 | Controls up to 5 compressors with one or two suction pressures. |
| Controls screw, recips, or rotary compressors in any combination. |
| Automatically sequences compressors to their most efficient combination to
save energy. |
| Automatically keeps the compressors operating near full capacity to save
energy. |
| Controls up to 2 different suction control set points at different times of day. |
| Starts, stops, loads, and unloads compressors. |
| Suction pressure control within 1 PSIG of the set point. |
| Unloads compressors as high discharge safety pressure is approached. |
| Discharge pressure shuts down on high discharge safety. |
| Displays compressor suction set point at whatever value you choose. |
| Displays current compressor suction operating pressure. |
| Displays compressor suction deadband at whatever value you choose. |
| Displays compressor suction minimum operating pressure set point. |
| Displays compressor manual or automatic control status. |
| Displays acceptable power outage time for auto restart. |
| Displays daily pressure offset times to control 2 separate daily suction set points. |
| Displays the compressor sequence and load percent capacity status. |
| Alarms on safety control set point violations. |
| Alarms on high suction trap liquid level and shuts down compressors of affected stage. |
| Monitors your ammonia sniffer and shuts down compressors if leak is in the eng. room. |
| Adjusts for non-linear slide valve capacity. |
| Logs compressor run time hours and alerts for planned maintenance. |
| Monitors system kWh usage. |
| Simple for operator to change compressor control parameters. |
| Monitors and displays ambient temp, relative humidity, discharge pressure and condensate
liquid temp. |
| Floats head pressure to lowest optimum operating pressure to save energy. |
| Controls up to 8 water pumps or fans. |
| Calculates and displays ambient Wet Bulb Temp. |
| Displays and controls on difference between dry bulb and wet bulb temps. |
| Has manual or automatic operation feature, displays difference between actual and
saturation pressure , letting you know if air is in system. |
| Allows operator to make changes to the pump and fan sequence. |
| Allows operator to set the minimum operation discharge pressure set point. |
| Automatically raises discharge pressure set point for defrost cycle. |
| Has adjustable dead band and step delay set point to avoid excessive fan cycling. |
| Shuts down compressors when high discharge safety pressure is reached. |
| Simple for operator to change all condenser control parameters. |
| Minimum pump operation temp protects against freeze-ups. |
| Ladder Logic portion can be used for miscellaneous control, such as pump packages,
lighting, floor warming, battery chargers, water chemistry control, etc. |
| OMNI has 16 digital inputs and 16 analog inputs that can be used to control
16 digital outputs using ladder logic. |
| Analog and digital inputs from compressor and condenser portion can also be used in logic. |
| Ladder logic can use counting in logic. |
| Ladder logic can use delays and time of day in logic. |
| Ladder logic can use separately displayed adjustable set points in logic. |
| Logic is written in easy to use English language tables. |
| Three pages of logic tables are available in password protected region. |
| 16 internal flags and 16 counters are available for use in logic. |
