NEW! Now with dual Setpoints (separate Heat and Cool) and Multi-Stage Outputs.
The TR40 connects to, monitors and controls an HVAC mechanical system via it's standard thermostat connections. The 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.
