Cascade System Pump and

Sensor Wiring

1. On the boiler designated as the Master, connect

the system pump wiring to the terminal block at the

rear of the unit. Connect to terminals 10, 11, and

12 (See Fig. 19). The output is rated for pilot duty

only (2A maximum).

2. Connect the boiler pump wires to the terminal

block at the rear of their unit. Connect to terminals

4, 5, and 6 (See Fig. 19).

3. Connect the system supply sensor to terminals 3

and 4 on the J2 connector located on the Master

PIM (See Fig. 16).

4. Connect the Outdoor sensor (if used) to terminals

5 and 6 on the J2 connector located on the Master

PIM (See Fig. 16).

5. Connect the Enable/Disable wiring to terminals 9

and 10 on the J1 connector located on the Master

PIM (See Fig. 16). This connection must be pro-

vided through dry contacts closure.

NOTE: This dry contacts closure can come from a

room thermostat or a remote relay. No power of any

kind should be applied to either of these terminals.

Cascade Follower Pump

and Sensor Wiring

. Once the primary boiler has been identified, addi-

tional boilers will be designated as follower boilers.

nsure dip switch 2 on each follower VERSA is set

to the OFF/Down position (See Fig. 20)

2. For each follower boiler, connect the boiler pump

wires to the terminal block at the rear of each unit.

Connect to terminals 4, 5, and 6 as shown in Fig.

19.

3. The System and DHW pump outputs are not used

in the Cascade Follower configuration.
