HUMIDIFICATION
9
9.1 Introduction
The software allows the humidification to be performed by the integrated humidifier installed on the unit.
Activating the humidifying device is enabled only when all the following conditions are met:
•
adjustment consent is active;
•
There is no humidity probe alarm.
•
The humidifier has not been temporarily disabled for maintenance.
•
The humidifier is not performing any water loading/unloading activities.
9.2 Integrated humidifier
In case of built-in humidifier, disabling may also occur in the following cases:
•
following the interruption of communication through the network (RS485 serial), the CPY board stops the KUE unit by
opening the contact. It then waits without producing steam and the "Humidifier Offline" alarm is displayed.
When communication with the external controller is reinstated, the CPY board automatically meets the demand of the
external controller, and the alarm disappears;
•
when the driver M2.4 and M2.5 (enable) contact is opened.
9.2.1
Operating principle
The integrated humidifier belongs to the steam humidifier category, and, in particular, consists of an OEM Carel immersed
electrode humidifier.
Configure the type of humidifier in use under the "Optional" menu that can be accessed with the "Service" password.
INFORMATION:
The relationship between the value of the parameter and the set type of cylinder is described in the
relevant paragraph of the "Annexes" chapter.
The immersed electrode humidifier produces vapour by heating cylinder water to ebullition. Vapour production regulation. Heat
is obtained from the flow of electricity through the water in the cylinder. This procedure is performed by applying voltage to the
electrodes (network) immersed in the water.
At the beginning, when the cylinder is new or freshly cleaned, the amount of current depends almost exclusively on the type of
feed water. The richer the water is in salts, the more current it conducts, and the sooner it reaches the required steam production
level. Over time, the salt deposit in the cylinder increases (as it does not evaporate with the water), contributing towards reaching
nominal production.
At full capacity, the required production level is automatically maintained by adjusting the absorbed current and maintaining the
water level in the cylinder.
The salt deposits that build up over time progressively exhaust the cylinder. To prevent excessive buildup, the humidifier
periodically automatically discharges and replaces a certain amount of water
