JUMPERS:
The programming jumpers are as follows (0=off,
1=on):
JP Bit
1 0 off = externally heated on = blower dryer
2 1 on = energy management sensor installed
3 2 on = dew point sensor installed
4 3 on = no cooling (blower purge only)
5 4 on = tower pressure switches installed
6 5 on = not used (fast cycle for development,
V3.5 and prior)
7 6 on = to download language text (factory
use)
8 7 on = to enable factory set-up screens
Determining jumper positions:
Each jumper 8 bits weighted by position

Example:
If jumper 8, 5, and 1 are installed, a value of 128+16+1
= 145 is returned
To decode, the algorithm:
· If (number >= 128)
jumper 8 = on
· number = number - 128
· If (number >= 64)
jumper 7 = on
· number = number - 64;
· etc.....
