The TR16 thermostat provides the latest technology in a full-featured universal thermostat with serial communications. The TR16 thermostat consists of two parts, a Wall Display Unit (WDU) and a HVAC Control Unit. The Wall Display Unit provides users functions like a traditional thermostat and connects to the Control Unit by a 4 wire cable. The Control Unit connects at the HVAC system using the standard thermostat connections and provides the thermostatic temperature control of the system. The Control Unit also has the serial RS485 communications network connection. The TR16 now maintains separate heating and cooling setpoints. The display shows the setpoint of the current operating mode (in Auto mode, the system keeps track of the current operating mode of the last call, either heating or cooling). New network commands have been added for a heating setpoint (SPH) and a cooling setpoint (SPC). Note that the TR16 maintains compatibility with single setpoint protocols by continuing to support the current SP command for both commands and status reports. In addition to the universal Standard or Heat Pump HVAC systems support, the TR16 has multistage heating/cooling system outputs. The control unit can support 2 stages of heating and cooling for Standard systems. It supports 3 stages of heating and 2 stages of cooling for Heat Pump systems. The TR16 has a convenient setup mode from the Wall Display Unit. You can set the network address, F or C display mode and easily calibrate the internal and all attached remote sensors. The TR16 has automatic detection and setup of remote temperature sensors. Remote sensors have address settings that, when detected by the TR16, will be used for specific functions, such as, in lieu of the internal sensor, averaging with other sensors. The TR16 can be used in a polled network such as the RCS CommStar network or can be set to AutoSend mode that will transmit changes in thermostat data as it occurs. Most operating parameters (variables), such as staging deltas, delays and run times are now viewable and adjustable from the network. Remote control of the TR16 via the serial communications network allows for the thermostat’s temperature, heating and cooling setpoints, operating mode and fan functions to be monitored or changed. A robust serial protocol allows full control of all the thermostat setup and operating parameters. Many new serial commands have been added to support the new features and to allow the operating parameters to be viewed or changed. |
