I recently added a Navien NCB combi-boiler beside my existing NPE-A water heater. Prior to this I had the dip switches on the NPE set to the intelligent preheating mode and the re circulation system worked wonderfully. Since linking to the NCB, i had to set the NCB as the master and the NPE as the slave, the re circulation has stopped and I can not figure out what settings or dip switch changes I need to make to get this feature working again.
Can anyone help me with this?
