7.5

Set-up mode

In this mode, you can set up the minimum opening angle of the proportional
valve. Below this limit, the proportional valve remains closed. This limit is
dependant on the pressure difference and the temperature. Define this lower
limit in order to keep the resolution loss in the drive low.
ATTENTION!
è In the Standard mode, hold down this key for about 2 seconds.
è Hold down this key for a further 2 seconds.
è Set the minimum opening angle between 0 and 100%.
NOTE
è To exit the Set-up mode, press down both keys at the same time

ATTENTION!
Operating Manual No. 800 209
è Always set the minimum opening angle when first
initialising the unit!
è In principle, always set the minimum opening angle at the
maximum pressure!
You will come into the Programming mode.
You will come into the Set-up mode, and the programming
symbol and the minimum opening angle last set will be
displayed (see 7.4).
=> You open the proportional valve
=> You close the proportional valve (cf. 7.4
Manual mode)
The minimum opening angle has been reached at the last
moment before the valve opens, i.e., immediately before the
start of the flow.
The unit saves the set values, and changes to the Standard
mode, i.e., the Programming mode is also exited.
You can remove the control unit from the compact temperature
controller, e.g., after programming, without affecting the set process.
The programmed values remain stored in the temperature
controller.
Protection class IP65 is only guaranteed with the housing
closed.
è For this reason, always replace the housing lid and screw
it down tightly
