Before connecting any type of sensor, be sure the controller has been powered down.

Status Sensor

The Lynx SmartHub controller is designed to accept both a normally-open and normally-
closed status switch. For axample, a pressure switch may be connected to this sensor input
to detect pressure over a maximum value.
1. Route the status switch cable into the controller.
2. Connect the cable wires to the status switch terminals labeled A in Figure 11.
3. Place the controller's switch to ON.

Rain Sensor

LSM systems can use either a rain bucket or a normally-open / normally-closed rain
switch. GAC systems can use only a normally-open / normally-closed switch.
1. Route the rain sensor's cable into the controller.
2. Connect the cable wires to the Rain Sensor Terminals labeled B in Figure 11.
3. Place the controller's switch to ON.

Flow Sensor

LSM systems can use either a Badger Meter / Data Industrial series 200 insertion type flow
sensor or a Bermad 900 series flow meter.
1. Route the flow sensor's cable into the controller.
2. Connect the cable wires to the Pressure Sensor Terminals labeled C in Figure 11.

3. Place the controller's switch to ON.

Master Valve / Pump Relay

The Lynx SmartHub provides an output to control a master valve or pump relay. The
output is active when any station is on, and off otherwise. Stations defined as switches do
not cause the output to activate.
1. Connect the Positive/Hot wire of the power source that controls the master valve or
the pump relay to the Master valve/Pump relay switch terminal. See Figure 11, D.
2. Route another wire from the Master Valve / Pump terminal and connect it to the
master valve solenoid or pump relay.
3. Connect the Negative/Equipment ground wire of the power source to the master
valve solenoid or pump relay.
4. Place the controller's switch to ON.
