What is the maximum wire distance for connecting valves to the 27894 timer?

If the distance between the sprinkler timer and valves is under 700 feet (210 meters), use Orbit sprinkler wire or 20 gauge (AWG) plastic jacketed thermostat wire. If the distance is over 700 feet (210 meters), use 16 gauge (AWG) wire. For best results in wet environments like valve boxes, use Orbit Grease Caps to prevent corrosion and protect against water infiltration.
