Multiple Zone Pump Controller

Models Taco SR504, Argo ARM 861 Series

Figure 32 shows the basic multiple zoned system using circulating pumps. This wiring system is used with the piping as shown in Figures 25.

When there is a call for heat the room thermostat closes the circuit between the TT terminals on the pump controller. The controller energizes the appropriate circulating pump and closes the circuit between terminals T and C on the Sentry 2100 control. The Sentry 2100, provides power to the primary pump via terminal C1. Once these pumps are on, the burner ﬁres.

Once the room thermostat is satisﬁ ed, it breaks power to the TT terminal of the pump controller de-energizing the XX contacts. The circuit between terminals T and C opens shutting down the pumps and the burner.
