Simple operation
Heat source
Temperature sensor

/
This function adjusts the fluid temperature
to the set value with an automatic offset
setting. Set the external temperature
sensor at the circulating fluid inlet located
just in front of the heat source, which
allows the thermo-con to sample the fluid
temperature. This function is effective
when automatically adjusting for heat
exhaust from piping etc.
Less vibration and noise
with no moving parts such
as a compressor. For HECR
004/006/008/010, noise is
reduced by suppressing the
number of fan rotations
when the cooling load is
low.
If the external temperature sensor is installed directly on the heat source, the learning control
function may not work property due to large heat volume or large temperature difference. Be sure
to install the sensor at the circulating fluid inlet.
Circulating fluid volume can be checked.
qTurn the power ON.
wPress the SEL key, and adjust the temperature
setting with the keys.
ePress the RET key to complete.
Can precisely control the temperature of a heat source or process fluid.
Precisely control the temperature of the circulating fluid by using the Peltier device.
Refrigerant-free and environmentally friendly.

Example of circulating fluid piping
Figure 2
The thermo-con is constructed as shown in Figure 1. It
interposes a Peltier device (thermo-module) between the
heat exchangers for the circulating fluid and facility water
and controls the DC power supply to achieve the target
outlet temperature of circulating fluid precisely.
The circulating fluid returns to the tank, and is transferred
by the pump which is built in the thermo-con, and goes
through the heat exchangers and temperature sensor and
out from the circulating fluid outlet.
Figure 2 shows an example of circulating fluid piping. The
circulating fluid is transferred at a constant temperature
by the pump.

Construction and Principles
Principle of Peltier Device (Thermo-module)
A Peltier device (thermo-module) is a plate
type element, inside which P-type semicon-
ductors and N-type semiconductors are lo-
cated alternately. If direct current is supplied
to the Peltier device (thermo-module), heat is
transferred inside the device, and one face
generates heat and increases temperature
while the other face absorbs heat and de-
creases temperature. Therefore, changing
the direction of the current supplied to the
Peltier device (thermo-module) can achieve
heating and cooling operation. This method
has a fast response and can shift quickly be-
tween heating and cooling, so temperature
can be controlled very precisely.

1. How much is the temperature in degrees centigrade for the circulating fluid?
Temperature range which can be set with the thermo-con: 10 to 60 °C
If a lower temperature (down to –20 °C) or higher temperature (up to 90 °C) than this range is necessary, select the
thermo-chiller HRZ series.
Thermo-con/Series HEC
High-precision temperature control type for semi-
conductor manufacturing equipment, medical equip-
ment, etc.
For details, refer to the catalogue on www.smc.eu.
Cooling capacity: 140 W to 1200 W
 Temperature stability: ±0.01 °C to 0.03 °C
Circulating fluids that can be used in the thermo-con: Tap water, Ethylene glycol 20 %
When using fluorinated fluids, select the water-cooled thermo-con HEC series.
2. What kind of the circulating fluids will be used?
Allows a safety factor of 20 % over the capacity that is actually required, taking into account the changes in the operating
conditions. If a larger capacity than this thermo-con is necessary, select the Peltier-type thermo-con HEC series (refer to
the following.) or the refrigerated thermo-chiller HRS/HRZ series.
3. How much cooling capacity required?

Alarm
code Alarm description
Operation
status
Main reason
WRN Upper/Lower temp. limit alarm Continue The temperature has become out of upper/lower limit range for the target temperature.
ERR01 System error 1 Stop The internal cable of the thermo-con has been broken due to abnormal vibration or dropping the product.
ERR02 System error 2 Stop EEPROM data has been lost due to high level noise.
ERR03 Back-up data error Stop EEPROM data of the controller has been destroyed due to high level noise.
ERR11 DC power supply failure Stop The DC power supply has failed (due to fan stop or abnormal high temperature) or the
thermo-module has been short-circuited.
ERR12 Internal temp. sensor high temp. error Stop The internal temperature sensor has become higher than high temp. cutoff setting.
ERR13 Internal temp. sensor low temp. error Stop The internal temperature sensor has become lower than low temp. cutoff setting.
ERR14 Thermostat alarm Stop The thermostat has been activated due to radiator fin clog or fan/pump failure, etc.
ERR15 Abnormal output alarm Continue The temperature cannot be changed even at 100 % output due to overload or disconnection
of the thermo-module.
ERR16 Low flow rate alarm (Option) Stop The flow rate of the circulating fluid has dropped.
ERR17 Internal temp. sensor disconnection alarm Stop The internal temperature sensor has been disconnected or short-circuited.
ERR18
External temp. sensor disconnection alarm Continue The external temperature sensor has been disconnected or short-circuited. (Only detected
when in learning control or external tune control)
ERR19 Abnormal auto tuning alarm Stop Auto tuning has not been completed within 20 minutes.
ERR20 Low fluid level alarm Stop The amount of circulating fluid in the tank has dropped.

Operation Display Panel
This unit is equipped as standard with a function allowing 14 kinds of alarms to display on the LCD and can be read out by serial
communication. Also, it can generate relay output for upper/lower temperature limit alarm and output cutoff alarm.
AT key
Used to start and stop auto tuning.
 key
Used to change set value in each setting
mode.
SEL key
Used to change setting mode.
RET key
Used to fix set value or return to present
temperature status indication.
Maintenance
Please consult SMC for maintenance
Alarm
1st line
Indicates No. corresponding to the alarm
which arises and [WRN] comes to light
up when the upper or lower temperature
limit warning occurs.
4th line
Indicates control operation mode during
normal operation and set values during
setting mode selection.
2nd, 3rd line
Indicates present temperature [PV] and
target temperature [SV] during normal
operation. When the alarm arises, the
error is indicated instead and during set-
ting mode selection, the selected setting
mode is indicated.

Thermo-con/Rack Mount Type Series HECR

With Feet and No Rack Mounting Brackets
With Flow Switch
High Pressure Pump Mounted
Option symbol
Option symbol
Option symbol
Rack mounting brackets and handles on the front side are removed as they are
not necessary when the product is not mounted in a rack. This option has
rubber feet for installing the product on the floor.
This is an ON/OFF switch detecting low levels of the circulating fluid.
When the fluid volume is 1 l/min or less, “ERR16” is displayed and the thermo-con stops.
The flow switch is built into the thermo-con.
Possible to choose a high-pressure pump in accordance with user’s piping resistance.
Cooling capacity will decrease by approx. 20 W (HECR002) or approx. 50 W (HECR004/006/
008/010) by heat generated in the pump.
