2. The machine must be configured for temperature control (Temp Control = YES) as described
in Section 2.3.4.2.
3. The machine must be configured for cooldown (Cooldown Error = 1, 2, or 3) as described in
Section 2.3.4.2.
4. The bath step with the high temperature must immediately precede the cooldown step, and it
must have a temperature programmed in degrees (for example, 180 degrees Fahrenheit).
Failure to program a temperature in the bath preceding a cooldown results in an error message.

This is a typical step preceding a cooldown step. Note that a
specific temperature is programmed (shown in bold).
A cooldown is programmed as a separate bath step following the bath in which the cooldown is
desired. In the cooldown step, command a desired cooldown temperature with all water valves
programmed off (0). The E-P Plus
®
control automatically inserts a no drain in the previous bath
and 010 in MMQ for the cooldown step, for a step time of 1:00.

This is a typical cooldown step. Note that all configured water
valves are programmed off. The programmed step time for a
cooldown will always be changed to one minute (MMQ = 010).
Any valid bath step type may be used here (T = 1, 2, or 3)
Note 2: The commanded cooldown temperature must always be at least 15 degrees Fahrenheit (8 degrees
Celsius) hotter than the hottest ambient temperature or the hottest cold water temperature that will be
encountered. If this rule is not followed, achieving the desired cooler temperature may take a long time, or
even be impossible.
During operation, the cooldown bath step starts immediately when the previous (high-temperature)
bath ends.
1. The cooldown valve opens when the cooldown step begins. The cooldown valve does not close
until the end of the cooldown step.
2. When high water level is achieved, the drain opens until the water level falls below high level,
then the drain closes.
3. The drain continues to open and close as needed to maintain high water level.
4. The step timer starts 15 seconds after the desired cooldown temperature is achieved. The timer
runs for one minute.
