▼ Input / Output Testing Functions

Input/output testing is used to ensure that the connected components are in working order.
Relay Output Testing
Selection of a setting from relay testing closes the corresponding relay and therefore switches on the connected
component. This makes it possible to check that the relays are in working order and that the wiring has been
performed correctly.

7700 Relay test
This consists of instructing the regulator's relays one by one and checking their outputs. This enables you to
check that the relays are working and that the cabling is correct. Check that each appliance in the installation is
operating correctly.
0: No test, 1: Everything is on STOP, 2: Relay output QX1 : heat pump CC1 (if 1 circuit ) or heat pump CC2 (if 2 circuits),
3: Relay output QX2 : Electrical back-up (1st stage) or Boiler connection distribution valve,
4: Relay output QX3 : Electrical back-up (2nd stage) or Boiler connection contact,
5: Relay output QX4 : DHW distribution valve, 6: Relay output QX5 : DHW Electrical back-up, 7: Relay output QX6 ,
8: Relay output QX31 : Heat circ mix valve open Y1 (or control pilot-wire), 9: Relay output QX32 : Heat circ mix valve close Y2,
10: Relay output QX33 : heat pump CC1 if 2 circuits (mixed circuit, the less hot), 11: Relay output QX34,
12: Relay output QX35 : Swimming pool distribution valve, 13: Relay output QX21 module 1, 14: Relay output QX22 module 1,
15: Relay output QX23 module 1, 16: Relay output QX21 module 2, 17: Relay output QX22 module 2,
18: Relay output QX23 module 2, 19: Not used, 20: Not used, 21: Not used.
The display shows the "Key" symbol. Pressing the Info button displays "Error 368".
Warning: The component being tested is receiving electrical power throughout the test.
Warning
During testing of an output, the heat pump is stopped, all outputs are "off " and only the controlled output is on.

Input test EX1-3
Line Nr Programming line
7911 Input EX1
7912 Input EX2
7913 Input EX3
By selecting a setting from input test EX1-3, the relevant
input will be displayed, enabling it to be checked.
Display of 0 V means that there is no voltage and the
respective input is currently inactive. Display of 230 V
means that voltage is present at the respective input so
that it is activated.
