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.
FIGURE 23 – SETPOINT CONFIGURATION WITHOUT OUTDOOR RESET
Setpoint Mode:
Determines where the ModSync® determines where the
loop setpoint is generated from.
»
ModSync®:
The setpoint will be the user selected Normal
Mode Setpoint or Setback Mode Setpoint based on the setback
schedule.
»
Remote SP:
The setpoint will be determined by the 4-20mA
signal input scaled from the system and scaling screen.
»
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.
