Setting The Chiller Setpoint - Christie CineLife+ RGB PLF Installation And Setup Manual

Setting the chiller setpoint

The chiller setpoint represents the temperature of the coolant that is supplied to projector.
The default chiller setpoint temperature is 24°C. The default setting addresses many typical projection
booth conditions, ensuring maximum projector brightness and operating efficiency.
If room temperatures or relative humidity are allowed to rise, the maximum power setting available
for the lasers is reduced and brightness is decreased as a result.
The projector is equipped with sensors that monitor ambient temperature and humidity. When selecting
the chiller setpoint, use the actual temperature and relative humidity of the projection booth expected
during operating conditions. Selecting a setpoint that does not reflect actual show environment
conditions may result in a sub-optimal projection image.
1. Use the reference chart below to determine the coolant temperature required for your site.
2. On the Y axis of the chart, find the Maximum Room Temperature expected in the projection
booth.
3. On the X axis of the chart, find the Maximum Room Relative Humidity.
4. To identify the correct chiller setpoint temperature, find the intersection of the two rows.
Choosing a chiller setpoint temperature that falls outside the green area means that projector
brightness is reduced.
5. On the projector touch panel, select Laser Settings > Laser Power/LiteLOC Setup, and
follow the steps for creating a new laser file, including setting the chiller setpoint value.
