x Select Disable to disable DHW loop high limit
This parameter enables or disables the DHW high limit function. It must be disabled when the DHW input is used as a
switch to indicate DHW demand.
5-6.2 To Change DHW High Limit Setpoint
Configure High Limits DHW High Limit Setpoint Textbox (Default: 200ͼF)
x Type in desired temperature between 32ͼF and 240ͼF (0ͼC and 115ͼC)
If the DHW temperature reaches the value given by this parameter then a response will occur.
5-6.3 To Change Outlet High Limit Setpoint
Configure High Limits Outlet High Limit Setpoint Textbox
(Default: 240ͼF for H and 200ͼF for HLW)
x Type in desired temperature between 32ͼF and 240ͼF (0ͼC and 115ͼC)
If the outlet temperature reaches the value given by this parameter, a response will occur.
5-6.4 To Change DHW High Limit Response
Configure High Limits DHW High Limit Response Textbox (Default: Lockout)
x Select Recycle & Hold for DHW loop high limit response
x Select Lockout for DHW loop high limit response
If Recycle & Hold is selected then the burner control recycles and holds until the DHW temperature is falls below the
DHW high limit setpoint minus 5F.
5-7 Stack Limit Related Configuration
5-7.1 To Enable Or Disable Stack Limit
Configure Stack Limit Stack Limit Textbox (Default: Disable)
x Select Enable Dual Safety sensor to enable Stack limit
x Select Disable to disable Stack limit
This parameter enables or disables the entire stack temperature limit function.
5-7.2 To Change Stack Limit Delay
Configure Stack Limit Stack Limit Delay Textbox (Default: 5m0s)
x Type in desired time between 0 to 5 minutes
This parameter provides the delay time for the Stack limit.
5-7.3 To Change Stack Limit Response
Configure Stack Limit Stack Limit Response Textbox (Default: Recycle & Delay)
x Select Lockout to lockout in event of Stack limit
x Select Recycle & delay to recycle and delay in event of Stack limit
For Recycle and Delay, the burner control recycles and holds while waiting for a delay (see the Stack Limit Delay
parameter) to expire, and after the delay it tries again.
5-7.4 To Change Stack Limit Setpoint
Configure Stack Limit Stack Limit Setpoint Textbox (Default: No Valve)
x Type in desired temperature between 32ͼF and 266ͼF (0ͼC and 130ͼC)
If the stack temperature exceeds the temperature given by this parameter then the response defined for the Stack
Limit Response parameter will occur. As the temperature approaches this limit, the Stepped Modulation Limiting
function is active.
