The Attendant controller controls legacy devices like single-stage pumps, multi-stage pumps, blowers, simple on/off lighting, and other simple power on/off devices by powering them on and off using one or more high-voltage relays.
Select the appropriate wiring for your device and it’s power requirements and then, using the mobile app, create or configure the device.
See the wiring diagrams that follow for both 120 VAC and 240 VAC:
120 VAC
240 VAC
240 VAC Dual- and Multi-Stage Pumps
The Attendant controller controls dual- and multi-stage filter pumps by using two high voltage relays (one for each stage). See the following wiring diagram:
A Note About Connecting Equipment via Communication Cables
Several pieces of equipment – like variable speed pumps and salt cells – will require you to connect these devices to the serial (BUS1-4) communication ports. This equipment will not be powered by the relays onboard The Attendant, so connect these devices directly to the electrical panel following the manufacturer’s instructions.
The Attendant controller comes with four communication (serial) bus connections that are used to control and monitor these types of devices. Typically one device is connected to one port, however, several models allow you to chain multiple, similar devices together into one channel. An example of how similar devices are wired follows on the next page.
It is important that you do not mix and match device types on a single communication bus when chaining. This can lead to unexpected equipment behavior or even malfunction. Device types can be defined as legacy Hayward pumps, Hayward HUA pumps, Pentair and Jandy pumps, Goldline-compatible salt chlorinators, Jandy RS-485 heaters, etc.
Example: single device connected to BUS1, chained devices connected to BUS2:
Some salt chlorinator products require a voltage be supplied via the communication bus connection in order to function properly. Please refer to the manufacturer’s documentation or check our website for a list of known salt chlorinators that require this.
