◄ CONTINUED FROM PREVIOUS PAGE
Control Wiring (Option 3): Utilizing a Zone Panel
1. Set “DHWP on TT” (see programming section for instructions).
2. Set “C1 on TT” (default, see programming section for instructions).
3. Circulator-on and -off delay will only effect DHW zone.
4. A call for heat on TT (from the DHW zone) will change boiler set point to the high limit. All other zones will
heat to the reset temperature determined by the HeatManager.
5. Ensure that the zone panel and AquaSmart are powered from the same service switch.
