Manual Heater Operation
(-02 Housings Only)
The heater in the outdoor dome:
- Automatically turns on when temperature inside
the housing drops below 18°C (64°F)
- Automatically turns off when the temperature
inside the housing goes up to 23°C (73°F).
The heaters can be manually controlled to clear fog
or light condensation, or to accelerate frost or ice
removal from the outside of the bubble.
To Clear Fog or Light Condensation
To clear trapped fog or small amounts of
condensation inside the housing bubble, turn on
Output/Auxiliary 3 (cycled high/low mode) to
operate the heaters at two temperature ranges for
23-minute cycles for 3 hours 23 minutes unless
manually turned off.
To turn on Output/Auxiliary 3, enter 3 and press
Output On. To turn off, enter 3 and press Output
Off. Refer to controller/matrix switcher instructions
for information about controlling outputs/auxiliaries.
To Accelerate Frost or Ice Removal
IMPORTANT! This procedure cannot be used on
domes using the Manchester protocol. Manchester
does not support latching Auxiliary 4. Only cycled
High/Low mode is available. Attempting to use
Auxiliary 4 results in turning off Auxiliary 3.
To accelerate frost or ice removal from the housing
bubble, turn on Output/Auxiliary 4 (continuous high
mode) to operate the heaters at high temperature
for 3 hours 23 minutes unless manually turned off.
To turn on Output/Auxiliary 4, enter 4 and press
Output On. To turn off, enter 4 and press Output
Off. Refer to controller/matrix switcher instructions
for information about controlling outputs/auxiliaries.
Command Priority
If both commands to control the heaters are issued
in sequence, the first command runs to completion
(3 hours 23 minutes), then the second command
runs.
For example, the command to run the heaters on
continuous high mode is issued (Output/Auxiliary 4
On). Five minutes later, the command to run cycled
high/low mode is issued (Output/Auxiliary 3 On).
The heaters will run on continuous high for 3.4
hours. After that time, the cycled high/low mode
starts and runs for 3.4 hours.
How Heater Modes Operate
The difference between cycled high/low mode and
continuous high mode is explained as follows:
Cycled high/low mode. High mode heats to 45°C
(113°F) ±3°. Low mode heats to 23°C (73°F) ±3°.
The graph below illustrates cycling by showing
three heating cycles.
- Cycle 1 (high mode). The heater is on as long
as temperature is less than 45°C. When
temperature rises above 45°C, the heater turns
off. This cycle continues for 23 minutes.
- Cycle 2 (low mode). The heater turns on when
temperature drops below 23°C. When
temperature rises above 23°C, the heater turns
off. This cycle continues for 23 minutes.
- Cycle 3. High mode repeats for 23 minutes.
High /low cycling continues for 3 hours 23 minutes,
unless manually turned off. After that time, the
heater automatically turns off regardless of
temperature, and remains off until manually turned
on.
Continuous high mode. For protocols supporting
it, Output/Auxiliary 4 turns on the heaters in
continuous high mode. Continuous high mode
heats the dome up to 45°C (113°F) ±3° for 3 hours
23 minutes, unless temperature exceeds 45°C or
the heater is manually turned off.
