Warning

Device is constructed for connection in
1-phase main alternating current voltage AC
230V or 24V 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, connection, 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
overvoltagepeaksanddisturbanciesin 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 ensure 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.

- 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 temperature sensors and associated
function)
- time program - switches or sets required temperature according
to set time program
- 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 - CZ / SK / EN / RO / PL / HU / RU (factory
setting EN).

- Output 15-18 is closed, if temperature of both

thermostat reaches adjusted level, the contact 15-18
open. Serial inner connection of thermostats (logic
function AND).
- Switching of output corresponds with input, which
has lower temperature when di ference is exceeded
di erencial thermostat 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.

- 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 auxi-
liary. 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 erence (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 asT1-D.The function is
used for protection of gutters against freezing.

- In case of thermostat with a„dead zone“ , it is
possible to set temperature T1 and a di erence
(respectively a width of dead zone D). If temperature
is higher than T1, output contact of cooling switches
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.
