 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-232 or 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.
