Description

The mast-mounted LCD–1T Precipitation Sensor is engineered to operate with the Tekmar® 362 Mixing Control. It senses precipitation in any form throughout the temperature 0°F to 130°F (−18°C to 54°C)for improved snow melting system efficiency. The LCD–1T insures reliable operation independent of environmental conditions, in part, by regulating temperature of its moisture sensing grid.

The LCD–1T operates from a customer supplied 24 volt AC NEC Class 2 power source which is commonly available in hydronic systems. An isolated form A (SPST) relay contact that closes during precipitation interfaces with the Tekmar^® 362.

The LCD–1T mounts outdoors in elevated location that is freely exposed to rain and snow. It can be located up to 250' feet from the Tekmar^® 362 when using #18 extension wire. Longer distances are possible if a larger wire size is used. Contact Customer Service regarding the extension wire size required for longer distances.

High performance microcontroller technology eliminates the need for adjustments while providing reliable precipitation detection at a low cost. The LCD–1T does not require preventative maintenance. Based upon field experience, the mean time to failure of the LCD product family exceeds 1.2 million hours or approximately 15 years.
