Serial RS-485 Thermostats

TR16	TR40
Separate Heat and Cool Setpoints Up to 3 Stage Heat, 2 Stage Cool Remote control of all functions via RS-485 remote interfaces Two part design Backlit LCD Wall Display Unit For standard gas/electric or heat pump HVAC systems Replaces existing 4 or more wire thermostats without the need for additional wiring Optional Remote Temperature Sensor

The TR16, or TR40,  connects to, monitors and controls an HVAC mechanical system via it's standard thermostat connections. The TR16, or TR40, consists of two components, the Wall Display Unit (WDU) and the Thermostat Control Unit (TCU).  Normal local control of the HVAC system is provided by the  WDU with its typical thermostat like user interface. The TCU provides all HVAC mechanical systems outputs as well as the  RS-485 remote systems interface.

The  WDU and TCU connect to each other,  via a 4-wire RCSLink (2 power, 2 data) using the existing thermostat wiring. The TCU connects to an automation system via cat-5 wiring.
