WineMate Ducted Wine Cooling System - 1500 Cu. Ft. マニュアル
Differential
It is possible to modify the differential from 1°F minimum to 12.5°F maximum (Fig. 17). Simply shift the first two
dip-switches to the ON or OFF position according to the wanted value.
Defrost management and setting
A defrost can be activated manually, by pressing the “man. def.” button, or cyclically, the interval set by the “def.
intvl” rotary switch at the top left with respect to Set Point selector. The interval can be selected from 1 to 12
hours in 1 hour steps. If the selector is positioned on the “0”, the cyclic defrost is disabled.
Note: manual defrost reinitializes the time required for successive cyclic defrosting. The selections are effecti-
ve beginning from the successive cycle. For an immediate effect, it is necessary to turn power to the UniStat off
for a few seconds.
It is possible to choose between an electric defrost (the compressor is deactivated and the defrost relay is acti-
vated) and a hot gas defrost (both the compressor and the defrost relay are activated); refer to Fig. 20 for the
selection. The defrost termination, can take place by time (from 1 to 60 min.) or by temperature (from 0 to 86°F) if
the defrost sensor is utilized (see Fig. 21 for the correct programming). If the defrost sensor is disconnected,
interrupted or breaks down for any reason, the defrost terminates after a maximum time of 90 minutes if it is resi-
stance-based, or 40 minutes if it is hot-gas based.
The instrument stores the defrost state every 15 minutes to allow restart after power loss.
Compressor safety function
If the function is enabled (Fig. 18), a minimum three minute interval is ensured between deactivation and suc-
cessive restart of the compressor.
If the function is enabled, the compressor is not energized for three minutes after controller power up.
The function is also active in hot-gas defrost mode.
Alarms and signalling
A green LED placed underneath the Set Point selection knob is utilized for signalling the status of the controller:

Set Point
Is set by rotating the circular selector in correspondence with the arrow placed nearby. The selector represents
-33°F to 50°F (-35°C to +10°C) for low temperature models, and 14°F to 68°F (-10°C to +20°C) for medium tempe-
rature models. “10” is the coldest setting, “1” is the warmest. See Fig 24 for appoximate values.
