We have a Navien heat/hw system. Have hot water but no heat. Called Navien but they could not help. Told us to call plumber. Left message for plumber but it is a cold Friday night. No error codes. Any ideas??

    Thank you for the responses. After troubleshooting and coming away completely perplexed we noticed that the thermostat had a flashing battery on it.....yes needed new batteries. Have to remember to check the simplest things first. We have heat!! Thanks again.
