Communication Safety 
• In manual ON, thermostat and program modes of operation, the transmitter will send a 
communication safety transmission every 15-minutes.  This signal is further processed by 
the ignition control module to verify the transmitter is communicating properly. 
Room Temperature Limit 

• The Room Temperature Limit Shutdown feature will operate in MANUAL ON, 
THERMOSTAT ON mode, and PROGRAM ON modes. If the room temperature reaches 
95 deg. F or greater, the transmitter will automatically change to MANUAL OFF mode 
and send a MANUAL OFF command to the control module.  If the user turns the control 
back ON and the room temperature is still 95F or greater, the transmitter will switch to 
back manual OFF and send another OFF command the next time the transmitter reads & 
updates the room temperature (2-minute update interval).
