DRI-ECO3S-HEAT-HC
Installation Manual
6.4 Setting Temperature Operating Mode
When delivered, the unit is set to temperature operating mode setting
of 1 as a default. To change this setting, switch the power to the unit
on (via the supplied isolator). The display in the ceiling vent will show
the start-up pattern for two minutes and the unit will begin running
at speed 6. In this time you can change the temperature setting by
pressing and holding the “up” switch. The display will show a flashing
value of 1 and will increase every 4 seconds. Once you have reached the
temperature setting you require press and release the “down” button to
store the setting. The fan will now enter into its normal speed setting
mode and a speed can be selected at this point.

7.0 WIRELESS SENSORS & SWITCHES
The Drimaster RF system can simultaneously accommodate one
DRI-ECO-RH, one DRI-ECO-CO2 and one switch type, either
DRI-ECO-2S or DRI-ECO-4S.
Multiple devices of the same type are
not supported.
7.1 RF Frequency
RF enabled DRI-ECO devices operate at a frequency of 868.3 MHz.
7.2 Installing 4 Way Switch (DRI-ECO-4S)
The switch is provided with an adhesive foam pad to allow quick and
easy mounting to the wall. Alternatively the switch may be mounted to
the wall using the fixing plate (screws are not provided).
Remove the switch fixing plate by inserting a flat head screwdriver in
the rear of the switch on the left or right side, underneath the fixing
plate and gently lever up the plate until the fixing lug releases. Repeat
for the opposite side. This will give access to the battery compartment
on the rear of the PCB and release the fixing plate. Reassemble the
remaining components and press into place, an audible click will be
heard. 1x CR 2032 battery is provided and expected lifetime is 10 years
under normal use.
Normal -
If the normal button is used the unit will return to its
standard operation programmed at the diffuser.
Boost (Purge) -
If the boost button is used, the fan speed will increase
to maximum and a ‘P’ will be shown in the display. Boost is active for
2 hours from when the Boost button is pressed.
Boost mode will not
operate if a unit is in standby mode (above 24°C in loft).
Heater auto -
If the heater auto button is used, the heater switches
on/off automatically as needed.
Heater off -
If the heater off button is used 'Heater auto' will be
disabled and the heater switches off.

7.3 Installing Humidity Sensor (DRI-ECO-RH)
The front panel of the sensor must first be released by pressing in the
plastic fixing lug located on the bottom edge of the sensor. The panel
may now be removed and the sensor mounted on the wall in a suitable
location (screws not provided). 2x AA batteries are provided.
Boost (Sensor) -
If a sensor set point has been exceeded, the fan speed
will increase to maximum and a solid ‘b’ will be shown in the display.
Boost mode increases the speed setting by 1. If the unit is running at
speed 6, boost is ignored (i.e. A unit is running at speed 3. A boost
signal is received from a sensor whereby the speed changes to 4. When
the boost condition clears, the unit will revert to speed 3).
