Weathermatic Smartline® Controllers

Modern irrigation controllers can detect a shorted solenoid and bypass the affected zone. Since Irrigander expanders drive the controlled solenoids directly there is never an issue with an Irrigander expander activating the controller's over current circuit. However the Weathermatic Smartline® controller also detects an open solenoid circuit. Early versions of Irrigander expanders did not present the same load as a solenoid so the Weathermatic Smartline controller interpreted the Irrigander expander connection as an open circuit and registered a fault. We developed the Irrigander Controller Adapter to correct this issue. The Irrigander Controller Adapter presents enough of a load to the Weathermatic Smartline controller to allow the zones controlled by the Irrigander expander to operate correctly without affecting normal controller operation. See the table below for Irrigander expander models affected by this issue:

 
Irrigander Model Serial Numbers Affected
Irrigander 2 Splitter Model not affected
Irrigander 4 Expander Model not affected
Irrigander 8 Expander Serial numbers earlier than 902029
Irrigander 4/8 Expander Serial numbers earlier than 903011
Irrigander 8 Pro Expander Serial numbers earlier than 711018
Irrigander 4/2 Pro Expander Serial numbers earlier than 802015
Irrigander 8/2 Pro Expander Serial numbers earlier than 712020
 
The model and serial number can be found on the label on the side of the Irrigander expander Encoder unit. Models with serial numbers newer than those listed in the table above incorporate input circuitry that imitates a solenoid allowing the Irrigander expander to work properly with the Weathermatic Smartline® controller without the adapter. We will provide the Irrigander Controller Adapter to any customer who has an Irrigander expander model affected by this issue.
