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. Benefits 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 profile 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 flow 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 configured for both large and small dwelling via the fan settings option in the service menu.

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 flow of air. By default Cross Ventilation is continuous, but it may have a timer configured by the installer (4, 8, 12 or 24 Hours). If a timer has been selected this will be indicated by LED 1 slowly flashing 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 different fan speeds as defined by DIN 1946-6 Fan setting 1 (Large dwelling) Sleep Mode** 6.5m3/h or Off Off** Humidity Protection 6.5m3/h Reduced 20m3/h Nominal 40m3/h Intensive 60m3/h Fan setting 2 (Small dwelling) Sleep Mode** 6.5m3/h or Off Off** Humidity Protection 6.5m3/h Reduced 10m3/h Nominal 17m3/h Intensive 25m³/h **Configurable in the service menu Sensor Mode When sensors are used, the number connected is entered via the Service Menu and the correct number selected on each sensor encoder (see image). See below table for encoder settings. Quantity of Sensors Encoder settings Sensor 1 Sensor 2 Sensor 3 Sensor 4 1 0 X X X 2 0 1 X X 3 0 1 2 X 4 0 1 2 3 Controller Decrease Speed Heat Recovery Humidity protection Cross ventilation Heat recovery Error Reduced speed Nominal Intensive speed Increase Speed Cross Ventilation Decrease Speed Heat Recovery Humidity protection Cross ventilation Heat recovery Error Reduced speed Nominal Intensive speed

VOC threshold. For humidity only, one of three different 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 configured 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 configurable in the Service Menu. It is also possible to configure the fans to run at one of the other fan speeds during Sleep Mode. Filter Monitoring The control unit has an integrated filter timer. The timer will operate whenever the fans are running. When the filter timer has expired the "ERROR" LED will illuminate continuously. The filter timer can be reset by holding both right hand side buttons for five seconds. The reset will be acknowledged by all LEDs flashing three times. Sensor PCB, Encoder Highlighted

In order to enter the service menu, the two left buttons have to be held for at least five seconds. When in service mode, all three LEDs on the left side (cross ventilation, heat recovery and error) will be activated, either flashing or permanently lighting up. By these three LEDs, the current active service menu can be identified. When in service mode, the two left buttons can be used to move through the different 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 first, in order to take effect. 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 flashing 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. The different parameters in service menu are shown in the table below.
