Recommended Coolants:
Solid State Cooling Systems recommends using Koolance, a pre-
mixed 27% propylene glycol/water based coolant containing an
algaecide and corrosion inhibitors. Though it comes in several
colors, SSCS recommends the colorless or blue versions in 700 ml
bottles, part number: LIQ-702CL-B (clear) or LIQ-702B-B (blue),
as the dyes in the other colored versions can form small particulates
when not well mixed.
Contact Koolance for details:
Koolance USA
2840 West Valley Highway North
Auburn, WA 98001
[phone]
Water or ethylene glycol/water mixtures are also acceptable as
coolants.
Note that algae growth can occur when water is used without at
least 25% propylene or ethylene glycol.

5.2 ADVANCED OPERATION The ThermoCube 200/300/400 controller has three menus: the Status
Menu, the Temperature Input Menu and the Parameter Input Menu.
The Status Menu shows the chiller operating status and current
temperature of fluid leaving the chiller (see figure 5). The Status
Menu also allows input of new coolant temperature set-points when
the cycling feature is off. The Temperature Input Menu allows input
of set point temperatures; soak times, number of cycles if cycling
between two temperatures, and an alarm temperature. The Parameter
Input Menu allows input of the temperature units; the time units for
soak times, the PID parameters and the auto tune function.
The PID parameters have been preset at the factory for most
applications. If, however, temperature control in not sufficiently
accurate or if overshoot is excessive, the PID parameters may be
modified. Unless the user is well versed in PID theory, we
recommend calling Solid State Cooling Systems technical support
group for assistance.

5.5 MANUAL TUNING For users well versed in PID theory, Solid State Cooling Systems
recommends the closed-loop “Ziegler Nichols” method for manually
tuning the controller. The method consists of three steps:
1) Turn off both the integral and derivative terms for heating and
cooling by setting I1, I2, D1, and D2 to zero.
2) Set proportional band to 50 °C. Begin controlling the process at
the desired set-point temperature. Look for a small-sustained
oscillation in the coolant temperature. Observe the status menu
operating mode character and note if system is heating (+) or
cooling (-). If no oscillation occurs, lower the proportional band
in 50% increments until a small oscillation occurs. Write down
this proportional band setting (P)
3) Measure the “Natural Frequency” (t) of the system in seconds.
This is the time required for the temperature oscillation to cycle
from one maximum temperature to the next maximum
temperature.
Now set the controller input parameters as follows:
P1 HEAT = 2*P if system was heating in step 2.
P1 HEAT = 4*P if system was cooling in step 2.
I1 HEAT = 1.2*t
D1 HEAT = t/8
P2 COOL = P if system was heating in step 2.
P2 COOL = 2*P if system was cooling in step 2.
I2 COOL = 1.2*t
D2 COOL = t/8

5.6DRAIN PROCEDURE
1. Attach a hose the “Process Out” port of the chiller and place the
end of it in a container with at least a 3 liter capacity.
2. Turn the unit on (making sure to hold the drain hose in place)
and run it until air starts to shoot out of the hose.
3. Attach the drain hose to the “Process In” port of the chiller
4. Remove the tank cap and allow the liquid in the chiller’s lines to
drain out.
5. Replace and tighten the tank cap, then remove the drain hose.
6. Dispose of the coolant in a manner consistent with local
regulations.
SECTION 6
SYSTEM ALARMS/TROUBLESHOOTING ________________________________
The ThermoCube 200/300/400 has multiple system alarms that
when triggered will show on the display. When an alarm is
displayed the system will not attempt to heat or cool the coolant.
Alarms:
Tank Level Low: Liquid reservoir level is too low. Unless filling for
the first time, check all outside plumbing lines for leaks. Once all
leaks are sealed, remove the cap and add more coolant until the
alarm disappears.
RTD Open: The temperature sensor has failed or its connector has
come loose. Turn off the chiller and disconnect the AC power cord.
Contact SSCS for a replacement RTD, or for a RMA number to
return the unit for RTD replacement.
Fan Fail: Fan is supplying insufficient air to cool the thermoelectric
heat exchanger. Either the fan has failed or the airflow into or out
of the system is blocked. Check that the side air inlet and outlet
gratings are not blocked. The ThermoCube requires at least 3
inches of clearance around these gratings. If airflow is not blocked,
contact SSCS for a replacement fan, or for a RMA number to return
the unit for fan replacement.
Pump Fail: The liquid heat exchanger plate temperature is either too
hot or too cold, indicating pump failure, a blockage in the external
plumbing lines or operation outside the normal 5°C to 50°C coolant
temperature (without –LT or –HT options). Turn off the
ThermoCube and disconnect the AC power cord. Verify that no
kinks or blockages exist in plumbing line, both outside and inside
the ThermoCube. If no coolant flow blockages exist, contact SSCS
for a replacement pump, or for a RMA number to return the unit for
pump replacement.
WARNING
Read the Coolant MSDS
prior to draining the
chiller
Electrical Shock Hazard:
Always unplug the unit
before removing the cover.
WARNING
Do not attempt to service or
repair the unit beyond the
troubleshooting checks
described in this section
without first contacting

TELEPHONE:[phone] FAX:[phone] WEB:WWW.SSCOOLING.COM VERSION M28
No Display:If the liquid crystal display does not illuminate upon
turning on the ThermoCube, the internal 12 or 24VDC power
supply has failed, the diaphragm pump has failed, or the LCD
display has failed. Contact SSCS for a RMA number to return the
unit for replacement of the power supply, diaphragm pump, or
display.
Temperature Control Poor: If no other alarms are present, poor
temperature control indicates the heat load is too great for the chiller,
the TE cooling/heating engine is not receiving power, the PID
constants have been corrupted or the chiller needs repair. First check
the PID constant values shown section 5.2 match the factory
defaults. If not, change the values to the default values. Otherwise,
contact SSCS for technical support.
Important: The tank level low alarm will automatically reset when
the tank is filled. The RTD, Fan and Pump failure alarms will not
reset until the system power is turned off.
