resideo R7284 Series Electronic Oil Primary User Guide
The following service procedures will help you become familiar with the R7284 electronic oil primary controls. For control operation, please refer to the basic control functions described on the back. For further information, wiring instructions and troubleshooting, please refer to the R7284 Installation Instructions, form number 69-2467.
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 ifdiagnostics 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.
Below is a typical progression of screens through a normal cycle.
Pressing up or down during the Ignition Trial enters pump prime.
Each press of the up button adds a minute, each press of the down button
subtracts a minute from the pump prime time.
If at any point there is an event generating a lockout, one of the following screens will be displayed.
Control is in Soft Lockout. Control will recover when error clears or after
specified time.
Control is in Hard Lockout. Hold “i” for at least 2 seconds to reset.
Hold the “i” button longer than 10 seconds to return to Standby
