the typical coldest temperature of the year where the building is located. This temperature is used when doing heat loss calculations for the building.

Boiler Design (BOIL DSGN) – The BOIL DSGN temperature is the water temperature required to heat the boiler zones when the outdoor air is as cold as the OUTDR DSGN temperature.

Warm Weather Shut Down (WWSD) – When the outdoor air temperature rises above the WWSD setting, the control turns on the WWSD segment

in the display. When the control is in WWSD, the Dem segment is displayed if there is a heat demand. However, the control does not operate the heating system to satisfy this demand. The control does respond to a setpoint demand and operates as described in the Reset Override section (next).

Reset Override (SETPOINT DEMAND) – This is used when override of the outdoor reset curve is needed, such as when an indirect water heater is served by the heating system. A setpoint demand is required whenever heat is required for the setpoint load. The setpoint demand overrides the reset water temperature. The control turns on the Setp Dem pointer in the display. The control energizes the pump (on pump- mounted boilers), energizes the Pmp-Pmp terminals, and turns on the boiler pump segment in the display.
