The S203 enables control of two different supply water circuits in-
dependently (H1 and H2).
Regulation of the temperature of supply water is controlled by
the outside temperature. Use of room temperature measurements
keeps room temperature more consistent.
3 Regulation of supply water in heating circuits
3.1 Info
The info shows which factors are affecting currently the supply
water temperature control. The starting point is the supply water
temperature according to the outdoor temperature (according to
the heating curve).
If a room sensor is connected to the controller, you can check which
factors currently determine the room temperature setting value
at the time of inspection.
In addition the info menu contains the measurement temperature
data affecting to supply water control and information of control
of actuators.

Factors effecting the supply water temp. Explanation
According to curve
Supply water temperature setting according to the curve at the current outdoor
temperature.
Effect of parallel shift
Effect of parallel shift on the supply water temperature.
Effect of time program
Effect of weekly or exception schedule mode on the temperature of supply water.
Near the end of the temperature reduction time, the pre-increase operation can in-
crease the temperature of supply water.
Force control effect
Supply water has been forced permanently to the desired temperature reduction
level (see Control mode selection).
Away -control effect
”Away” control for reduction of supply water temperature. The trigger can come
from the Home/Away switch, the controller or be sent as a text message (see 41).
Outdoor temp. delay effect
The effect of the outdoor temperature delay on the supply water temperature.
Floor heat. anticipate
Effect of anticipation of floor heating on the temperature of supply water.
Effect of autumn drying
Effect of automatic autumn drying on the supply water temperature.
Return water compensation
Increase in supply water temperature due to return water compensation.
Effect of room compensation
Effect of room compensation on the supply water.
Room comp. time adjustment
Additional correction for more precise room compensation based on realised regu-
lation (effect of I-regulation).
Bus compensation effect
The amount of required compensation is determined by an external device to the
S203, for example from bus compensation to weather compensation.
Min limit effect
Supply water temperature increase due to the minimum limit.
Max limit effect
Supply water temperature drop due to the maximum limit.
Calculated supply water setting
Current supply water temperature determined by the controller.
Controller is stopped for summer
When the regulator is in summer function mode, the supply water information says
”Controller is stopped for summer.”
Controller is in manual control
Control circuit mode is set to ” Manual control”.
