The thermostat and base module contain selectable wireless
communication options. Each component has a jumper switch label
FSK and ASK. Default setting: FSK.
• All components must be set to the same position for wireless
communication.
• Both modes utilize a 916 MHz frequency.
• FSK: frequency-shift keying, is the recommended mode.
• ASK: amplitude-shift keying, should be selected when using
components that can not communicate with FSK.
