The automatic CHIPS control
Depending on the implementation, the unit may be equipped
with an automatic CHIPS control.
The CHIPS control automatically adjusts the strength and heat
of the unit to changing weather conditions. Thus, in all situa-
tions the energy loss is minimal and the comfort maximal.
CHIPS stands for "Corrective Heat and Impulse Prediction Sys-
tem".
Control when unit 'on'
The unit andthe automatic controlwere developed for situa-
tions in which the door stands open.
For the most efficient climate separation and preservation of
comfort it is important that the airflow just touches the floor
and is heated sufficiently. The unit continuously measures the
values that are needed in order to achieve this:
1. The installation height (entered in the control panel)
2. The temperature difference between the two rooms:
- outdoor temperature
- room temperature
3. The temperature of the discharged air
As soon as the situation changes, the control adjusts the out-
let flow rate and the temperature of the airflow to that.
Control with unit 'off '
If the unit is off – at night, for example – it is not active as cli-
mate separation.
If it is off, the unit can indeed still perform other functions:
• The unit can be set to keep the room at a minimal 'night'
temperature.
• Water-heated models are equipped with integrated frost
protection.
