For this purpose, never use a device that cycles the main power to the
UltimateAir 200DX. Cycling main power ON/OFF is detrimental to the
system electronics and will void the warranty.

When installing the UltimateAir 200DX with existing forced air ductwork, you
may need to operate in conjunction with the furnace/AC air handler. To wire
the UltimateAir 200DX to run with the existing forced-air system, use the
existing furnace wiring diagram in conjunction with the directions below.
1.
On the Furnace Air Handling Device, locate the 24 VAC (low voltage) output
and common connections. Furnace outputs are usually marked G for Go
and C for Common; refer to the furnace manual for details.
2.
On the UltimateAir 200DX, REMOVE jumpers JP6 and JP7, located just
under the temperature sensor input.
3.
Run two wires (20/22GA) from the furnace to the input terminals on the
UltimateAir 200DX main control marked
F1 (24 VAC Line) and F2 (24 VAC
common). The UltimateAir 200DX will now run only when the furnace air
handler is ON.
See the 3Motor Main Controller diagram in this manual.
Note- When wired to run with the furnace blower, the UltimateAir 200DX will
run at the Flow Speed Setting on the 200DX Wall Dial. The green light on the
Wall Dial will flash when the furnace blower is not running.

This control scenario will utilize the UltimateAir 200DX internal 24Vac
transformer power for ON/OFF function.
On the UltimateAir 200DX 3Motor Main Board, REMOVE jumper JP6, located
just under the temperature sensor connection. Run one Wire from the LINE
Terminal to the Dry Contact Device you want to use. Run a second wire back
from the Dry Contact Device to the UltimateAir 200DX
F1 Terminal.
