Cool Pad
The parameters that determine exactly how the COOL PAD function reacts are programmed in two
separate screens, (Setup/Outdputs/Ventilation/Coolpad and Ventilation Setting/CoolPad). Chore-Time
strongly recommends that the factory default settings be used, unless poor control of temperature during
pad operation is noticed.
Chore-Time also recommends that CTB service personnel is contacted before
changing the settings.
1. Select the Main menu button. Select the Venti-
lation Settings button.
2. Select the Cool Pad button.
3. Measure the number of seconds it takes for water to
start coming out of the holes in the pad system's top dis-
tribution pipe after turning on the COOL PAD manual
toggle switch. This should be entered as the "Water pre-fill time"
(Item 3) and is likely to be different
for the different system manufacturers. This amount of time is added to the water run time each repe-
tition because the top distribution pipe drains out during the off time of the on-off cycle.
4. Measure the number of seconds it takes for water to start dripping out the bottom of a dry pad after
the COOL PAD manual toggle switch is turned to the on position. This amount of time should be en-
tered as the "Time to wet dry pad"
(Item 4) , This will be less than the time to make the pad completely
soaked. When the actual water on time reaches this "Time to wet dry pad" value, the next step is to run
the water continuously, assuming that the temperature is above the Cool Pad Range at the next tem-
perature check point.
5. If water running on the pad continuously is not desired, then the "Max water allowed" value
(Item 5) , should be changed so that it is less than the repetition rate time. Once the temperature de-
creases back below the Cool Pad Range, the actual water on time will return to the "Time to wet dry
pad" value again. From there the water on time changes in the normal way, with 5 second changes ev-
ery 20 minutes, depending on the temperature check points.
6. Actual water on time - For information only. Showing the value makes it possible to create a graph
of it's variations if you have the PC connection (C-Central).
