HVAC_Coil (FB) ¶ FUNCTION_BLOCK HVAC_Coil HVAC heater/cooler coil. Functionality ¶ HVAC_Coil provides a control strategy for a HVAC (heater / cooler) coil taking into account: differential pressure monitoring fan request The fan is requested if: it is enabled (xEnable = TRUE) differential pressure monitor is detecting proper differential pressure (xDifferentialPressureMonitor = TRUE) setpoint reaches/exceeds fan request threshold (rSetpt >= rFanReqTreshold) The fan request involves a stop delay. In case the differential pressure monitor is not detecting proper differential pressure, this is signaled by xError=TRUE / eErrorID=HardwareError. InOut: Scope Name Type Initial Comment Input xEnable BOOL TRUE Enable rSetpt REAL 0.0 Setpoint, 0..100(%) rFanReqTreshold REAL 0.0 Fan request threshold, 0..100(%) xDifferentialPressureMonitor BOOL TRUE Differential pressure monitor - TRUE => signaling proper differential pressure tFanStopDelay TIME TIME#0ms Fan stop delay xReset BOOL FALSE Reset itfDateTimeProvider Util.IDateTimeProvider Globals.g_dtpDateTimeProvider Source for the current date and time information in milliseconds since 1.1.1970 00:00:00.000 Output xOn BOOL Coil is switched on. xFan BOOL Fan request xError BOOL Error indication eErrorID Error Error ID Methods: SetError Structure: SetError (Method)

HVAC_RotaryHeatExchanger (FB) ¶ FUNCTION_BLOCK HVAC_RotaryHeatExchanger HVAC rotary heat exchanger. Functionality ¶ HVAC_RotaryHeatExchanger provides a control strategy for a HVAC rotary heat exchanger taking into account: control of bypass damper differential pressure monitoring optional cleaning operation malfunction detection malfunction locking operational time The heat exchanger is requested if: it is enabled (xEnable = TRUE) setpoint reaches/exceeds request threshold (rSetpt >= rReqTreshold) optional cleaning operation ¶ If the rotary heat exchanger had not been enabled for a given time (tCleanMaxOff) it is enabled and set to rCleanPos for tCleanTime. malfunction detection ¶ If a hardware malfunction is detected via hardware error indication (input) or differential pressure monitor xError is set to TRUE, eErrorID is set to Error.HardwareError. malfunction locking ¶ Malfunction locking makes the difference how to handle / recover from a detected hardware malfunction. Malfunction locking enabled (xMalFuncLock := TRUE): If a malfunction is detected, the rotary heat exchanger (xOn) is shut off. If the hardware malfunction is gone, xError / eErrorID and rotary heat exchanger shutoff are kept until a reset (xReset := TRUE). Malfunction locking disabled (xMalFuncLock := FALSE): If a malfunction is detected, the rotary heat exchanger (xOn) is NOT shut off. The rotary heat exchanger recovers from a hardware malfunction automatically. InOut: Scope Name Type Initial Comment Input xEnable BOOL TRUE Enable rSetpt REAL 0.0 Setpoint, 0..100(%) rReqTreshold REAL 0.0 Request threshold, 0..100(%) xDifferentialPressureMonitor BOOL TRUE Differential pressure monitor - TRUE => signaling proper differential pressure tCleanMaxOff TIME TIME#2880m0s0ms Maximum off time to enable cleaning operation tClean TIME TIME#0ms Cleaning operation duration, set to T#0S to disable cleaning operation rCleanPos REAL 100.0 Cleaning operation setpoint, 0..100(%) - 0% => closed, 100% => open xErri BOOL FALSE Error indication - rotary heat exchanger is signaling an error xMalFuncLock BOOL FALSE Enable the malfunction locking xOpTimeInit BOOL FALSE Initialize the operational time with a given value (tInit). tOpTimeInit LTIME LTIME#0ns Initialization value xReset BOOL FALSE Reset itfDateTimeProvider Util.IDateTimeProvider Globals.g_dtpDateTimeProvider Source for the current date and time information in milliseconds since 1.1.1970 00:00:00.000 Output xOn BOOL Rotary heat exchanger is switched on, bypass dampers closed rSetptOut REAL Actual setpoint tToNextClean TIME Remaing time to next clean operation tOpTime LTIME Operational time xError BOOL Error indication eErrorID Error Error ID Methods: SetError Structure: SetError (Method)
