INSTALLATION STEPS
16
Do not disable the low-pressure or high-pressure switches.
The indoor air handler unit filter should be installed and clean.
The indoor air handler unit adjustments should be set correctly.
See
(
Fig. 4 and Table 10 through 12, Appendix A).
Check that all the supply and return registers are clear, not blocked, and open.
Ensure all the covers are in place on the indoor air handler.
Step 8 – Start-up and Programming the Acadia outdoor unit Controller
(NOTE)
In the event outdoor temperatures will not allow the full amount of charge into the liquid line service port, complete the
charge through the ¼” charging port after the system is running.
(NOTE)
The Acadia outdoor unit compressors are equipped with crank case heaters which operate when low oil sump tempera-
tures occur, ensuring separation of the oil and refrigerant. Ensure the crank case heaters are energized before admitting the
initial charge. If power has been lost or the unit has been de-energized for 4 hours or more after charge has been admitted, allow
the crank case heaters to be energized for a minimum of 12 hours before allowing compressor operation. Not following these
warnings may result in compressor chattering and permanent damage to the compressors.
1.
Close the electrical disconnects to energize the system and ensure the system control and thermostat energize.
2.
The thermostat must be setup at this time to properly work with your Acadia outdoor unit; see
(
Table 13, Appendix A).
3.
The outdoor unit must be programmed at this time. The controller has no program set from the factory and will flash P0 at start
up. To set the program, push the Fault History button until the desired program is showing. To lock the program, press the
Reset button for one second; the display will stop flashing and lock in the program. P0 is for an installation using electric back
up heat. P1 is for dual fuel using a furnace for back up heat.
4.
The program can be changed at any time by pressing the Fault History and Manual/Time-Temp buttons simultaneously until the
display blinks. Pressing the Fault History button, you can change the display to the desired program. To lock in the program,
press the Reset button until the display stops blinking. The program will revert back to prior program if no buttons are pressed
for 5 seconds.
The Economy software jumper comes factory set for Economy Mode (J1). When in temperature Bin D and a Y2 input from the
thermostat is active, either H3 w/Y2OUT or H2 will be run based on the mode selected. See
(Table 3 and 4, in Heat Mode, in
Operation Modes).
When set as J0 and in Bin D with Y2 input active, then H3 with Y2OUT on. “Comfort Mode”
When set as J1 and in Bin D with Y2 input active, then H2 with Y2OUT off. “Economy Mode”
The technician change the state of J(x) by:
o
In any mode except Manual, Field Test, Customer Factory Test, or IC Test Eng, press and hold the Reset and
Manual/Time-Temp defrost buttons together.
o
For 2 seconds the current status of the J(x) will be displayed. If buttons are released, the status does not change.
o
If held, the J(x) status will flash for 3 seconds indicating the jumper will change soon. Releasing the buttons while
flashing will abort changing the J(x) status.
o
If held, the J(x) status will change and stay on solid for 2 seconds. After 2 seconds the display will go blank until the
buttons are released.
o
When in Dual-Fuel (P1) mode, the software jumper is not used.
At power up, when in P1 mode, the display will not display the J0/J1 option.
5.
Set the thermostat to Fan ON, ensuring the air flow jumpers are properly placed on the correct pins in the indoor air handler.
