5.0 SYSTEM START-UP AND REFRIGERANT CHARGING
5.5 Entering Charge Mode Using
EcoNet
™
Control Center Service
Menu
1. Set the "Mode" to the "OFF" position.
2. Select "SERVICE" on the EcoNet™ Control Center
screen.
3. Select "ODU Checkout". If the next screen displays
a flashing "Lock-Out" message, there will be up to
a 5 minute delay before it is possible to continue.
4. Once the flashing lock-out message disappears,
touch OFF on the screen displayed to the right of
"Var Speed ODU Test".
5. Touch the "UP" arrow repeatedly until the "Heat
Charge" or "Cool Charge" menu item is displayed
depending on which mode the system is to be
charged in.
6. Touch "Start Test".
7. System will now operate at 100% of capacity
and indoor air-flow to allow proper indoor air-flow
verification and refrigerant charging until the Charge
Mode is manually ended. There may be a delay
before the system actually starts. If the system
doesn't start, cycle power to both the indoor and
outdoor units and repeat steps 1-6.
8. Note: When charging in the heating mode, the sys-
tem will initiate a defrost cycle every 34 minutes if
the coil temperature is below 35ºF [1.7ºC] to assure
the coil stays frost free during the charging process.
Allow the system to complete the defrost cycle and
stabilize for at least 10 minutes before attempting to
evaluate the charge level.
9. To end Charge Mode, touch the "UP" arrow repeat-
edly until "OFF" is displayed on the screen and then
touch "Stop Test". Then touch the left arrow on the
screen to return to the main screen.
10. If the indoor blower continues to run continuously
after exiting the Charge Mode, cycle the power to
the air-handler or furnace.
5.6 Entering Charge Mode
When Using a Universal
Outdoor Control
1. Set the thermostat to the cool or heat mode
depending on which mode the system is to be
charged in.
2. Adjust the set point several degrees below
(cool mode) or above (heat mode) the room
temperature to assure the thermostat is calling
for operation and will continue to do so throughout
the charging process.
3. When the charging process is complete, adjust
the temperature set-point to the desired level.
NOTE: If installing an RD17 unit using a traditional
24V thermostat, complete the charging procedure
before installing the jumper on the U1 and U2
terminals, if applicable. While charging, ensure that
there is a 24V signal to both the Y1 and Y2
terminals on the UODC board in the outdoor unit,
and that the indoor air mover is on high stage.
