Scheduling Standalone HyperStat Split

| Overview

The HyperStat Split now support Real-Time Clock (RTC) functionality and scheduling capabilities, even in standalone mode. This means you can configure time-based:

• Setpoints

• Fan operations

• Operating modes

The process involves the following steps:

• Setting up Real Time Clock (RTC) on  HyperStat Split

• Create scheduled events for weekdays.

• Create scheduled events for weekends.

| Setting Up Real Time Clock (RTC)

To set up the Real Time Clock (RTC)

• On the home screen of your yperStat Split device:

• Press the + & - buttons together to navigate to the inputs screen.

• Press the next button to navigate to the Installer options screen.

• Press the down arrow button to navigate to the Set Device Time option.

• Press the select button to access the Set Device Time option.

• Press the down arrow button to access the Day of the week.

• Use the down arrow button, or the slider to set the day of the week.
• Press the right arrow button to access the hour and digits of minute option as below

• Use the down arrow button, or the slider to set the hour and minutes for the device.
• Press the SET button to confirm the scheduled event.

| Setting Up Schedule Events

From the installer option screen

• Press the down arrow button to navigate to the Set Schedule option.

• Press the select button to access the Set Schedule option.

• Press the down arrow button to navigate to the Weekday Scheduling option.

• Press the select button to access the weekday scheduled events.

• Press the down arrow button to access any schedule events.

• Press the select button to configure the schedule event.

• Press the down arrow button to access configurable options.

• Press the select button to configure values for the configurable options.

• Use the down/ Up arrow button, or the slider to set the values.
• Press the Deselect button to confirm the value configured.
• Repeat the steps to set the value for other configurable options, as below.

• As shown below, repeat the steps to set up the weekend event schedule.

• Repeat steps to set the value for other options under a weekend schedule event, as below.

Note: An event will remain active until a new event overrides it. This applies to both weekday and weekend schedules.

| Applicable Modes

The Table below is a better illustration of the mode applicable:

| Recirc Fan

The recirc fan is a minimum fan speed that remains operational even when no conditioning is occurring. This is enabled or disabled by setting the option to ON or OFF.

| Ventilation

The Ventilation in the standalone HyperStat Split is mapped to Exhaust fan control, and is enabled or disabled by setting the option to ON or OFF.

The Exhaust Fan control operates as shown below when enabled.

Controlled by the economizing loop output, with multiple stages activating at predefined threshold levels.

• Stage 1 activates when the economizing loop output reaches 50% (default).

• Stage 2 activates when the economizing loop output reaches 90% (default).

These activation thresholds are configurable using:

• Exhaust Fan Stage 1 Threshold (%)

• Exhaust Fan Stage 2 Threshold (%)

To avoid frequent ON/OFF cycling of the exhaust fans, a hysteresis is applied. The hysteresis value defines how much the economizing loop output must fall below the activation threshold before the corresponding exhaust stage turns OFF. This can be configured using the Exhaust Fan Hysteresis (%) parameter.

Example (Default Hysteresis = 5%):

• Exhaust Fan Stage 2 deactivates when the economizing loop output drops below 85% (90% − 5%).

• Exhaust Fan Stage 1 deactivates when the economizing loop output drops below 45% (50% − 5%).
