It is done by pushingBS2.Accessing the selected setting's value isdone by pushing BS3 1 time.To quit and return to theinitial statusPress BS1.Changing the value of theselected setting in mode 2▪ Once mode 2 is selected (push BS1for more than 5 seconds) you canselect the wanted setting. It is doneby pushing BS2.▪ Accessing the selected setting's valueis done by pushing BS3 1 time.▪ Now BS2 is used to select therequired value of the selected setting.▪ When the required value is selected,you can define the change of valueby pushing BS3 1 time.▪ Press BS3 again to start operationaccording to the chosen value.6.2.7 Mode 1: Monitoring settingsIn mode 1 (and in default situation) you can read out the followinginformation:Value / DescriptionH2P Shows the present operation state.OFFNormal operation state.ONAbnormal operation state.FLASHINGUnder preparation or under test preparationValue / DescriptionH6P Shows the status of low noise operation.OFFUnit is currently not operating under low noiserestrictions.ONUnit is currently operating under low noiserestrictions.Low noise operation reduces the sound generated by theunit compared to nominal operating conditions.Low noise operation can be set in mode 2. There are twomethods to activate low noise operation of the compressorunit and heat exchanger unit.▪ The first method is to enable an automatic low noiseoperation during night time by field setting. The unit willoperate at the selected low noise level during theselected time frames.▪ The second method is to enable low noise operationbased on an external input. For this operation an optionalaccessory is required.H7P Shows the status of power consumption limitation operation.OFFUnit is currently not operating under powerconsumption limitations.ONUnit is currently operating under powerconsumption limitation.Power consumption limitation reduces the powerconsumption of the unit compared to nominal operatingconditions.Power consumption limitation can be set in mode 2. Thereare two methods to activate power consumption limitation ofthe compressor unit.▪ The first method is to enable a forced power consumptionlimitation by field setting. The unit will always operate atthe selected power consumption limitation.▪ The second method is to enable power consumptionlimitation based on an external input. For this operationan optional accessory is required.6.2.8 Mode 2: Field settingsPress the BS2 button to make field settings to configure the system. The LEDs give a binary representation of the setting/value number.Setting(= binary)ValueDescriptionFan high static pressure setting.In order to increase the static pressure the outdoor unit fan isdelivering, this setting should be activated.(default)Deactivated.Activated.Automatic low noise setting and level during night time.By changing this setting, you activate the automatic low noiseoperation function of the unit and define the level of operation.Depending on the chosen level, the noise level will be lowered.(default)DeactivatedLevel 1 Level 3Level 2Level 3
