IB-Therm 203 room thermostat is designed
to control valves, air dampers and heaters, fan
coils and other heating appliances. IB-Therm
203 thermostat allows to control process of
heating, cooling and ventilation comfortably
in the each type of buildings. It allows to save
energy costs, contributing to protect our
environment.

1x Operating manualʛ
Thermostat measures the temperature by
built-in sensor. The knob is used to set the
desired temperature (switching threshold).
In the heating mode output device is turned
on when the real temperature is lower than
the desired temperature.
In the cooling mode output device is turned
on when the real temperature is higher than
the desired temperature.
Ventilation speed switch allows to set venti-
lation’s eciency (fan coil gear, fan gear).

Thermostats powered from 230V mains vol-
tage are delivered implicitly. Also thermo-
stats powered from 24V voltage source can
be delivered (the same model for AC and DC
voltage) if ordered. If you want to buy 24V
thermostat, please indicate it in the order.

Changing between heating and co-
Ioling modes only inverts the logical
process. Outputs for connecting the
output device are the same (3 - pro-
cess is being performed, 4 - process is
not being performed) for heating and
cooling. Independent outputs for he-
ating and cooling are implemented in
IB-Therm 203S thermostat for four-pi-
pes fan coils.

In this example, IB-Therm 203 thermo-
stat controls the two-pipes fan coil. Fan coil
function (cooling or heating) is determined
in advance and the same operational mode
(heating or cooling) must be selected in the
thermostat.
In the heating mode:
When the thermostat is turned on and the
real temperature is lower than the desired
temperature, a valve is open (230V phase is
in the yellow wire) and fan works at chosen
speed.
When the thermostat is turned o or the real
temperature is higher than the desired tem-
perature, a valve is closed (230V phase is in
the red wire) and fan is turned o.
In the cooling mode:
When the thermostat is turned on and the
real temperature is higher than the desired
temperature, a valve is open ( phase is in the
yellow wire) and fan works at chosen speed.
When the thermostat is turned o or the real
temperature is lower than the desired tem-
perature, a valve is closed (phase is in the red
wire) and fan is turned o.
