Any cycle can be converted to a heating
cycle by inserting a step after the fill, and
setting the end step condition to a
temperature (See Step 2 in the
illustration to the right).
Step 1 - Fill to a water level with hot
water. Heat is on, and will engage when
a minimum water level is met.
Watchdog timer of 9:00 allows time to
fill before an alarm is generated. Step 1
ends when the water level is reached.
Step 2 - Heat output is on. Watchdog
timer of 30:00 allows time to heat to the
required temperature before an alarm is
generated. Step 3 ends when the target
temperature is reached.
Step 3 - Heat output is on, Chemical 2
output is on, Relay 12 (injection flush) is
on (not required for machines with
plastic vacuum breaker). Step 3 ends
when a time of 1:00 elapses.
Step 4 - Top off step, same outputs as
step 1.
Step 5 - Heat output is on in order to
regulate temperature during the agitation
phase. Step 5 and the entire cycle are
complete when a time of 7:00 elapses.
