ACF1

• Heat pump unit selected but 4-way valve not configured

• Wrong configuration of defrost parameters dF22 and dF23

ACF2

• Condensing control enabled but condenser probes not configured

(one probe per circuit with 2 separate circuits, at least 1 probe for common

cond.)

• Fan proportional control algorithm not respected:

FA09 + FA11 + FA12 < FA10

FA12 < FA13

FA07 < FA15 < FA08

• Fan proportional control algorithm not respected and pump enabled:

FA18 + FA21 + FA20 < FA19

FA21 < FA22

FA16 < FA23 < FA17

• Fan ON - OFF regulation algorithm not respected:

FA09 < FA10

• Fan ON - OFF regulation algorithm not respected and pump enabled:

FA18 < FA19

• If the defrost is enabled and no evaporating/condensing probes configured.

• With triac regulation (CF68, CF69 = 2) the power supply configuration is

continuous control (CF63 = 2)

ACF3

• Two relays, or two digital inputs, or two analog inputs are configured with

the same function or without the necessary resources (es. compressor 3

overload but compressor 3 relay not configured)

ACF4

• CF59 = 1 and none digital input configured as Chiller request or Heat

Pump request

• CF59 = 2 and none probe configured as external temperature probe

• Unit configured as Heat pump and rack compressorr unit enabled (Cr01≠0)

• CF03 = 1 and wrong configuration of the digital input or digital output for

condensing unit unit

ACF5

Circuit # 2 not configured but at least one of its resources are present (e.g.:

solenoid

-down valve, heaters, inversion valve, fan, recover

, etc

)
