Setpoint Configuration Without Outdoor Reset - FULTON Vantage VTG Series Installation And Operation Manual

Setpoint Configuration without Outdoor Reset


The Setpoint Configuration screen displayed is based on the option selected. Below is the Setpoint Configuration
screen without outdoor reset.

Setpoint Mode: Determines where the ModSync determines where the loop setpoint is generated from.
o
ModSync: The setpoint will be the user selected Normal Mode Setpoint or Setback Mode
Setpoint based on the setback schedule.
o
Remote SP: The setpoint will be determined by the 4-20mA signal input scaled from the system
and scaling screen.
o
BMS: The setpoint will be written by the Building Management System through the
communication protocol.

Minimum Setpoint: User selected value that will limit the minimum that the ModSync will allow the
setpoint to get to regardless of the setpoint mode. For example if the setpoint mode is in BMS and the
BMS is writing a 100°F setpoint to the ModSync but the Minimum Setpoint is set for 120°F then the
ModSync setpoint will be 120°F.

Maximum Setpoint: User selected value that will limit the maximum that the ModSync will allow the
setpoint to get to regardless of the setpoint mode. For example if the setpoint mode is in BMS and the
BMS is writing a 180°F setpoint to the ModSync but the Maximum Setpoint is set for 160°F then the
ModSync setpoint will be 160°F.

DHW Priority: In the event that the Heating Loop is also providing heat for Domestic Hot Water
production the ModSync comes equipped with DHW Priority logic. When Enabled, if the contact between
M1 and 1B (Please see your ModSync electrical drawing) is made the ModSync will enter DHW mode.

DHW Min Setpoint: If the ModSync is in DHW mode and the current setpoint is less than the DHW Min
Setpoint then the ModSync will raise the setpoint up to the DHW Min Setpoint until the ModSync is no
longer in DHW mode.
