The order in which heating and dampers function is selected in the cascade
control system when there is a need to increase the room temperature.

DamperMin-Heat:

Heat-DamperMin:

When the temperature must be increased, the

heating output is first increased. When heating has reached maximum
output the dampers are driven to the heating period's minimum limit.

When the temperature must be increased, the

dampers are driven to the minimum limit of the heating period and after
that the heating output is increased. The most commonly used cascade
control principle.

Minimum limit

during heating

Vinkki !

If the heating output need is greater than the available

maximum heating output (e.g., HRU defrost), the amount of

fresh air is decreased to ensure a sufficient heating output.

Reason:

Vinkki !

For energy saving reasons, a smaller amount of fresh air is

used during heating.

Reason:
