Wireless (RF) Programmable Thermostat This programmable wireless RF controlled room thermostat set consists of a transmitter (TH-920D) and a receiver (RV-0356 - either Volt-free or Volt-output) with 30 meter range.
A unique facility called RF Address Code Setting is built into the RF receiver as part of the commissioning procedure. This ensures that the receiver will only respond to instructions sent to it from transmitter.
