B) Digital Temperature Sensor:
Senses return temperature and is required for manager to work properly. 100°F light flashes if sensor is not
working properly. Disconnect RED lead to run in the "Service Board Mode".
C) Monitor Contacts:
For connection to System Monitor or security systems are located here.
D) Option Switches:

E) Temperature Display:
Indicates boiler RETURN temperature, not supply temperature.

The Manager is the operating aquastat and will turn off the burner if return temperature reaches 170°F
(operating limit).

The zone outputs will open when the return temperature is above 140° F and close zone outputs when the
return temperature drops below 120° F. If a new zone calls when the returns are below 140° F the new zone
will not open until the temperature exceeds 140° F (even if other zones are open).

The boiler will typically take about 2 minutes to reach 140° F from a cold start.
When the Manager is working properly and has found a condition that needs service, the 100º, 120º,
130º, or 140º light will flash (See Trouble Shooting with the Digital Manager, Page 17).

circulator relay, providing 120-volt power to both the bypass circulator and the burner.
