DESIGN AND OPERATION - The ventilator consists of a telescopic air duct with adjustable length regulated by the position of the inner air duct inside the outer air duct, the ventilation unit, and the ventilation hood. - F7 filter+prefilter and the ceramic energy regenerator are located inside the inner duct. The filters are designed to purify supply air and prevent foreign objects from ingress into the regenerator and the fan. - The ceramic energy regenerator extracts energy from exhaust air to warm up or cool down supply air. - The regenerator is equipped with a pull cord inside to facilitate its withdrawal from the ventilator. The regenerator is installed on an insulation material which is used as a sealant as well. - The ventilator is available to be installed from the inner side of the wall.
INSTALLATION AND SET-UP Read The User’s Manual Before Installation The Ventilator To prevent room dust deposition and accumulation, the ventilator must not be installed in places where the air duct may be blocked by the blinds, curtains, drapes, etc. Meanwhile, curtains might obstruct normal airflow in the room, making ventilator operation inefficient. OPERATION MODES Ventilation Mode. The ventilator runs in exhaust or supply mode at a set speed. When synchronous operation of two connected ventilators, one runs in the supply mode and the other in exhaust mode. Regeneration Mode. The ventilator runs in two cycles of 75 seconds each, to provide heat and moisture regeneration. Interval 1 The warm polluted air is extracted from the room and goes through the ceramic regenerator, which gradually absorbs heat and moisture. After 75 seconds the ventilator switch to air supply mode. Interval 2 The fresh and cold outdoor air goes through the heat regenerator and absorbs the accumulated moisture and heat after 75 seconds, when the energy regenerator gets cold, the ventilator switches to the exhaust mode.
2. Pull the mobile bracket into the outer duct back into place so that the silicone ring on the outside of the outer duct is tight against the outer wall. Fill the space between the wall and the outer duct with the PU glue provided in the kit before attaching the back cover mounting plate, and then wait for the glue to dry. Then install the back cover mounting plate, align the round hole of the back cover the mounting plate with the round hole on the wall, and measure the level of the mounting plate with a level ruler to ensure that the mounting plate installation is horizontal, then mark the hole, punch in the expansion rubber grain, then align the mounting plate with the hole and fixing it with a screw. 3.

1. Without setting a leader/follower role, one remote control can control one or more devices. 2. After setting the leader/follower role, the current use of the remote control can only control the leader, and the leader will send the synchronization signal to the follower (the follower does not receive the remote control signal), so that the follower mode is synchronized with the leader. (The leader can only control one follower alone). 3. In regeneration mode, the operation direction of the follower fan is opposite to that of the leader, and the direction of the follower fan in other modes is the same as that of the leader. • The maximum linear unobstructed communication signal distance between leader and follower is 15m. • The signal from the leader and follower can pass through a 180mm thick brick wall.
Follower Unit Settings 1. Connect the device to power. In the OFF state, as shown in the figure, long press the mode button of the device for 5 seconds, and the status indicator green light flashes slowly. At this time, the device enters the leader-follower linkage mode, the unit is set to the follower role. 2. During the leader and follower set pairing mode, it should be carried out at the same time for a limited time (within 1 minute). The devices should be as close as possible, the device will be automatically connected. 3. The status light of the paired devices will change to blue light ON to indicate that leader-follower pairing is successful. 4. If the leader-follower pairing fails, the status lights on the devices will flash for one minute and then light-off automatically. ▶ LEADER-FOLLOWER RESET AND CANCELLATION Connect the device with power. In the OFF state, long press the fan speed button of the linked device for 5 seconds, and the device status indicator blue light flashes slowly. At this time, the linked device enters the leader-follower linkage mode, the device definition is the leader role.
