Given the environmental temperature and the humidity, the Touch Screen remote control calculates the dew point. 

In operation of the plant in summer mode, with the double set-point  function active on chillers and thermoregulation normally 

made with the radiant panels (second set of work), it activates a control to keep the dew point of at least a quantity defined by the 

keyboard maintainer parameter 

Par42/65: 

"Dew-point temp. margin

 " °C below the ambient temperature detected by the control 

itself. 

Instead, when 

ambient temperature

 < 

Dew Point + Margin temp. Point

 

The fan coils for dehumidification turn on. 

 

The chiller start working with the set-point for the fan coils. 

The permanence remains in this status until the temperature returns to: 

Ambient temperature 

≥ 

Dew point + Dew temp.  1°C. 

Even in the case where the above condition is verified, it remains in the status  of dehumidification for at least the time set by 

maintainer parameter 

Par43/65: 

"Min. staying time in dehumidification

"

, in order to avoid annoying oscillations. 

If the above condition is not satisfied after a maximum time given by the maintainer parameter 

Par44/65

: "

Max Dehumidification 

time

", the machine comes out from dehumidification. To avoid returning immediately, in this case it requires a minimum staying in 

adjustment to the radiant panels, still given by 

Par43/65: 

"Max. staying time in dehumidification".

CLIMATIC COMPENSATION 

It is possible to compensate the set-point according to outdoor temperature, in a different way between heating and cooling modes, 

first and second set-point. 

In such a case be sure that the 

b08

 parameter 

(System main page -> Configuration -> Service menu -> Parameters -> Chiller -> Chiller 

name -> 

b08:

 

Enab. dynamic set point)

 is disabled (=0) on the chiller.
