BST Upld Timer (Span = 0 and 30 - 9999, Default = 0)
The BST Upld Timer specifies the frequency of BST OnAER Data Logging transmissions.
This value defines the time, in seconds, between successive OnAER Data Logging
transmissions from the BST Master to either an Internet destination or and SD-Card.
The default value is 0, which disables the periodic OnAER data transmissions.
This value can be varied from 30 seconds to 9999 seconds.
Example: Setting the BST Upld Timer to 40, will cause the BST Master to transmit OnAER data
every 40 seconds.
9.6 BST Setup
The BST can be configured for any of the following three modes of operation:
• Constant Setpoint
• Remote Setpoint
• Outdoor Reset
NOTES
The standard boiler parameters such as: Unit Type, Unit Size, Fuel Type,
etc. should have been set at the factory.
On each boiler, enter The Modbus Comm Address of each boiler in the
Comm Address Item in the Setup Menu.
Select the single option that suites your installation and then complete the instructions in the
corresponding sub-section below.
Constant Setpoint (choose option 1 or 2)
This is the BST Default mode of operation, used when a fixed header temperature is desired.
Option 1 – Direct Wired Header Complete section 9.6.1
OR
Option 2 – Modbus Header Complete section 9.6.2
Header Temperature Sensor Selection
If the BST Master Fail Rollover (BST Auto Mstr) feature is enabled, The Header
Temperature Sensor MUST be installed as a Modbus Header Sensor using the Modbus
Temperature Transmitter (see Section 9.6.2 Constant Setpoint with Modbus Wired
Header Sensor, below).
Note! If no header sensor is installed, the sensor fault message will appear on the C-More
Control Panel and the unit will not operate.
If the BST Master Fail Rollover (BST Auto Mstr) feature is disabled, it is recommended that
the Header Temperature sensor be directly wired to the FFWD Temp sensor input of the
Master unit (see Section 9.6.1 Constant Setpoint with Direct Wired Header Sensor,
below).
