HVAC Configuration Tab
The
HVAC Configuration
tab allows a user to configure, Setpoints, Humidification, Compressor and
Cooling, Heating, and outside air dampers parameters. Also low limit alarms, optimum start/stop, and
fan and equipment delays can be adjusted. A brief description of each type of configuration parameter
is outlined below.
Configuring Space Temperature Settings
The
Setpoints Configuration
subsection contains the heating and cooling setpoints for the occupied,
standby and unoccupied modes. The table below gives a brief description of each type of setpoint.
Setpoint
(heating/cooling)
Description
Occupied
The limits between which the temperature is to be maintained by the controller when it is
in Occupied mode. This temperature range should be comfortable to building occupants.
Standby
The limits between which the temperature is to be maintained by the controller when it is
in Standby mode. In Standby mode, the temperature is usually allowed a larger amount
of variance than in Occupied mode. Still, it is maintained at a value close enough to the
occupied setpoints so that it can be varied quickly for occupancy.
Unoccupied
The limits between which the temperature is to be maintained by the controller when it is
in Unoccupied mode. If the temperature passes these limits, the system reacts to bring
the temperature back within these limits. In Unoccupied mode, the space temperature is
usually allowed a larger amount of variance than in Occupied mode, thereby lowering
operating costs.
Discharge Temperature Low Limit Alarm
From this subsection, the lower limit for the discharge temperature can be set to an alarm.
