5 Operating the system
NOTE If your air conditioner has a Shaded-Pole (SP) fan motor instead of a Split-Capacitor (SC) High-Velocity (HV) fan motor, you must program "SP" into parameter P-14 before operating the equipment. Refer to Changing parameters on page 5 to find out how to change the parameter setting.

5.2 Basic operation
| Mode | Explanation |
|---|---|
| Off mode | When the control is in off mode, all control outputs are turned off. The program mode can only be accessed from the off mode. |
| On mode | When the control is in on mode, the system runs according to the settings shown on the display. When the system is switched on, the settings and parameters resume based on those last stored when the unit was operating. |
| Automatic mode | In automatic mode the cabin temperature is maintained within a range of ±1.1 °C (2 °F) of the set point temperature by default. This set point temperature differential can be reduced to ±0.55 °C (1 °F). If the ambient temperature rises above the set point, the system starts cooling. If the ambient temperature drops below the set point, the system starts heating. In order for the system to switch from heating to cooling or from cooling to heating, the temperature has to rise or fall by double the set point temperature differential. |
| Cool mode | If the ambient temperature rises above the set point, the system starts cooling. There will be no heating while cool mode is active. |
| Heat mode | If the ambient temperature drops below the set point, the system starts heating. There will be no cooling while heat mode is active. |
| Moisture mode | Every four hours the system starts the fan to circulate the air for 30 minutes. After that, a cooling cycle is started until the room temperature is cooled down by 1.1 °C (2 °F) or until the cooling cycle has run for one hour. Starting with software revision B23, when in moisture mode, the system will also prevent the temperature from falling below a minimum temperature. The default setting for this minimum temperature is 10°C (50°F). The minimum temperature can be changed within the range of 4.4°C (39.9°F) to 23.9°C (75.0°F). |
| Program mode | The operating parameters can be adjusted for an efficient operation of the system within any installation. |
| Mode | Explanation |
|---|---|
| Automatic fan mode | The system chooses between the three available fan speeds based on the temperature differential between room temperature and set point. |
| Manual fan mode | The user can choose the desired fan speed between the three available fan speeds. |
| Fan-only mode | The fan operates for air circulation when no cooling or heating is desired. |
| Cycled fan operation | The fan only operates during the heating or cooling cycles. When used with an optional electric heater, the fan remains on for four minutes after the heater cycles off. |
| Symbol | Name | Explanation |
|---|---|---|
| ⏻ | Power button | Switch between on and off mode. |
| ▲ | Up button | Increase the set point temperature by one degree or change setting in programming mode. |
| ▼ | Down button | Decrease the set point temperature by one degree or change setting in programming mode. |
| ?️ | Fan button | Switch between automatic fan mode and the three manual fan speeds. |
| ⚙️ | Mode button | Select the operating mode when the system is in on mode. |
| Symbol | Name | Explanation |
|---|---|---|
| AUTO | Automatic mode | In automatic mode this LED is lit as well as either the heat mode LED or cool mode LED, depending on whether the system is in a cooling or heating cycle with the water valve opened. |
| ❄️ | Cool mode | The system is in cool mode or in a cooling cycle while automatic mode is active. |
| ☀️ | Heat mode | The system is in heat mode or in a heating cycle while automatic mode is active. |
| ? | Moisture mode | The system is in moisture mode. |
| Symbol | Name | Explanation |
|---|---|---|
| AUTO | Manual fan mode | The fan speed bars show the fan speed: • Upper bar: maximum fan speed • Middle bar: medium fan speed • Bottom bar: minimum fan speed. |
| AUTO | Automatic fan mode | The fan speed is chosen automatically based on temperature differential. |

6 Programming the control unit
6.1 Entering program mode
- Make sure the system is in off mode.
- Press ⏻.
- Press ⚙️.
- Press ▲.
- Press 1.
The display alternates between "P-1" and "95" (or a different number between "35" and "95"). This means the system is in program mode and the first parameter "P-1" can be changed.
6.2 Exiting program mode
If no button is pressed for 50 seconds, the system will exit program mode automatically. Press ⏻ to change back to off mode without waiting for 50 seconds.
6.3 Identifying the software version
Some software functions and programmable parameters are only available for specific software versions. You should therefore identify the software version of your control unit before starting to program it.
- Enter program mode. The display alternates between "P-1" and "95" (or a different number between "35" and "95").
- Press 1.
The software version (e.g. "B23") is displayed for 1 second before the system changes back to off mode.
6.4 Changing parameters
- Make sure the system is in program mode. (In program mode the parameter number (e.g. P-1) and the parameter setting are displayed alternately.)
- Use IMG to increase the parameter number or use button IMG to decrease the parameter number until you reach the parameter you want to change.
- Use ▲ and ▼ to change the parameter setting.
- Repeat these steps until all parameters have the desired settings.
The parameter settings have been changed. You can now proceed by exiting program mode (Exiting program mode on page 5) or by saving the settings as new default settings (Handling default settings on page 6).
6.5 Handling default settings
The system is delivered with the factory default settings listed in the table (Parameter overview on page 6).
You can adapt these settings to your system configuration and set custom default values. Note the custom default settings in the column "Custom".
6.5.1 Memorizing new program parameters
NOTE To return to the factory default settings, reset the parameter settings listed in Parameter overview on page 6 manually. Then save the settings as described below.
- Make sure the system is in program mode. (In program mode a parameter number (e.g. P-1) and the parameter settings are displayed alternately.)
- Make all the changes you want to save as new default settings.
- Simultaneously press buttons ▲ and ▼.
The current parameter settings are memorized as new default settings. The system exits program mode.
6.5.2 Restoring memorized default settings
NOTE To return to the factory default settings, reset the parameter settings listed in Parameter overview on page 6 manually. Then save the settings as described below.
- Make sure the system is in program mode (Entering program mode on page 5).
- Select P-15 (Changing parameters on page 5).
- Change the parameter setting to "rSt".
- Press 1 while "rSt" is displayed.
The last memorized default settings are restored. The system exits program mode and P-15 is set back to "nor" again.
