The controller is equipped with 9 relays in total to which
loads (actuators) such as pumps, valves, mixers and auxi-
liary relays can be connected (A = normally open contact;
R = normally closed / break contact):
• Relays R1 ... R4 are semiconductor relays, designed for
pump speed control.
R1-A ... R4-A = normally open R1 ... R4
N = neutral conductor N
(common terminal block)
PE = protective earth conductor PE
(common terminal block)
• Relays R5 ... R8 are electromechanical
relays with change-over contact.
R5-A ... R8-A = normally open R5 ... R8
R5-R ... R8-R = normally closed R5 ... R8
N = neutral conductor N
(common terminal block)
PE = protective earth conductor PE
(common terminal block)
• Relay R9 is a floating / potential-free relay with change-
over contact:
R9-M = center contact R9
R9-A = normally open R9
R9-R = normally closed R9
Note:
If a heating circuit pump is controlled via the
internal heating circuit with relay 9, an insulated
jumper has to be run from the mains input L to
R9-M!
Please note:
Relays R1 to R4 are semiconduc-
tor relays for pump speed control.
A minimum load of 20 W (power
consumption of the consumer)
is required for faultless function.
The 4.7nF capacitor from the
accessory bag must be connected
in parallel to the respective relay
output if it feeds auxiliary relays,
motor valves, etc.
The minimum pump speed must
be set to 100% when auxiliary
relays or valves are connected.
