1- 3. Configuring HVAC
To begin configuring HVAC, select Configuration from the Main Menu, then
HVAC. If there are no units configured, the screen looks as at left below. If one or
more units are already configured, a “menu” screen will appear that lists all the units,
as at right below. In the example, one unit of each possible type has been added. In
practice, this would be a very unlikely store.
To add a new unit, simply put the cursor on the No. of HVAC Units field and
increase the number by one. A new unit will appear with a default name, which will at
least temporarily be “Unit n”, where n is the new total number of units up to that line.
There are instructions below on how to change the name.
The fields in the HVAC Configuration Menu Evaporator Menu (shown above on the
right) are as follows:
No. of HVAC Units (0 to 45) The number of controlled HVAC units of all
types in the store.
No. of phase loss monitors: (0 to 45) The number of phase loss monitors available
for use by HVAC control. A phase loss monitor can be
used more than once.
No. of humidity sensors: (0 to 5, except that the combined number of humidity
and dewpoint sensors cannot exceed 5). The number
of humidity sensors used for control.
No. of dewpoint sensors: (0 to 5, except that the combined number of humidity
and dewpoint sensors cannot exceed 5). The number
of dewpoint sensors used for control.
Name (Label field, any 15 characters) The name of the
HVAC unit. The field can be edited character by
character (put the cursor on the field, press +/- to
change to edit mode; then use the left and right arrow
keys to move from space to space and the up and
down arrow keys to select the character for that
space. When the name appears as you want it, press
