Electric heater/KM heater/PWW heater
Depending on the configured heating type, different parameters are decisive.
The start temperature for the heater is entered as a negative difference to the room
temperature setpoint. ➊
The corresponding hysteresis for the heating stop is only valid for heaters with 2 step
control.➋
For proportional electric heaters/PWW heaters, you can adjust a gradient, which deter-
mines the temperature range in which the heating capacity increases from 0 to 100 %.➌
Alarm parameters:
Electric heater alarm time delay ➍
Only the first electric heater can be controlled proportionately. If this is the case and
several heaters are present (max. 3), then only the start value and the gradient of the
first heater are decisive for the control.
Every time the proportional heater reaches 100 % heating capacity, a further heater is
switched on and the capacity of the first heater is reduced to 0 %. Therefore, 3 separate
heaters work like an overall heater. (see below)

7.2.3 Air circuit, internal components
The electric heater(s) is/are switched off if at least one fan runs under the minimum speed
or is switched off.
