STPi Controller Operation Manual

Note these additional instructions when connecting a Pump Start Relay:

Master Valve or Pump Start Relay

Step 3

To avoid possible pump damage

when using a Pump Start Relay,

connect a short jumper wire from

any unused zone terminal(s) to

the nearest zone terminal screw

in use.

For example: if you have a 4

Zone Controller with only two

zones in use, route the terminals

for Zones 3 and 4 to the nearest

active terminal (in this example,

Zone 2).

NOTE: Make sure that

the total draw of the

Master Valve or Pump

Start Relay, plus the

draw of the valves does

not exceed 0.650 Amps

at 24VAC, 60 Hz.

NOTE: This Controller

does not provide main

power for a pump.
