Elsys comfort sensors check for Humidity + CO2 + Temperature.

Check here the checklist for installation: Checklist for installation

Double sided tape (see Tabs Sensors installation guides for more information)

Hubs

Elsys connect over the LoRa network. Make sure you install your LoRa hub before installing the sensors (check out LoRa Gateways / Hubs installation guides for more information).

Sensor Installation

1. Decide HOW to install

• Check if locations apply to prerequisites

• chest-level (1m60/5.25 feet), preferably next to a light switch or HVAC control unit

• not over a heating body or in direct sunlight

• not behind a cupboard, a tv, ...

• Indicate on the Sensor Plan where to place all sensors, incl where the sensor placement deviates from this normal procedure

2. Prep the sensor

If 1 sensor (or just a few) is purchased, the batteries are IN the sensor; they can be activated by pulling the tab.

2. Install the batteries. The ERS CO2 requires one or two AA batteries. The battery type is 3.6V Lithium Battery (ER14505). You can use one battery, but it’s recommended that you use two for best performance and battery life. Use battery slot A if only one battery is used.Image Removed

Caution: Using batteries other than the ones provided may result in loss of performance and battery life, and also damage to the device. Dispose of properly, observing environmental protection rules.

3. Mount the back panel on the wall using some of the six mounting holes: there are 6 points where you can set a screw, mount using at least 2 screws. Alternatively, it can also be mounted using adhesive tape.Image Removed

Caution: This device must not be placed near any louver, air vent, or other places exposed to fresh air (e.g., windows, door openings). Such placement will give false CO2 values.
