Connect alarm directly to Q7800 terminal 3. d On power burners, identify burner motor wire on terminal 3 and connect it to Q7800 terminal 4. e Select amplifier to match detector being used. f On UVM models, the detector must be changed to a Honeywell C7027 or C7035. REPLACEMENT DIRECTIONS: 1. Disconnect all power to programmer. 2. Remove old programmer from subbase (trade-in to Honeywell Authorized Flame Safeguard Distributor). 3. Mark all wires on subbase; i.e., wires connected to terminal “1” should be marked “1.” Disconnect wires as they are marked. 4. Remove old subbase. 5. Mount Q7800A Subbase. 6. Connect wires to subbase per attached cross reference. Pay close attention to footnotes. For example: to convert a Fireye UVM-2 to a RM7895, the wire marked “A” would connect to terminal #9 on the Q7800. The wire marked “8” would connect to Q7800 terminal #8. 7. A superscript letter, such as “a” designates a footnote. Study these footnotes carefully. 8. Plug in the RM7895. Make sure you select the proper ST7800A Purge Timer and Detector for the application. 9. There are 2 wires on the amplifier section of the RM7895, which are used to select the desired trial for ignition timing and mode (lock-out or recycle). Refer to the RM7895 instruction sheet (form 66-1090) for assistance with proper selection. 10. If a low voltage controller is used on the RA890 or UVM-1, remove it and replace it with a line voltage controller. The line voltage controller should be connected in series with the limits. 11. If a low voltage airflow switch is used on the RM7895, it must be replaced with a line voltage airflow switch. 12. The following models are recommended for replacements: 70-8911 19
