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.
Benets and Features
Achieves 20Pa back pressure as per BS EN 13141-8:2014.
6 SR700s can be connected to one SRC1.
Easy to maintain.
Low noise and vibration level due to expanded polypropylene housing.
Low prole wall mounted facia.
No additional duct work required.
Sleep mode sets the unit to its function at its slowest running. Returning to normal function after a set time.
Humidity mode provides ventilation rates suitable for when dwellings are unoccupied.
Intensive ventilation (Manual) to quickly remove any odours that are present.
Intensive ventilation (Automatic) to quickly remove excessive amounts of moisture and dangerous levels of Carbon dioxide in the dwelling
– (optional sensor required).
Cross ventilation mode for a constant ow of fresh cool air through the house without heat recovery.
Suitable for wall thicknesses of between 305mm to 700mm.
The ventilation rate for the SR700 can be congured for both large and small dwelling via the fan settings option in the service menu.

Commissioning & Controls
Operation
The fans can operate either in heat recovery mode (default) or in cross ventilation mode. In heat recovery mode, the fans will change direction
periodically. In cross ventilation mode, the fans will not change direction.
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
dwelling and recovering the stored heat when supplying air to the dwelling. 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 dwelling 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
The device can run 4 dierent fan speeds as dened by DIN 1946-6

The type of sensor will be detected automatically. For every type of sensor there are 3 threshold levels. The parameters are Humidity, CO and
VOC threshold. For humidity only, one of three dierent sets of thresholds can be selected in the service menu. See below table of thresholds.
Function threshold Fan speed Threshold value
CO2 threshold 2 800ppm
3 1000ppm
4 1200ppm
VOC threshold 2 800ppm
3 1000ppm
4 1200ppm
Humidity threshold low 2 35 %RH
Humidity threshold low 3 50 %RH
Humidity threshold low 4 65 %RH
Humidity threshold medium 2 40 %RH
Humidity threshold medium 3 55 %RH
Humidity threshold medium 4 70 %RH
Humidity threshold High 2 45 %RH
Humidity threshold High 3 60 %RH
Humidity threshold High 4 75 %RH
Whenever the lowest threshold is exceeded, the fan level will be set to the reduced fan level. The second threshold will trigger the nominal fan
level, and the third sensor threshold will request the intensive fan level. The fan level will be active until the corresponding threshold is undercut.
There is a hysteresis of 5%RH or 50ppm active when switching between the fan levels. Whenever the current fan level is manually altered, the
sensor driven fan level will be deactivated for the duration of 1 hour.
Sleep Mode
The SRC1 has a digital input which is used to activate Sleep Mode. The digital input requires a 220-240V~ supply via a switch, see Wiring, Mains.
It is mandatory that the External Digital Input Switch is supplied from the same phase as the SRC1 to avoid the risk of high voltage, which
could cause damage to the controller.
Operating the switch puts the unit into Sleep Mode; By putting the unit to sleep, fans can be congured to either stop (default) or slow to
humidity protection level for a period of time (default 1 hour) after which they will return to the previous setting. A second switch operation
before the timer has expired brings the controller out of Sleep Mode. Sleep Mode can also be activated by pressing and holding the down arrow
on the SRC1 keypad. The length of time the unit remains in Sleep Mode is congurable in the Service Menu. It is also possible to congure the
fans to run at one of the other fan speeds during Sleep Mode.
Filter Monitoring
The control unit has an integrated lter timer. The timer will operate whenever the fans are running. When the lter timer has expired the
"ERROR" LED will illuminate continuously. The lter timer can be reset by holding both right hand side buttons for ve seconds. The reset will be
acknowledged by all LEDs ashing three times.

Service Menu
The Service Menu can be used to congure external sensors and adjust other controller parameters and is based on the buttons and the LEDs.
In order to enter the service menu, the two left buttons have to be held for at least ve seconds. When in service mode, all three LEDs on the
left side (cross ventilation, heat recovery and error) will be activated, either ashing or permanently lighting up. By these three LEDs, the current
active service menu can be identied. When in service mode, the two left buttons can be used to move through the dierent settings of the
service menu. The right hand side buttons will change the selected parameter value. The three LEDs on the right side will be used to show the
value of the currently selected parameter. Each LED combination will represent a parameter value as shown in the table below.
Value LED Number
5 6 7
1 1 0 0
2 0 1 0
3 1 1 0
4 0 0 1
5 1 0 1
6 0 1 1
7 1 1 1
Whenever a value has been edited, it has to be saved rst, in order to take eect. To save the edited value, the button on the top left has to be
held for three seconds. The saving will be acknowledged by a ashing of the right side LEDs.
In order to leave the service menu, the left bottom button must be held for three seconds. The Controller will switch back to the normal
operation display. Whenever no button is pressed for a period of two minutes, the Controller will fall back to normal operation display.
