I changed my supply temperature from 180 F to 140 F and the baseboard sizing appears to be failing.
** Severe ** SizeBaseboard: Autosizing of HW baseboard UA failed for ZoneHVAC:Baseboard:Convective:Water="1ST:RETAILBLOCK WATER CONVECTOR"
** ~~~ ** Bad starting values for UA
** Fatal ** SizeBaseboard: Preceding sizing errors cause program termination
Could someone suggest what could be causing this.
thanks.
