17. OUTSIDE COMPENSATION OF TEMPERATURE
Compensation functions are only enabled if the outside detector B2 is connected. Such functions
can be as follows:
• Compensation of desired flow Heating and Cooling temperatures;
• Summer compensation of desired room or flow Cooling temperatures;
Desired temperature adjustment values,
Resulting from compensation, are displayed in
and
17.
1
Climatic compensation of desired flow Heating and Cooling temperatures
This function can be only used if detectors B1 and B2 are connected, and Detector B3 is not
connected. It is useful when the primary air system, in addition to ensuring air circulation, is also
intended to make up for ambient dispersion.
Desired flow Heating temperature
The controller increases desired temp. when outside temperature drops,
according to settings:
• Heating Comp. : NO = function disabled
YES = function enabled
• Opt

c = default outside temp. : winter
• Fpt
: xx
c = default flow temp. : winter
Desired flow Cooling temperature
The controller decreases desired temp. when outside temperature
increases, according to settings:
• Heating Comp. : NO = function disabled
YES = function enabled
• Opt : xx
c = default outside temp. : summer
• Fpt
: xx
c = default flow temp. : summer
17.
2
Summer compensation of desired room Cooling temperature
This function can be only used if detectors B2 and B3 or B1, B2 and B3 are connected. It is useful to
prevent excessive temp. differences between room and outside.
The controller maintains temp. at a constant level
until outside temp. exceeds the value
