Operation explanation:
•
If Fd0 = 0 then ignore Fd1/Fd2/Fn1/Fn2/FC1/FC2/FC3 fan stays ON when compressor cycles OFF (disable fan
cycling in all modes)
•
If Fd0 = 1 then fan cycles when compressor cycles OFF according to Fd1/Fd2/Fn1/Fn2/FC1/FC2/FC3
•
If Fd1 = 0 then fan runs continuously during DAY mode when compressor cycles OFF (disable fan cycling during
DAY mode)
•
If Fd2 = 0 then fan runs continuously during DAY Mode when compressor cycles OFF (disable fan cycling during
DAY mode)
•
If Fn1 = 0 then fan runs continuously during NIGHT mode when compressor cycles OFF (disable fan cycling during
NIGHT mode)
•
If Fn2 = 0 then fan runs continuously during NIGHT Mode when compressor cycles OFF (disable fan cycling during
NIGHT mode)
•
Normal Mode
•
DAY
•
If FC1 = 1, then cycle fan as regulated by Fd1 and Fd2
•
NIGHT
•
If FC1 = 1, then cycle fan as regulated by Fn1 and Fn2
•
ECO mode
•
If FC2 = 1, then follow Normal Mode fan cycling
•
SUPERFROST Mode
•
If FC3 = 1, then follow Normal Mode fan cycling
•
DOOR Open
•
If Fd=1, then SWITCH OFF fan, respecting item “d4”.
•
DEFROST
•
FAN:
ON
•
IF Regulation Probe Reading > FH, then Suspend any Fan Duty Cycle (Fan is always ON) until reading < (FH – FHd)
8.12 WINTER MODE
Parameter Description
Units
Min
Max
Ht
Enable winter mode (heater control mode)
NO / YES
HAt
Heater activation temperature threshold (using the regulation probe)
°C
-50
90
HAd
Heater activation delay
Min
0
255
HdF
Heater activation temperature differential
°C
0
25
Note: Maximum value of HAt should be less than the SUPERFROST set point value, this is to prevent unpleasant
compressor operation whereby both compressor and heater may come ON at the same time when the
temperature drops below HAt for more than HAd. We have overcome this by keeping the compressor OFF when
the winter mode (heater mode) is activated (in operation). This will give you more in setting HAt value.
Operation explanation:
•
If regulation probe reading <HAt for more than HAd
•
Compressor:
OFF OK
•
Heater:
ON
