Table 3--5 Controller Function Codes (Sheet 4 of 4)
Cd47 Variable Economy
Temperature Setting
Code Cd47 is used with optional economy mode. The values are 0.5C-4.0C. The
default is 3.0C. If the unit is not configured for economy mode, “----” will be dis-
played.
Cd48 Dehumidification Pa-
rameter Selection
Code Cd48 is used both when dehumidification set point is set above 65% RH
and below 64% RH. When dehumidification set point is set above 65% RH, select
goes to LO if it had been set to hi. When dehumidification set point is set below
64% RH, select goes to Alt if it had been set to LO.
Cd49 Days Since Last
Successful Pre-trip
Code Cd49 will display the time period (days) since the last successful pre-trip.
Cd51
Automatic Cold
Treatment
Parameter Selection
Code Cd51 initially displays countdown timer increments of 1 day, 1 hour with the
temperature default. Pressing ENTER allows selection of within the current menu
and proceeds to the next menu. After five seconds of no activity, the display re-
verts to normal system display, but retains the parameters previously selected.
“ACt” = “On,” “Off” or “----”. The default is Off.
“trEAt”=C /F in 0.1 degree increments. The default is 0.0C.
“DAyS”= “0-99” increments of 1. The default is 0.
“ProbE”=probe positions (example 12_4) . The default is ----.
“SPnEW”= C /F in 0.1 degree increments. The default is 10.0C.
Cd53
Automatic Set point
Change Mode
Parameter Selection
Code Cd53 initially displays countdown timer increments of 1 day, 1 hour with the
temperature default. Pressing ENTER allows selection of within the current menu
and proceeds to the next menu. After five seconds of no activity, the display re-
verts to normal system display, but retains the parameters previously selected.
“ASC”=“On” or “Off” The default is Off.
“NSC”=“1-2”
“SP 0”=C /F in 0.1 degree increments. The default is 10.0C.
“DAY 0”= “0-99” increments of 1. The default is 1.
“SP 1”=C /F in 0.1 degree increments. The default is 10.0C.
“DAY 1”= “0-99” increments of 1. The default is 1.
“SP 2”=C /F in 0.1 degree increments. The default is 10.0C.
Cd54 Suction Superheat
Code Cd54 will display the suction superheat values in C /F as calculated by the
suction temperature minus the suction saturation temperature as calculated from
suction pressure. “-----” will be displayed if the selection is not valid.
Cd55 Discharge Super-
heat
Code Cd55 will display the discharge superheat values in C /F as calculated by
the discharge temperature minus the discharge saturation temperature as calcu-
lated from discharge pressure. “-----” will be displayed if the selection is not valid.
