Beware that in case of high pressure switch failure the safety valves will trip andhot refrigerant will be ejected at high pressure!Once tripped, the software will get back to normal operation. However, the alarm will not be reset until the highpressure switches are manually reset through the button included in the switch.4.12.2 Calibrate SensorsSetpoint/Sub-Menu Default Range DescriptionUnit  - Submenu for Unit calibrate sensorCircuit #1  - Submenu for Circuit 1 calibrate sensorCircuit #2  - Submenu for Circuit 2 calibrate sensor4.12.2.1 Unit Calibrate SensorsThis page allows a proper calibration of the unit sensorsSetpoint/Sub-Menu Default Range DescriptionEvap LWT= 7.0°C Evaporator LWT current reading (includes the offset)Evp LWT Offset= 0.0°C Evaporator LWT calibrationEvap EWT= 12.0°C Evaporator EWT current reading (includes the offset)Evp EWT Offset= 0.0°C Evaporator EWT calibrationOutside Air= 35.0°C Outside Air Temperature current reading (includes the offset)OAT Offset= 0.0°C Outside Air Temperature calibrationHR Ewt= 40.0°C Heat Recovery EWT current reading (includes the offset)HR Ewt Offset= 0.0°C Heat Recovery EWT calibrationHR Lwt= 45.0°C Heat Recovery LWT current reading (includes the offset)HR Ewt Offset= 0.0°C Heat Recovery LWT calibrationSwitch Box T 40.0°C Switch Box Temperature current reading (includes the offset)HR Ewt Offset= 0.0°C Switch Box Temperature calibrationCommon LWT 8°C Common LWT current reading Includes the offsetComm LWT Offset= 0.0°C Common LWT calibration4.12.2.2 Circuit Calibrate SensorsThis page allows to adjust the sensors and transducers readings.
