WARNING: Wiring connections must be made in accordance with all applicable electrical codes.
WARNING : To prevent electrical shock, disconnect electric power to system at main fuse or circuit breaker box until
installation is complete. When a service switch is installed, more than one disconnect switch may be required to
deenergize this device for servicing.
Geo-Sentry Zone Valve Wiring Diagrams:
NOTE: Some power robbing thermostats require the use of a resistor (always use the resistor provided by the ther-
mostat manufacturer with the Zone Sentry). Consult the thermostat instructions for the resistor installation.

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.
