7. Using the optional Wireless Boost Switch
7.1. Open the wireless boost switch by inserting a flat bladed screwdriver in the slot at the bottom. Make sure that
the system address, (set by the 6-way DIP switch), on the wireless boost switch PCB matches that on the wireless
receiver PCB. The transmitter address on each wireless boost switch, (set by the 2-way DIP switch), should be
different if you have more than one wireless boost switch.

7.2. Fit two AA batteries to the wireless boost switch. Remove the plastic tabs between battery and terminal.
Battery life will be dependent on the capacity of the battery (measured in mAh), how many times the transmitter
buttons are pressed, how long the boost intervals are and whether or not the LS connection is used. Accessories
can be connected to the volt-free and Ls connections so that the wireless boost switch sends a boost signal on the
accessory's behalf. Turn to page 34 for wiring diagrams.
7.3. The little light above the "Max" button will light up when a button is pressed.
7.4. Pressing the "Max" button will send a signal wirelessly to the Sentinel Multivent telling it to run at Boost speed
for 15 minutes. Pressing the down and up buttons will adjust the overrun time in 5 minute increments. The LCD will
count down the time in minutes. If more than one of the wireless boost switches are calling for Boost speed, the
Sentinel Multivent will prioritise the longest overrun time period requested. The Sentinel Multivent may continue to
run at Boost speed after the timer has timed out if another accessory or switch is calling for Boost speed.
7.5. Purge Feature: Pressing and holding the "Max" button for more than 5 seconds will send a signal telling the
Sentinel Multivent to run at maximum speed for 2 hours. Maximum speed is likely to be higher than Boost speed,
depending on the size of the system installed.

8. Servicing and Maintenance

WARNING: THE FAN AND ANCILLARY CONTROL EQUIPMENT MUST BE ISOLATED FROM THE
POWER SUPPLY DURING MAINTENANCE.
8.1. At intervals appropriate to the installation, the fan should be inspected and cleaned to ensure there is no
significant build up of dirt or other deposits. To inspect the inside of the product isolate the power, remove the
cover, remove the scroll assembly by unclipping the clips in each corner and pulling away. If necessary, vacuum the
inside of the Sentinel Multivent.
8.2. The fan has sealed for life bearings, which do not require lubrication. Expected service life is at least 45,000
hours continuous running.
