If specied, divide a read value by this to obtain the actual value – Multiply desired value by this before writing
For variables that specify them, if a read value is a special value (32000 - 32005), do not divide by ‘MULT'
Strings are packed 2 characters per register, most signicant byte rst
Multi-register values are stored big endian (rst register x 65536 + second register = value)
All variables are stored as ‘Holding Registers’ MODBUS functions :
• ‘Read Holding Registers’ (function code 3),
• ‘Write Single Register' (function code 6),
• and ‘Write Multiple Registers’ (function code 16) are supported
All variables with multiple UOM’s depend upon the value of ‘Input Mode’ to determine which to use
Use 'Burner Differential' and 'Burner' when 'Output Mode' is set to Burner
Use 'Valve' when 'Output Mode' is set to Motorized Valve
Use 'Boost' when 'Boost Mode' is set to Vari Boost or Vari Boost + ESD
The HWR Platinum has a schedule, which is 7-days, 4 day/night pairs per day For example: Register
38 is the rst DAY schedule of Monday; Register 39 is the rst NIGHT schedule of Monday; Register 46
is the rst DAY schedule of Tuesday; Register 47 is the rst NIGHT schedule of Tuesday and so on

If specied, divide a read value by this to obtain the actual value – Multiply desired value by this before writing
For variables that specify them, if a read value is a special value (32000 - 32005), do not divide by ‘MULT'
Strings are packed 2 characters per register, most signicant byte rst
Multi-register values are stored big endian (rst register x 65536 + second register = value)
All variables are stored as ‘Holding Registers’ MODBUS functions :
• ‘Read Holding Registers’ (function code 3),
• ‘Write Single Register' (function code 6),
• and ‘Write Multiple Registers’ (function code 16) are supported
All variables with multiple UOM’s depend upon the value of ‘Input Mode’ to determine which to use
Use 'Burner Differential' and 'Burner' when 'Output Mode' is set to Burner
Use 'Valve' when 'Output Mode' is set to Motorized Valve
HT# 059266-00A
Use 'Vari-Boost Adjustment' when 'Boost Mode' is set to Vari-Day or Vari+ESD Use
'Manual Boost Time' when 'Vari-Boost Adjustment' is set to Manual Boost
'Boiler Status' range changes with 'Boiler Type' For example: when 'Boiler Type' is set to 0,
'Boiler Status' range is 0 to 1; when 'Boiler Type' is set to 1, 'Boiler Status' range is 0 to 2
Use 'Day Heat Adjustment', ' Fast Cycle', 'Night Heat Adjustment', and
'Heat Establish Pressure' if 'Operation Mode' is set to 0
Use 'Setback' if 'Operation Mode' is set to 1
Use 'Last Stage Hold', 'Min Runtime', 'Purge', 'Reaction Time', 'Standby Delay' when 'Logic Mode' is set to 0
Use 'Reaction Time' when 'Lead Stage Rotation Mode' is set to 0
Use 'Throttle Range' when 'Logic Mode' is set to 1
Use 'Max Target' when 'Control Mode' is set to 0
The MPCQ Platinum has a schedule, which is 7-days, 4 day/night pairs per day For example: Register
38 is the rst DAY schedule of Monday; Register 39 is the rst NIGHT schedule of Monday; Register 46
is the rst DAY schedule of Tuesday; Register 47 is the rst NIGHT schedule of Tuesday and so on
