Supply setpoint temperature
In this parameter window it is specified how the supply setpoint temperature for the cooling distribution
circuit is calculated.
Supply temperature control
Options:
No (checkbox cleared)
Yes (checkbox selected)
On the selection of the Yes option, the ASM calculates the supply setpoint temperature for the cooling
distribution circuit and sends the value calculated to the cooling distribution circuit controller via the group
object. Other parameters define how the calculation is undertaken.
Selection of Yes option:
Dependent parameter(s):
Supply setpoint temperature source
Options:
ASM input socket
WebUI Input
BACnet input object
Calculated weather compensated
This parameter determines how the supply setpoint temperature is determined for the cooling
distribution circuit. This setpoint is sent to the cooling distribution circuit controller via the group
object.
• ASM input socket: The supply setpoint temperature received via the input socket on the ASM is
used. This is an ASM multiple socket on which the lowest value present is used.
• WebUI Input: The supply setpoint temperature is set on the web user interface for the ASM.
• BACnet input object: The supply setpoint temperature received via the BACnet object for the
ASM is used.
• Calculated weather compensated: The module calculates the supply setpoint temperature
currently required based on the outside temperature.
