6.4.1.2.1 Numeric Keypad
The first entry method provides 10 digits for numeric entry, plus the decimal point and a sign key (figure
6.4.1.2.1). The sign key [+/-] will toggle between positive and negative values. Each stroke on the key pad
will echo in the blue input value window above the pad. A change between plus and minus values [+/-]
can be entered at any time during the string entry. Pressing the Enter [
] button will accept the value
and it will become the setpoint.
If the input window holds an illegal value when the Enter button is pressed the system will respond with
an error tone and the entry will turn red. When that happens determine the cause of rejection, delete the
entry using the Delete [
] button and then enter a valid number. The setpoint can only be entered
within the minimum and maximum control range set in the Control Settings App (section 6.4.3.5). These
limits are shown above the numeric entry keypad.

6.4.1.2.2 Step Increments
The second entry method allows the user to enter the setpoint in the same way as the Numeric Keypad
by keying in the value and then pressing the Enter [
] button. The user can then enter the desired
value of step increment and press the Step Up [
] or Step Down [
] button, without pressing the
Enter button. This number will then be used to decrease or increase the existing setpoint value. Subse-
quent touches of the Step Up or Step Down button will continue to increase or decrease the setpoint by
the step value. If the Enter button is pressed the newly entered value will register as a new setpoint value
on the Home Screen rather than a step value.
