The primary controls fuel oil, senses flame, controls ignition spark and notifies a remote alarm circuit when in lockout. The R7184 can be used with both hydronic and forced air systems. When used with hydronic systems, line voltage switching Aquastat® Controllers normally provide for the starting and stopping of the combustion sequences. With forced air systems, both mechanical and electronic low voltage thermostats control the starting and stopping of the combustion process. Some hydronic and forced air systems now require a delayed valve-on and burner motor-off delay. The R7184 operates an oil valve that prevents the flow of oil when the burner motor is running prior to combustion (delayed valve-on) and when the burner motor is running after combustion (burner motor-off delay). The R7184 models are intended for use only on oil burning appliances which do not require prepurge and post-purge as a safety related function as defined in UL 296. The valve-on delay and burner motor-off delay in this control are intended only to help establish draft and reduce oil after-drip related problems. FEATURES Limited Recycle This feature limits the number of recycle trials (for each call for heat) to a maximum of three trials. If the flame is lost three times and does not successfully satisfy a call for heat, the R7184 locks out. Pump Priming Cycle To facilitate purging air from the oil lines and filters, the R7184 can be placed in a purge routine by pressing and releasing the reset button during the safety check, delayed valve-on , ignition or carry-over periods. The lockout timing will be extended to 4 minutes and the ignition set in the intermittent mode for this cycle only. The R7184 automatically reverts to its labeled interrupted and safety switch timing states. The pump priming cycle can only be entered if there have been no lockout occurrences since the last successful heat call. To reset the device so that the pump priming cycle can be entered, press and hold the reset button for 30 seconds until the LED flashes twice. Disable Function Pressing and holding the reset button will disable all functions until the button is released. The R7184 will restart at the beginning of the normal heat cycle on safety check. Limited Reset (Restricted Mode) In order to limit the accumulation of unburned oil in the combustion area, the control can only be reset three times. The reset count returns to zero each time a call for heat is successfully completed. To reset from restricted mode: Press and hold the reset button for 30 seconds. When the LED flashes twice, the device has reset. SPECIFICATIONS Models: Table 1 lists the major features and the applicable wiring diagram numbers for the R7184. Timing: Safe Start Check: 5 seconds (approximately). Valve-on Delay: 15 seconds. Burner motor-off Delay: 0, 2, 4, or 6 minutes, field- selectable using DIP switch positions 1 and 2. NOTE: For universal R7184U model, valve-on delay and burner motor-off delay timings can be enabled (values as listed) or disabled (values are zero) in the field using DIP switch position 3. Lockout: 15, 30 or 45 seconds (factory-programmed). Recycle: 60 seconds (fixed). Ignition Carryover: 10 seconds (fixed). ® U.S. Registered Trademark Copyright © 2000 Honeywell Inc. • All Rights Reserved 69-1233-2 R7184A,B,P,U INTERRUPTED ELECTRONIC OIL PRIMARY R7184A,B,P,U INTERRUPTED ELECTRONIC OIL PRIMARY : NOTE: Reduce burner FLA rating by Ignitor load.
