S3 ON, S4 OFF
Outputs 1, 2 and 3 work in sequence (according to splitting time), and output 4 works continuously.
Note:
Do not use this configuration with more than two snow sensors connected.
S3 ON, S4 ON
All 4 outputs work in sequence (according to splitting time).
Note :
Do not use this configuration with more than two snow sensors connected.
Notes:
1.
The illustrations above show the heater operation for
PYROBOX5. The logic remains the same for PYROBOX3C,
without heaters 3 and 4, and for PYROBOX3, without
heater 4.
2.
Heater 5, for all models, will be activated with or without
heater 4, depending on the “Heater output logic” parameter
set in section P07.
3.
The logic will ignore disabled zones.
TEMPERATURE READING ERRORS
Ambient temperature sensor readings (on snow sensor) are outside reliable
measuring range.
Ambient temperature < -9°F/-23°C, ambient temperature > 54°F/12°C
The system will continue to operate using constant predefined values. In addition, the display
will alternate between “LO” and -11°F/-24°C for low temperature readings and between “HI”
and 55°F/13°C for high temperature readings.
“SensErr 1” will appear on the display.
If the system is configured to work with more than one snow sensor, the faulty snow
sensor number will appear on the display: P01, P02, P03 or P04.
The system will use readings from snow sensor 1 instead of the missing readings from
the faulty snow sensor.
