Option 01.3 – External profile select enable (0 - 2) LV3
This option parameter specifies whether the fuel profile select inputs (PB6 & PB7) are used for profile
selection, or whether they are available as general-purpose inputs.

When a profile is selected externally, this will override any fuel profile selection made from the display
keyboard. If no profile is selected externally (i.e. the inputs are open or not selected here), the fuel profile
selection can be chosen from the display keyboard. If used, it must be ensured that the digital input is not
used for any other function (option parameters 1.x, 16.x and 18.x).
When a fuel profile selection is removed (by opening the input switch), the control will continue to run on
the previously selected fuel profile – THE CONTROL WILL NOT TURN THE BURNER OFF.
Option 01.4 – Gas Valve Proof of Closure select (1 - 13) LV3
This option parameter is used to enable proof of closure switches to be monitored for the gas shut-off
valves. When enabled, POC for GAS uses digital input as specified by the number entered (1 – 13),
please note digital inputs 1-9 are low voltage and 12 & 13 are high voltage. If any digital input is used for
this function, ensure the same input is not selected for any other function (option parameters 1.x, 16.x and
18.x). Note: Inputs 10 and 11 do not physically exist as separate input pins, so they cannot be used.
NOTE: It is recommended that both the oil and gas proof of closure switches should be wired to separate
inputs. That is, when firing gas, the oil valve is proven closed and vice versa. However, if both
"proof of closure" switches are wired in series, option parameter 1.4 and 1.5 must be set for the
same input. For example, if the oil and gas proof of closure was wired from L1 (Live) to line
voltage input terminal PE4 (DI 12), option parameters 1.4 and 1.5 would be set to 12.
