Introduction
The SRC-131 thermostat has been designed for use in hotel rooms, guest accommodation and locations where
the user will require a thermostat that is simple to understand and that functions in a logical manner. Further,
given the nature of the hospitality industry in general it is important that the thermostat be robust, flexible in
function and attractive. The SRC-131 thermostat has been designed with these important goals is mind.
The SRC-131 also offers advanced energy conservation features such as set point limit control, automatic
un-occupied heating and cooling settings as well as Modbus RTU communications for integration with the
“Building Automation System” (BAS) or “Hotel Check In” system. Additionally, the SRC-131 seamlessly
interfaces with the OC-3D occupancy detection system and HOT-242 “Door Station” system for added
functionality.
