Page 31: Compressor Protection - (Hpc, Dtl Or Aux Switch Proving Trip)
Compressor Protection – (HPC, DTL or Aux switch proving trip) Compressor protection operates similar to Reliatel-based solutions, with some minor changes/additions. In most cases, action is taken on a per-circuit basis, but often we have protection devices per compressor. Each compressor output will have a corresponding Compressor Proving input, which will be monitored to determine the state of the compressor contactor (via Auxiliary switch).
Page 32: Compressor Protection - Low Pressure Cutout Control
For each compressor/circuit, a Normally CLOSED low pressure cutout input will be monitored for equipment protection on the Symbio 700. When a low pressure event is active, the input will become OPEN and diagnostics will be generated as described below.
Page 33: For Heat Pump Units In Active Mechanical Heating And Outdoor Air Temperature ≥ 0°F
For Heat Pump Units in Active Mechanical Heating and Outdoor Air Temperature ≥ 0°F If a compressor low pressure cutout input opens: All Compressor Outputs on the effected circuit will be immediately Commanded OFF. The “Circuit X LPC Trip” diagnostic point will be annunciated. The Circuit will be disabled for 3 minutes.

Supply Air Tempering Supply Air Tempering Operation If the Supply Air Tempering function is configured and the Discharge Air Temperature local sensor is valid, the Space Temperature Control algorithm manages the Supply Air Tempering function to prevent excessively cold discharge air from being supplied from the unit. The sequence for VVZT systems are consistent with CVZT systems, utilizing single-speed, and full airflow operation.

Use-cases for this may include optimizing humidity control sequences per-application or to meet certain product- level specifications.
Page 72: Supply Fan Speed Control
When a system is equipped with a VFD, the minimum and maximum VFD parameters can be adjusted to tune the airflow to meet the application requirements. In addition to this, the Symbio 700 supports setpoints that can be used to adjust airflow as needed: Supply Fan Maximum Speed Setpoint...
Page 73: Supply Fan Minimum Speed Setpoint
Supply Fan Minimum Speed Setpoint Range: 0-100% Operation: 0-100% over minimum to effective maximum VFD configured fan speed Example: VFD Min = 30Hz, Effective VFD Max = 60Hz Supply Fan Minimum Speed Setpoint @ 50% yields 45Hz VFD output. Minimum and Maximum Speed Setpoints interact to ensure that the minimum defined fan speed at a given equipment operating condition is maintained.

The Symbio 700 configuration and settings can be “backed-up” to a file on a USB drive connected to the Symbio 700. If a USB drive is connected to the Symbio 700, the “Backup” process can be initiated through the Mobile Service Tool Once Complete, a Backup (.tgx) file will be placed onto the USB...
Page 116: Restore
Restore If a USB drive is connected to the controller, with a valid controller “Backup” file installed, the user can initiate the “Restore” process through the Mobile Service Tool Restoring a Backup will apply all configuration and controller settings from the “Backup” file to the controller. When the restore is complete the user is disconnected from the controller and taken to the unit list.
Page 117 Restore To Factory Defaults (Baseline Backup) At time of manufacture, a “Baseline Backup” of the Symbio 700 is created. This backup contains the same information as a normal backup but it can’t be removed from the controller and it can’t be overwritten.
Page 118: Update Firmware
Scan For Firmware Firmware Update Similar to restoring a controller “Backup” file to the Symbio 700, the user can initiate a Firmware Update from the Mobile Service Tool. A valid firmware file must be in a USB drive connected to the Symbio 700.

Page 158: Odyssey Refrigeration Miscellaneous Info
Odyssey Refrigeration Miscellaneous Info. Microchannel Heat Exchanger Condensers (MCHE) This design improves heat transfer and the refrigerant that enters the coil quickly turns to liquid. The MCHE tube volume holds very little refrigerant, so the refrigerant charge of the system is reduced. However, the tube volume is so small that if the flow of refrigerant out of the MCHE condenser is slowed much more than the flow of refrigerant into the MCHE condenser, the condenser may quickly fill with liquid and cause a high-pressure control trip.

- like 100% OA - then the system must be designed to support HGBP. As an example, the line lengths are limited to 75 feet. For more information, please reference Trane Application Guide Hot Gas Bypass Installation Guidelines for Direct Expansion (DX) Equipment, APP-APG017-EN.

Unit Charging The charging charts below lists Refrigerant Charge and Base matched unit charge. Refrigerant Charge is for exactly 25 feet of line length. (Chart Note 1) Base matched unit charge is for 0 feet of line length (Chart Note 2) For example using this chart Base charge 5.2, Ounces per foot 1.15 Distance between units 15 feet, (15 X 1.15) /16 = 1.08 lbs + 5.2 = 6.28 lbs.
