OPTIONAL FEATURES
EC Plug Fans
Available instead of forward curved belt driven fans. The EC
plug fan is a backward curved fan with integrated EC
electrically commutated motor which is controlled directly
from the microprocessor using a 0-10V output. Options on
setup are :
Unit is set up with a discrete fan speed based on a fixed 0-10V
output to the EC motor based on the design point of operation
of the fan. This is the default setting on units shipped.
Unit set up to track the cooling control temperature band with
set voltage limits whereby max voltage / fan air volume is at
set point plus control band & min voltage / fan air volume at
set point. Max air volume is typically design air volume & min
air volume is around 60% for chilled water units. This is
something that can be proven on site. Minimum value needs
to ensure there are no hot spots due to lack of airflow & that
there is no loss of sensible cooling capacity to latent cooling
capacity at the cooling coil.
Unit set up to give a reduced fan air volume in
dehumidification mode to conserve energy in
dehumidification
while
quickly
achieving
the
dehumidification effect at the cooling coil. This output voltage
is again user selectable.
Unit is set up via an underfloor pressure transducer to give a
fixed underfloor pressure all the time. Underfloor pressure
setpoint is input through the unit user display.
3 Stage Reheat
Available in lieu of 2 stage by adding an electrical contactor
& configuring the software to 3 stage.

thyristor giving a fully proportional 0-10V output of the reheat
capacity.
Hot Water Reheat
Units shall be fitted with a Low Pressure Hot Water (LPHW)
heating coil in place of the standard electrical heating. Water
