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)
⌯ = ground terminal ⌯ (common terminal block)
• Relay R7 is a potential-free (oating) relay with change-
over contact:
R7-M = center contact R7
R7-A = normally open R7
R7-R = normally closed R7
In all systems with after-heating, R7 switches in parallel to
R3 (via function block) in order to provide boiler demand
if necessary.

The controller is equipped with the RESOL VBus
®
for
data transfer with and energy supply to external modules.
The connection is carried out at the two terminals marked
“VBus
®
“ (either polarity). One or more RESOL VBus
®
modules can be connected via this data bus:
• RESOL WMZ, calorimeter
• RESOL large display / Smart Display
• RESOL Datalogger
• RESOL heating circuit modules HKM (up to 3 modules)

Note:
The minimum pump speed must be set to 100 %
when auxiliary relays or valves are connected.
