Follow the steps below to set each of the active zones as Critical or Non-critical zone.
By default, all zones are critical.
1. Turn the thermostat
ON
.
2. Press and hold both the [+] and the [-] buttons simultaneously for 10 seconds.
3. Choose the required zone using the [Select] button. Selected zone number will appear on display
and the heater icon will flash.
4. Use the [+] button to set zone as Critical zone (“ON” will appear on display).
5. Use the [-] button to set zone as Non Critical zone (“OFF” will appear on display).
6. Repeat steps above 3 to 5 for any required zone.
7. Press and hold both the [+] and the [-] buttons simultaneously again for 5 seconds to return to
normal display.
Note: Critical zones will participate in the staggering scenario as long as it is snowing.
Once the snowing stopped, the system will continue staggering between critical zones for 3 more
cycles and then switch to staggering between the non-critical zones for the rest of the “time delay
before stopping the heaters” set by parameter P04.
Example:
- Zones 1,2,3,4
enabled
- Zones 1,2
Critical
- Zones 3,4
Non-critical
- Sequencing logic 1+3 together, 2+4 together
- Time delay before stopping the heaters: P04 = 9 hours.
- Splitting time: P06 = 120 minutes.
