Fixed "Vend" Pricing
A dryer set up for "Fixed Cycle" operation can only
accept additional time accumulated by increments
equal to the length of a complete dry cycle.  A
maximum of 99 minutes may be purchased; no
additional credit is given when 99 minutes is in the
display.

Accumulator Pricing
If the price is equal to the value of coin 1, then
accumulator mode is in effect (stacked models also
require Fixed Cycle with Top Off option to be
selected).  Cycle time can be purchased one coin
at a time (PD and PS models) up to the maximum
time of 99 minutes.  While in accumulator pricing,
stacked machines will credit all money to a cycle
with a single button press.

Fixed Cycle With Top Off Pricing
A dryer set to offer "Top Off" capability will allow
time to be added to an existing dry cycle in
increments equal to the number of minutes of dry
time per quarter (coin 1), up to 99 minutes,
regardless of the cost required to start the machine.
No credit is given for coins or debit inputs entered
when the control is displaying 99 minutes.

PR Models:  In Enhanced Debit Mode, the Top Off
price can be set independently.  (See VALUE OF
COIN 2), and the top off time is calculated
according to the following equation:

top off price

=

top off time

full cycle price

=

full cycle length

Penny increment offset is not applied to top off
purchases.
Free Cycles and PN Models
This is established by setting the cycle price to
zero.  When this happens, "select cycle" will appear
rather than a cycle  price.  Any cycle started as a
free cycle will automatically terminate when the
door is opened.

Debit-Card Ready
This appliance is debit-card "cable ready."  It will
accept a variety of debit card systems, but does
NOT come with a debit-card reader.  Connection to
the control board is by means of a Molex brand
connector (housing and terminals.)  See your
distributor for appropriate connector part numbers.
