Jandy Pure Link goes into Spillover mode when Boost turned o

Installed a Jandy Purelink system in the begining of the summer and works perfectly except for one thing. When I turn on "Boost" mode the system goes into "Spillover" mode and a mesage on the remote says "Sstem will remain in spillover mode while in Bosst mode" and I cannot turn off spillover. I called Jandy and they indicated the mode should not change when boost is activated. It has done it since the installation so I must have done something wrong. If I turn the number 3 dip switch off "No Spillover" everything works OK, but then I can't use the spillover.

You don't want to run a SWG on boost when chlorinated water is going into the spa without the spillover running. If you do the chlroine level in the spa could get way too high. Presumably the Purelink system is trying to protect you from that.
