Extensive motor and electrical testing on the Carrier units has ensured that the full horsepower range of the motor can be utilized with confidence. Using fan motors up to the horsepower ratings shown in the Motor Limitations table will not result in CONTROLS QUICK START The following section will provide a quick user guide to setting up and configuring the P Series units with ComfortLink controls. See Basic Control Usage section on page 3 for information on operating the control. Variable Air Volume Units Using Return Air Sensor or Space Temperature Sensor — To configure the unit, perform the following: 1. The type of control is configured under Configuration UNITC.TYP. Set C.TYP to 1 (VAV-RAT) for return air sensor. Set C.TYP to 2 (VAV-SPT) for space temperature sensor. NOTE: For VAV with a space sensor (VAV-SPT), under ConfigurationUNITSENSSPT.S, enable the space sensor by setting SPT.S to ENBL. NOTE: Configuration of the machine control type (C.TYP) has no effect on whether a unit has a VFD or just a supply fan installed for static pressure control. No matter what the control type is, it is possible to run the unit in either CV or VAV mode provided there are enough stages to accommodate lower air volumes for VAV operation. Refer to the section on static pressure control for information on how to set up the unit for the type of supply fan control desired. 2. The space temperature set points and the supply air set points are configured under the Setpoints menu. The heating and cooling set points must be configured. See the Heating Control and Cooling Control sections for further description on these configurations. Configure the following set points: OHSP Occupied Heat Set point OCSP Occupied Cool Set point UHSP Unoccupied Heat Set point UCSP Unoccupied Cool Set point GAP Heat-Cool Set point Gap V.C.ON VAV Occupied Cool On Delta V.C.OF VAV Occupied Cool Off Delta 32 nuisance tripping or premature motor failure. Unit warranty will not be affected. 2. All motors comply with Energy Policy Act (EPACT) Standards effective October 24, 1997. Also configure the following points in the Configuration D.LV.T menu: L.H.ON Demand Level Low Heat On L.H.OF Demand Level Low Heat Off 3. To program time schedules, make sure SCH.N=1 under ConfigurationCCNSC.OVSCH.N to configure the control to use local schedules. 4. Under the TimeclockSCH.L submenu, enter the desired schedule. See Time Clock section for further descriptions of these configurations. 5. Under ConfigurationSPSP.SP, the Supply Duct Static Pressure set point should be configured. 6. If supply air temperature reset is desired, under the ConfigurationEDT.R submenu, the following set points should be configured: RS.CF EDT Reset Configuration RTIO Reset Ratio LIMT Reset Limit RES.S EDT 4-20 mA Reset Input This applies to both TSTAT MULTI and SENSOR MULTI modes. NOTE: Configure either RTIO and LIMT or RES.S. All three are not used. 7. See the Economizer Options section on page 33 for additional economizer option configurations. 8. See the Exhaust Options section on page 33 for addition exhaust option configurations. Multi-Stage Constant Volume Units with Mechanical Thermostat — To configure the unit, perform the following: 1. Under ConfigurationUNITC.TYP, set C.TYP to 3 (TSTAT MULTI).
2. Under the Setpoints menu, set the following configurations: SA.HI Supply Air Set Point Hi SA.LO Supply Air Set Point Lo 3. See the Economizer Options section on this page for additional economizer option configurations. 4. See the Exhaust Options section on this page for additional exhaust option configurations. Multi-Stage Constant Volume Units with Space Sensor — To configure the unit, perform the following: 1. Under ConfigurationUNITC.TYP, set C.TYP to 4 (SPT MULTI). 2. Under the Setpoints menu, the following configurations should be set: SA.HI Supply Air Set Point Hi SA.LO Supply Air Set Point Lo 3. Under the Setpoints submenu, the heating and cooling set points must be configured: OHSP Occupied Heat Setpoint OCSP Occupied Cool Setpoint UHSP Unoccupied Heat Setpoint UCSP Unoccupied Cool Setpoint GAP Heat-Cool Setpoint Gap D.LV.T Cool/Heat Set Point Offsets (located in the Configuration menu) 4. Under ConfigurationUNITSENSSPT.S, enable the space sensor by setting SPT.S to ENBL. 5. Under ConfigurationUNITFN.MD, set FN.MD to 1 for continuous fan or 0 for automatic fan. 6. To program time schedules, set SCH.N=1 under ConfigurationCCNSC.OVSCH.N to configure the control to use local schedules. 7. Under the TimeclockSCH.L submenu, enter the desired schedule. See Time Clock section for further descriptions of these configurations. 8. See the Economizer Options section below for addition economizer option configurations. 9. See the Exhaust Options section below for addition exhaust option configurations. Economizer Options — Under the Configuration ECON submenu, the following set points should be configured: EC.EN Economizer Enabled? EC2.E Econ Act.2 Installed? EC.MN Economizer Min.Position EC.MX Economizer Maximum Position E.TRM Economizer Trim for SumZ? E.SEL Econ Changeover Select OA.E.C OA Enthalpy Change Over Select OA.EN Outdoor Enthalpy Compare Value OAT.L High OAT Lockout Temp O.DEW OA Dew Point Temp Limit ORH.S Outside Air RH Sensor 33 ConfigurationECONEC.MN should always be set for the minimum damper position. If the unit is equipped with an outdoor air flow station, the following points in ConfigurationECONCFM.C need to be set. OCF.S Outdoor Air CFM Sensor O.C.MX Economizer Minimum Flow O.C.DB Economizer Minimum Flow Deadband If equipped with an outdoor flow station, make sure ConfigurationECONCFM.COCF.S is enabled. If an outdoor air cfm station is used, then the economizer will control to cfm, not a position, as long as the sensor is valid. Therefore, ConfigurationECONCFM.CO.C.MX supersedes ConfigurationECONEC.MN. Indoor Air Quality Options DEMAND CONTROL VENTILATION — Under ConfigurationIAQDCV.C, the following configuration parameters should be set to establish the minimum and maximum points for outdoor air damper position during demand control ventilation (DCV): EC.MN Economizer Min.Position IAQ.M IAQ Demand Vent Min.Pos. O.C.MX Economizer Min.Flow O.C.MN IAQ Demand Vent Min.Flow ConfigurationIAQDCV.CIAQ.M is used to set the absolute minimum vent position (or maximum reset) under DCV. ConfigurationIAQDCV.CEC.MN is used to set the minimum damper position (or with no DCV reset). This is also referenced in the economizer section. ConfigurationIAQDCV.CO.C.MX is used only with the outdoor airflow station and will supersede ConfigurationIAQDCV.CEC.MN as long as the outdoor air cfm sensor is valid. ConfigurationIAQDCV.CO.C.MN is used only with the outdoor airflow station and will supersede ConfigurationIAQDCV.CIAQ.M as long as the outdoor air cfm sensor is valid. Exhaust Options — The following exhaust options should be configured. EXHAUST TYPE UNIT Modulating Power Exhaust S.O. VFD* High- Capacity Power Exhaust† Return Exhaust† 48/50P2,P4 X S.O.
