tion cycles (s. 6.1.1.2)
If the variable output is not used in minimum ventilation:
The output starts at variable outputs’ absolute minimum speed (as defined in section 4.4).
THE LAST FAN STAGE MUST NOT BE CONFIGURED IN VARIABLE MODE.
IF THE LAST FAN STAGE USES A VARIABLE OUTPUT, IT MUST BE SET AS AN ON/
OFF OUTPUT (S. 4.7).
The bandwidth defines the interval over which the variable output goes from mini-
mum to full speed. This is true even if full speed is never reached as in the example
above. When the start temperature of stage 2 is reached, the variable output drops to
its minimum speed. The same bandwidth is then used to increase the speed when the
room temperature increases.
The bandwidth can be adjusted according to the outside temperature. Refer
to section 4.7 to activate this function.
6.2.1.3 Outside Temperature Compensation
Stages 1 and 2 bandwidths can be adjusted automatically as a function of outside
temperature compensation. As the outside temperature decreases, stages 1 and 2
bandwidths increase gradually to compensate for the change. The user specifies the
bandwidth used in summer as well as the bandwidth used in winter for both variable
