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 Numeric Keypad
Setpoint Entry). 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 (
6.4.3 Control Settings
Application
). These limits are shown above the numeric entry keypad.

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 Enter [
] button. The user can then enter the desired value of step increment and press 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. Subsequent 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.
