Certain system compressors may stall in the event of a restart within the two-minute period
with EnviroStart fitted. These are generally, but not always, systems with a mechanical
thermostat fitted. If you experience problems with the unit re-starting in such conditions then
use the inbuilt timer feature of EnviroStart by switching DIP 6 into the "ON" position. This will
cause the unit to always wait two minutes before a restart is allowed ensuring backstop
pressures are equalized within the compressor circuit. (Default value is "OFF").

Illuminates when unit is powered and ready to operate,
indicates that initialisation self test has been completed. When
flashing it indicates that the two minute "delay-start" timer,
(enabled through DIP Switch 6), is running. The flashing light
will stop as the motor starts after the two minute period.
Illuminates when a fault condition is detected by the control
software. This light may flash periodically as the system
operates, indicating that a temnporary "stall mode" has been
detected. This is normal and is quite acceptable.
