Vinotemp WM-45SFCL, WM-65SFCL Dip-switch description See detail in VSTAT instruction, Set Point

Dip-switch description (See detail in VSTAT instruction )

1, 2 differential: added to the Set Point, establishes the temperature threshold, measured by the regulation probe, beyond which the compressor is activated;

3 compressor safety function: OFF - function disabled; ON - function enabled;

4 temperature display: OFF - displayed in °C; ON - displayed in °F;

5,...,8 duration of defrost/defrost termination temperature: if the defrost sensor is utilized, these dip-switches select the defrost termination temperature, otherwise they select the defrost duration;

9 type of defrost: OFF - resistance defrost, ON - hot gas defrost.

1) Set Point

Rotate the circular selector in correspondence with the arrow placed nearby. The selector represents 14°F to 68°F (-10°C to +20°C) for medium temperature models. “10” is the coldest setting, “1” is the warmest. Use the medium temp setting and place the dial at number 3.

2) Differential

It is possible to modify the differential from 1°F minimum to 12.5°F maximum. Simply shift the first two dip-switches to the ON or OFF position according to the wanted value.

3) 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 effective beginning from the successive cycle. For an immediate effect, it is necessary to turn power to the VTSTAT off for a few seconds.

It is possible to choose between an electric defrost (the compressor is deactivated and the defrost relay is activated) and a hot gas defrost (both the compressor and the defrost relay are activated); 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 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 resistance-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.

4) Compressor safety function

If the function is enabled, a minimum three minute interval is ensured between deactivation and successive restart of the compressor.
