navien keeps shutting down error e002 low pressure on heating side , Installer says caused by leaky pressure relief valve that he will come back and replace and bleed system , after holidays. Unfortunatley its not restarting now and its Christmas morning. Can I trick the system into start up somehow thru programming and shuting off the heating side so I can have hotwater until he gets back off holidays. And have a SHOWER!
No announcement yet.
