1.2.2 Actuators
(pumps, valves etc.)
The controller is equipped with 7 relays to which loads
(actuators) such as pumps, valves and auxiliary relays
can be connected (A= normally open contact; R =
normally closed / break contact):
• Relays R1 ... R6 are semiconductor relays:
R1 ... R3 = normally open R1 ... R3
(designed for pump speed control)
R4 ... R6 = normally open R4 ... R6
N = neutral conductor N
(common terminal block)
PE = protective conductor PE
(common terminal block)
• Relay R7 is a potential-free (floating) relay with
change-over contact:
R7-M = center contact R7
R7-A = normally open R7
R7-R = normally closed R7
Note:
The minimum pump speed must be set to 100% when
auxiliary relays or valves are connected
.

ATTENTION!
High-efficiency pumps can be connected to
semiconductor relay outputs only!
