b. SETUP Menu :
The setup menu can only be activated from an idle screen (See
d below). Once the setup menu is active,
the buttons possess the following functions:
- <SPEEDUP>: Scroll to previous menu item.
- <SETUP>: Scroll to next menu item.
- <TRIP VIEW>: Softkey – The text above the key explains the function.
- <TRIP STEP>: Softkey – The text above the key explains the function.
The setup menu will remain visible for 1 minute after the last button has been pressed. After this
time, the system will return to the idle screen and any changes made will be lost unless already
saved. The board provides an opportunity to save at completion of setup choices.
Press and hold the <SETUP> button until the
<Setup Menu> is displayed on the screen then
release it to enable scrolling through the
menu.
As soon as the <SETUP> button is released,
Stage 1 compressor 1 runtime hours is
displayed:
Press <TRIPSTEP> to clear this compressor's
runtime hour count (if needed).
Now press the <SETUP> button again. Stage 1
compressor 2 runtime hour is displayed:
Pressing the <SETUP> button again brings up
Stage 2 compressor 1 runtime, pressing <SETUP>
one more time brings up Stage 2 compressor 2.
Again, press <TRIPSTEP> to clear each
compressor's runtime hour count (if needed).
Now press the <SETUP> button again. The MODBUS
address is displayed:
This allows the MODBUS address to be set.
Press <TRIPVIEW> to increment the address, or
<TRIPSTEP> to decrement. Holding either button
will start automatic counting.
Pressing the <SETUP> button again gives a
choice of “Control source”. Possible
choices are either “thermostat” or
“MODBUS” control. Pressing the <TRIPSTEP>
button toggles between "Thermostat" or
"MODBUS" control. (Choosing Thermostat
control does not remove the ability to
display MODBUS available outputs.)
