Lockout Mode; Diagnostic Led; Specifications - Honeywell R7184A Series Quick Start Manual

R7184A,B,P,U SERIES 5 INTERRUPTED ELECTRONIC OIL PRIMARY, ENVIRACOM™ ENABLED
T-T Jumper
Select models have a pre-installed T-T jumper resistor.
To remove, use side-cutting pliers to cut the jumper. (See
Fig. 2.)

Lockout Mode

The R7184 will enter the lockout mode when:
• Flame is detected during valve-on delay.
• When flame is not established during Trial for Ignition.
• When flame is lost three times in one call for heat.
• When flame is detected during burner motor-off delay
period.

Diagnostic LED

The diagnostic LED has four states:
• On—Flame present.
• Off—No flame.
• Two seconds on, two seconds off—Recycle.
• 1/2 second on, 1/2 second off—Lockout.
Cad Cell Resistance
Cad cell resistance can be checked without using an
ohmmeter. During the run mode, press and release the
reset button. The resulting flashes indicate the
resistance. (See Table 3.)
Valve-on Delays/Blower Motor-off Delays
Select models may have fixed or selective delays for
valve open or blower motor off. The safety circuits will
check for flame during these delays and, if a flame is
present, will switch the control to lockout.

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 dual inline programmable (DIP)
switch positions 1 and 2. Select models have 0.5, 2, 4,
or eight minute delays. (See Fig. 2.)
69-1459—4
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).
Electrical Ratings:
Inputs:
Voltage: 102 to 132 Vac, 120 Vac nominal.
Current: 100 mA plus burner motor, valve and ignitor
loads.
Frequency: 60 Hz.
Outputs:
Relay Contacts:
Burner: 120 Vac, 10 full load amperes (FLA), 60
locked rotor amperes (LRA).
Valve: 120 Vac, 1A.
Ignitor: 120 Vac, 360 VA.
Alarm: 30 Vac, 2A.
Thermostat Current Available: 100 mA.
EnviraCOM™ Current Available: 150 mA.
NOTE: Reduce burner FLA rating by ignitor load. For
example, if the ignitor draws 3A (120 Vac, 360
VA), reduce the burner motor FLA to 7A.
