  • Page 13: Startup Sequence

    Startup Sequence Under normal conditions, the Symbio 700 will startup over approximately 60 seconds once power is applied to the system. During this process, the controller checks that a valid system configuration is present and proceeds to normal control operation. After startup, the system will begin to respond to operational requests.

  • Page 14: Conventional Thermostat Sequence Of Operation

    Conventional Thermostat Sequence of Operation When the Odyssey system is configured to operate with a conventional thermostat, the controller provides protection for the system (see General Support Sequence section) and continues to provide insight to operating conditions. A conventional thermostat can be applied with constant volume cooling only, heat pump, and single zone 2-speed fan configured systems.

  • Page 20: Compressor Low Pressure Cutout Control

    For each compressor/circuit, a normally CLOSED low pressure cutout input is monitored for equipment protection on the Symbio 700. When a low pressure event is active, the input becomes OPEN and diagnostics are generated as described below. Refer to the Diagnostics section below for specific diagnostics that are generated based on the circuit Low Pressure Cutout inputs.
