Zoning with the EVG Control

A. Zoning with CIRCULATOR S, suggested applications
Three space heating zones (no DHW)
1. Review wiring information on page 56 (120VAC
outputs) and page 57 (24VAC inputs).
2. The confi 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. The 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.
Two space heating zones plus DHW piped
directly to boiler
1. Review wiring information on page 56 (120VAC
outputs) and page 57 (24VAC inputs).
2. The confi guration at right uses INPUT 2 and 3 for
space heating thermostats. INPUT 1 uses the input
from a DHW aquastat.
3. The factory default settings assign inputs 1, 2 and 3
to PRIORITY 2. Keep inputs 2 and 3 assigned to
PRIORITY 2. To set up PRIORITY 2, choose the
space heating system 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 confi 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.
WMCR circulator zone controller plus DHW
controlled by boiler , DHW piped directly to boiler
1. Review wiring information on page 56 (120VAC
outputs) and page 57 (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. The confi 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. The 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
system type that matches the heating system during the
WIZARD setup or manually in the PRIORITY 2 menu.
5. Assign INPUT 1 to PRIORITY 1, which is factory
default confi 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.
Factory defaults should work for other settings not
listed above.
