Analogue control including the following functions
Dehumidification
Automatic defrosting
Heating (accessories)
Ventilation (accessories)
Equipment list
Fan, heat pump unit for energy recovery (equipped with compressor, evaporator, condenser, filter dryer, safety refrigerant R407C), condensate collecting tray, air filter, height-adjustable feet, and switching unit with control
Housing
Stable, corrosion-resistant profile frame construction made of aluminium hollow chamber profiles, powder-coated. The profiles are thermally decoupled by means of integrated plastic webs, so that the heat transfer between the device chambers and the environment can be reduced to a minimum level. Cladding panels equipped with highly insulating Hydrotec foam core.
Supply air fan
equipped with energy-saving, stepless EC direct current motors.
Exhaust filter
Slide-in frame equipped with a Z line filter. Filter cell with pleated filter medium, fully incinerable and metal-free.
Heat pump unit
Heat pump unit equipped with a fully hermetic rotary piston/scroll compressor, evaporator, epoxy resin-coated condenser; bypass flap, condensate pan with drain
Switching unit and regulation
integrated in the device with all modules for all tasks in the fields of control and monitoring.
Room hygrostat
Control EWPCON B
Microprocessor control with the following functions:
- Dehumidification
- Automatic defrosting
- Heating (accessories)
- Ventilation (accessories)
