the initial screen to gain access to the main menu.

2 - From the main menu, select

3 - Select the plant (

if the DDC is configured to manage only one hot/cold plant).

4 - Select the machine, using

or . The unit’s identification number is shown between the arrows.

5 - Position the cursor on

and press the knob to carry out a reset of the flame control unit.

6 - Wait for the operation to be performed. If the operation is successful, the message “OK” appears on the

display.

7 - To exit, select

It is not possible to reset the flame control unit on third party machines.
