ƒ Setpoint
The boiler or multiple boiler system will maintain supply water temperature
based on a setpoint temperature. This setpoint can come from a variety of
sources, including by calculation from an outdoor air temperature sensor, a
remote signal from the Building Management System (BMS), or from a static
manually entered setpoint.
` SETPOINT CONFIGURATION
The Setpoint Source screen allows for the selection between the various setpoint
sources available.
When in Outdoor Reset mode, the control will automatically calculate the
hydronic loop setpoint based on the settings configured on the Outdoor Reset
screen.
BMS Analog will monitor either the 4-20mA or 0-10VDC contacts for a remote
setpoint signal; the BMS Analog screens are used for the linearization settings for
the control signal.
When in BMS Network mode, the control will maintain setpoint based on the
Modbus RTU write point. Protocol conversion gateways are available for alternate
communication protocols including BACnet and LonWorks.
` OUTDOOR RESET
Outdoor air reset curves are configured through the Outdoor Reset screens. The
normal (occupied) setpoint curve and the setback (unoccupied) setpoint curve
are configured through separate screens.
The hydronic loop temperature setpoint will be calculated based on configured
outdoor air and setpoint high and low temperature values. When the outdoor air
temperature reaches a warm weather shutdown Outdoor Air Cutoff temperature,
the boilers will be disabled until outdoor air temperature has decreased by the
value assigned in the Cutoff Reset.
` BMS ANALOG (4-20MA AND 0-10VDC)
High and low setpoint values must be assigned for correct linearization.
ƒ Scheduling
The Scheduling system allows for the operator to configure when the normal
(occupied) setpoint will be maintained. When outdoor reset is enabled, the
normal setpoint curve will establish setpoint during these time frames with the
setback (unoccupied) setpoint curve establishing setpoint for all other times. See
the Outdoor Reset screen in Setpoint.
ƒ Trending
Trending data is continuously recorded by the control and can be enabled or
disabled by the operator. Tap the "Next Curve" button to navigate through data
types.
