Product Information
Designed to be used in pairs and in conjunction with a SRC1 the SR700s create a balanced
decentralised ventilation system with heat recovery. As part of a system multiple units provide
continual air circulation for your home, extracting stale moist air and replacing it with warmed fresh
air from outside.
The system provides an easily installed and maintainable solution for removing internal
condensation and eliminating mould growth within the home. Unlike regular extractor fans that
waste 100% of heat that passes through them from the home, the SR700 system will recover up to
94%, based on in house testing, of wasted heat. When used as part of a whole house system it can
be used to recover heat or provide continuous fresh air without heat recovery.

Controller Operation
Introduction
The controller has 2 modes of operation, Heat Recovery- which is the default and Cross Ventilation.
These are selected via the buttons on the left hand side of the controller. LEDs 1 and 2 indicate the
currently selected mode.

Heat Recovery Mode
In Heat Recovery Mode the Supply and Extract fans change directions at regular intervals, warming
the Heat Cell when extracting from the property and recovering the stored heat when supplying air
to the property. This is the default operating mode.
Cross Ventilation Mode
In warm weather when heat recovery is not required Cross Ventilation mode simply supplies air to
one side of the property and extracts from the other to create a cooling ow of air. By default Cross
Ventilation is continuous, but it may have a timer congured by the installer (4, 8, 12 or 24 Hours).
If a timer has been selected this will be indicated by LED 1 slowly ashing and once the timer has
expired the controller will return to Heat Recovery mode. A second press of the Cross Ventilation
button switches from timer to continuous.
Fan Speeds
By default the fans run at Nominal level which is indicated by LED 6. For normal use there are 2
other speeds, Intensive and Reduced which can be selected using the up and down arrows on the
right hand side of the controller. LEDs 5 and 7 will indicate when these speeds have been selected.
Additionally there is another speed – Humidity Protection which is below Reduced Speed and is
indicated by LED 4 being dimly lit. It is only recommended to use this level when the property is
unoccupied. In some installations the fans can be switched o by pressing the down arrow whilst at
Humidity Protection Speed; all LEDs are extinguished except LED 4 which ashes slowly. This is not a
default setting.
Timed Intensive Ventilation
The up and down arrows have additional functions; pressing and holding the up arrow for 2 seconds
puts the unit into Intensive ventilation for a timed period which by default is 1hour. LED 7 ashes to
indicate the unit is running on the timer and once the timer has expired the previously selected level
is returned to. Timed Intensive ventilation can be cancelled by pressing the down arrow.
Sleep Mode
Pressing and holding the down arrow for 2 seconds puts the fans into Sleep Mode; all fans will stop
for a period which by default is 1 hour. This is indicated by LED 4 slowly ashing; after the timer has
expired the fans restart at the previously selected level. Sleep Mode can be cancelled by pressing
the up arrow. In some installations Sleep Mode may set the fans to Humidity Protection rather than
stopping them. Sleep Mode can also be a Switched External Digital Input if one has been installed
and congured. Operating the switch puts the unit into Sleep Mode; a second switch operation
before the timer has expired brings the controller out of Sleep Mode.

10
Sensor Operation
If room sensors have been installed these will control the fan level depending on the environmental
parameter being measured. If the fan speed is being controlled by the sensor this will be indicated
by LEDs 5, 6 or 7 ashing quickly. The up arrow can be used to increase the ventilation rate above
the sensor determined level. The down arrow can be used to temporary override the sensor for 1
hour. After the hour has elapsed the fans will return to a level determined by the sensor readings.
Filter Timer
After 6 months of operation LED 3 – the warning Led will be constantly illuminated to indicate the
lters in the fan units require cleaning or replacing. Once the lters have been cleaned/replaced the
timer can be reset by pressing and holding down the up and down arrows together for 5 seconds.
LEDs 5, 6 and 7 will ash 3 times to indicate the timer has been reset and the warning LED will be
cleared.
Other Warnings
LED 3 is also used to indicate errors which may occur with the controller. The number of times the
LED ashes followed by a pause indicates the type of error, these are detailed below:
Number Error Error LED Indication Recommended Action
1Filter Timer expired LED ON Replace/Clean Filters & Reset Timer.
2 Self test failed 2 x FLASH - PAUSE Contact the installer.

Maintenance
Cleaning
Routine cleaning and lter changes are all that are normally required to keep the SRHRV System
working eciently.
Before cleaning ,power down the ventilation system and wait sucient time for the Fans to stop
rotating before starting cleaning.
SRHRV Fan Unit
Diuser
Remove Diuser before cleaning with a soft cloth damped with mild soapy water. To remove the
Bezel, un-clip the three legs that hold the Diuser to the Bezel.
Wiring Aperture Cover
Remove Wiring Aperture Cover before cleaning. To remove the Wiring Aperture Cover rst remove
the Diuser then using a screwdriver, place the tip in the indicated aperture and gently rotate.
Air Filter
Inspect every 6-12 months depending on environmental conditions. Remove loose debris using
a dry soft brush and a vacuum cleaner; do not use water. For replacement lters see Replacement
Filter section. Used lters should be dispose of as household waste.
Heat Cells
Remove the Heat Cell prior to cleaning. To access the Internal Heat Cell rst remove the Diuser,
Wiring Aperture Cover, Air Filter. To remove the Heat Cells use the wire handle and pull Heat Cell out
of the Vent Tube. Second Heat Cell can be pulled out in the same way after removing the Fan. Heat
Cells should be cleaned using a dry soft brush and a vacuum cleaner.

12
Fan
To remove the Fan carefully slide the Fan out of the Vent Tube, do not pull on the blades or wire.
Disconnect the Communication Cable before removing Fan. Fan should only be cleaned with a soft
dry brush.
Foam Fly Screen
Inspect every 6-12 months depending on environmental conditions. Remove loose debis as required
by rinsing with warm water. Ensure parts are fully dried before retting. For replacement lters see
Replacement Filter section. Used lters should be dispose of as household waste.
