- digital thermostat with 6 functions and built-in time switch clock with day, week
and year program. You can also limit temperature functions and courses this way
in real time.
- the temperature prole can be changed using the time program.
- complex home and water heating, solar heating, etc.
- two thermostats in one, two temperature inputs, two outputs with dry contact.
- maximum universal and variable thermostat including all ordinary thermostat
functions.
- functions: two independent thermostats, dependent thermostat, dierential ther-
mostat, two level thermostat, zone-based thermostat, dead zone thermostat.
- monitoring function for short circuit or sensor disconnection.
- program setting of output functions, calibration of sensors according to reference
temperature (oset).
- the thermostat is subject to the digital clock programs.
- wide range for setting control temperature - 40 to 110°C.
- clear display of set and measured data on a backlit LCD.
- Switching modes:
- Auto – automatic switching mode:
- Programme – switching based on a programme (astro or time).
- Random – switches randomly in a 10–120 minute interval.
- Holiday – holiday mode – option of setting up a period for which the timer will
be blocked, i.e. will not switch based on the set programmes.
- Manual – manual mode – option of controlling the individual output relays
manually.
- Options of the automatic switching programme:
- ter - switches according to set thermostat function (switches based on tempera-
ture sensors and associated function).
- time program - switches or sets required temperature according to set time pro-
gram.
- 100 memory locations for time programs (common for both channels).
- Programming can be performed under voltage and in backup mode.
- The relay outputs do not work in backup mode (battery-powered).
- Choice of menu display - EN / CZ / RU / HU / ES / PL / SK (factory setting EN).
- Choice of automatic daylight savings time transition according to time zone.
- Backlit LCD display.
- Easy and quick setting with the help of 4 control buttons.
- Pluggable transparent cover on front panel.
- The time switch clock has a battery backup, which retains data in case of a power
outage (reserve backup time - up to 3 years).
- Power supply: AC 230V or 24V AC/DC (based on type of device).
- 2-module, DIN rail mounted.

CONTROL OF A DISPLAY WITH BACKLIGHT
Power on: Display is illuminated with a
backlight for 10 seconds from the last but-
ton press. The display continuously shows
the settings – date, time, day of the week,
contact state and programme. Permanent
on / o is activated by simultaneous press-
es of the MAN, ESC, OK buttons.

low an adjusted level. When any thermostat reaches adjusted lev-
el, the contact 15-18 open. Serial inner connection of thermostats
(logic function AND).

Typical example of use for two-stage thermostat is e.g in boiler-
room, where there are two biolers from which one is main and the
other one is auxiliary. The main boiler is managed according to set
temperature and auxiliary boiler is switched in case temperature
falls under set dierence. Thus it helps to the main boiler in case
outside temperature dramatically falls. In the range of set dier-
ence (D) output 15-18 functions as normal thermostat to input 1
(type 1). In case temperature falls under set dierence, output 2
switches.
Output is closed (heating) only if temperature is within adjusted
range.If temperature is out of range, the contact opens. T is set as
T1-D. The function is used for protection of gutters against freez-
ing.
Legend:
Ts1 - real (measured) temperature T1
Ts2 - real (measured) temperature T2
D - adjusted dierence
dy1- set switching delay of the output
dy2 - set delay on output breaking
15-18 output contact (for T1)
25-28 output contact (for T2)
Switching of output corresponds with input, which has lower
temperature when diference is exceeded dierencial thermo-
stat is used for keeping two identical temperature e.g. in heating
systems (boiler and reservoir), solar systems (collector, reservoir
exchanger), water heating (water heater, water distribution)etc.
6. Thermostat with dead zone
Legend:
Ts - real (measured) temperature
T1 - adjusted temperature
T=T1-D
H1 - adjusted hysteresis for T1
H2 - adjusted hysteresis for T
dy1- set switching delay of the output
dy2 - set delay on output breaking
15-18 output contact (heating)
25-28 output contact (cooling)
In case of thermostat with a „dead zone“, it is possible to set tem-
perature T1 and a dierence (respectively a width of dead zone D).
If temperature is higher than T1, output contact of cooling switch-
es ON; if the temperature gets bellow T1, the contact switches
OFF. If the temperature gets bellow temperature T, the contact
of heating switches ON and it switches OFF when temperature T
is exceeded. This function can be used for example for automatic
air warming and cooling in ventilation so the sit is always within
the range T1 and T.

Time correction:
The shift unit is 0.1s per day.
The numeric value refers to seconds per 10 days.
Time correction is factory-set and individual for each product so that the real-time clock would run with minimum deviation. The time correction value can be arbitrarily adjusted, but after product
RESET, the value returns to factory settings.

Performed by shortly pressing the hidden RESET button with a blunt-pointed object (e.g. a pencil
or screw-driver with a diameter of at most 2 mm).
The type of device and software version will be displayed for 1 second, then the device will enter
default mode. This means that the language is set to EN, all data is zeroed (thermostat function,
time/date, user programs, device options function).

An example of TER-9 programming
Battery replacement
You can change the battery without disassembling the device.
CAUTION
- only change the battery when the device is disconnected from power supply !!!
- the date and time must be reset after changing the battery !!!
- remove the plug-in module with the battery
- replace the original battery
- enter a new battery so that its upper edge (+) lines up with the plug-in module
- slide the plug-in module in the device and pay attention to polarity (+ up) – for roughly 1 s,
the display will show the name and the software version
- you can connect the device to power supply
Setting the TER-9 in the function: two dependent thermostats with temperature setting T1 = 10°C a T2 20 °C with hysteresis setting T1 = 2 °C a T2 = 1°C.
With automatic controlled temperature change on 18.11.2010 at 6:52 p.m. to the temperature T1= 15 °C.

Warning

Device is constructed for connection in 1-phase main alternating current voltage AC 230 V or
24 V AC/DC (based on type of device) and must be installed according to norms valid in the
state of application. Connection according to the details in this direction. Installation, con-
nection, setting and servicing should be installed by qualied electrician sta only, who has
learnt these instruction and functions of the device. This device contains protection against
overvoltage peaks and disturbancies in supply. For correct function of the protection of this
device there must be suitable protections of higher degree (A, B, C) installed in front of them.
According to standards elimination of disturbancies must be ensured. Before installation the
main switch must be in position “OFF” and the device should be de-energized. Don´t install
the device to sources of excessive electro-magnetic interference. By correct installation en-
sure ideal air circulation so in case of permanent operation and higher ambient temperature
the maximal operating temperature of the device is not exceeded. For installation and setting
use screw-driver cca 2 mm. The device is fully-electronic - installation should be carried out
according to this fact. Non-problematic function depends also on the way of transportation,
storing and handling. In case of any signs of destruction, deformation, non-function or missing
part, don´t install and claim at your seller it is possible to dismount the device after its lifetime,
recycle, or store in protective dump.
