7 P7 parameter Function: To set drip time for
defrost water to drain out.
P7 To change Use UP/DOWN keys to get
the P7 desired value. This is the time
parameter, for which the fan, compressor,
press the heater will stay off so that the
SET key. defrost water can drip & drain out.
8 P8 parameter Function: To set compressor
relay status on room probe
failure.
P8 To change Use UP/DOWN keys to set
the P8 desired value.
parameter, When set to
press the 0 = Comp status is ON.
SET key. 1 = Comp performs a duty cycle
10 minutes ON and 4minutes
OFF.
2 = Comp status is OFF.
9 L1 parameter Function: Evap. fan stop temp
(Coil)
L1 To change Use UP/DOWN keys to set
the L1 desired value. This setting
parameter, is used to limit the max

SET key. Evap. fan will cut off.
10 L2 parameter Function: To set time delay
between Evap. fan relay restart
time.
L2 To change Use UP/DOWN keys to set
the L2 desired value. If for example

SET key. set by L1 parameter but the fan
will not come on for a minimum
of 3 minutes even if L4 is
achieved earlier.
11 L3 parameter Function: Evap. Fan operation
when compressor is off.
L3 To change Use UP/DOWN keys to set
the L3 desired value.

SET key. 0 = Evap. fan will stay on during
defrost.
15 E1 parameter Function: To set type of defrost
E1 To change Use UP/DOWN keys to set
the E1 desired value.
parameter, 0 = Heater defrost in which case
press the compressor is off.
SET key. 1 = Hot gas defrost where
compressor is on.
