In case of a flow switch alarm during recovery circuit operation, the related compressor will
trip and the alarm reset will not be allowed up to the flow is recovered (otherwise recover heat
exchanger freeze will occur).

Recovery control
When heat recovery is activated the control will activate or deactivate recovery circuits with
a step logic.
In particular a next heat recovery stage is activated (a new heat recovery circuit is inserted)
if the heat recovery leaving water temperature remains below the setpoint by an amount greater
than an adjustable regulation band for a timer greater than an adjustable value (heat recovery
interstage). When a recovery stage is requested, the relative compressor is completely downloaded
and then the recovery valve is energized. After recovery valve switches the compressor load is
inhibited until the saturated condensing temperature is lower than an adjustable threshold (default is
30.0°C).
At the same manner a heat recovery stage is deactivated (a heat recovery circuit is
removed) if the heat recovery leaving water temperature remains above the setpoint by an amount
greater than an adjustable dead regulation band for a timer greater than the previous defined value.
An high temperature setpoint is active in the recovery loop; it will disable all recovery
circuits at the same time if the heat recovery water temperature rises above an adjustable threshold
(default 50.0°C).
A three-way valve is used to increase recovery water temperature at startup; a proportional
control is used to establish valve position; at low temperature the valve will recirculate recovery
water, while at temperature increasing the valve will bypass a portion of the flow.

Two levels of limits are included in the control:
