SMART TEMP SMT-131 Hotel Touchscreen Thermostat User Manual

The Modbus data is provided in Addendum 1 at the back of this manual. (page 18).  
Modbus relies on a series connection and will normally not tolerate “Star” wiring or “T” branches.  
Remote Temperature sensors  
Occasionally the room thermostat cannot be installed in  
the ideal location to measure the room temperature  
accurately. In these circumstances the SMT-131 can use  
optional remote temperature sensors. These are a two-  
wire resistive device,(10K Type II NTC) not polarity  
dependent and simply wired into the SMT-131 sensor  
inputs terminals (“SI” and “Com 0-V”). Depending on  
installer menu sensor settings, (shown on page 17),  
remote sensor(s) will either override the SMT-131  
onboard sensor or average with the onboard sensor.  
Multiple sensors can be used for averaging over larger  
areas if necessary.  
Wireless (RF) remote sensors are also available if fixed  
wiring cannot be installed economically. (P/N RS-W).
