Astralpool IXI / Zodiac JXi User Interface Kit - R0591901 - Obsolete

Astralpool IXI / Zodiac JXi User Interface Kit - R0591901 - Obsolete

Obsolete: this part is no longer available. Superseded by this R0591900 here. 

This is the genuine Zodiac user interface kit, part number R0591901, for Astralpool IXI and Zodiac JXi gas pool and spa heaters. The same part fits both heater sizes, the 200 and the 370. On the parts diagrams it is item 3 on the electrical system diagram.

What This Part Does

The user interface is the control panel on top of the heater. Unless the heater is run from a remote controller, all operations are set up and programmed through it: the Pool, Spa and Menu buttons, the up and down buttons and the display (Astralpool IXI manual, section 9.7).

The heater jacket top kit, R0592400, is supplied without the user interface.

Frequently Asked Questions

Does it fit the Astralpool IXI as well as the Zodiac JXi?
Yes. The Astralpool IXI and the Zodiac JXi use the same part number, R0591901, for the user interface kit.

Does it fit both the 200 and the 370?
Yes. R0591901 is listed for both heater sizes, the 200 and the 370.

Is R0591901 still available?
No. The R0591901 user interface kit is obsolete and no longer available. Contact us with your heater's rating plate details (model, serial number and gas type) and we will check what can be supplied.

Can the heater be run from automation instead of its own control panel?
An Astralpool IXI can be controlled by a Viron Connect 10 through the IXI gas heater interface, part 14608. The IXI manual says that while an external controller is connected, the heater's own control panel functions are disabled.
