Setting maximum CH power
The maximum CH power is set at maximum in the factory. If less power is necessary
for the CH installation, the maximum CH power can be changed by changing the fan
rpm. See table Setting CH power.
This table shows the relationship between the fan rpm and the appliance power.

N.B. The power during burning is increased slowly and is reduced as soon as the set
supply temperature is reached (modulatie on Ta).

Setting pump setting
The ACV HRE Solo boilers are equped with a modulating A-class pump which
modulates on the basis fo the CH power provided. The minimum and maximum
capacity of the pump can be adjusted with the parameters 3 and c. Also see par. 7.2.
The set value of parameter 3. (max. pump setting) is the percentage of the maximum
pump capacity and is linked to the set maximum CH power as set with parameter
3
The set value of parameter
c.
(min. pump setting) is linked to the minimum CH-power
as set with parameter
c
If the CH load modulates between the minimum and maximum value, the pump
capacity will modulate along proportionately.
