Decoder Address Assignment
For easier installation, install field decoders with
address numbers in numerical order, starting with
the master valve first.
B
NOTE: Organize decoders numerically and
mark each decoder box with the decoder
address.
Write Station No. on the Decoder Carton.
Master Valve Address
If there is no master valve then station #1 will be
the lowest address in the decoder sequence.
For example:
• Table 1.1 shows a system with NO master valve.
Decoder address #10001 is automatically paired
to station #1.
• Table 1.2 shows a system WITH a master valve.
Decoder address #10001 is automatically paired
to the Master Valve. Decoder address #10002 is
then automatically paired to station #1.
• See Figure 1 for example of decoder addressing
with master valve.
