The text and paths in this guide follow the current app.voltic.es interface. The app version, user role, and building configuration can change what appears. The screenshot inventory lists pending captures and the details that must be confirmed before definitive values are published.
Screens involved
Configure alerts and thresholds
Configure one sensor
1
Open the configuration
In the building view, open the CoolingPatrol Alerts tab. Check each sensor’s name and location before editing it.
2
Define the range
Turn on Alert enabled and define Minimum and Maximum. The range must come from the product preservation plan and the site’s procedure, not from a generic recommendation.
3
Review advanced settings
If available, open Advanced alert settings:
- Hysteresis: margin the system applies around a limit; confirm with the technical team how it affects alerts.
- Cooldown: minimum time between consecutive notifications.
- Breach duration: time the reading must remain out of range before creating a deviation.
4
Save and check
Save the configuration and return to Cooling Patrol > Overview. Check that the range appears beside the sensor and that its status is not Not configured. Record who approved the range and when it changed.
Apply one configuration to several sensors
In CoolingPatrol Alerts, select the sensors and use the bulk configuration. The app warns that the complete configuration will be applied to every selected sensor and replace its previous settings. Check locations before confirming: a chilled-food room and a freezer will normally use different ranges.Do not publish default values, maximum numeric limits, notification channels, or escalation rules until the technical team confirms them. The screen shows the fields, but the correct value depends on the product and service contract.
Daily operation
At the start of a shift
- Open Cooling Patrol > Overview and select the relevant period.
- Check the overall indicator, the number of Online and Offline rooms, and Active alerts.
- Review Critical rooms first, then Warnings, Close to limit, and No data.
- Open the details of any sensor with an old reading, low battery, or incorrect location.
- If the Cooling Patrol Hub is offline, start the connectivity-loss procedure before accepting the overview as current.
During the shift
- Check new alerts and assign a responsible person to each one.
- Do not close an alert just because a reading briefly returns to range: verify the cause and record it.
- Avoid opening the room longer than necessary and do not move the sensor during an investigation.
- If the sensor has no data, take a manual measurement and record the time, instrument, and result.
At the end of a shift
- Confirm that every alert has an owner and no HACCP incident is still undocumented.
- Export the period if the site’s procedure requires it.
- Record threshold changes, battery replacements, network incidents, and corrective actions in the maintenance log.
States shown by the app
History, trends, and export
Review one sensor’s history
From Cooling Patrol > Overview, select a room and open Sensor details. The screen shows the current reading, allowed range, status, battery percentage and voltage, last update, and a Temperature history chart. In the interface observed, the sensor chart represents the last 24 hours with 15-minute averages and marks the configured limits. Confirm this interval before turning it into a control or audit requirement.Review a period
In Overview, switch between Daily, Weekly, and Monthly, and adjust the From and To dates. When enough data is available, the panel calculates:- average temperature for the period;
- compliance, meaning time within range;
- online/offline room count;
- active alerts split into critical and warning;
- average trend and recent alerts.
HACCP register and reports
The HACCP area has three tabs:- Register: filter All, Open, Resolved, or Reviewed, by date, and search by sensor or location. The table shows start, excursion, duration, and status.
- Alerts: review each sensor’s range and state and open its advanced configuration.
- Reports: choose a Daily, Weekly, or Monthly period, select the date, and enable Include charts per sensor when needed.
Connectivity loss
If the Cooling Patrol Hub is offline
The app shows a warning that the gateway/Hub is not responding and that the data shown is the last reading received. Follow this order:- Check the USB-C power supply and make sure the Hub has not been moved or unplugged.
- Check the Ethernet cable and network port; if it uses Wi-Fi, verify that the network and password are still available.
- Check whether other devices in the same building are connected.
- Do not treat old readings as current. Take manual measurements in the affected rooms.
- When the connection returns, wait for Last update to refresh and confirm that each sensor returns to Online.
- If it does not recover, record the start and end time, Hub serial number, and manual measurements, then contact support.
If only one sensor shows no data
- Open its details and check Last update, battery, and signal data.
- Check that the sensor is still in the labelled location and has not been covered, wet, or damaged.
- Check the battery using the model manual; do not swap cells or open the enclosure unless the procedure allows it.
- If the other sensors work, do not change thresholds to hide the issue.
Batteries and maintenance
Sensor details show battery percentage and, when sent by the device, battery voltage. Use both values to plan maintenance, but do not turn a percentage into a replacement date without the manufacturer’s table.Recommended routine
- Check percentage, voltage, and last-update date weekly.
- Inspect the enclosure, screws, cable glands, and seals without removing protection unnecessarily.
- Clean the outside with a dry cloth; do not spray liquid on the sensor.
- Check for condensation, ice, corrosion, or impact damage.
- Record date, sensor, location, readings before/after, removed cell, installed cell, and responsible person.
- After any intervention, confirm a stable reading and the correct alert state in the app.
The sensor type, capacity, expected life, polarity, replacement procedure, and protection rating are not defined in this documentation. They must come from the technical manual for the installed model.
Calibration and placement
Place the sensor
Install the sensor at a representative point for the stored product and leave room for air circulation. Avoid:- direct airflow from the evaporator or fan;
- immediate proximity to the door, seals, or warm-air inlets;
- direct contact with walls, ceiling, floor, trays, or product;
- areas where it can be hit, wetted, iced over, or covered;
- moving it to another room without updating its name and location in the app.
Check a reading
- Use an identified reference thermometer with current calibration.
- Place it beside the measurement point without blocking the sensor.
- Compare several stable readings and record date, time, instruments, temperature, difference, and responsible person.
- If the difference exceeds the procedure’s tolerance, keep the record, mark the sensor for review, and contact support.
- Do not enter a manual offset in the app unless the technical team confirms that the model and version support it.
Sensor troubleshooting
Critical-alert procedure
1
Confirm the alert without delaying the response
Open the sensor and record the reading, limit, time, and duration shown. If it shows No data or Offline, treat it as a monitoring loss and take a manual measurement.
2
Protect and verify the product
Keep the door closed, limit openings, and check the room with a reference instrument. Follow the HACCP plan and the food-safety responsible person’s instructions to hold, move, or release product.
3
Find the cause and escalate
Check refrigeration equipment power, door and seals, evaporator, condensation, load, and connectivity. Notify the shift lead and maintenance. Do not change the threshold to make the alert disappear.
4
Document the deviation
In HACCP > Register, open the incident and complete at least Cause, Corrective action, and, when applicable, Affected product, Lot, Quantity, Product disposition, and Responsible. Use Save without resolving if the investigation is still open.
5
Resolve and review
Resolve only after the room has returned to range and the corrective action has been checked. An authorised reviewer can use Review and lock; a reviewed incident is locked against later changes.
Preservation and traceability when applicable
If the site follows a HACCP or equivalent procedure, preserve at least the evidence required by that procedure:- the report PDF and, when used, CSV/XLS export of the register;
- covered period and building time zone;
- sensor, location, serial number, and current range;
- start, recovery, duration, limit, initial, peak, and final temperature for each deviation;
- cause, corrective action, product/lot/quantity, disposition, and responsible person;
- manual measurements and calibration checks;
- battery changes, maintenance, and connectivity loss;
- who resolved and who reviewed/locked the incident.
