I 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
7700
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".
