Thermostat Network Control
The TU16 thermostat uses the UPB communications protocol, with extensions, to send and receive
network messages. For the complete UPB thermostat protocol, please refer to the RCS UPB Thermostat
Protocol Manual, document number 150-00205.
The TU16 has two UPB operation Modes, Link and Message. Link mode is a simple table of UPB Link
addresses mapped to thermostat modes or setpoints. Message Mode is a more robust protocol of
commands and messages designed for thermostats.
Link Mode Operation
UPB supports 250 Links with IDs from 1 to 250. The thermostat Link Mode uses Link ID’s from 200 to 210.
These Link IDs are mapped to the following thermostat modes or setpoints:
