16. 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 tem-
peratures;
• Summer compensation of desired room or flow Cooling
temperatures;

Compensation of desired flow Heating and Cooling temperatures
This function can only be 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 : xx 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

Operating modes
The controller can operate in the following modes:
– ON Winter; OFF Winter
– ON Summer; OFF Summer
– ON; OFF
depending on :
– current season according to setting in
(see paragraph 24).
– status of season switching
(
ss)
and/or the control
c1
(terminals D-E1-E2).
Examples :
• With
mode is : ON
– when contact c1 (D-E1) is closed
OFF
– when contact c1 (D-E1) is open
• With
mode is : ON winter – when contact c1 (D-E1) is closed
OFF winter – when contact c1 (D-E1) is open
• With
mode is : ON Summer – when contact c1 (D-E1) is closed
OFF Summer – when contact c1 (D-E1) is open
• With
with ss contact on Winter (D-E1 closed)
mode is : ON Winter - when contact c1 (D-E1) is closed
OFF Winter - when contact c1 (D-E1) is open
• With
with ss contact on Summer (D-E2 closed)
mode is : ON Summer - when contact c1 (D-E2) is closed
OFF Summer - when contact c1 (D-E1) is open
