Parameter
Val
State
Configuration
ok
The configuration is correct.
ko
The configuration of the digital inputs or hardware is incorrect. Check the ext.
Inputs in the factory menu. (eg if the same function is configured for several
inputs) or Hardware (Hw evo-compact-> el.water).
Communication
ok
The communication between the cards in the machine and the remote control
panel works correctly.
ko
Problem in the communication between the cards and the remote panel:
1) check the electrical connections between the electronic board and the re-
mote panel (see electrical diagram).
2) If the problem persists, check electrical connections between the two cards
(see electrical diagram).
3) If the problem persists, check the position of the dip switch on both cards.
For a unit: X540 only 1 = on; X531 only 2 = ON; X541 all off.
4) If the problem persists, replace the electronic card.
5) Check that the parameter Hw (factory menu) is correctly configured for the
unit in use.
Outdoor air temperature sensor works correctly.
Te (external)
ok
Problem in the outdoor air temperature sensor:
ko
1) check the electrical connections of the temperature probe (see electrical diagrams).
2) If the problem persists, replace the temperature probe.
3) If the problem persists, replace the electronic card.
Tr (return)
ok
Return air temperature sensor works correctly.
ko
Problem in the return air temperature sensor:
1) check the electrical connections of the temperature probe (see electrical diagrams).
2) If the problem persists, replace the temperature probe.
3) If the problem persists, replace the electronic card.
Tx (expelled)
ok
Expelled air temperature sensor works correctly.
ko
Problem in the expelled air temperature sensor:
1) check the electrical connections of the temperature probe (see electrical diagrams).
2) If the problem persists, replace the temperature probe.
3) If the problem persists, replace the electronic card.
Ti (input)
ok
Introduced air temperature sensor works correctly.
ko
Problem in the air temperature sensor introduced
1) check the electrical connections of the temperature probe (see electrical diagrams).
2) If the problem persists, replace the temperature probe.
3) If the problem persists, replace the electronic card.
It is present only if the air after-treatment management is configured with
water coil (Factory menu).
Tw (water)
ok
Temperature sensor in the water coil works correctly.
ko
Problem in the air temperature sensor entered:
1) check the electrical connections of the temperature probe (see electrical diagrams).
2) If the problem persists, replace the temperature probe.
3) If the problem persists, replace the electronic card.
