Ports to connect to on The Attendant:
HEATERS: H1- H5 on The Attendant or H1 – H2 on The Attendant Mini
Heat pumps, Heaters, and Chillers require a Water Temp Sensor wired to one of the Temp Sensor ports in order for the attendant to control the device.
These devices should only be powered directly from the power center or breaker panel. Do not run electricity through a relay as The Attendant will control the device to turn on/off by using the communication cable.
DO NOT Connect the remote wiring to a RS485 BUS terminal. It will cause irreversible damage to the circuit board.
Nirvana Heat pumps can only be controlled using legacy Dry Contact connections. This connection type allows The Attendant to control the heat pumps on/off state to manage the desired water temperature set point.

Connect a two-wire 22 AWG conductor cable to the middle and right P/S terminals on the Nirvana Heat Pump control board located in the main electrical box.
Connect the other end of the cable to an open heater port on The Attendant. Refer to the diagram below.
