The RTS is a wake-up device so to speak. As it is battery operated it does not communicate as often as other Z-Wave devices as a means to conserve battery life. Additionally, the RTS does not respond to polling, the device is designed to send a signal when the temperature shifts a full degree one way or the other. This is something that cannot be changed.
How long does the does the system take to shut off after the RTS reports a change?
