Display Valves

GE-CW valve

The start temperature for the GE/CW

valve is entered as a positive difference to

the room temperature setpoint. ➊

For the GE/CW valve you can adjust a

gradient, which determines the tempe-

rature range in which the valve opening

increases from 0 to 100%.➋

With the GE-off value you determine a

water temperature which establishes

the limit for GE-operation. If this value is

exceeded, the GE-operation is switched

off by closing the valve and stopping the

glycol pump. ➌

The actual water temperature is shown for

a better orientation.

Additionally you can prevent mixed opera

-

tion of Freecooling and compressor coo-

ling by setting the "Close at comp" value

to "1". (see Graphics below).
