For best c
onnections all gr

unit malfunction.
Added loads on any pow

voided.
Direc

Typical curr
ent draw f
or a 2”-3” valv
e is 2-4 amps in a 12 v

INITIAL SETUP
The Contr
oller must be calibrat
ed when used f
or the first time with a ne
w valv
e or with a differ
ent valv
e. When us
ed for the first
time, the LED Bar Graph Displa
y will flash indicating calibr
ation is needed.
Calibration can be done e
asily by ac
ces
sing the Setup Mode shown belo
w.
Note: When a C
ontroller is us
ed as an Auxiliary, the Setup Mode is not ac
ces
sible. Calibration and s
etup are only
neces
sary f
or a Master C
ontroller
.
SETUP MODE
Pres
