Honeywell R8182D, R8182E, R8182F, R8182H, R8182J User Manual
R8182D,E,F,H,J Combination
Protectorelay™ Primary Control and
APPLICATION
The R8182 combines a Protectorelay™ primary control
and immersion type Aquastat® controller in one unit for
use in oil-fired, hydronic heating systems.
The Protectorelay™ primary control provides control of a
line voltage, intermittent ignition oil burner when used
with a C554A Cadmium Sulfide Flame Detector and a
24V thermostat.
The R8182 models provide switching as follows:
Model Switching
R8182D High limit, spst;
R8182E High limit, spst
R8182F High limit, spst
R8182H (with remote bulb) High limit, spst
R8182J (with remote bulb) High limit, spst
The auxiliary ZC and ZR terminals on the R8182D,E,H,J
provide zone control through an R845A Switching Relay.
All models are capable of zone control using zone
valves. Each additional zone requires a separate 24V
thermostat and a V8043 or V8044 Zone Valve.
The R8182D,E,F models mount directly on the boiler.
The R8182H,J models mount directly on a 4 by 4 inch
junction box and have a 5 foot (1.5 meter) armored
capillary for remote sensor location.
To order an immersion well, use form 68-0040
Fittings for Temperature Controllers
and descriptions.
Refer to Fig. 1 through 3 for installation dimensions.

CAUTION
1. Disconnect the power supply before
beginning installation to prevent electrical
shock or equipment damage.
2. Be sure that the combustion chamber is
clear of oil or oil vapor before starting burner.
3. Be sure that the ambient temperature at the
element does not exceed 250°F (121°C).
IMPORTANT
Be sure that the sensing bulb fits snugly inside
the immersion well and that the sensing bulb
rests against the bottom of the immersion well.
Refer to Fig. 3.
Mounting the R8182
Disconnect power supply.
Drain all water from boiler.
Most boilers are equipped with a tapping that
allows horizontal mounting of immersion well
where average temperature boiler water circulates
freely. If no tapping is provided, prepare one.
Install immersion well or compression fitting
(ordered separately) by threading immersion well
into tapped hole.
For R8182D,E,F models:
a. Loosen immersion well clamp screw on side
of R8182 case.
b. Insert bulb into immersion well until it bottoms.
c. If necessary, bend capillary tube to hold
bulb against bottom of immersion well.
NOTE: Do not make sharp bends in the tubing.
A sharp bend can break the tubing and
cause a loss of fill. In models with an
adjustable tubing length, pull the extra
tubing out of the controller case.
d. Fit controller case onto immersion well so
that immersion well clamp slides over flange
of immersion well.
e. Securely tighten immersion well clamp screw.
For R8182H,J models:
a. Loosen the screw holding the hinged
backplate to the controller case and swing
the backplate away from the controller case.
b. Screw the backplate to a 4 by 4 inch
junction box.
c. Insert bulb into immersion well until it bottoms.
d. If necessary, bend capillary tube to hold
bulb against bottom of immersion well.
NOTE: Do not make sharp bends in the tubing.
A sharp bend can break the tubing and
cause a loss of fill. In models with an
adjustable tubing length, pull the extra
tubing out of the controller case.
e. Tighten immersion well screw over brass
collar.
f. After wiring, swing the control against the
backplate and refasten the screw.
Refill the boiler and check for water leakage.
