Rinnai E75CN Combo Boiler

This unit is about five years old, and for some reason, even though it's 7 degrees outside and in the low 50's inside (with the thermostats set to 68), the baseboard lines are cold, and the display says: 6 Burner off when room thermostat is demanding. When I reset the unit it comes back to the same thing. Any thoughts? Thx
