TM-1873 / 1875
Ice and Snow Detector
The base device 1873 can be used as an individual unit or as a foundation for constructing an ice detection system with multiple channels and communication with building management systems or
the tekmar Connect server.
A single-channel system consists of a base device with a combined sensor and a heating circuit. It can be extended with an Internet or Modbus gateway, allowing remote control, monitoring, and maintenance via the building management center or the platform independent user portal of the tekmar Connect server.
The 73 system can be expanded, if necessary, with the extension device 1875 to become a multi-channel system with up to eight sensors and heating circuits. The heating circuits can be assigned to up to four different zones, each with a separate preheating and base heating mode, as well as distinct weekly schedule programs and a holiday program. The sensors in a zone can be linked to a signaling circuit, where one of the sensors activates all the heating circuits of the channels belonging to the zone.
FEATURES
- Control and monitoring of a sensor and a heating output
- Continuous temperature monitoring in the heated area.
- Activation of humidity measurement when the temperature drops below the activation temperature.
- Start of the minimum heating time when the humidity threshold on the sensor is exceeded, or alternatively by an external signal at the control input.
- Monitoring of all ice and snow detectors and their sensors in an installation.
