Q7 SET INTAKE PRE-PURGE
When operating in ‘intermittent’ mode it is important to set the pre-purge. Pre-purge is the period from when there is a
call for heat until the control allows the appliance to start assuming the supply fan is operating at the proper capacity. The
setting can be anywhere from 0 to 1800 seconds.
There is no need to set this value, if the control is used to control the draft or exhaust pressure.
Q8 SET INTAKE POST-PURGE
When operating in ‘intermittent’ mode it is important to set the post-purge. Post-purge is the period from when the appli-
ance shuts down until the control allows the fan to shut down assuming there are no more products of combustion in the
chimney system. The setting can be anywhere from 0 to 1800 seconds.
There is no need to set this value, if the control is used to control the draft or exhaust pressure.
Q9 ROTATION CHECK
There are two values available “ON” or “OFF”.
In the ON mode, the control will activate all fans connected to the control when turned on, and operate them at a very low
speed so proper rotation can be easily veried when 3-phase motors are used. If improper rotation is experienced appro-
priate action can be taken. Once proper operation has been veried, press the RESET button to accept all settings.
The above procedure is only required during the initial installation or if a motor or variable frequency drive has been
replaced.
If a power failure has occurred there is no need to check rotation and the RESET button can be pressed.
In the OFF mode, the control does not activate all fans in low speed mode but will let them operate at any speed setting.
OFF mode can be used after the initial installation.
To access the Quick-Menu, press the PROG key for 3 seconds. The gure on page 16 shows the sequence of programming.
