DRI-ECO3S-HEAT-HC

3 Storey Whole House Ventilation Unit with  
RF Enabled Hall Control and Heating  

Installation Manual

1.0 SAFETY INFORMATION

• 

The provision of the electrical supply and the connection of the DRI-ECO3S-HEAT-HC unit to the 
mains must be carried out by a qualified electrician.

• 

Isolate from power supply before removing any covers. During installation/maintenance ensure 
all covers are fitted before switching on the mains supply.

• 

Means for disconnection must be incorporated in the fixed wiring as shown in the wiring diagram 
in accordance with IEE wiring or national wiring rules.

• 

In order to avoid a hazard due to inadvertent resetting of the thermal cut-out, this appliance 
must not be supplied through an external switching device, such as a timer, or connected to a 
circuit that is regularly switched on and off by the utility.

• 

The fan unit is supplied with a fused spur. The three core mains cable from the fan unit should 
be connected to a fixed wiring installation, via the spur, in accordance with current IEE wiring 
regulations.

• 

If the mains supply cord to the PSU is damaged, it must be replaced by the manufacturer, its 
service agent or similarly qualified persons in order to avoid a hazard.

• 

The heater unit must be connected to the ceiling vent and fan unit using the 3 looms that 
protrude from the heater module. 

• 

Disconnection from mains must be incorporated within the fixed wiring and shall have a 
minimum contact separation of 3mm in accordance with latest edition of the wiring regulations.

• 

The CO2 sensor requires a 230V power supply. Remove the front panel as per the humidity 
sensor and release the terminal cover via a fixing lug on the rear of the sensor. Refer to the 
wiring diagram provided and connect the supply to the terminal box. Finally the sensor may be 
mounted to the wall (screws are not provided). 

• 

It is important to ensure that the diffuser is NOT placed within 1 metre of a smoke alarm. If the 
diffuser cannot be repositioned, two sides of the diffuser must be closed off using the air dams 
supplied to encourage the air through the remaining open sides that faces at least 1.5 metres of 
unobstructed area away from the smoke alarm sensor.

• 

If the unit is required to switch off in the event of smoke/CO detection, alarms are available with 
separate relay bases from 3rd party companies. This is a mandatory requirement for all units 
installed in a 3 Storey property.

• 

The flexible duct (maximum length 2m) is connected to the main unit by inserting the duct over 
the outlet duct and held in place using the supplied cable tie.     

• 

When installing the duct to the heater unit, insert the duct over the back of the heater, over 
the protruding screw heads (3mm from the face of the duct) and fasten the cable tie below the 
screws. This ensures that the duct will be held on securely, check all duct joints are air tight.
