Parallel Fan Heat On Delay
– The delay in reheat coming on after the zone has a
heating demand. If the
Term Type
is
Parallel
, this allows the fan time to use plenum air
to heat the space prior to bringing mechanical reheat. If the
Term Type
is
Single Duct
D:
,
we recommend that you set this value to 1 minute.
R:
15 minutes
0 to 30 minutes
DCV Max Vent Damper Pos
D: – The maximum damper position that the IAQ function can
override the damper to. When active, the damper modulates to the temperature
control position or the IAQ override position, whichever is greater.
R:
70%
0 to 100%
Heating Lockout Temperature
D: – Supplemental reheat is disabled if outside air
temperature exceeds this value. Supplemental reheat is enabled when the outside air
temperature falls below a fixed hysteresis of 2°F. This function is active only if there is
a valid network outside air temperature.
R:
70°F
-60 to 150°F

SETPOINT
Point Name/Description
Default/Range
Heating Capacity
D: – Used for Optimal Start, this is the rate at which the zone
temperature changes when the heating system runs at full capacity to maintain
designed occupied heating setpoint.
R:
5°F/hr
0 to 120°F/hr
Heating Design Temp
D: – The geographically-based outdoor air temperature at which the
heating system must run constantly to maintain comfort. This information is available
in ASHRAE publications and most design references.
R:
0°F
-100 to 150°F
Cooling Capacity
D: – Used for Optimal Start, this is the rate at which the zone
temperature changes when cooling system runs at full capacity to maintain designed
occupied cooling setpoint.
R:
5°F/hr
0 to 140°F/hr
Cooling Design Temp
D: – The geographically-based outdoor air temperature at which the
cooling syste
m must run constantly to maintain comfort. This information is available in
ASHRAE publications and most design references.
R:
100°F
-100 to 150°F
