air flow. The discharge air temperature shall be limited to 100
Deg F.
4) The BAS shall limit the maximum cooling setpoints to 75 Deg F.
(adjustable) and the minimum cooling setpoint to 73 Deg F.
(adjustable).
5) The BAS shall limit the maximum heating setpoint to 72 Deg F.
(adjustable) and the minimum heating setpoint to 70 Deg F.
(adjustable).
6) If the room temperature rises 3 Deg F. (adjustable) above the
cooling setpoint, the BAS shall generate an alarm. If the room
temperature drops 3 Deg F. (adjustable) below the heating
setpoint, the BAS shall generate an alarm.
7) Convector shall be controlled in sequence with the reheat coil.
Convector valve shall open first, followed by the reheat coil
valve.
g. Warm-up Cool-Down Mode
1) When the central air handling unit is in the Warm-Up mode, the
BAS shall reverse the action of the VAV box so as the room
temperature drops below setpoint the box will modulate towards
maximum position and as the room temperature rises above the
setpoint the box will modulate towards minimum position. When
the Warmup mode is concluded the VAV box shall operate in the
same manner as during the Occupied Mode.
2) The BAS shall command the hot water reheat valve closed.
3) When the central air handling units is in the Cool-Down mode,
the VAV box shall operate in the same manner as during the
Occupied Mode except the heating shall be disabled.
h. Energy Consumption
1) The BAS shall monitor the supply air temperature to the VAV
Box, the VAV room temperature and the supply air flow in CFM.
2) The BAS shall monitor and totalize the energy consumption of
the VAV zone in Btuh.
i. VAV Room Sensor
1) The VAV Room Sensor shall provide room temperature value to
the controller.
2) The VAV Room Sensor shall be supplied in the following
manner:
a) Tamper-resistant with tenant override to allow timed
override of unoccupied to occupied mode of operation.
b) LED indication of override state.
