Move DIP switch S1 located on the side of thermostat to ON position.
Adjust the temperature set point.
Above this temperature the outputs to the heaters will not be activated.
Adjust and enable/disable the low limit temperature.
When temperature on snow sensor drops below the low temperature limit, the
heating system will stop.
Adjust and enable/disable the upper limit temperature, and display
temperature on heaters sensor.
Note: If the upper limit control is disabled, the heaters will work regardless of
the upper limit.
Adjust the time delay before stopping the heaters.
Note 1. The time delay countdown will start when the snow detection signal
from snow sensor will switch from positive to negative.
Note 2. The staggering sequence will continue during the time delay period.
Adjust the “Manual ON” mode time period.
The delay time parameter defines a time frame in which the heaters remain
ON after receiving a “Manual ON” command.
Adjust the splitting time. The heaters cycle / splitting time parameter defines
the full cycle working time of all the heaters when working in sequence.
Adjust the snow sensor sensitivity value
(20% - Less sensitive, 80% - more sensitive)
Select the number of PYROSENSE snow sensors connected.
Turn ON test conditions to check the functionality of the system regardless of
sensors parameters. Use some water to wet the circuit on top of the snow
sensor. Note: If the technician did not manually exit test/commissioning mode,
the unit will automatically return to normal mode after 5 hours.
Move DIP switch S1 located on the side of thermostat to OFF position.

Important: Make sure the unit is turned OFF (the word
“OFF” should appear on display).
Move DIP switch S1 to ON position.
Press and hold the [ON] button for 10 seconds.
Move DIP switch S1 back to OFF position.
DIP switch S2 - Short measuring times (test only)
- “ON” - Short measuring times – for test/commissioning only
(measuring times will be divided to 60).
- “OFF” - Normal operation.
Short measuring times: A real 1 hour will take 1 minute and a
real 1 minute will take 1 second.
DIP switches S3 and S4 – heaters sequencing logic
Use DIP switches S3 and S4 to define the sequencing logic of
the heater (zones) as follows:
All 4 outputs work per request from the snow sensor(s)
Outputs 1+3 and outputs 2+4 work together (by splitting time)
Note: Do not use this configuration with more than two snow
sensors connected.
Outputs 1,2 and 3 work in sequence (by splitting time) and
output 4 works continuously.
Note: Do not use this configuration with more than two snow
sensors connected.
All 4 outputs work in sequence (by splitting time)
Note: Do not use this configuration with more than two snow
sensors connected.
Note: if output 5 is set to work together with outputs 1-4, (see
“Heater output no. 5 logic” in the technician settings), it will
operate the same as output 4.
Enable/Disable zones

While OFF, press both the [+] and [-] buttons for 10 sec.
Press the [Select] button to select zone.

Adjust the threshold.
If the threshold is not reached, the logic of turning the heaters either ON or
OFF will not be affected by snow detection.
During countdown to threshold time, the snow flake icon will flash.

Important: Changes made to technician parameters will not take effect
as long as DIP switch S1 is in ON position.
