5.2 Programming
5.2.1 General
Most of the settings are entered using the numerical keypad. If a mistake is made it can be corrected by
pressing the ‘DEL’ key and retyping the number before pressing the ‘ENTER’ key to enter the new setting value.
Nearly all of the settings are two digit numbers. When entering a value less than 10 the first digit MUST be en-
tered as a zero, an invalid setting will not be accepted by the control.
