| Sequence of Operation

The sequence of operation is completely driven based on Occupancy mode, Space Current Temperature, and the set Cooling and Heating Desired Temperatures.

Let us understand the Sequence of operations based on the occupancy modes, and how the other factors contribute to the sequence of operations during different types of occupancy modes.

Note: The humidity level for the system is either the average level reported by all the zones serviced by the RTU/AHU.

| Controls & Triggers Strategy

Controls	Trigger Strategy
Cooling Stages	Cooling stages trigger when the zone demands cooling, based on the current temperature. The cooling stages switch ON based on the cooling loop output, whose values are scaled for the different stages. And switches off based on conditioned current temperature values.
Heating Stages	Heating stages trigger when the zone demands to heat, based on the current temperature. The heating stages switch ON based on the heating loop output, whose values are scaled for the different stages. And switches off based on conditioned current temperature values.
Fan Stages	Fan stages trigger based on the fan loop output which is a result of cooling loop and heating loop outputs, during cooling and heating operation respectively. Fan control configured as modulating using analog out the percentages for the low, medium, and high are altered to 30% 60%, and 100% respectively.
Fan Enable	Fan enable is a provision introduced to enable additional fan control, which switches "ON" during the occupied schedule, and when any conditioning is happening during the unoccupied schedule. Example: Fan Enable is used in a modulating VFD-controlled fan, where the variable frequency drives need to be switched "ON" before ramping up and down the fan speeds. It can also be put to use for additional fan control within a staged HVAC unit or a zone, which should remain "ON" during their occupied hours. Note: Fan Enabled is not a control option for the Fan stages. the fan stages control needs to be mapped separately for the system to start conditioning.   When the Fan Enabled is configured alongside the AnalogOut-based Staged fan speeds, or staged fan speeds on other relays. The Analog Out minimum Fan, or the relay for minimum Fan speed is turned ON even when the fan loop output is <10% without considering the relay activation hysteresis.
Occupied Enable	A relay mapped to Occupied Enable is "ON" whenever the zone is in an occupied schedule and "OFF" when any conditioning happens during an unoccupied schedule.
Humidifier	A Relay mapped to the humidifier is turned on whenever the humidity level for the CPU drops below the target Minimum Inside Humidity, a tuner value.  And shows the user a target humidity control in Zone Screen on CCU and Facilisight portal
De Humidifier	A Relay mapped to the dehumidifier is turned on whenever the humidity level for the CPU goes above the target Minimum Inside Humidity, a tuner value.  And shows the user a target humidity control in Zone Screen on CCU and Facilisight portal
Demand Control Ventilation (DCV)	The DCV control is used to control an independent damper for the ventilation of air into the zone.  based on the following additional parameters set during configuration. zoneCO2DamperOpeningRate    zoneCO2Threshold zoneCO2Target This allows for very granular control of the IAQ. It is driven or triggered by the DCV Loop Output which is a resultant of the above-configured parameters. Example: During an occupied time If the Zone CO2 value > zoneCO2Threshold then DCV damper control triggers based on the DCV loop output. If the Zone CO2 value < zoneCO2Threshold there will be no DCV damper trigger, and the relay will be set to OFF.
Door/Window Sensing	The door/window sensors are used to automatically override the operation of a zone, for the presence of doors and windows in the zone, Where the door/window can be opened and there can be a loss of the actual conditioning that is in effect. The Door or Window sensor can be a Thermistor Input or Analog Input. If the Door Sensor is a Then Thermistor Input A resistance is detected, based on which the zone operations are overridden. If the resistance detected is less than 10,000 ohms, the door is in closed condition, and the zone enters the door/window closed state. If the resistance detected is more than 10,000 ohms the door is in open state condition, and the zone enters the door/window open state, during which the heating, cooling, and demand ventilation are turned off. Analog Input A voltage is detected, based on which the zone operations are overridden. If the Voltage detected is less than 2.0V the door is in closed condition, and the zone enters the door/window closed state. If the Voltage detected is more than 2.0V the door is in open state condition, and the zone enters the door/window open state, during which the heating, cooling, and demand ventilation are turned off. When the door is open and the zone is occupied or unoccupied the zones operate as per the table below. If the zone is occupied If the zone is unoccupied Conditioning is turned off. The minimum fan speed configured in the profile is enabled. When there is active conditioning: The minimum relay-based Fan/ Min Analog fan speed / Analog Out 2 at Recirculate is enabled. When there is no active conditioning: Fan Stages and Control stages are disabled.     Note: If this option is enabled by the user, this affects the conditioning status of the entire zone if multiple modules are paired in the zone.  An Autoaway trigger induced by a door/window sensor overrides desired temperature limits at level 8, coming from level 3 by the Autoaway setback value.  An Auto Forced Occupied trigger induced by a door/window sensor overrides the Auto away setback or building setback temperature limits at level 8, coming from level 3 to the desired temperature limits (e.g., 70-74) For more information refer to Effects of the Schedules in the Buildings
Keycard Sensor	The Keycard sensors are also used to automatically override the operation of a zone, where when the key card is removed from the keycard slot in a room/zone, which means the occupant of the room is no longer in the room leading to loss of the actual conditioning that is in effect. Up to one keycard sensor can be connected for a zone. When the Keycard sensor is a part of the Analog IN, a Voltage is detected, based on which the zone operations are overridden. If the Voltage detected is less than 2.0V the Keycard switch is closed and the card is in the slot, And the zone operates normally during an occupied schedule time. or the zone enters into auto force occupied if the zone is in unoccupied schedule time. If the Voltage detected is more than 2.0V the Keycard switch is opened and the card is not in the slot, And the zone enters into unoccupied from forced occupied if the zone is in unoccupied schedule time. or zone enters into Key card auto away if the zone is in occupied schedule respectively. For more information on the keycard sensor working refer HyperStat Installation Note:  Keycard functioning is separate from the "Auto Away" toggle. There is no interlinking between keycard-based functioning and Occupancy sensor-based functioning. An Autoaway trigger induced by a key card sensor, overrides desired temperature limits at level 8, coming from level 3 by the Autoaway setback value.  An Auto Forced Occupied trigger induced by a key card sensor overrides the Auto away setback or building setback temperature limits at level 8, coming from level 3 to the desired temperature limits (e.g., 70-74) For more information refer to Effects of the Schedules in the Buildings
Current Transformer	Current transformer is another analog input option in the profiles for HyperStat, it connects to a transformer in the circuit and simply measures the current consumption in the circuit. For more information on the current transformers as Analog IN refer HyperStat Installation

| Important Pointers

• When the Fan Enabled is configured alongside the AnalogOut-based Staged fan speeds, or Relay-based fan speeds.

  The minimum Fan speed in an Analog-based fan configuration, or low fan speed in a Relay-based fan configuration is turned ON when the Fan loop output is <10% without considering the relay activation hysteresis.

When the Door/Window sensor is enabled, A Minimum fan speed is operated when the door/window is open, and conditioning will be OFF.

• In an Analog-based fan configuration, the Fan is operated at the AnalogoutatMin, and in a staged fan speed configuration the Fan is operated at the AnalogOutatRecirculate speed. 
• A tuner parameter Minfanruntimepostconditioning defines the period for which the Last known fan speed, in an Analog-based fan configuration / minimum fan speed in a Relay-based fan configuration, needs to run after the conditioning is turned off.

Test Signal

This is used for troubleshooting and testing the equipment if the configuration and the field setup are in sync, and the device is communicating properly with the controlled equipment. Also at any point, you can override the value of the output the algorithm decides. 

We can use the test signal for relays to turn them on or for analog out to ramp up and see if the equipment works according to commands from the device.

Test Signal Time Out

once enabled it will be active for an hour if the screen is not changed, after an hour of no interaction on the screen.  zone screen displays and the test signal will be OFF.

If the screen changes from the test signal configuration screen it will be timed out in one minute (time for the algorithm to run next).

Note: The test signal for modulating output is in deci volts, ranging from 0.0dV to 100.0dV.
