LOL - I've not been on this forum for years, and today received notification of your post... How you doing ?
Like I said I've not been active on here for some years, and no longer program in PBP so I'm rusty when it comes to the workings 
Comments taken form that library file file suggest
Code:
'-- To REMOVE SENSORS perform the following: --
'-- 1. Change the "AM2302_MAX_SENSORS" constant to the correct number. --
'-- 2. Comment out the appropriate "AM2302_Sensor_x" Alias lines. --
'-- 3. In the "AM2302_Read" subroutine in the library file, --
'-- edit the "select case AM2302_Sensor_Num" block, comment out the --
'-- "Case x" portion for the sensor number you want to remove. --
'-- 4. Comment out the entire "AM_Readx" subroutine at the end --
'-- of this library file for the sensor you want to remove. --
and this needs editing
Code:
'****************************************************************************
'*** EDIT THIS SELECT CASE BLOCK TO ADD/REMOVE SENSORS (see instructions) ***
'****************************************************************************
select case AM2302_Sensor_Num
case 1 'Sensor #1
gosub Read_AM1
case 2 'Sensor #2
gosub Read_AM2
case 3 'Sensor #2
gosub Read_AM3
case 4 'Sensor #2
gosub Read_AM4
end select
Looking at the code for the version of thermostat that I used as a test platform when Tabsoft was developing the library the main program has this line in the set up area of the code (using include "AM2302_LIB_v024.bas" )
Code:
;----[AM2302 ]------------------------------------------------------------------
AM2302_MAX_SENSORS con 4 ' Number of Sensors Used
I then used a word array for the temp and humidity values
Code:
AM2302_H var word[4] ' AM2302 sensors - Humidity values
AM2302H1 var AM2302_H[0]
AM2302H2 var AM2302_H[1]
AM2302H3 var AM2302_H[2]
AM2302H4 var AM2302_H[3]
AM2302_T Var Word[4] ' AM2302 sensors - temperatures
AM2303T1 Var AM2302_T[0]
AM2303T2 Var AM2302_T[1]
AM2303T3 Var AM2302_T[2]
AM2303T4 Var AM2302_T[3]
I guess if using just the one sensor this could be a straight word variable
I then have a link to a subroutine
Code:
for cn=1 to 4
Pid_channel=cn-1
AM2302_Sensor_Num = cn
gosub read_dht
And the subroutine it links to is
Code:
read_dht:
gosub AM2302_Read
AM2302_H[Pid_channel]= AM2302_Hum
AM2302_T[Pid_channel]= AM2302_Temp
if AM2302_Temp/10=0 then return
serout2 portB.0, 84, [$1B,"[H"]
serout2 portB.0, 84,[$1b, "[", dec cn+1, "B"]
serout2 portB.0, 84, [$1B,"[11C"]
serout2 portB.0, 84, [dec AM2302_Temp/10,".",dec AM2302_Temp//10]
serout2 portB.0, 84, [$1B,"[H"]
serout2 portB.0, 84,[$1b, "[", dec cn+1, "B"]
serout2 portB.0, 84, [$1B,"[17C"]
serout2 portB.0, 84, [dec AM2302_Hum/10,"%"]
Return
Ignore all the serial out commands, I was using a serial to GLCD adapter at the time. The gosub called in the above subroutine is in the library file.
Hopefully that dissection of my old program helps ? I sold my old EasyPic5 board at the beginning of September this year, and uninstalled PBP years ago, so have no means to test, but the code ran for a few years in the controller before I move to the dark side and ported the code to an Arduino Mega to take advantage of colour TFT screens.
