Thermostat application Guide

The Bosch TSTBT4H2CP Thermostat Series consists of
4-wire MODBUS communicating thermostats. Utilizing
RS485 MODBUS protocol, the TSTBT4H2CP Thermostat
Series can communicate with the equipment, monitor the
performance, and report the status of the equipment.
The MODBUS protocol is received and then translated to
pulses to be received by the HVAC equipment. This
translation is performed by the TRM (Transmitting and
Receiving Module). The thermostat and TRM
communicate via 2 wire MODBUS, the TRM and the HVAC
equipment communicates via 4-12 wires utilizing pulses.
