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.
