GENERATION-1 to GENERATION-3 Upgrade

The Next Generation

GENERATION 1

(MIT1)

GENERATION 3

(MIT3)

MIT GEN-1 with FlexCool Controller(Cooling Zones Only)

Air Valve GEN-3 with 3rd Party Controller(Cooling Zones Only)

MIT GEN-3 with 3rd Party Controller(Fan-Powered Heating & Cooling Zones)

Example GEN-1 Zone Upgrade

This wiring schematic is an example of the required modification work.

Job specific conditions, existing controls configuration, and upgrade

scope may require a slight change to the wiring and controls.

Benefits of GEN-1 to GEN-3 Upgrade

1) Improved Flexibility of Controls

a) Open protocol

b) 0-10 VDC

c) 3rd party controls

2) Improved Ventilation Efficiency and indoor air quality

a) Better air throw

b) Better stratification

c) Higher ventilation effectiveness

d) Allows for lower outdoor air

3) Better Controls

a) Improved occupant comfort

b) Increased productivity

c) Reduced energy use

Benefits of GEN-1 to GEN-3 Upgrade

Air Distribution Configuration

Floor supply of cool air and ceiling return provided

that the 150 fpm (0.8 m/s) supply jet reaches

vertical throw is greater than 50 fpm (0.25 m/s) at a

height of 4.5 ft. (1.4 m) or more above the floor.

Note: Most underfloor air distribution systems

comply with this provision.

Floor supply of cool air and ceiling return, provided

low- velocity displacement ventilation achieves

unidirectional flow and thermal stratification or

underfloor air distribution systems where the

vertical throw is less than or equal to 50 fpm (0.25

m/s) at a height of 4.5 ft. (1.4 m) above the floor.

ZONE AIR DISTRIBUTION EFFECTIVENESS

Benefits of GEN-1 to GEN-3 Upgrade

Higher zone air distribution effectiveness

allows for less required minimum amount

of outside air for a space.

Lower amount of conditioned outdoor air.

Lower energy usage.
