What’s Changing:
New DX DOAS Controls option for Split Systems. A DX DOAS Controls option has been added for Split Systems, allowing selection of CF with H3 or V3 matched pairs, with ISMRE2-70 and ISCOP values rated in accordance with AHRI 920.
H3 C/D energy recovery sections updated to work with 3-phase heat wheel motors, slightly increasing the length of the energy recovery cabinet.
H3/V3/SB exhaust fan options have changed. The 450AQ fans have been turned off, and the 310AX has been turned on for single phase voltage.
General Updates:
Updates to factory provided controls will cause minor price changes on the following units: RN B-C cabinet when A1=K and F16B=N, RNA-016 when A1=H and F16B=N, RQ when F4A is not ‘Q’ and F16B=N, and the SB.
For all units, fixed an issue where validation failures were not being reported to the user after moving to the 'Unit Performance' tab.
Note that this may cause certain units to be unable to save when they could previously. The error message should give an explanation of specifically what is preventing saving.
Added the ability to select multiple units/accessories when retrieving drawings.
Fixed an issue causing performance to vary after reaching the Unit Performance tab and returning to the Fan Selection tab.
This issue affects water-source heat pump units and other units with energy recovery or electric preheat where the mixed air temperatures must always be calculated.
Split line sizing for H3/V3 units paired with CF units has been updated to account for heating mode on systems configured as heat pumps.
This includes overall updates to the performance engine so results for existing line sizing may change slightly. It is recommended that line sizing be redone for any split heat pump
