Generally applicable rules
for the proper use of this unit:
When used for floor and wall heaters: here, a safety thermostat must be used just as
with conventional heater controllers. It has to switch off the heating loop pump if there
is overheating regardless of the output from the controller to prevent indirect damage
from excess temperatures.
It is necessary to set all „
Required settings
“ mentioned in the hydraulic diagrams.
Relay output A4 can be made potential-free by resetting the jumpers.
All pr1 (+2, +4, +8)" indicates that the selected program number can be in-
creased by the sum total of these numbers.
Example:
Diagram 0, program 1 = pump-valve system
All pr2: program also includes the boiler temperature T5
1+2 = 3
pump-valve system including the boiler temperature T5
Linking of outputs
: Possibility to cancel out the numbered outputs listed in the pro-
gram diagram against each other (e.g. A1 with A2, A1 with A3 or A2 with A3, etc.). By
this means it is possible to assign the speed output at will. Addition of following num-
bers to the selected program number:
Linking of outputs
A1 with A3 ..... +100 A1 with A4 ..... +200
A2
with
A3
..... +300
A2
with
A4
..... +400
A1 with A3 & A2 with A4 ..... +500 A3 with A4 ..... +600
Program selection
The following hydraulic diagrams are basic functions. Changes resp. additional functions are
described and defined by program numbers. The program number is the most important key
to correct function of the control system. Only by input of this number the controller knows,
which controlling business has to be done.
The program number is selected in the switch position
