Install Instructions
just high enough to clear the locking posts, rotate the actuator
180° and reinstall it on the locking post by following the previous
instructions for reassembling the actuator.
4. The plug-in quick connects can be disconnected from the valve
actuator for ease of wiring. Insert the corresponding wire into
the quick connects and tighten by turning the screw.
Mode of Operation:
1. Upon initial field installation the capacitor requires a full charge,
up to 35 seconds, before the valve starts to turn. Charging time
will vary (typically less) during normal operation.
2. When the capacitor is charging the green LED light will FLASH.
3. Once the capacitor is charged, the green LED will stop flashing
but remain ON. At this point the valve’s actuator will rotate the
ball valve. The green LED will remain ON as long as the ther-
mostat is calling (the unit is powered).
4. Once the thermostat is satisfied the green LED will turn OFF and
the valve will rotate 90° into its normal position or non-powered
position. For example: If the actuator is an NC (normally closed)
version, the actuator would open the valve when the thermostat
calls. Once the thermostat is satisfied the actuator would then
rotate the valve 90° to its normally closed position.
Multi-status LED and Troubleshooting:
This troubleshooting table is intended as a helpful guide and is not all inclusive. There could be other causes and solutions for a non-
functioning product.
LED STATUS INDICATES POSSIBLE CAUSE POSSIBLE SOLUTION
Not Illuminated Power off
No call
No Power
Verify there is a call.
Check for voltage at the actuator.
Steady blink (once per
second)
Charging
Solid Power on
Slow blink (once every
5 seconds)
Excessive
charging time
Not enough VA
Reset the actuator (see note).
Use a larger VA transformer or add an additional transformer.
Too many valves per transformer
Reduce the number of valves.
Use a different thermostat.
Double blink (twice
every 5 seconds)
Excessive
opening time
Obstruction in valve
Buildup of contamination in valve
Reset the actuator (see note).
Remove obstruction.
Clean the valve and/or system.
Replace valve.
Failed actuator Replace Actuator.
NOTE: Reset the actuator by removing power for 5 seconds and then restoring power.

ARNING: Do not use zone valves on indirect
water heaters without a tempering device.
CAUTION: Do not jumper power/motor (24 VAC)
connection terminals, even temporarily. This may
cause damage to the thermostat’s heat anticipator.
