To provide remote control communication equipment of a gas burning appliance which is superior in noise resistance and redundancy and high reliability.

This equipment is provided with a microprocessor 3 which executes a prescribed communication protocol, a signal detection circuit 4 which modulates and demodulates transmission data and a carrier frequency decision circuit 5 which sets a detection carrier frequency fc, and in the remote control communication equipment, which superposes the transmission data on the carrier Cr and transmits it in a gas burning appliance, the microprocessor 3 varies the frequency of the carrier Cr, in response to the situation of a transmission line 6 and transmits data in carrier frequency which has no faults in data transmission.
