For complete information on the FX10 Control, refer to submittal Data SD1981 and Application Guide AGFX10. Power Fail Restart/Random Start Delay When the controller is first powered up, outputs are disabled for a random start delay time to prevent simultaneous starting of multiple heat pumps. The default time period for the start delay will be random between 1 and 120 seconds. Compressor Fixed On Delay Time The Compressor 1 Fixed "On" Delay Time will ensure that the compressor output (B02) is not enabled for () seconds after the control receives a call to start compressor 1. The compressor 2 Fixed "On" Delay Time will ensure that the compressor 2 output (B04) is not enabled for (1) minute after the control receives a call to start compressor 2. Compressor Minimum Run Time and Off Time The compressor will operate for a minimum of 2 minutes (except high-pressure and emergency shutdown). The minimum compressor "Off" time is 4 minutes. Compressor Stage Lead Lag The compressor lead lag option and number of run hours can be enabled using the factory setup software, a facility management system, service/commissioning tool, or a user interface. The factory default is 24 hours. Heating Cycle Compressor 1 will turn on after accessory outputs 1 and 2 have been enabled, the low pressure switches have been verified, and the fixed compressor start delay timer has been satisfied. Compressor 2 will be sequenced as needed to maintain the heating set point. Cooling Cycle The reversing valves will be "On". Compressor 1 will turn on after accessory outputs 1 and 2 have been enabled, and the low pressure switches have been verified. Compressor 2 will be sequenced as needed to maintain the cooling set point. Emergency Shutdown This mode is activated by a command from a facility management system or a closed contact on BI-2. All outputs will be turned off immediately and will remain off until the emergency shutdown mode is de-activated. Lockout Mode This mode is activated by any of the following fault signals: refrigerant system high/low pressure, and cooling freeze protection.
