Cellar Construction

This is only a guide and shall be considered as minimum requirements.

All interior walls and floors shall have a vapor barrier and a minimum of R13

insulation. All exterior walls and ceiling shall have a vapor barrier and a minimum

of R19 insulation. The vapor barrier shall be installed on the warm side of the

insulation. All joints, door frames, electrical outlets or switches and any pipes or

vents that go through the cellar shall be sealed to prevent air and moisture

leakage into the cellar. Concrete, rock, and brick are not insulation or vapor

barriers.

Doors shall be of a minimum size, insulated to at least R13 and tightly sealed

with high quality weather stripping. Be sure to seal the bottom of the door and fill

gap between the door’s frame and wall before installing the cap molding.

In order to maintain 55 °F in the wine cellar, the ambient temperature

surrounding the enclosure shall not exceed the temperature of the cellar by more

than 25 °F. No cellar wall shall receive direct sun or strong wind.

Lighting shall be of low wattage, with a timer to insure lights are not left on when

the cellar is not occupied.

The cooling system will not be able to maintain the proper temperature if fresh

moisture-laden air is constantly being introduced to the cellar. Symptoms of this

condition are; cooling unit runs all the time with only a slight reduction in

temperature and/or water overflows from the unit. Because of the temperature

difference between the inside and outside, very small cracks can allow large

amounts of outside air to enter into the cellar. Please be aware that moisture can

pass through solid concrete, paint and wood. Often a newly constructed cellar

contains fresh wood, paint, concrete and other building materials. These

materials contain large amounts of moisture. When placed into operation in this

type of environment, the system will work harder to remove this extra moisture

resulting in increased “run” time.

Features and Specifications

•Wine-Mate rack split cooling systems WM-2500~6500SSRWC are designed

and used to provide a cold temperature between 50~65 °F for a properly

insulated wine cellar.

•The wine cellar will maintain humidity range within 50~70% RH.

•These temperature and humidity ranges like in natural caves are optimized

for long term storage of wine.

•SSRWC units consist of a condensing unit and an evaporator unit; they are

connected by a liquid line and an insulated suction line.

•SSRWC condensing units can be located away from the evaporator unit 50 ft

so that noise and compressor vibration are isolated.

•SSRWC condensing units are water cooled so that exhaust ventilation is not

needed.

•SSRWC evaporator units are designed for installation inside a rack or

between two ceiling joists, making them an ideal choice for small and medium

wine cellars. There are also multiple air inlet and outlet doors for different

installations.

Fig. 1 SSRWC Rack Split Cooling System

NOTE:

Capacity is determined under the cellar, the cellar ambient and the

condenser inlet water temperatures of 55°F, 75°F and 75°F, with R13

interior and R19 exterior insulations. Any higher ambient and water

temperatures, lower insulations will cause reducing capacity and the cellar

temperature may not be maintained at 55°F.

Temperature and Humidity

1. Use of the controller

Fig. 2 Temperature Controller

1) Keys

SET: To display target set point; in programming mode it selects a parameter or

confirm an operation.

(DEF): To start a manual defrost.

(UP): To see the maximum stored temperature; in programming mode it

browses the parameter codes or increases the displayed value.

(DOWN): To see the minimum stored temperature; in programming mode it

browses the parameter codes or decreases the displayed value.

: To turn on/off the power to the unit.

+: To lock/unlock the keypad.

SET+ : To enter in the programming mode.

SET+ : To return to the temperature display.

2) Lock and unlock the keys

To lock the keys, press up + down keys +until POF is displayed; to unlock

the keys, press up + down keys +until PON is displayed.

3) Display

During normal operating conditions, the display shows the value measured by

the air regulation probe. In case of active alarm, the temperature flashes

alternately to the code alarm. The LED functions are listed as follows.

LED MODE FUNCTION

ON Compressor enabled

Flashing Anti-short cycle enabled

ON Defrost cycle enabled

ON Fan enabled

Flashing Fan delay after defrost enabled

ON Alarm occurring

ON Temperature measuring unit

Flashing Programming mode

4) Alarm Signals

The alarm codes are described as follows.

MESSAGE CAUSE FUNCTION

P1 Temperature probe faulty Compressor switching to Con and CoF

HA High temperature alarm Probe temperature ALU higher than the

setting temperature; Outputs unchanged

LA Low temperature alarm Probe temperature ALL lower than the

setting temperature; Outputs unchanged

CA External alarm All outputs off

Probe alarms P1”, start a few seconds after the fault in the related probe; they

automatically stop a few seconds after the probe restarts normal operation.

Check connections before replacing the probe. Temperature alarms “HA”, “LA”

automatically stops as soon as the temperature returns to normal value. Alarm

“CA” (with i1F=PAL) recovers only by switching off and on the instrument.

2. Temperature Setting

•Set the temperature at 55 °F for the optimum aging of wine

•On initial start-up, the time required to reach the desired temperature will

vary, depending on the quantity of bottles, temperature setting and

surrounding temperature.

•Allow 24 hours to stabilize the temperature for each new temperature setting

operation

3. How to see temperature set-point

1) Press and immediately release the SET key, the display will show the set-point

value.

2) Press again and immediately release the SET key or wait for 5 seconds to

display the probe value.

4. How to change the set-point

1) Press the SET key for more than 3 seconds until the “°C” or “°F” LED starts

blinking and the set-point will be displayed.

2) To change the set value, press the up/down keys /within 10 sec.

3) To store the new set-point value, press the SET key again or wait 10 sec.

NOTE: The unit turns on at set-point Set plus regulation differential Hy after anti-

short cycle AC has elapsed; the unit turns off at set-point Set.

5. How to calibrate the air temperature probe

If the actual cellar temperature differs from the displaying temperature, set ot =

actual cellar temperature minus displaying temperature.

6. How to adjust defrost cycle

1) In case there is excessive frost, the parameters FnC =C-y, idF =6 and MdF =

20 can be used to avoid defrost.

2) In case the air probe is located in the return duct, the parameters FnC =O-n,

idF =8 and MdF =20 can be used to help drain.

7. How to adjust the humidity

The parameter Fon is used to adjust the humidity in the wine cellar. Higher Fon

results in higher relative humidity. Use a separate hygrometer to monitor the

humidity.

8. How to set alarm call

1) Speech notice will be sent to your phones when the cellar temperature is ALU

higher or ALL lower than the set-point Set.

2) In order to test the call function, set parameters Ald = 0 and dAO = 0. After

testing, set Ald = 60 and dAO = 23.

9. How to set low cellar temperature heater

The heater turns on at set-point SAA minus regulation differential Shy; the

heater turns off at heater set-point SAA.

NOTES:

•Use a forced air heater to warm up the wine cellar.

•If there is a thermostat on the heater, bypass it or set the thermostat at the

highest level.

•If the heater runs more than 10 A current, use a 120VAC coil contactor.

10. Manual Defrost

Press the DEF key for more than 2 seconds and a manual defrost will start.

11. Parameter Programming

1) Press the SET +keys for more than 3 sec until the “°C” or “°F” LED starts

blinking, then release the keys.

2) Press again the SET +keys for more than 7sec until the Pr2 label will be

displayed, then release the keys. The first parameter Hy will be displayed.

- 9 -

3) Press up/down keys /to scroll to the required parameter within 10 sec.

4) Press the “SET” key to display its value.

5) Use up/down keys to change its value within 10 sec.

6) Press “SET” to store the new value.

7) To exit: Press SET + or wait 15sec without pressing a key.
