1. Ducted Indoor Unit Economizer Summary
The Daikin economizer option allows the FXMQ_PBVJU indoor units to utilize outside air to reduce the mechanical cooling when
the condition of the outside air permits. Automatic, sensor-controlled dampers provide a constant, programmable leaving air
temperature from the economizer whenever the indoor unit receives a call for cooling and the outside air conditions satisfy
enthalpy requirements. This allows the indoor unit expansion valve, and in turn the compressor, to operate at part load
conditions to maximize energy efficiency.

3. Shipping and Packing List
Economizer package contains:
1 ea. –Economizer Assembly
1 ea. –Install Instructions Including Wiring Diagram
3 ea. –Wire Ties
1 ea. –Honeywell JADE Operation Manual
4. Installation
Before starting the installation work, carefully read the following safety precautions.
a) Disconnect all power to the indoor unit
b) Remove the factory duct flange from the return inlet of the indoor unit.
c) Attach the economizer over the return opening with sheet metal screws.
d) Remove the control access panel on the economizer and indoor unit.
e) Route wires from the indoor unit control box to the terminal strip located in the economizer control panel. Route a
field-supplied 24VAC power supply to the economizer terminal strip and the KRP1C74. Refer to wiring diagram, Figure 3.
f) Replace the control access panels on the economizer and indoor unit.
g) Place the return air duct and fresh air duct over the economizer return and fresh air dampers.
Note: Economizer section may be rotated 180° for bottom fresh air connection.
5. Operation Mode
A. Cooling Mode
1. While in cooling thermo-on, with the ambient temperature and humidity above the enthalpy control set point, the
fresh air damper will open to the minimum vent position and the cooling demand is satisfied by the compressor.
The minimum vent position is site-configurable.
2. While in cooling thermo-on, with the ambient temperature and humidity below the enthalpy control set point, the
fresh air damper will modulate to ensure the mixed air supplied to the indoor unit is no lower than the set point
temperature. This will reduce the mechanical cooling of the indoor unit and VRV System . The mixed air set point
should be configured in accordance with the operating conditions of the fan coil.
Figure 1. JADE Economizer Module
B. Heating Mode
1. While in heating thermo-on, the damper will open to the minimum position. The minimum position is
site-configurable.

C. Fan Mode
1. While in fan only operation, cooling thermo-off, and heating thermo-off, the damper will open to the minimum vent
position. The minimum vent position is site-configurable.
D. Enthalpy Control
1. The enthalpy economizer control senses both temperature and humidity of the outside air. When the heat content
of the outside air is below the control set point, the control permits the outside air dampers to operate as described
in section 5.A.2. above. When the heat content rises above the control set point, the control closes the outdoor air
dampers to the minimum vent position. This setpoint can be adjusted as needed.
Figure 2. Single Enthalpy Curve and Boundaries
Table 3. Single Enthalpy and Dual Enthalpy High Limit Curves
E. Settings
1. The mixed air temperature set point must be no lower than 65 °FDB for continuous operation. This may be
configured down to 60 °FDB, however thermo off may be carried out due to freeze protection.
2. The economizer is recommended for standard comfort cooling applications only. This must not be used for high heat
density, year round cooling applications.
3. The enthalpy curve setting must not be programmed to ES4 or ES5.
6. Wiring Diagram
Provide field supplied 24VAC power supply and 18 gauge, stranded wire as indicated in Figure 3. All wiring and electrical work
should conform to applicable national, state, and local codes.
