¶ 1.7.0
¶ New features
¶ Peripheral devices integration
The following peripheral devices have been integrated into the EMS:
- Fans:
- Weiguang (Modbus RTU)
- Generic radial fan (DIO)
- Air conditioning (AC):
- Envicool MC06-50 series
- Envicool MC90
- Fire Alarm Control Panel (FACP):
- Kentec SIGMA XT f
The devices can be added within the device manager in both Cloud and Local UI.
FANS
Once created, the fans are automatically controlled by the EMS based on the following temperatures:
- Indoor temperature: This can be taken from the inverters' reported cabinet temperature or a temperature and humidity sensor. This is mandatory, with the default set to the inverters' heat-sink temperature.
- Outdoor temperature: If available, it is provided by an air-conditioning system with an outdoor temperature sensor. This is optional; if not provided, the fan will be controlled only by the indoor temperature.
Note: the reference temperatures must be selected upon device creation (see below screenshot)
Control logic:
- The fan will turn on if the outdoor temperature exceeds 30°C (if outdoor temperature is available) or the indoor temperature reaches 70°C. Once started, it will run for 5 minutes.
- The fan will stop when the reference temperature drops 3°C below the threshold and the 5-minute running time has passed.
Notifications: Alerts are sent when the fan status changes or if the fan can't be controlled due to unavailable reference temperature data.
Please be aware that if a fan has been created and is linked to an Air-Conditioning and/or Temperature and Humidity sensor, the referenced devices cannot be deleted. The fan must be deleted first.
AC
The AC devices use default settings for operation, which cannot be changed in the EMS. The EMS controls the ACs based on these settings.
Alerts are sent when the AC device status changes, including error statuses and device alarms.
FACP
Notifications are sent via UI and mail when the FACP status changes, such as when it enters a fault state or a fire alarm is triggered.
¶ Changes
¶ Introduction of user-friendly notification when reports are not available
Previously, when the report service was unavailable, a technical error message was displayed in the UI. This has been replaced with a user-friendly message informing users that reports are currently unavailable.
¶
