REMOTE CONTROL INSTRUCTIONS

Sentinel Dehumidifiers can be controlled using an optional remote accessory.The Sentinel 
Remote Control connects to your Sentinel Series Dehumidifier via a 25' CAT 5 cable. The 
remote control contains an integrated sensor which gives you multiple options for remotely 
controlling your unit, in addition to monitoring the conditions surrounding the dehumidifer.

One application for the remote control is to install the dehumidifier in one room with the 
conditioned air ducted into a second room that contains the remote. For example, the 
dehumidifier could be installed in a laundry room and ducted into a living room. The remote 
would then be mounted in the living room so the remote sensor can control the humidity and 
provide easy controls for the user.

Another useful application for the remote control is if the dehumidifier is in area that's 
difficult to access on a regular basis. For instance, if your dehumidifier is installed in your 
crawl space, the remote could be mounted in your living space or garage. This provides you 
with an easy way to monitor the dehumidifier.

NOTE: Symbols indicated below will only appear when the dehumidifier is powered on.

Press the on/off button and the 
machine will start running (two 
beeps). Press the button again to 
turn the machine off.

Use the Up and Down arrow 
buttons to adjust the humidity 
level.
