R8182J
The burner and circulator operate whenever the thermostat 
calls for heat. Relay 2K pulls in. When the cadmium sulfide 
flame detector sees flame, the safety switch heater circuit is 
bypassed, and 2K is held in through 2K1. If temperature rises 
to a high limit setpoint, R to B breaks, shutting off the burner. 
The circulator continues operation under direction of the 
thermostat. See Fig. 15, 16, 17 and 19.
Multizone Control
In all multizone applications, a call for heat in any zone 
energizes the safety switch circuit and relay 2K pulls in. If the 
burner ignites within the safety switch timing, the cadmium 
sulfide flame detector sees flame and the safety switch heater 
is bypassed.
In all multizone applications with R8182D and H, the low limit 
control in the Aquastat® limit 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 application.
Zone Circulator Control with R8182D,H
The relay for each zone is connected to the Aquastat® limit 
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® limit is made. If 
R to B (high limit) is made, the zone thermostat energizes the 
burner through ZR.
Zone Circulator Control with R8182E,J
The relay for each zone is connected to the Aquastat® limit 
through terminals ZC and ZR. The R845A Relay and 
thermostat in each zone can energize the zone circulator 
through ZC on a call for heat. If R to B (high limit) is made, the 
zone thermostat energizes the burner through ZR.
Zone Valve Control with R8182
The valve for each zone is connected to the Aquastat® limit 
by wiring end switches on the zone valve to T-T on the R8182. 
On a call for heat from any zone, the R8182 operates the 
same as for single zone applications.
