Connect Valves

Route all eld wires through the opening at the bottom

A

of the unit, or through the knock-out in back of the unit.
Attach conduit if desired, as shown.

Connect one wire from each valve to one of the numbered

B

station terminals (1-12) on the controller, as shown.

Connect a eld common wire (C) to the common terminal

C

(C) on the controller. Then connect the remaining wire
from each valve to the eld common wire, as shown.

Connect Pump Start Relay (optional)

The ESP-TM2 can control a pump start relay, to turn the
pump on and off as needed.

Connect a wire from the pump start relay (PSR) to the

A

master valve terminal (M) on the controller. Then connect
another wire from the pump start relay to the eld
common wire, as shown.

To avoid the possibility of damage to the pump, connect

B

a short jumper wire from any unused terminal(s) to the
nearest terminal in use, as shown.

NOTE: The ESP-TM2 controller supports one valve



solenoid per station terminal.
