Introduction
Congratulations! You have purchased a new IWARM heat
management system.
The IWARM 730 thermostat series have inherent fea
tures that are highly reliable, easy adjustment, simple display
and modern design.
IWARM 730 will make the heating in your home more
efficient, most comfortable, easy and convenient at use.

Functional description
IWARM 730 thermostat is designed to manage
"Warmfloor" (heating mats or cable sections) electrical heat
ing systems for two separate areas. The device automatically
maintains the comfortable temperature set by you, using the
readings of floor temperature sensors (included); these sen
sors are located in two various heating zones (in two areas).
Floor temperature (actual and set by you) is indicated on the
display.
IWARM 730 performs selfdiagnosis. In the event floor
temperature sensor has a malfunction, it will display a warn
ing messages (see page 11 for details). In this case the
device may work in socalled "service mode" of heat man
agement (see page 12 for details).

Controls and display (fig.1)
1. Symbol for heating system switched on mode.
2. Chosen heating zone No. display.
3. Current floor temperature in the chosen zone (°С).
4. Set temperature (°С) in the chosen zone.
5. "+"key for temperature increase.
6. "–"key for temperature decrease.
7. Key to shift the heating zones.
When the heating is on, a symbol for heating system
switched on mode appears on the screen. When the heating
is switched off the symbol disappears.
Capital figures show the actual current floor temperature
of the chosen zone (position 3); figures in top right show the
set floor temperature in this zone (position 4).
The set temperature may be changed by pressing "+" key
to increase (position 5), and "–" key for decrease (posi
tion 6).

Pressing the ZONE/AAkey (position 7) once will shift the
heating zone in order to manage temperature settings in each
zone.

Managing and operating
Switching thermostat on/off (Automatic Mode)
To switch the thermostat on/off you should press and hold
the central key (ZONE/AA) for not less than 3 sec. The device
goes into the main display mode (fig. 2).
Blocking and Deblocking
The device is equipped with key blocking to protect it from
children and accidental pressing. The blocking switches on
automatically in 40 sec. after the last pressing of any key; the
display highlight dims.

In order to deblock the device, you should press and
hold simultaneously "+" and "–" keys for not less than
3 sec. After it the blocking mode is switched off, and the
display lights up.
Alternating the heating zones (Fig. 3)
In order to alternate between the heating zones (heated
areas) you should press the central key (ZONE/AA). At this
time the zone symbol will change (fig. 3). Capital figures show
the actual current floor temperature in the chosen zone

(area), small figures at top right show the temperature set in
this zone.
Temperature adjustment
Choose area by pressing ZONE/AA. Enter the required
temperature using "+"/"–" keys.
Now the system will maintain the set temperature auto
matically by heating up the floor and switching off when the
set temperature is reached. Thus energy saving system
usage is performed.
Switching one of the heating zones off
In order to switch off the heating in one of the areas you
should set minimum temperature in this area, i.e. +5ОС.
