Table 3.2 – Setup Mode Descriptions
Outdoor Reset
LBTHODLOD icon in the Numerical Display section refers to Outdoor Reset. When Outdoor Reset is Off, pressing the
Next button will move to the Rmt icon. When Outdoor Reset is On, pressing the Next button will move into the LBT,
HOD, and LOD displays, which will allow setting of the Low Boiler Reset Temperature, High Outdoor Reset Temperature,
and Low Outdoor Reset Temperatures.
Anti Short Cycle
ASC icon in the Numerical Display section refers to Anti Short Cycle. Whenever the burner is turned off due to no
demand, the anti short cycle timer is started and the burner remains in a Standby Delay condition waiting for this time to
expire. To adjust the time, use the up and down keys to cycle through the time in minutes.
x When Anti Short Cycle is activated ASC icon will be displayed Numerical Display.
Pilot Hold
Hold icon in the Numerical Display section refers to Pilot Hold Test. If parameter is enabled, the burner control sequence
will hold at 1 second into the Ignition state.
During Pilot Test Hold, a flame-out timer always starts at zero when the Ignition state is entered, then counts up toward 15
seconds while flame is off and down toward zero when flame is on. If it ever reaches 15 seconds of accumulated flame
out time then a lockout occurs.
The pilot test hold should be enabled prior to entering Ignition, since changes to parameters may require some seconds to
take effect. Similarly, when the hold is disabled the burner control may remain in the hold condition for a short time.
x When Pilot Hold Test is activated Hold icon will be displayed Numerical Display.
