Citimarine Store is well known for Cruisair Parts, including the SMX II control system and keypads (SMX II AB, SMXir, SMXht).
If looking to purchase the SMX II Keypad, see here:
Here’s a bit about the Cruisair SMX II Control system…
SMX II Keypads and Control Systems
The Dometic Cruisair SMX II consists of a keypad/display and a power/logic circuit board in the A/C unit’s electrical box. The controls can be used with almost all Cruisair marine A/C systems, and several adapters are available to allow the different keypads to work with the different systems, as well as retrofitted to older models (as well as non-Cruisair A/C systems with the proper adapters!).
It is a sophisticated and highly effective A/C control, but very easy to use. Simply set the temperature you’d like, and sit back and relax…
Excellent temperature regulation ensures no wide swings in temperature (which is common with most other AC controls). The Cruisair SMX II system retains all of your settings, even if the power goes out.
Standard features of SMX II Keypads
- Easy to understand interface
- Large, clear digital display of temperature, operating functions and code warnings
- Small LED lights on keypad to show AC system’s mode and status
You can set to heating, cooling, or an automatic switch between both when day and night temperature differences are more extreme.
If you are going to leave your boat unattended for long periods of time, you can program the SMX II keypad to turn on periodically, in order to circulate and remove moisture from your boat.
Installing the SMX II Control
It is best to install your SMX II keypad and control on an interior, vertical spot with rear access for wiring. It operates on low voltage DC and is ignition-protected. The control components do not produce heat, so no need for ventilation.
There are currently 3 different Cruisair Keypads that work with the SMX II control system:
SMX II AB – the original SMX II keypad, used for many years and still very popular
SMXir – smaller than the SMX II AB, the Cruisair SMXir has a hinged cover and remote control (Works only with 6-pin Cable or adapter)
SMXht – European style control fits into decorative bezel and has many new features (Works only with 6-pin Cable or adapter)
We currently have the classic SMX II Keypad, here… We will have the SMXir and SMXht on our site shortly, but can order them for you at a discount directly from Cruisair, just give us a call at 1 (800) 766-5256 or email us at [email protected].
