PUMP START RELAY / MASTER VALVE WIRING

RAIN SENSOR INSTALLATION

This section is only for systems that require a pump 
start relay or master valve. The controller does not 
provide main power for a pump. 

Master Valve or Pump Start
Relay wiring terminals
“COM” & “MV/PS” are
located at the lower right 
corner of the cabinet.

NOTE: JUMPERS FOR 
UNUSED STATIONS

To prevent pump or system 
damage when using a pump 
start relay, use a jumper to 
connect all unused stations
to the last station with a 
run time.

Unused station(s) without a 
jumper could cause pump or 
system damage should the 
unused station be turned on.
Pump operation with no flow 
(dead-head), could cause
over-pressurization of the 
system or the pump to 
overheat.

 

All electrical connections and wiring must
be made according to local building codes.

1.   Open the cabinet door.

2.  Open the front panel by grasping  

the finger-hold on the top right side  
of the front panel. Swing the panel 
open to the left.

3.  Connect the two rain sensor wires
  to the two terminals marked SENSOR 
  located in the lower right corner of
  the cabinet.

NOTE: 

If a rain sensor has not been 

installed in the PRO EX 2.0 controller, the 
pre-installed jumper wire must remain 
installed on the SENSOR terminals.

For wireless rain sensors needing 
an additional power source, use the 
VT terminal for 24VAC and use the 
COM terminal for the common. 
Both are located in the lower left
corner of the cabinet.
