Drivers of the Hispacold climate control unit, often found in vehicles like the Irizar i6, frequently encounter issues with its screen brightness. Many users have reported difficulties dimming the backlight of the unit, especially for night-time driving. While the dashboard dimmer typically adjusts the brightness of most controls and displays, it often does not affect the climate control unit. Below is a compilation of tips and suggestions shared by drivers to tackle this challenge.
Common methods to address brightness issues
1. Using the unit’s settings:
According to the Hispacold manual, the control unit allows adjustments for contrast but does not provide an explicit option for changing screen brightness. The following key combinations can be used:
- (2+8) for greater brightness
- (2+7) for less brightness
- (3+8) for greater contrast
- (3+7) for less contrast
- (2+3) to reset factory settings for brightness and contrast
However, several users have noted that these combinations may not resolve the issue entirely, particularly if the screen remains overly bright at night.
2. Physical solutions:
Since the settings are often limited, many drivers have resorted to creative physical modifications to reduce the brightness:
- Window tint film: Applying a small piece of window tint film over the screen has been a popular choice. It is easy to apply and effectively dims the screen without causing damage.
- Black cardboard or tape: Thin black cardboard or blue tape can be cut to size and temporarily fixed over the display using Blu Tack or similar adhesive. This method is reversible and highly affordable.
3. No backlight issue:
Interestingly, some users have reported an opposite issue where the backlight on their unit does not work at all. While this avoids the brightness problem, it can make the screen difficult to read, particularly during the day.
Additional considerations
Dash dimmer limitations:
The dashboard dimmer switch, which adjusts the brightness of most vehicle controls, does not seem to incorporate the climate control unit in certain models. Drivers are advised to check their vehicle’s manual or consult with a technician to confirm if the dimmer is connected to the climate control display.
Maintenance tips:
- Check the pollen filter: Regularly ensure that the vehicle’s pollen filter is clear, as this can impact the overall performance of the climate control system.
- Thermostat functionality: Faulty thermostats can affect the climate control system’s heating capabilities, as shared by one user who noted that their vehicle barely produced heat due to a malfunctioning thermostat.
Conclusion
While the Hispacold climate control unit offers some flexibility with contrast adjustments, its lack of brightness settings can be inconvenient for drivers. Simple physical modifications like using window tint or black cardboard are effective and low-cost solutions to dim the display. Incorporating these tips can make night-time driving more comfortable without straining the eyes. For persistent issues, consulting with a technician or exploring potential upgrades may be worthwhile.
