The remote room sensor supplied with the Zone Reset option will also allow
modification of the Zone Air Set Point. This can only be changed on the remote
room sensor assigned as address 2. Pressing the UP or DOWN buttons will
display and flash the current set point. Pressing the UP or DOWN buttons
again will change the set point in 0.1º increments. Pressing and holding down
these buttons will allow for a faster scroll of the set point. The last displayed
value will become the set point after a few moments. The set point will assume
the value of the last device to modify it, either the remote room sensor or the
display terminal.
