7.1 Control panel
A1 Control panel for setting the type of control
see para. 7.2
A2 Keys for setting (delivery height)
with illuminated symbols (LED) to display delivery height
and delivery flow,
see para.7.3
LED 1 Display control curve characteristics set (phase)
LED 2 Display the current delivery height V (25…100%)
LED 3 Biral impeller displays the status of the pump
see para. 7.8
B Socket for Remote Adapter
Warning
There is a risk of burning!
For high media temperatures the pump
may become so hot that only the keys may be
touched.

7.2 Types of control (A1)
Cycle
of the control type
Operating key
Controlled operation: proportional pressure (pp)
may be used in the following systems:
– Dual pipe systems with thermal valves and
– Long stretches of pipe
– Valves with large working area
– High pressure loss
– Primary circulation pumps with high pressure loss
Controlled operation: constant pressure (cp)
may be used in the following systems:
– Dual pipe systems with thermal valves and
– Delivery height < 2m
– Natural circulation (formerly gravity heating)
– With very low pressure loss
– Primary circulation pumps in systems
with low pressure loss
– Floor heating with thermostatic valves
– Single pipe heating
Non-controlled operation: constant speed (cs)
The operating point can be optimally set by adjusting
the speed (key A2) optimal.
May be used for systems with constant volume flow:
air-conditioning applications, heat pumps and boiler
feed pumps, etc.
