Ventilation requirement of up to 325 m3/h.
VPL 15 is for anyone who wants ventilation with highly efficient heat recovery, and comfort heating and cooling.
The system extract hot, humid air from e.g. the kitchen, bathroom and utility room, at the same time removing dust particles, moisture and odours from the home. Furthermore, the energy from the extract air is used to heat or cool the incoming air. The system can be equipped with supplementary heating elements that can be connected to an electric or central heating system. VPL 15 will produce a comfortable incoming air temperature even in the coldest winter weather.
When you buy VPL 15, you get a comfortable and healthy indoor climate and cost savings on your heating bill.
The systems are suitable for locating in an attic space.
Filterunit
To the VPL 15 system is it possible to connect a filter unit with a built-in heatpipe (passive heat exchanger). The heat pipe increases the heating effect with up to 40 % in the cold season – without using extra electricity.
CO2-sensor
With a CO2-sensor installed, the ventilation speed can be pre-programmed with CTS 602 to run at a higher ventilation steps when CO2 reaches high level in the extract air. CO2-level is programmable.
Electrical heating surface incl. regulation
When you fit an electrical heating surface, you can raise the fresh air temperature to the desired level at any time. The electrical heating surface is supplied ready to fit into the fresh air duct and, for easy fitting, the device is pre-fitted with all the required sensors.
EM-box
An EM-box allows heat recovery from the air from the range hood and thereby helps to heat the supply air. The EM-box is equipped with a steel filter which efficiently cleans the range hood air of fat particles and thereby protects the system.
Expansion PCB
The expansion PCB provides additional functions for the CTS 602 control unit, e.g. controlling the EM-box.
Installation kit
The installation kit comprises of four vibration absorbers and a water trap for the condensation outlet. The water trap can be ordered separately.
Heating cable
To protect the condensation outlet against frost, a 3 metre-long self-regulating heating cable can be ordered.
Water heating element incl. regulation (duct mounted)
The supply temperature can always be raised to the required level using a water heating element. The water heating element is designed to be built into the duct and must be connected to the primary heating supply. Supplied with two-way adjustment valve, temperature sensor and frost thermostat.
FU 15 - Filter unit with heat pipe
An option is a FU 15 filter unit with heat pipe, which is connected to the VPL 15 unit.
The heat pipe slightly raises the temperature of the outdoor air, thereby increasing the heat pump’s efficiency in the VPL 15 aggregate significantly during the winter.
With an integrated FU 15 filter unit with heat pipe, in most cases there is no need for a heating coil with mixing circuit.
VPL 15 is an energy-efficient ventilation unit for heat recovery and cooling of homes and small commercial buildings with a ventilation requirement of up to 325 m3/h.
Heat recovery is via a heat pump that can utilise the recovered energy better than with e.g. a counterflow heat exchanger.
The heat pump has a reversible cooling circuit, which means that the unit can both heat and cool the air.
VPL 15 is supplied fully tested and ready for use. Fitting and commissioning must be carried out by an authorised electrician or plumber.

VPL 15 is controlled using its CTS 602 operating panel, featuring a wide range of functions, e.g., menu-controlled operation, weekly programme settings, filter monitor with timer, fan speed adjustment, summer bypass (free cooling), supply-heating element control, error messages etc.
The CTS 602 comes with factory settings, including a default setting which can be customised to operational requirements to achieve optimum operation and utilisation of the system.
The operating panel must be placed in a dry, frost-free location, at least 1.5 m above floor level and at least 0.5 m from any corner. Avoid placing the panel on an external wall or in areas in direct sunlight.
Operating instructions for the CTS 602 can be found in a separate user manual supplied with the unit.
