FRESH AIR REHEATING SET POINT Function Climatic may be set to maintain a comfortable blowing temperature, by compensating the cold contribution of fresh air in winter. Description If this function is activated: • If the room temperature is in regulation dead zone, or heating mode, the blowing air regulation rule will maintain a blowing temperature at least equivalent to the heating threshold. • If the room temperature is in cooling mode, the minimum blowing temperature will be equal to the safety low limit threshold plus 2K. 3331 � Activation of the control of reheating of the fresh air, adjustment per zone. HUMIDITY SET POINT (option) Function The relative humidity of room is maintained between two thresholds, a minimum threshold corresponding to the point of humidification and a maximum threshold corresponding to the point of dehumidification. Description Dehumidification It is ensured by the compressors in cooling mode. It is active in the dead zone and cold mode of room temperature control. Climatic gives priority to the temperature. To ensure a complement of heating, the fresh air reheating set point must be activated. Humidification A signal 0-10v is generated proportionally to the regulation request. 3341 � Dehumidification threshold - Relative humidity (%hr), adjustment by zone. 3342 � Humidification threshold - Relative humidity (%Hr), adjustment by zone. 3358 � Activation or inhibition, humidity control.

THERMOSTAT / HYGROSTAT – Control principle Function Adjust and hold the room air temperature or humidity as close as possible to the set point, by controlling the number of compressor stages depending on the thermal load of the system. Description CLIMATICTM50 control constantly calculates the required capacity to reach the temperature set point. This variable is called “CAPACITY FACTOR” (CF) and its value can vary from 0 to 100%. It is directly linked to the number of control stages of the unit. Thus for a unit with 4 stages of regulation, the CF will start and stop a stage with the following values: 0-25-50-75-100. It then evolves following the principles detailed in the diagram below (case of a cooler): + 2°K + 1°K Difference between the Room Temperature and the 0°K set point - 1°K - 2°K CF FROZEN CF DECREASES (Removes Capacity Stages) In order to anticipate, the reference point is recalculated each time the difference between air temperature and set point reach a minimum or a maximum. The rate of change of the Capacity Factor (CF) is determined by another parameter called “REACTIVTY” and which value is in: % of CF / °C (Diff vs Set point) / min 3361 � REACTIVITY for the cooling mode. 3362 � REACTIVITY for the heating mode. 3363 � REACTIVITY for the fresh air reheating mode For the option of control humidity 3364 � REACTIVITY for the dehumidification mode. 3365 � REACTIVITY for the humidification mode. CF INCREASES (Start more Capacity Stages) CF FROZEN FAST SLOW Room Temperature Change rate SLOW FAST Permutation, Cold or Heat Mode (Change-Over ; optional) The choice of the operating mode in cooling or heating is automatically carried out according to the room temperature and the temperature set points adjustment. Meanwhile as an option, using free contacts on parametric inputs, it is possible to disable one mode or another. (see Customized Input / Output (BE.50)) • With a free contact on [Sw Dis.Cool] The contact closing will disable the cooling mode. • With a free contact on [Sw Dis.Heat] The contact closing will disable the heating mode.
