7.6 Level 1
7.6.1 Standby (ON)
Three operating modes can be selected, Display is
flashing.
0 = equipment on standby: pump(s), heating,
refrigeration unit OFF. Control unit and displays are
operating. The symbol in the display on the left is
alight.
1 = Equipment in operation (ON).
A = automatic operation standby and equipment ON
are selected by contact at socket 16N.
Contact closed = equipment ON.
Contact open = equipment OFF, standby.
View of socket (front) and plug solder face! Signal
approx. 5 V, 10 mA.
Do not use pin 3!
3-pin coupling connector Cat. No. EQS 048.
7.6.2 External control (CON)
External control can be activated here:
I = internal control, the equipment is controlled by the
outflow temperature.
E = external control ON, the control operates as
cascade controller from the external actual
temperature.
With external control switched on, line 1 of the display
automatically shows the external temperature. The
indicator field changes from INT to EXT.
The external actual temperature is normally sensed by
the Pt100 connected to socket 10S ( Section 7.5.2).
The external actual value can also be introduced as a
standard signal (socket 66S).
