Freon sensor parameters with an asterisk * are shown only when the Freon sensor type
“Gauge” or “Both” is selected.
Water sensor parameters with number sign # are shown only when the water sensor type
“Gauge” or “Both” is selected.
Brightness
OLED display brightness may be set from 4 to 15.
Screen saver brightness
Screen saver is activated after 3 minutes without a button press. The OLED brightness
during screen saver may be set from 0 to 8.
Service high limit
The high limit sensor measures the water temperature leaving the electric heater. If the
temperature measured by the sensor exceeds this set temperature in heat mode, the stage
will stop heating and the display will indicate a “High Limit” fault. Temperature values
may be set from 100 to 145 °F (37.8 to 62.8 °C).
Current limit (Future Option)
This parameter sets the maximum allowable stage or compressor current. The optional
current sensor must be installed when using this parameter. Current values can be set
from 5 to 50 amps in 5 amp steps. The default value is off.
