I have a newly installed Solo 60 that is propane fired and have been slowly tweaking the system. My ODR reading on the display is off about 8 degrees, for instance the display will state 44 and the actual outdoor temp of the sensor housing and shingles around it are 36 degrees. Is this something that can be adjusted and or should this be a warranty item? My second question is when a thermostat calls the circulators turn on and the zone valves take around a couple of minutes before they open. Is it ok for the circulator to attempt to pump against a closed zone valve? Thanks
