| There should be no difference as heat loss from the building doesn't change. However check your supply air temps and outside air settings. If your supply air temp is lower than the mixed system and outside air is delivered as a percentage of supply air, your air volume will be higher, and as a consequence so will your outside air. More outside air more heating. More air volume is more fan power unless you reduce static pressure or raise supply air temp. Sent from Yahoo! Mail for iPad |
