European distributor company)
298
3G router board
NOTE 1: require option 149
NOTE 2: when more than one machine is
installed on site, only one of them shall be
equipped with option 298 while all of them must
be equipped with option 149
NOTE 3: If the Carrier
®
PlantCTRL™ is on site,
option 298 shall be integrated in the Carrier
®
PlantCTRL™ while option 149 is still mandatory
for each single unit.

Variable Water Flow control
299
Hydronic control function package that permits
control of the water flow rate based on different
possible logics (at customer choice): constant
∆T, constant outlet pressure and "fixed-speed"
control. For more details, refer to the dedicated
chapter
When variable-speed pumps on the primary circuit, the
VWF control modulates flow rate through the evaporator,
minimising pump consumption while ensuring safe/optimised
chiller operation
