6. PARAMETER TABLE and factory default settings
IMPORTANT : Always set parameter “tC” first. As you move “tC” between settings 1 to 5, all non- relevant parameters
will become masked out. Once “tC” has been set correctly, you can then alter any other parameter if you need to.
WARNING!!
Always switch the power OFF then ON at the end of programming to initiate changes.
If parameter “tC” is set to 4 or 5 without an evaporator probe fitted, a P2 probe alarm will be generated. If you
do intend to use settings 4 or 5 fit a probe, if you intend to use settings 1, 2 or 3, you must switch the power
OFF then ON again to clear the alarm.
