Station Valve Wiring
Connect each valve by its own separate power wire to one
of the numbered terminals on the ESP-TM flip strip, as
shown in the illustration.
Connect a common wire to one of the leads on each valve.
Connect the other end of the common wire to the COM
terminal on the flip strip. Wire used to connect the valves
must be code-approved for underground installation.
Master Valve Wiring
NOTE:
Complete this section
ONLY
if your system requires
a master valve (an automatic valve installed on the mainline
pipe upstream from the station valves).
Connect the master valve wiring to the MV terminal and
COM terminal as shown in the illustration.

Pump Start Relay Wiring
NOTE:
Complete this section
ONLY
if your system requires
a pump start relay.
The MV terminal on the flip strip can be used to connect a
pump start relay. Connect one lead of the 24VAC pump
start relay to the MV terminal and the other lead to the
common wire, as shown in the illustration.
CAUTION:
To prevent pump damage when using a pump
start relay, use a jumper to connect unused stations to a
station that is being used. If program information is lost
during a prolonged power outage, the ESP-TM will auto-
matically run a "default" program when power is restored.
This program runs all stations for 10 minutes. If unused
stations are not jumpered, the pump will operate with no
flow (dead-head) during this 10-minute period. Dead-
heading may cause the pump to overheat or burn out.
