OPTIONAL OUTDOOR AIR (Shall be made available by
either/or):
•
ELECTRONIC ENTHALPY AUTOMATIC ECONO-
MIZER - Outdoor and return air dampers that are inter-
locked and positioned by a fully-modulating, spring-
return damper actuator. The maximum leakage rate for
the outdoor air intake dampers shall not exceed 2%
when dampers are fully closed and operating against a
pressure differential of 0.5 IWG. A unit-mounted potenti-
ometer shall be provided to adjust the outdoor and return
air damper assembly to take in CFM of outdoor air to
meet the minimum ventilation requirement of the condi-
tioned space during normal operation. During econo-
mizer operation, a mixed-air temperature control shall
modulate the outdoor and return air damper assembly to
prevent the supply air temperature from dropping below
55°F. Changeover from compressor to economizer oper-
ation shall be provided by an integral electronic enthalpy
control that feeds input into the basic module. The out-
door intake opening shall be covered with a rain hood
that matches the exterior of the unit. Water eliminator/fil-
ters shall be provided. Simultaneous economizer/com-
pressor operation is also possible. Dampers shall fully
close on power loss.
•
MOTORIZED OUTDOOR AIR DAMPERS - Outdoor and
return air dampers that are interlocked and positioned by
a 2-position, spring-return damper actuator. The maxi-
mum leakage rate for the outdoor air intake dampers
shall not exceed 2% when dampers are fully closed and
operating against a pressure differential of 0.5 IWG. A
unit-mounted potentiometer shall be provided to adjust
the outdoor and return air damper assembly to take in
the design CFM of outdoor air to meet the ventilation
requirements of the conditioned space during normal
operation. Whenever the indoor fan motor is energized,
the dampers open up to one of two pre-selected posi-
tions - regardless of the outdoor air enthalpy. Dampers
return to the fully closed position when the indoor fan
motor is de-energized. Dampers shall fully close on
power loss.
