Includes everything what is needed, not only panel that will not work alone (ebay case).
The principe of an automatic climate control is: it lets to keep the interior temperature constant - exactly llike VW Klimatronic. You set for example 22 celcius degrees on the panel, if it is colder outside it will heat up to 22 degrees but no more, if it is cooler outside it will descend the temp to 22 degrees, but not less). The normal climate control does not have this functionality, it gives cold / hot only without measuring the tepmerature conditions. That's why on one glider there is a celcius scale... from 20 to 30 degrees :)
If the air flow direction AUTO button is pressed, the microprocessor selects the best direction to blow air to achieve the optimal settings. In other words it selects where to blow itself. This can be overrided by selecting another button, for example blow to the legs.
Idem for fan speed control - if set to AUTO position the fan speed changes itself.
The sliders are electronic not mechanical as in case of an manual climate control panel. The fan speed changes freely, not only 0-1-2-3 speed position. It is because a power transistor is used, commanded via the control unit, not a simple 3 position resistor, commanded by a simple switch.
This climate control does not use metal control cable to command hot / cold mixer, it is entirely electrically motorised.
The auto climate harness that is included just replaces the manual climate harness. The plugs that connect it to the car main harness are exactly the same as manual climate ones, there are just 4 wires more, going to the front exterior air temperature sensor (mounted behind the radiator) and interior air temp sensor (under rear right speaker - there is a small grille for this). This plug is located on the pillar, behind the glovebox, in proximity of check engine connector.So all electrical job to make it working is to swap the manual harness with an automatic one and to pull 2 wires from the plug to the front of the car and 2 wires to the rear speaker.
Mechanically the only problem to solve is to add the air mix servomotor to the usdm heater box. On prelude it is easily achieved just by mounting this servomotor upside down - I can provide the pictures how it is done. On del sol it will be a similar operation.
The kit contains:
1. Control unit with AUTO mode
2. Air mix servomotor
3. Heater core temp sensor
4. Interior air temp sensor
5. Exterior air temp sensor
6. Sun beam sensor
7. Evaporator temp sensor
8. Power transistor for blower
9. High speed relay for blower
10. Whole undomaged uncut original electrical harness.
Very rare item, especially being 100% complete kit
Looking for around 280 euros.
