Response Delay Values are:
No Delay (default), 1, 2, 5, 10, 15, 20, 30, 60 seconds.
SET TEMP UNITS
Choose to display temperature values in Celsius or Fahrenheit (default Celsius)
Note that temperature settings must be entered in Celsius.
SET TEMP RANGES
Set three temperature trigger points for Bottom, Top and Trip temperatures, in °C.
SET TEMP LOWER (minimum temperature to be maintained)
(default 0°C, permissible range 0-10°C).
SET TEMP UPPER (maximum desired temperature)
(default 40°C, permissible range 35-50°C).
SET TEMP TRIP (temperature at which load will be isolated – see note)
(default 60°C, permissible range 55-70°C).
Note: A thermal emergency is when enclosure ventilation fails with the lamp on, in which case the
temperature will rise very quickly. To avoid nuisance tripping we recommend setting a higher Trip
temperature, 60°C or above.
SET MAX HUMIDITY
(default 80%, permissible range 50-90%).
Set target maximum relative humidity level. This should be set at or a few % higher than the
normal high humidity levels expected on site.
SET LAMP ON POINT
The lamp current at which DEC detects the luminaire/luminaire lamp is running. Default is 1 Amp,
which allows for equipment fans and power supplies to run without changing the air in the
enclosure. Lamp on point may be set in 0.2 Amp increments between 0.2 Amps and 2.0 Amps.
RESET LAMP HOURS
Reset each time you change the lamp in the luminaire/luminaire.
Make this a part of your maintenance instructions.
STATUS DISPLAY
View current status information, using the arrow keys to scroll through:
a) Humidity – relative humidity in %
b) Air temperature, in degrees C or F
c) PCB temperature (this will usually be significantly higher than air temperature)
d) Voltage – line Voltage reaching the DEC
e) Current being drawn by luminaire/light, in Amps
