P. CASCADE FOLLOWER PUMP AND SENSOR WIRING
1. If it is desired to have the boiler control the boiler pump, connect the boiler pump to the BOILER HOT,
BOILER NEUT, and BOILER GND terminals.
2. If you are using an indirect fired water tank connected directly to the follower boiler, connect the pump
for it to the DHW HOT, DHW NEUT, and DHW GND terminals.
If desired, an alarm bell or light can be connected to the alarm contacts of the follower boiler. The
normally closed alarm contact may be used to turn a device off if the boiler goes into lockout mode. The
alarm contacts are rated 5 amps at 120 VAC.
To connect an alarm device, connect the power for the device to the ALARM COM terminal. Connect the
alarm device hot wire to the ALARM NO terminal. Connect the neutral or return of the alarm device to the
neutral or return of the power for the alarm device.
