operation, please refer to the basic control functions described on
the back. For further information, wiring instructions and

Pump Priming Cycle
To facilitate purging air from the oil lines and filters, the R7284 can
be placed in a purge routine by pressing and releasing the up
arrow button during the Trial For Ignition.
In the advanced interface “PUMP PRIME” is displayed on the
display along with the time left on the Trial for Ignition (TFI).
Pressing the up arrow button adds a minute to the TFI time for a
maximum of 10 additional minutes (press the up arrow button 10
times). Pressing the down arrow button subtracts a minute from
the TFI time.
There is no visual indication for the basic interface control and the
purge timing is limited to five minutes.
Home Screens (Advanced Interface)
Pressing the “i” button longer than 2 seconds in states other than
Standby Interrupts control operation.
Once the held key is released a 3 second count down begins to
restart the cycle if the call for heat is still present.
• Holding all 3 buttons longer than 2 seconds in any state puts
the display in the Installer Setup (ISU) mode.
• Pressing “i” in any state enters the Diagnostic screen if
diagnostics are enabled outside of the Installer Setup mode.
• Pressing up or down in any screen enters Error History if
diagnostics are enabled outside of the Installer Setup mode.
