BOILER DESIGN
The supply water temperature required for the boiler zones to heat the building
on the typical coldest day of the year. Recommendations:
70 to 200°F
•
High mass radiant floor = 120°F (50°C)
(21 to 93.5°C)
•
Low mass radiant floor = 140°F (60°C)
Default = 180°F
•
Fancoil or air handling unit = 190°F (90°C)
(82°C)
•
Copper fin-tube convector = 180°F (80°C)
•
Radiators = 160°F (70°C)
•
Low profile baseboard = 150°F (65°C)
Note: This item is only available when a boil water temperature has been
selected.
BOILER MINIMUM
(26.5 to 82°C)
The minimum allowed boiler target temperature and temperature at which the
mixing device begins to provide boiler protection against cold return water
Default = 140°F
temperatures. The variable speed pump operates at low percent output when the
(60°C) if BOIL
boiler supply temperature drops below this setting. Recommendations:
TYPE = 1STG
•
Condensing gas or electric boiler = OFF
•
Non-condensing gas and oil boilers = 140°F (60°C)
Note: This item is only available when a boil water temperature has been selected.
EMS1, or EMS2
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.
Default = 30
BOILER MOTOR SPEED
seconds
Time in seconds from full-close to full-open of modulating boiler actuator.
Note: Item is only available when BOIL TYPE is set to 0-10 or 4-20.
0 to 50%
BOILER MINIMUM MODULATION
Default = 0%
Minimum physical output to modulating boiler.
Note: Item is only available when BOIL TYPE is set to 0-10 or 4-20.
0:00 to 3:00
BOILER MODULATION DELAY
minutes
Modulating boiler stays at MIN MOD output for this length of time before beginning
to modulate to control temperature.
Note: Item is only available when BOIL TYPE is set to 0-10 or 4-20.
40 to 100°F
(4.5 to 38°C)
WWSD OCCUPIED
Default = 70°F
The system's Warm Weather Shut Down temperature during Occupied periods
(21°C)
or when a schedule is not used.
40 to 100°F
WWSD UNOCCUPIED
(4.5 to 38°C)
The system's Warm Weather Shut Down temperature during Unoccupied
Default = 60°F
periods.
(15.5°C)
Note: Item is only available when a schedule or User Switch is present on the
system.
INTERLOCK
Set the minimum delay between the heat pump switching from heat to cool or
cool to heat.
Note: The interlock delay only applies when the MODE is set to AUTO.
