203GT
Heating
regulator
203GT is a new generation heating regulator.
Its versatility, intelligence and clarity have made it
an ideal heating regulator for all kinds of water
circulation heating systems.
In addition to heating control, 203GT has a
number of other control and alarm functions
for facilities.
Measurement information can be read, settings
and controls can be checked and adjusted,
and alarms can be received and acknowledged
remotely via a GSM telephone’s text messages.
A GSM modem (optional equipment) must be
connected to 203GT to enable GSM use.

The basis for an even room temperature is a characteristic heating
curve of just the right shape. The right shape for a characteristic
heating curve depends on many factors.
In 203GT the characteristic heating curve can be
adapted to exactly meet the needs of the facility from three points;
203GT prevents the setting of an incorrectly shaped charac-
teristic heating curve. It automatically suggests an adjustment.

CURVE INTERPRETATION:
When the outdoor temp. is:
-20 C, the supply water is +32 C
0 C, the supply water is +27 C
+20 C, the supply water is +21 C
The temperature of the supply water may vary from the curve
if a reduced operation mode, room, wind or sun compensation
has been connected to the regulator or if one of the limiting functions
limits the temperature (see p. 11).
If the outdoor sensor is disconnected or if the sensor is broken,
the regulator assumes that the outdoor temperature is 0 C (use during
construction without the outdoor sensor).

EXAMPLES OF DIFFERENT HEATING SYSTEMS:
a) Floor heating
If the room temperature drops in subzero weather, raise the curve setting at -20 C.
If the room temperature rises in subzero weather, lower the curve setting at -20 C.
If the room temp. feels chilly at zero degree weather, raise the curve setting at 0 C.
In this way you can set the regulating curve to meet the heating needs of your facility.

Houses with floor heating
Set the 203GT regulator's maximum limit between +35 ... +40 C and the
minimum limit between +20 ... +25 C.
In floor heating solutions it is important to make sure that exessively hot
water which could damage structures or surfaces doesn't ever get into the
network. A mechanical thermostat should be installed on a supply water
pipe which stops the circulation pump in case of overheating. Ouman Oy
keeps CO1A surface mounted thermostats in stock that are suitable for this
purpose. Set the thermostat at 40 ... 45 C.

.
The supply water temperature drop,
determined by the clock program or the
external home/away switch. (Room
compensation takes a desired drop in room
temperature into account)
Minimum allowed supply water temperature.
Set the minimum limit for floor heating circuit
tiled floors between 20...25°C, to ensure a
comfortable temperature and removal of
moisture in the summer.
Maximum allowed supply water temperature.
The maximum limit prevents the temperature
in the heating circuit from rising too high,
preventing damage to pipes and surface
materials. If, e.g., the characteristic heating
curve setting is incorrect, the maximum limit
prevents excessively hot water from entering
the network. Set the upper limit for floor
heating between 35...40°C.

The automatic pre-increase in degrees which
occurs after a reduced operation (nighttime drop)
The pre-increase makes it possible to raise the
room temperature faster to a nominal room
temperature (day temp.) after a reduced
operation. A maintenance person must set the
length of the pre-increase time (see maintenance
mode p 21).
In autumn, the temperature of the supply water is
automatically raised for 20 days through autumn
drying. Autumn drying is activated when the
average temperature in a 24-hour period has
continually been above 7 °C for a period of at
least 20 days and after this drops below 7 °C.
Autumn drying is activated during the next 20
days whenever the average temperature in a 24-
hour period is under 7 °C. The autumn drying
setting indicates how much autumn drying raises
the supply water temperature. The original factory
setting is 1 °C.

Valve closed during the summer: The outdoor
temperature limit at which the regulator closes the
valve in H1 circuit. Circuit 2 is often used to warm
up the wet places (sauna stove, lavatory and so on)
Because it is important to warm up the wet places
also summer time, the valve in circuit 2 is not closed.
Room compens. Room compensation ratio: If the room
temperature is different than what it is set at,
the room compensation corrects the supply
water temperature. (Eg.) If the room
compensation is 4 and the room temperature
has risen 1,5 above the setting, the regulator
drops the supply water temperature 6
(4x1,5 =6 ).

A house cools down in windy weather. In that

maximum amount that the wind compensation
can raise the supply water temperature.
The room temperature of a house having large
