1.2. Navigator Control for HGL Technology
The following functional description is applicable to
IDM heat pumps type TERRA HGL with installed hot
gas heat exchanger and Navigator Control.
A prerequisite for the perfect operation of the control
system is clean work by the heating engineer and
electrician, as well as the proper commissioning of the
control system by a trained IDM service engineer.
The Navigator Control conforms to the EU Directives:
- 73/23/EC "Low voltage directive"
- 93/68/EC "Electromagnetic compatibility directive"
- EN 61000-6-2 "Electromagnetic compatibility -
resistance"
- EN 61000-6-3 "Electromagnetic comparability -
interference transmission"
- EN 61000-3-2 "Limit values for harmonic current
emissions"
- EN 61000-3-3+A1 "Limitation of voltage fl uctuations"
1.3. Structure of the Navigator Control
Description
The Navigator Control is comprised of a central unit
and the control unit. Furthermore, in accordance with
requirements, an internal heating circuit expansion
module for two additional heating circuits, as well as
an external heating circuit expansion module for three
additional heating circuits, can be connected. The
central unit also has an interface for a GSM module
as well as a stepper motor module.
Via an SD card slot, on the actual central unit, it is
possible to carry out evaluations using an event log.
