5.8. SETTING THE PROTECTED PARAMETER "SEASON"
The RePuro heat recovery unit can be selected to operate according to control logics SUMMER or WINTER. Both seasons offer a series of control func-
tions:
• Control on external air temperature: This logic avoid that too cold air (from 0 ° C to -10 ° C or -15 ° C depending on the version) risks freezing the
heat exchanger. To avoid this possibility it intervenes with the electric pre-heater (if present or enabled), or reduces in a gradual manner the supply fan
speed until it is switched off.
• Control of freecooling function: In situations that permit it the heat recovery unit has the capability of exhausting the room air without passing
through the heat exchanger. This avoids that the supply air to the room is heated or cooled by the exhaust air. This operating mode could be particularly
useful in the summer season in that the external air temperature could be lower than the room temperature. In this case the use of external air, without
any exchange of heat, permits cooling for free (freecooling).
To select the season it is necessary to enter in the password protected menu (as shown in paragraph 11.7), display the parameter
MODE/SELECT key to enter in parameter modification mode. Use the navigation keys to set the desired value (value 0 is the SUMMER season, value 1 is
the WINTER season), then press the MODE/SELECT key again to confirm the selection and exit from the parameter modification mode.
