You select the desired option by entering the matrix position. Movement through the matrix is accomplished by using
the “V” and “H” buttons to move to another row or column, as shown in the example below. At any location where a
value may be changed by the user, the desired value is programmed using the “+” and “-” buttons.
4.2.1 Example
To set the dew point value to -10°C for 4 mA (V1 H2 on matrix):
1. Press the V key until the display shows V1.
2. Press the H key until the display shows H2.
3. Use the + or - key to change the numeric value to -10. The digit to be changed is flashing.
4. Proceed to any part of the matrix.
4.3 Special Functions of the Push Buttons
1. Reset to “Normal” Display: Pressing the “V” and “H” buttons simultaneously returns the user to VH 00 (normal
display).
2. Display Only: Note that seven (7) matrix locations are for display only and may not be changed by the user (refer
to
Table 1 on page 16 or “Matrix Table for Programming” on page 33 ). The “display only” fields are as follows:
• VH 00 = normal display (in dewpoint)
• VH 08 = indicates digitized moisture signal
• VH 40 = temperature display
• VH 90 = during a system alarm, displays the error code for the fault encountered
• VH 91 = during normal operation, the previous error code is displayed for reference
• VH 92 = displays the factory issued identification number
• VH 93 = displays the factory issued reference number designating the device type and software version
3. Default Values

A default value is assigned to each programmable matrix field. The values are present after a reset to factory
programmed data has been executed (see VH 95).
