7.3 Setting maximum CH power
The maximum CH power is set to 70% in the factory. If more power is required for the
CH installation, the maximum CH power can be changed by adjusting the rpm of the
fan. See table: Setting CH power.
This table shows the relation between the rpm of the fan and the unit power.
Desired CH power in kW (approx.) Settings on service display
(in % maximum rpm)

Caution:
The power is slowly increased when the fire is lit and is lowered when the set leaving
water temperature is reached (modulation on Ta).
7.4 Setting pump setting
The EHOBG**ABV1 CH boilers are fitted 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.

7.5 Weather dependent regulation
When connecting an outdoor sensor, the leaving water temperature is automatically
regulated dependent on the outdoor temperature, in accordance with the set fuel line.
The maximum leaving water temperature (T max) is set via the display. If so desired, the fuel
line can be changed by using the service code (see par.7.3).
