R7184A,B,P,U Series 5

Interrupted Electronic Oil Primary,

EnviraCOM™ Enabled

APPLICATION

The R7184A,B,P,U Interrupted Electronic Oil Primary is a 
line voltage, safety rated, interrupted ignition oil primary 
control for residential oil fired burners used in boilers, 
forced air furnaces and water heaters. The 
R7184A,B,P,U used with a cad cell flame sensor, 
operates an oil burner and optional oil valve. 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 
UL296. 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.

The R7184 is EnviraCOM™ enabled, making it 
compatible with EnviraCOM™ home networks.

FEATURES

Thermostat(s)

The oil primaries are compatible with both standard 
thermostats and EnviraCOM™ communicating 
thermostats.

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 four 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 until the light 
emitting diode (LED) flashes (approximately 30 
seconds).

Data Port

Controls are designed to allow networking and upgrade 
modules to be added in the field by simply plugging them 
into the data port/network. (See Fig. 2.)

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.
