7. How to Read Location Values
Values within a data program location will be displayed by the zone LEDs in binary coded decimal format
i.e. zone LEDs 1-4 indicate units (ones) and zone LEDs 5-8 indicate tens (tens), and so on.
To read a binary value on the keypad, add up the values represented by each lit LED as shown in Table
1.

EXAMPLE:
Imagine the following zone LEDs are on: Zone 1, Zone 3 and Zone 5.
Units are represented by the sum of Zone 1 and Zone 3 (i.e. 1 + 4).
Tens of units are represented by the value of Zone 5 (i.e. 1 x ten).
Therefore, the displayed value is (1+4) + (10) = 15.
Values within a time program location are displayed in a similar format as per Table 2.

Using an LCD keypad means that data and time information can be read directly without a need to
convert.
