R7184U Key Features Diagnostic LED Indicator light monitors burner flame status and system lockout The versatile R7184U includes these “Exclusive Features”: Pump priming cycle Cad cell flame strength indicator Limited recycle Extended Service Life (Control and Application)

Additional R7184U Features Available in 15-, 30-, and 45-second lockout times R7184U1004 = 15 second lockout R7184U1012 = 30 second lockout R7184U1020 = 45 second lockout Optional valve-on delay, blower-off delay models: Models: 15 seconds, or selectable 0 or 15 second valve-on delay Zero time or selectable 0-, 2-, 4-, 6-minute blower-off delay Safe start check – check for flame presence prior to lighting the burner Compatible with power venters without integral timers Oil-resistant plastic cover for electronics

R7184U Feature Function Benefit Pump Purge Temporary setting of safety timing to 4 minutes Allows installer to purge oil lines without remaining at oil primary CAD Cell Resistance Readout Flash CAD resistance range while burner is running Allows installer to check that flame strength is adequate prior to leaving job site Limited Recycle Limits recycle to 3 per any one call for heat Detects running saturation or poor combustion from partially clogged nozzle and locks out to prevent heat exchanger clogging or oil flooding Limited Reset Limits resets to 3 during any single call for heat Prevents homeowner from continually pressing reset button when service is needed Communications HVAC communications Allows local and remote diagnostics for better troubleshooting and new services

R7184U Feature Function Benefit Communicating Accessories Additional devices to utilize communications capability Remote access, test tools Leadwire and Quick Connect Termination Support both quick connects and leadwire termination Replaces both OEM and installed base with one model Alarm Contacts Indication of control lockout Allows connection to security system or other indications to warn of control lockout Selectable Valve On Delays Field selectable valve on delay Allows user to inventory and carry one universal product for various valve on delay times Selectable Blower Off Delay Field selectable blower off delay Allows user to inventory and carry one universal product for various blower delay on times

Key Features: Oil Primary R7184U EnviraCOM™ Communications Data Port Diagnostic LED – enables monitoring of system status to speed troubleshooting Limited reset – prevents continued homeowner reset without proper service checkout EnviraCOM™ Terminals. Alarm Contacts (dry contacts, normally open) – Provides switch action to remote alarm panels T-T Terminals Timer Setting Dip Switches – Universal Application

Installation

Installing the R7184U Follow the installation instructions per the application: Locate proper location Mount Wire per application type Oil fired boiler without EnviraCOMTM Oil fired boiler with EnviraCOMTM Oil fired forced air with EnviraCOMTM Etc.

Troubleshooting

Troubleshooting of the R7184U The indicator light on the control provides lockout, recycle and cad cell indications as follows: Flashing at 1 Hz (1/2 second on, 1/2 second off): system is locked out or in restricted mode. Flashing at 1/4 Hz (2 seconds on, 2 seconds off): control is in recycle mode. On: cad cell is sensing flame. Off: cad cell is not sensing flame. Cad Cell Resistance Check For proper operation it is important that the cad cell resistance is below 1600 ohms. During a normal call for heat, once the control has entered the Run mode, press and release the reset button. Indicator light will flash 1 to 4 flashes. See next slide for equivalent cad cell resistance.

Troubleshooting: Diagnostics Push lockout button once to get cad cell resistance and system status Flashes Indication Steady Control is sensing flame Off Control is not sensing flame Flashing ( ½ sec on / ½ sec off) Control is in lockout or restricted mode Flashing ( 2 sec on / 2 Sec off) Control is in recycle mode 1 < 400 ohms 2 400 - 800 ohms 3 800 - 1600 ohms 4 1600 – 5000 ohms *CAD Cell Ohms decreases with increased flame brightness
