The RC2105 Series 2000 wireless heating system controller utilizes reliable Spread Spectrum Radio technology. Together with other existing Trs Systems WT2630A wireless space sensors and OST2630 wireless outside air temperature (OSA) sensors, the RC2105 controller will control the boiler system based on the average space temperature (up to 12 zones) and wireless outside air temperature. If the OSA temperature is below OSA set point and the average temperature is lower than the average space temperature set point, the heating system will be activated after a preset time delay (adjustable) by a relay output from the RC2105 controller to the boiler control system. The RC2105 provides maximum flexibility with extensive system adjustability, sensor selectability, alarms and reliable wireless sensor capability.

The RC2105 Series 2000 is also capable of communicating wirelessly with the Trs Systems RM9520 Receiver/Server. This enables the user to control and monitor their buildings remotely through the Local Area Network and/or the Internet.

The maximum radio transmission distance is dependent on building type. The maximum open-air transmission distance is one mile. In a typical commercial building with steel I-beam construction, concrete floors with reinforcing rod, and metal stud walls, it can be expected that transmissions will penetrate vertically through floors and horizontally through 200 to 500 feet of walls, furniture and air. Generally a wireless system will cover at least three floors - one floor above and one floor below the receiver location.
