A. Zoning with CIRCULATORS, suggested applications

Threespaceheatingzones(noDHW)

1. Review wiring information on page53 (120VAC out-

puts) and page54 (24VAC inputs).

2. e conguration at right uses the three input/output

pairs to receive thermostat inputs on P11-4/5, P15-1/2,

and P15-3/4; and circulator outputs on P2 as shown.

3. e factory default settings assign all inputs 1, 2 and3

to PRIORITY 2.

4. Choose the space heating system type that matches the

heating system during the WIZARD setup or manually

in the PRIORITY2 menu.

5. Use the factory default settings for the system type

chosen, or change if needed.

6. Factory defaults should work for other settings not

listed above.

1. Review wiring information on page53 (120VAC out-

puts) and page54 (24VAC inputs).

2. e conguration at right uses INPUT2 and3 for space

heating thermostats. INPUT1 uses the input from a

DHW aquastat.

3. e factory default settings assign inputs 1, 2 and3 to

PRIORITY 2. Keep inputs2 and3 assigned to PRIOR

ITY2. To set up PRIORITY2, choose the space heating

sys

tem type that matches the heating system during the

WIZARD setup or manually in the PRIORITY2 menu.

4. Assign INPUT1 to PRIORITY 1, which is factory

default congured for DHW applications.

5. Use the factory default settings for DHW and for the

heating system type chosen, or change if needed.

6. Factory defaults should work for other settings not

listed above.

P15, P11 and P2 are terminal strips on the EVG control.

1. Review wiring information on page53 (120VAC out-

puts) and page54 (24VAC inputs).

2. To shut down Space Heating during DHW operation:

Provide and connect relay R1 (120VAC coil with NC

contact) to interrupt the Zone controller’s ZC-ZR

(120VAC operating circuit).

3. e conguration at right uses INPUT2 for space

heating with the call for heat coming from the zone

controller (X-X). INPUT1 uses the input from a DHW

aquastat.

4. e factory default settings assign inputs 1, 2 and3 to

PRIORITY 2. Keep input2 assigned to PRIORITY2.

To set up PRIORITY2, choose the space heating sys

tem type that matches the heating system during the

WIZ

ARD setup or manually in the PRIORITY2 menu.

5. Assign INPUT1 to PRIORITY 1, which is factory

default congured for DHW applications. Wire the

DHW circulator to OUTPUT1.

6. Use the factory default settings for DHW and for the

heating system type chosen, or change if needed. Fac

tory defaults should work for other settings not listed

ove.
