TEKMAR 1873 Ice and Snow Detection Thermostat

A modular device designed for ice and snow detection, the TEKMAR 1873 thermostat offers great flexibility for expansion and integration. Operating autonomously, it can also serve as the base for a multi-channel system connected to building management or the tekmar Connect server.

Scalable Configuration

In standard configuration, the system includes a combined sensor and a heating circuit. Adding an Internet or Modbus gateway enables remote control, monitoring, and maintenance via building management platforms or dedicated user portals.

Multi-Channel Capabilities

The installation can evolve into a multi-channel system using the 1875 expansion module, accommodating up to eight sensors and heating circuits. Each circuit is assigned to one of four available zones, each benefiting from specific preheating and heating settings, weekly schedules, as well as a separate holiday program.

Technical Specifications

  • Simultaneous management of one sensor and one heating output
  • Continuous temperature measurement in the heated zone
  • Humidity measurement triggered below critical temperature
  • Minimum heating cycle startup following high humidity detection or via external signal
  • Complete monitoring of all ice and snow detectors and their sensors
