R8182D,H Combination
Protectorelay™ Primary Control
and Aquastat
®
Controller
APPLICATION
The R8182D,H Controllers combine a Protectorelay™
Primary Control and an Aquastat® Controller for use
in oil-fired, hydronic heating systems. The Aquastat
Controller provides high and low limit protection,
circulator control, and minimum water temperature
control for tankless domestic hot water service.
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 auxiliary ZC and ZR terminals provide zone
control through an R845A Switching Relay. Each
additional zone requires a separate 24V thermostat
and an R845A Relay.
The R8182D,H also provide zone control using zone
valves. Each additional zone requires a separate 24V
thermostat and a V8043 or V8044 Zone Valve. The
R8182D,H can be converted to provide only the high-
limit to replace an R8182B,E or only the limit and
circulator function to replace of the R8182C,F.
The R8182D mounts directly on the boiler. The
R8182H mounts on a 4 by 4 in. junction box and has a
5 ft. (1.5m) capillary that allows a remote sensor
location.
The R8182D includes
• Bag of heat-conductive compound for better heat
transfer.
• High- and low-limit setting stops.
• One wire nut.
To order an immersion well or a well adapter, see form
68-0440, Wells and Fittings for Temperature
Controllers, for part numbers and descriptions.
INSTALLATION
WARNING
Explosion Hazard.
Can cause severe injury, death or property
damage.
Use this product only in systems with a
pressure relief valve.
When Installing this Product…
1.
Read these instructions carefully. Failure to fol-
low them could damage product or cause a haz-
ardous condition.
2.
Check the ratings given in these instructions
and on the product to be sure product is suit-

WARNING
Electrical Shock Hazard and Explosion
Hazard.
Can cause severe injury, death or equipment
damage.
1. Disconnect the power supply before
beginning installation to prevent electrical
shock or equipment damage.
2. Be sure that 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. If the sensing bulb does not
fit snugly inside the immersion well, use the
heat-conductive compound as described
below. See Fig. 3.
Mounting the R8182D
See Fig. 1 for R8182D installation dimensions and
Fig. 4 for an internal view of the R8182D.
If existing immersion well does not fit the R8182D
immersion well clamp, use a 124904 Immersion Well
Adapter, ordered separately from form 68-0040.
1.
Disconnect power supply.
2.
Drain all water from boiler.
3.
Fasten R8182D immersion well clamp to flange
on immersion well adapter. See Fig. 3.
4.
Place adapter on capillary tube.
5.
Put adapter end into hole in controller case and
tighten clamp screw.
