9.2.2 Generating heat
Generation of the heat refers to a heating element.
During a heating request, the heating element outputs will be activated, with possibility of management of a switch-on
and switch-off duty cycle, defined by parameters rH6 and rH7 in a way to limit the heating power if very powerful resistors
are used, in order to prevent overheating in the cabinet.
The evaporator fan will go continuously or in parallel to the resistors output, at the speed established for the phase in
progress.
9.3 Regulation of humidity
The regulation of the humidity in the cabinet for all phases where it is envisioned and with humidity transducer enabled, is
neutral area.
Meaning with a work set-point and a neutral area within which activations of loads set-up for humidification or
dehumidification do not take place.
When the humidity goes above the neutral area value of the dehumidification differential value, the utilities set-up for
dehumidification will be activated until the humidity returns within the neutral area value.
In the same way, when the humidity goes below the neutral area value of the humidification differential value, the utilities
set-up for humidification will be activated proportionally until the humidity returns within the neutral area value. (For
management without humidity transducer, see chapter 0).
