installed according to the thermal zoning of the building,
and each fan coil is fitted with a Pressure Independent
Control Valves (PICV) & EC Fan motors that varies

temperature to ensure a maximum level of comfort.
Heating is achieved by the reverse cycle heat pump
capability of the chillers, with the hot water being
reticulated through a dedicated closed loop piping
system to the in-ceiling fan coil units. This system
decreases electrical demand of the building by a third
when compared to electrical resistance heating.
During times when the building is running under
generator power only, the system can be configured to
run only using the thermal storage in the tank to provide
limited cooling. This reduces the size of the building
