Table 13: Defrost parameters
* G17 parameter >> Three defrost modes are available:
▪ G17 = EL → Defrost through electrical heater
▪ 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 time clock), 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, On during defrost
▪ G42 = Oy (3) →Fans will run continuously also during defrost
Manual defrost
Please check settings for evaporator fans. The XCM25D controller is able to control the evaporator
fan.
NOTE: For additional features please contact your local Application Engineering
representative.

CAUTION
Low refrigerant charge! Compressor damage! Never energize the
unit/controller without minimum refrigerant system charge. There is a risk of
malfunction of the controller in deep vacuum operation which can cause
compressor damage.
