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.

WHEN THE BLACK AND WHITE WIRES ON THE TRADELINE® R8182D
AQUASTAT® CONTROLLER ASSEMBLY ARE DISCONNECTED FROM
THE CIRCULATOR SWITCH AND ARE INTERCONNECTED, LOW LIMIT
AND CIRCULATOR CONTROL ARE BYPASSED. CIRCULATOR
OPERATES WITHY THEROMSTAT ONLY.
TO REPLACE R8182C,F, REMOVE BLUE WIRE AND INSULATE END.
DISCONNECT THE THE OTHER BLUE WIRE AT 4 AND WIRE TO
B
AT 3. WHEN CIRCULATOR IS CONNECTED BETWEEN ZC AND C2,
LOW LIMIT FUNCTION IS REMOVED AND CIRCULATOR OPERATES
WITH CIRCULATOR CONTROL (R TO W) ONLY.
CONTROL CASE MUST BE CONNECTED TO EARTH GROUND.
