Modbus/RTU thermostat touchscreen with I/O


Product code: SMT131

The SMT-131 offers a big bright display that provides feedback of the air conditioning status and permits the guest to easily turn the air conditioning on/off and adjust temperature/fan control. If the optional occupancy module is fitted, the SMT-131 will automatically change to a low energy consumption mode when the room is vacant. The optional outside door station module further adds to the capability of the SMT-131 by providing the guest with the ability to call for housekeeping or request that they are not disturbed.


The SMT-131 provides a total solution for air conditioning control and by adding optional logic modules, extends the SMT-131 capabilities.
