2.0 INTRODUCTION
The DRI-ECO-HEAT-HCS provides whole home ventilation using
the Positive Input Ventilation principle. The concept is to introduce
fresh, filtered air into the dwelling at a continuous rate, encouraging
movement of air from inside to outside. To achieve this the unit is
mounted in the loft space, drawing air through the filters and inputting
it, at ceiling level, into the property.
The DRI-ECO-HEAT-HCS fan unit includes an internal sensor to
regulate the fan speed according to the temperature of the loft. The
internal sensor is to increase airflow to the dwelling when the loft is
warmer than the house. The units ‘Fixed Temperature Heat Recovery’
strategy shall be achieved via a sensor located in the unit and shall
improve energy performance accordingly. This unit has all the controls
for the fan in the ceiling vent allowing the user to control, programme
and monitor the unit from inside the property. A heater section
incorporating a 400W heating element shall be fitted to the fan unit.
It shall be electronically controlled so as to minimise energy use. A
temperature sensor shall be fitted to the outlet of the heater and will
control the output of the heater in an attempt to maintain the set
point. The set point will be adjustable between 5˚C and 15˚C.
Once installed, the airflow can be set to suit the house size and, if
required, the way it responds to the temperature changes within.
3.0 GENERAL INSTALLATION
Successful operation of the fan depends entirely upon the unit being
installed strictly in accordance with these instructions.
Please read through this guide in its entirety before commencing
installation and follow step by step to ensure a satisfactory completion.
Whilst the installation of the unit may be achieved by suitable persons,
the provision of the electrical supply and the connection of the unit to
