How to Modulate Water Valves to Regulate Incoming Water Temperature
BNCJUP03.C14 0000191934 C.2 D.2 A.8 1/2/20 1:16 PM Released
When programming a thermo-modulated temperature for a bath using both hot and cold water
valves, the relationship between the desired temperature and the temperature of a split fill (hot
and cold valves open simultaneously) is important.
If the desired temperature is hotter than the normal split temperature, a faster, more accurate fill
with a more constant temperature is achieved by programming the hot water valve open (H=1)
and the cold water valve to open only to lower the fill temperature (C=3).
If the desired temperature is colder than the normal split temperature, similar results can be
achieved by programming the hot water valve to open only to raise the fill temperature (H=2) and
the cold water valve to remain open constantly (C=1).

How to Use Cooldown

A cooldown bath is used to gradually lower the temperature of goods (usually synthetics and
blended fabrics) to reduce the chance of setting wrinkles. When a cooldown is programmed, the
drain type for the previous bath step is automatically changed to
Do Not Drain
, so the goods are
not cooled too quickly by coming in direct contact with the incoming cooldown water.
These items are required before the controller will allow you to program a cooldown step:
1. The machine must be equipped with a separate
cooldown water valve
. This valve and its as-
sociated piping reduces the flow of cold water into the machine so the temperature falls
gradually.
2. The machine must be configured for temperature control (
Temp Control
= YES). Detailed
configure instructions are provided elsewhere in the manual. See the table of contents.
3. The machine must be configured for cooldown (
Cooldown Error
= 1, 2, or 3).
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). Fail-
ure 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 spe-
cific temperature is programmed (shown underlined).
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 cool-
down will always be changed to one minute (MMQ = 010). Any
valid
bath
step type may be used here (T = 1, 2, or 3)
