Protectorelay™ Primary Control
®
and Aquastat
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 highlimit 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.

OPERATION
R8182D wired for R8182B,E Replacement or R8182H wired for R8182J Replacement
When the R8182D or H is wired to exclude the low limit
circulator switches, the burner and circulator operate
whenever the thermostat calls for heat. On a call for
heat from the thermostat, 1K relay pulls in to start the
circulator. Then 1K2 closes and the 2K relay is
energized, which causes the burner to ignite by
closing the 2K1 contact. If the burner ignites and the
cad cell sees flame, the safety switch heater is
bypassed. When the thermostat is satisfied, the burner
and circulator are shut off.
With this hookup, the circulator operates whenever the
thermostat calls for heat (even if high limit is open).
R8182D wired for R8182C,F Replacement
When the R8182D is wired to exclude the low limit
function, the circulator is connected between the ZC
and C2 terminals. The burner operates on a call for
heat and the circulator operates whenever R-W is
made.

Zone Circulator Control with R8182D,H
The relay for each zone is connected to the Aquastat
Controller through terminals ZC and ZR. The R845
relay and thermostat for each zone can energize the
zone circulator through ZC only if R to W in the
Aquastat controller is made. If R to B (high-limit) is
made, the zone thermostat energizes the burner
through ZR.
Zone Valve Control with R8182D,H
The valve for each zone is connected to the Aquastat
controller by wiring end switches on the zone valve to
T-T on the R8182D,H. On a call for heat from any zone,
the R8182D,H operates the same as in a single zone
application.
STARTUP AND CHECKOUT
Explosion Hazard.
Can cause severe injury, death or equipment
damage.
Use this product only in systems with a pressure
relief valve.
Because heating systems differ, the correct
temperature setting for one system may not be correct
Fig. 9. R8182D and R845A in typical multiple
circulator zoning application.
R8182D,H (triple-function)
A call for heat by the thermostat pulls in 1K and 2K
relays to turn on the burner, and the safety switch
starts to heat. If the burner ignites within 45 seconds,
the cad cell sees the flame and the safety switch
heater is bypassed. The burner operates until the call
for heat is satisfied. The circulat or operates when relay
1K pulls in only if R to W in the Aquastat¨ controller is
made.
When R to B (low limit) is made by a drop in water
temperature, it acts as a call for heat, pulling in relay
2K to turn on the burner. Circulator cannot operate.
Multizone Control
In all multizone applications, a call for heat in any zone
energizes the safety switch circuit and relay 2K pulls
in. If burner ignites within the safety switch timing, the
cad cell sees the flame and the safety switch heater is
bypassed.
In all multizone applications, the low-limit control in
the Aquastat¨ controller acts independently to turn on
the main burner on a drop in water temperature. When
R to B (low- limit) is made, relay 2K pulls in to turn on
the main burner, the same as for single zone
applications.
69-0599—03 6
for another. Follow the boiler manufacture
recommendations for proper selection of settings. See
Fig. 11
High-Limit Setting
.
The high-limit opens and turns off the burner when
the water temperature reaches the setpoint. The highlimit automatically resets after the water temperature
drops past the setpoint and through the 10°F (6°C)
differential.
Set the indicator at the desired shutoff temperature.
Low-Limit /Circulator Setting
On a temperature rise, with the adjustable differential
at the minimum setting of 10°F (6°C), the burner
circuit
(R-B) breaks and the circulator circuit (R-W) makes at
the low- limit setpoint. See Fig. 11. On a temperature
drop of 10°F (6°C) below the setpoint, the R-B circuit
makes and the R-W circuit breaks.
At any differential setting greater than 10°F (6°C), the
R-B make temperature and R-W break temperature
remains the same—control setting minus 10°F (6°C).
The R-B break and R-W make temperature are the
setpoint temperature plus the difference between the
differential setting and 10°F (6°C).
EXAMPLE: Setpoint of 140°F (60°C), differential set at
25°F (14°C). On a temperature rise, R-B breaks and RW makes at 155°F (70°C). On a temperature fall, R-B
makes and R-W breaks at 130°F (54°C).

IMPORTANT
Once the setting stops are in place, they cannot be replaced. If they must be removed, cut
them off with cutters—do not twist off.
Part no. 126580 Setting Stops can be installed on the
low- and high-limit adjusting knobs to prevent turning
the knobs beyond a predetermined point. To install the
setting stops, proceed as follows:
1. On low-limit knob, turn knob to setting that is to
be established as the limit.
2. Place setting stop over knob so that arm of
setting stop (after stop is pressed into place)
strikes projection A and prevents turning of knob
beyond chosen limit setting (Fig. 11).
3. Press setting stop tightly onto knob so its inner
teeth securely engage knob.
4. Turn knob back and forth several times to make
sure stop functions properly.
5. Repeat steps 1 through 4 for high-limit knob.
After settings are made, replace the cover.
