For some configurations and functionalities, a programmable control is used.
The figure shows the main screen.
From the main screen, the "Prg" button is pressed to access the "Q0" screen of the "Menu" branch.
4.7.6.1 Switching the unit on/off
To switch the unit on or off, from the "Q0" screen of the "Menu" branch, scroll the various selections of the branches
using the arrow buttons until the unit "On/Off" selection appears highlighted.
Confirm with the "enter" button to access the "N0" screen where the operating state of the unit is shown with the
instruction for changing it.
The unit can be switched on from the keypad depending on whether all the other OK signal inputs for starting are
closed/enabled.
The unit can always be switched off from the keypad.
4.7.6.2 Changing from cooling to heating and vice versa
The change of operation can take place in one of the following three ways, according to the programming required
by the customer:
- automatically as the temperature changes in the environment to be controlled;
- manually using the keypad or by remote management;
- by means of the digital input.
When the change is made from the keypad, from the "Q0" screen of the "Menu" branch, scroll the various selections
of the branches using the arrow buttons until the "Sum/Win" selection appears highlighted.
Confirm with the "enter" button to access the "R0" screen where the operating state of the unit is shown with the
instruction for changing it.
4.7.6.3 Displaying and changing the operating set points
From the "Q0" screen of the "menu" branch, scroll the various selections of the branches using the arrow buttons
until "Setpoint" appears highlighted. Inside the "Setpoint" loop, there are screens where the various set points can be
changed within factory-set limits.
Confirm with the "enter" button to access the "S0" screen, where the cooling temperature set point is shown, and to
position the cursor at the top left. The "enter" button is used to access the field for changing the value, which can be
done using the "arrow" buttons. Press the "enter" button again to confirm the set value and return the cursor to the
top left.
When the cursor is at the top left of the screen, the down arrow button is used to go to the "S1" screen where the
heating temperature set point is shown.
The "enter" and "arrow" buttons can also be used in the same way to change and confirm the value of the set point
shown in the screen and move on to the next one.
The other screens that can be accessed if included in the configuration of the unit, are the "S5" and "S7" screens for
the air flow rate set points.
