Description
BOILER DESIGN
The supply water temperature required for the boiler
zones to heat the building on the typical coldest day
of the year. Recommendations:
High mass radiant floor = 120°F (50°C)
Low mass radiant floor = 140°F (60°C)
Fancoil or air handling unit = 190°F (90°C)
Copper fin-tube convector = 180°F (80°C)
Radiators = 160°F (70°C)
Low profile baseboard = 150°F (65°C)
BOILER MINIMUM
The minimum allowed boiler target temperature and
temperature at which the mixing device begins to
provide boiler protection against cold return water
temperatures. The mixing valve or variable speed
injection pump operate at low percent output when
the boiler supply temperature drops below this
setting.
Recommendations:
Condensing gas or electric boiler = OFF
Non-condensing gas and oil boilers = 140°F (60°C)
Note: If Boiler Type is 0-10 V (dc), 4-20 mA, EMS1
or EMS2, this setting is defaulted to Off. The mixing
device does not provide boiler protection when Boiler
Type is set to EMS1 or EMS2.
BOILER MOTOR
The time required for the modulating actuating motor
to fully open the gas valve or ramp the burner fan
from off to full speed on a modulating boiler. Set to
30 seconds unless otherwise recommended by the
boiler manufacturer.
Note: This item is only available when the Boiler
Type is 0-10 V (dc) or 4-20 mA.
MINIMUM MODULATION
The minimum percent modulation of the boiler
burner.
Note: This item is only available when the Boiler
Type is 0-10 V (dc) or 4-20 mA.
MODULATION DELAY
Delay time between the burner firing and the boiler
releasing to modulation.
Note: This item is only available when the Boiler
Type is 0-10 V (dc) or 4-20 mA.
FLUSHING
Set to On when a domestic hot water tank is used
to heat the building. When On, the control ensures
that each zone is operated at least once daily to
prevent stagnation.
