Timing
Valve-on Delay: 0 or 15 seconds.
Blower-off Delay: 0, 2, 4, or 6 minutes, field-selectable using
DIP switch positions 1 and 2.
NOTE: For universal R7184U model, valve-on delay and
blower-off delay timings can be enabled or disabled
(values are zero) in the field using DIP switch
position 3. See installation instructions, form 69-1233.
Electrical Ratings:
Inputs:
Voltage: 102 to 132 Vac, 120 Vac nominal.
Current: 50 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).
NOTE: Reduce burner motor FLA by ignitor load. For
example, the ignitor listed below draws a maximum
of 3A (120 Vac, 360 VA). Reduce the burner motor
FLA to 7A.
Valve: 120 Vac, 1A.
Ignitor: 120 Vac, 360 VA.
Alarm: 30 Vac, 2A.
Thermostat Current Available: 100 mA.
Environmental Ratings:
Operating Ambient Temperature:
-40°F (-40°C) to +150°F (+66°C).
Shipping Temperature: -20°F (-29°C) to +150°F (+66°C).
Humidity: 90% relative humidity at 95°F (35°C) noncondensing.

OPERATION
The R7184 is a microprocessor-based control. The LED offers
diagnostic information for lockout, recycling and patented cad
cell status. There is a manual reset button to exit the lockout
state and enter the idle state.
TYPICAL CONNECTIONS
Fig. 1 through 4 show typical R7184 connections.
NOTE: When installing the R7184 with a line voltage
thermostat, connect the line voltage thermostat in
series with the limit controller.
