Zoning with the SlimFit Control
(continued)
B. Zoning with ZONE VALVES, suggested applications
Two space heating zones (no DHW)
1. Review wiring information on page 60 (120VAC
outputs) and page 52 (24VAC inputs).
2. The configuration at right uses INPUT 2 and 3 for
space heating thermostats. INPUT 1 is reserved
here for configuring the operation of the system
circulator.
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. Use the factory default settings for the heating sys-
tem type chosen, or change if needed.
5. Assign INPUT 1 to AUX PUMP/OUTPUT. Then
select ANY INPUT BY ITS PRIORITY when
prompted for when to activate the output. This will
cause the system pump to run when either of the
zones calls for heat. Confirm that Priority 2 RUN
AUX PUMP/OUT is set to YES.
6. INPUT 1 (P11-4/5) cannot be used for a wired con-
nection (as shown at right) because it is being used
in the control setup to run the system circulator.
7. Factory defaults should work for other settings not
listed above.
The system must be equipped with a by-pass
pressure regulating valve. Flow can occur
with zone valves closed.
WMZV zone valve zone controller plus
DHW controlled by boiler, DHW piped
directly to boiler
P15, P11 and P2 are terminal strips on the control
1. Review wiring information on page 60 (120VAC
outputs) and page 52 (24VAC inputs).
2. The configuration 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.
3. 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.
4. The system circulator, wired to OUTPUT 2, will
turn on whenever there is a call for heat from the
zone controller.
5. Assign INPUT 1 to PRIORITY 1, which is factory
default configured 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.
