12.2 MODE 1 & 2: SETPOINT OPERATION: VIEW DISPLAY
Mode 1 intended for hydronic heating. The set-point for inlet water control is pre-set to 180
re-set limit is set to 230°F. The inlet set-point can be adjusted, however the limit is fixed. In addition to the
auto reset limit the factory installs a manual re-set limit set to 250°F. The control turns on the appliance
pump and stages the appliance to maintain set-point target temperature at the appliance inlet
temperature whenever an external heat demand is present. Once the external heat demand is removed,
the control turns off the appliance and operates the appliance pump based on
Mode 2 is intended for hydronic heating. The set-point for inlet water control is pre-set to 180°F and the
auto re-set limit is set to 230°F. The inlet set-point can be adjusted, however the limit is fixed. In addition to
the auto reset limit the factory installs a manual re-set limit set to 250°F. The control turns on the appliance
pump and stages the appliance to maintain set-point target temperature at the appliance inlet temperature
whenever an external heat demand is present. Once the external heat demand is removed, the control
turns off the appliance and operates the appliance pump based on the purge feature. The control turns on
the appliance pump and stages the appliance to the set-point target temperature at the system
temperature whenever an external heat demand is present. Once the last appliance stage turns off and the
heat demand is still present, the control then operates the appliance pump based on the purge feature. In
this case, it is imperative that the system pump operates continuously in order to provide constant
circulation past the system sensor. The appliance pump then turns back on with the first stage of the
appliance. If the heat demand is removed, the appliance is turned off and the control operates the
appliance pump P1 based on the purge feature.
