Remote Temperature and Device Settings

Remote Temperature Sensors and Devices are generally used to average temperatures between spaces and monitor additional temperature points within your HVAC system, or it can be used as a standalone temperature monitoring device. Also, additional remote input devices can be used detect occupancy, or door and window monitoring.

Note: If the master thermostat gets power-cycled, it may receive a new network address which breaks the link to the sensor until the sensor learns the new address of the thermostat. This process can take several hours. During this time, the thermostat will assume the door is closed and will operate normally.

Weighted Temperature Settings for a Single Remote Temperature Sensor

Weight is applied for calculating the average temperature between a remote device with a temperature sensor and the master thermostat, which controls the signal sent to the air handling unit.

Notice moving the slider left or right distributes the temperature weight by changing the percentage of weight that master thermostat or remote device with a temperature sensor has over their space temperatures.

If the goal is to average the temperature of two adjacent spaces to achieve comfort in both areas, start with both weights at 50%. If one area is too cool or too warm, adjust the weights accordingly.

0% and 100% Weight Distribution Settings

Note: When moving either the master thermostat slider, or remote device with a temperature sensor slider, to 100%, then other will automatically go to 0%.

Set the master thermostat sensor to 0% if you do not want to use its temperature reading for controlling the space temperature; however, if set to 0% the master thermostat will still internally record the space temperature.

If the master thermostat is set to 0% and the remote device with a temperature sensor to 100%, and the remote device with a temperature sensor becomes unreachable for any reason (i.e., batteries are drained), the master temperature, which is still recording its own room space temperature, will use its internal temperature sensor and setpoints to take control of the HVAC system.

Disabled Setting

By moving the slider to the far left, this will disable the master thermostat’s internal temperature sensor completely. This means that the master thermostat is not sending any signals to air handling unit for heat, cool, or ventilation since it has no temperature reference in the event the remote device with a temperature sensor becomes unreachable. Also, an alarm notification will sent because space temperature can no longer be found.

Note: Only the master thermostat can be set to Disabled.

  • If the master thermostat is installed in an undesirable location (i.e., a cold basement), and by setting the master thermostat to Disabled we safeguard against the risk of the master thermostat taking control of the HVAC system should the remote device with a temperature sensor ever becomes unreachable.

    • By setting the master thermostat to Disabled instead of 0%, this will prevent the master thermostat from over-conditioning where the unreachable remote device with a temperature sensor is located. If the master thermostat were set to 0%, it would sense its less-than-ideal room temperature location and unsuccessfully is try to achieve temperature setpoint based on its location.

    Weighted Temperature Settings for Multiple Remote Temperature Sensors

    Weight is applied for calculating the average temperature between multiple remote devices with a temperature sensor and the master thermostat.

    Notice moving the slider left or right distributes the temperature weight by changing the percentage of control that master thermostat or remote temperature sensor has over their space temperatures. The average temperature and the remote devices with temperature sensors are displayed on the Thermostat’s History Graph.

    Tip: A maximum of eight (8) remote devices with temperature sensors can be associated with one master thermostat.

    If we have four (4) remote devices with temperature sensors (each set to 25%) associated with a single master thermostat (set to 0%) each remote device is providing space temperature feedback to that master thermostat. The average temperature of the four (4) space temperatures is 0.25 x (space temperature) and add all four values together for the average temperature.

    Remote Temperature Reading Only

    If a remote device with a temperature sensor is configured to track Supply, Return, or Outside Air Temperature and is connected to the thermostat, the current temperature readings will be displayed under Climate Control Group > (Thermostat) > Remote Devices.

    These temperatures are also currently and historically tracked over time, and are located on the Reference Graph within the thermostat’s History Graphs.

    Remote Proximity Sensor

    A Remote Proximity Sensor can be used to indicate when a door or window is opened or close, or it can be used as an external input dry-contact Occupancy Sensor that is used to determine whether a space is occupied or unoccupied.

    Within the Remote Device settings, the remote sensor can be toggled ON or OFF.

    Setting this to OFF will allow you to continue to monitor the state of the room without affecting the operation of the thermostat.

    Tip: When set to OFF, the Unoccupied Setback feature is no longer available for the master thermostat’s schedule.

    If the setting is ON operation will be as follows:

    • Door or Window: If a door or window is left open for one hour (default), an alarm notification will be generated. The HVAC system will shut off until the door or window is closed. The thermostat keypad will lock preventing manual setting changes. The LOCKED icon will blink indicating that the reason the thermostat is OFF is due to an open door/window.

      • When standard operation resumes, the thermostat will return to the settings prior to the door/window opening.

      Note: If you are monitoring more than one open door or window, the sensor type should be set to New Type, and the name should be specific, e.g., Room 101 Door Sensor. The reason for this is that if the word “door” is in the name, the Pelican system will recognize that the sensor is monitoring a door and it eliminates confusion when specifying the exact doors being monitored.
    • Occupancy: The system will either shut off, or it will automatically adjust the temperature setting based on the active occupied/unoccupied schedule setting for the thermostat. When standard operation resumes, the thermostat will return to the setting that is the currently active schedule.

    Remote Front Keypad

    If a Remote Wireless Thermostat is set to communicate with a master thermostat within a space, the front keypad can be LOCKED or UNLOCKED.
