9.23 T-Stat
The T-Stat communicates with the Supervisory Controller
using the MODBUS network. The thermostat enables the
controller to read status information from the device as well
as send operational setpoints to the device. The device
communicates using 8 data bits and 1 stop bit. For the full
thermostat user manual, refer to P/N 026-1729.
This thermostat replaces thermostats for the following types
of system:
• Standard Heat and Cool Systems
• Two Stage Heat and Two Stage Cool Systems
• Air Source Heat Pump (with Aux. or Emergency Heat)
• Ground Source Heat Pump (with Aux. or Emergency
Heat)
• Air or Ground Source Heat Pump (No Aux. or Emergency
Heat)
• Standard Heat Only Systems
• Standard Central Air Conditioning
• Gas or Oil Heat
• Electric Furnace
• All Systems Listed Above with Economizer Control
9.23.1 General Control
• The Supervisory Controller communicates with the
device via Modbus. The thermostat communicates using
8 data bits, and 1 stop bit. Baud rate and parity can be
changed on the device using dip switches.
• The Supervisory Controller will just provide an interface
to the devices. The White Rodgers Thermostat monitors
all information.
9.23.2 Alarms

9.24 Touch T-Stat
The Programmable Touchscreen Thermostat is a
configurable device intended for light commercial
applications. The thermostat is a communicating, intelligent
sensor and controller combination with built-in temperature
and humidity sensors used to control systems such as
conventional Rooftop Units (RTU) and Heat Pumps (HP). The
thermostat communicates over a Modbus RTU network that
easily integrates with a building management system (BMS).
For the full user manual, refer to P/N 026-1739.
