2. Intended Use

The KONVEKTA air conditioning unit is an air conditioning system that works with the ozone friendly refrigerant R134a and which creates a pleasant and individually adjustable room temperature by means of forced convection. The determined use includes also the observance of the operating instructions as well as the proof of regular inspections.

2.1. Operating Conditions

NOTE: KONVEKTA uses components made of copper and aluminum, which last a whole unit lifetime under normal environmental conditions. Should the units be operated under aggressive environmental conditions, i.e. air containing salt-, phosphate- or ammoniac extremely, a corrosion of the cupper- and aluminum components cannot be ruled out. The cupper- and aluminum components of the KONVEKTA systems are not suitable for such extreme application conditions. We indicate emphatically, that corrosion is not subject to warranties for defects. KONVEKTA does not take over any warranties for defect, neither for corrosion nor for consequential damage resulting there from, nor for damages caused by cleaning the systems with highly compressed or corrosion advancing substances.

3. Control unit KS60

The air conditioning control KS60 is a control and regulation device for air conditioners in modern buses. The bus driver is relieved from all questions of an optimum air conditioning in the passengers’ compartment by a simple and clear handling. All functions of the a/c unit are adjustable by different key-buttons. Every button has an indicating lamp, called LED used as a control function of the buttons or in case of operating. LED is shining red if button is pressed or if unit is in operation. Control board KS60 is connected onto the original dash board lightning of the vehicle. This means that in case of running vehicle lamp, night lightning of control board (LED green) is also activated.

☛

Note:

We recommend driving with automatic mechanism (Key S5, see 4.1).

Additionally to the automatic the following functions can be activated: a) SMOG -flap manually, in order to prevent the entrance of exhaust fumes (in tunnels) b) REHEATfunction to dehydrate the steamed up wind shield

3.1.1. Auto-test

If voltage supply to unit is interrupted, unit starts a self test immediately after reset. Here all entrances and exits are controlled:

Process of auto test will be show at the display:

1. Indication of all LED’s and display indication:

4.3. Adjustment of temperature

If a/c-unit is operating, vehicle inside temperature can be adjusted with key or , in a range of 16°C up to 28°C. In case of operating key (+) or (-), temperature can be increased or reduced.

The actual temperature can be read on display.

4.4. Recirculated Air operation → only in case of a/c units with Rec. air flaps option

In case of recirculated air operation (key S6 activated), the income of fresh air is interrupted and the air inside the vehicle is going to be circulated which avoids that outside air, possibly dirty because of exhaust fumes (tunnel driving) has a chance to penetrate into interior room of the vehicle.

Starting of the recirculated air operation , press key S6, the LED-display will light up. This position should not be adjusted very long. If windows are misting up, return air operation should be switched off:

If key S6 is pressed again the return air flap will be reactivated and fresh air operation restarted.

The LED-display will go out .

Automatic In case of a temperature difference of more than 5°C between the set temperature

(adjusted value) to the existing temperature the return air flaps switch to recirculated air operation.

Manual If the button S6 is pressed, the recirculated air function of the return air flaps will be maintained independently from a temperature difference.

4.5. REHEAT activate / stop

=> Only for units with heating option

Switching on of the air-conditioning system via button S5 afterwards the key S5 will be pressed shortly twice (double click). REHEAT will be activated for a period of 20 minutes, the LED-display will light up at the same time.

⇒ Operation of the blowers at the highest speed level by key S3 (increase of the air flow output)

⇒ Recirculated air operation must be switched off.

The premature termination of the REHEAT is possible by double-pressing the key S5.

4.6. Display of air duct temperature

=> Only for units with heating option

While pressing buttons S1 and S6 actual air duct temperature is displayed for 2 seconds.

4.7. Indicate outside temperature => only in case of a/c units with heating option

=> Standard for units with heating, optional for units without heating starting software version 3

While pressing buttons S1 and S4 actual outside temperature is displayed for 2 seconds.
