CSB A3 Feedback Alarm (CS.A3) — This configuration is used to enable or disable the compressor A3 feedback alarm. This configuration must be enabled whenever A3.EN is enabled. CSB B1 Feedback Alarm (CS.B1) — This configuration is used to enable or disable the compressor B1 feedback alarm. This configuration must be enabled whenever B1.EN is enabled. CSB B2 Feedback Alarm (CS.B2) — This configuration is used to enable or disable the compressor B2 feedback alarm. This configuration must be enabled whenever B2.EN is enabled. CSB B3 Feedback Alarm (CS.B3) — This configuration is used to enable or disable the compressor B3 feedback alarm. This configuration must be enabled whenever B3.EN is enabled. Capacity Threshold Adjust (Z.GN) — This configuration provides an adjustment to the SUMZ Cooling Algorithm for capacity control. The configuration affects the cycling rate of the cooling stages by raising or lowering the threshold that demand must build to in order to add or subtract a stage of cooling. Normally this configuration should not require any tuning or adjustment. If there is an application where the unit may be significantly oversized and there are indications of high compressor cycles, then the Capacity Threshold Adjust (Z.GN) can be used to adjust the overall logic gain. Normally this is set to 1.0, but it can be adjusted from 0.1 to 10. As the value of Z.GN is increased, the cycling of cooling stages will be slowed. Compressor Lockout Temperature (MC.LO) — This configuration defines the outdoor air temperature below which mechanical cooling is locked out. Lead/Lag Operation? (LLAG) — This configuration selects the type of lead/lag compressor operation for the unit. There are 3 choices: automatic, circuit A, and circuit B. 0 = AUTOMATIC If this configuration is set to “AUTOMATIC”, every time cooling capacity drops to 0%, on the next call for cooling, the control will start up the first compressor on the circuit that did not start on the previous cooling cycle. 1 = CIRCUIT A If this configuration is set to “CIRCUIT A”, every time cooling capacity drops to 0%, a circuit A compressor is always the first to start on the next call for cooling. 2 = CIRCUIT B If this configuration is set to “CIRCUIT B”, every time cooling capacity drops to 0%, a circuit B compressor is always the first to start on the next call for cooling. NOTE: If the unit is configured for a Digital Scroll (ConfigurationCOOLDG.A1 = YES) or Minimum Load Valve (ConfigurationCOOLMLV = ENABLE), then circuit A is always the lead circuit regardless of the setting of this configuration. This configuration must be set to 1 (CIRCUIT A) for size 30 to 60 units if an accessory low ambient operation Motormaster ® V control is installed on the unit. If the unit is configured for the Humidi-MiZer ® adaptive dehumidification system, then circuit B automatically becomes the lead circuit when the unit enters into one of the Humidi- MiZer modes (dehumidification or reheat). The unit will immediately start a circuit B compressor when a Humidi-MiZer mode is initiated. MotorMaster Control? (M.M.) — The condenser fan staging control for the unit is managed directly by the ComfortLink controls. There is no physical Motormaster device in the standard unit. This configuration must be set to YES if an accessory low ambient operation Motormaster V Control is 46 installed on the unit. Setting this configuration to YES alters the condenser fan staging sequence to accommodate the Motormaster V control. See Head Pressure Control section, page 53, for more information. Maximum Condenser Temp (SCT.H) — This configuration defines the saturated condensing temperature at which the head pressure control routine will increase an outdoor fan stage. The saturated condensing temperature of either running circuit rising above this temperature will increase a fan stage. If the outdoor air temperature is greater than 72 F, then no outdoor fan staging will occur, and the outdoor fan stage will default to the maximum stage. Minimum Condenser Temp (SCT.L) — This configuration defines the saturated condensing temperature at which the head pressure control routine will decrease an outdoor fan stage. The saturated condensing temperature of both running circuits decreasing below this temperature will decrease a fan stage. If the outdoor air temperature is greater than 72 F no outdoor fan staging will occur, and the outdoor fan stage will default to the maximum stage. A1 is Digital Scroll (DG.A1) — This configuration instructs the unit controls as to whether the A1 compressor is a digital scroll or regular scroll compressor. If set to YES, the compressor will be controlled by the compressor staging routine and SUMZ Cooling Algorithm. A1 Min Digital Capacity (MC.A1) – This configuration defines the minimum capacity the digital scroll compressor is allowed to modulate to. The digital scroll compressor modulation range will be limited from MC.A1 to 100%. Dig Scroll Adjust Delta (DS.AP) – This configuration defines the maximum capacity the digital scroll will be allowed to change per request by the SUMZ Cooling Algorithm. Dig Scroll Adjust Delay (DS.AD) – This configuration defines the time delay in seconds between digital scroll capacity adjustments. Dig Scroll Reduce Delta (DS.RP) – This configuration defines the maximum capacity the digital scroll will be allowed to decrease per request by the SUMZ Cooling Algorithm when OAT is greater than ConfigurationCOOLDS.RO. This ramped reduction is only imposed on a decrease in digital scroll capacity. An increase in capacity will continue to follow the value defined by ConfigurationCOOLDS.AP. Dig Scroll Reduce Delay (DS.RD) – This configuration defines the time delay, in seconds, between digital scroll capacity reduction adjustments when OAT is greater than ConfigurationCOOLDS.RO. This ramped reduction is only imposed on a decrease in digital scroll capacity. An increase in capacity will continue to follow the value defined by ConfigurationCOOLDS.AD. Dig Scroll Reduction OAT (DS.RO) – Under certain operating conditions, a sharp decrease in digital scroll capacity can result in unstable unit operation. This configuration defines the outdoor air temperature above which a reduced capacity (ConfigurationCOOLDS.RP) and time delay (ConfigurationCOOLDS.RD) will be imposed on a digital scroll capacity reduction. This ramped reduction is only imposed on a decrease in digital scroll capacity. An increase in capacity will continue to follow the values defined by ConfigurationCOOLDS.AP and ConfigurationCOOLDS.AD. Dig Scroll Max Only OAT (DS.MO) – This configuration defines the outdoor air temperature above which the digital scroll will not be allowed to modulate. The digital scroll will be locked at 100% above this outdoor air temperature. Min Load Valve Enable (MLV) – This configuration instructs the control as to whether a minimum load valve has been installed and will be controlled by the compressor staging routine.
High SST Alert Delay Time (H.SST) — This option allows the low saturated suction temperature alert timing delay to be adjusted. Reverse Rotation Verified? (RR.VF) — This configuration is used to enable or disable the compressor reverse rotation detection algorithm. This algorithm performs a check for correct compressor rotation upon power up of the unit. The method for detecting correct rotation is based on the assumption that there will be a drop in suction pressure upon a compressor start if it is rotating in the correct direction. A test is made once, on power up, for suction pressure change on the first compressor of the first circuit to start. Reverse rotation is determined by measuring suction pressure at 3 points in time: • 5 seconds prior to compressor start. Table 33 — Setpoints Table 34 — Supply Air Reset Configuration Table 35 — Cooling Configuration 47 • At the instant the compressor starts. • 5 seconds after the compressor starts. The rate of suction pressure change from 5 seconds prior to compressor start to compressor start (rate prior) is compared to the rate of suction pressure change from compressor start to 5 seconds after compressor start (rate after). If (rate after) is less than (rate prior minus 1.25), alarm A140 is generated. This alarm will disable mechanical cooling and will require a manual reset. It is important to note that in Service Test mode reverse rotation is checked on every compressor start. Once it has been verified that power to the unit and compressors has been applied correctly and the compressors start up normally, this configuration can be set to YES to disable the reverse rotation check.
