* G17 parameter >> Three defrost modes are available:
 G17 = EL → Defrost through electrical heater
 G17 = in → Hot gas defrost
 G17 = pulse → Pulse / natural defrost
** G23 parameter >> Defrost interval mode:
G23 = nu (0) → Defrost functionality not used

G23 = in (1) → Defrost in intervals G18

 G23 = rtC (2) → Enables defrost for RTC (real clock time), allows timing of defrost
cycles with G28 – G41
*** G24 parameter >> Display during defrost:
 G24 = DEF (0) → Display shows "DEF" for defrost
 G24 = SET (1) → Display shows "G02" parameter value = Case temperature setpoint
 G24 = IT (2) → Display shows display case temperature value
 G24 = RT (3) → Display will stay in standard operation
**** G42 parameter >> Evaporator fans function:
 G42 = cn (0) → will switch On and Off with the compressor, Off during defrost
 G42 = on (1) → Fans On, even if the compressor is off, Off during defrost
o
After defrost, there is a timed fan delay allowing for drip time, set by means of the
"G55" parameter.
 G42 = cy (2) → fans will switch On and Off with the compressor and On during defrost
 G42 = oy (3) → fans will run continuously also during defrost
Manual defrost
Please check settings for evaporator fans. The XCM-25D is able to control the evaporator fan.
