I changed the Target temperature, but it goes back after a time

Check if the device is not under a Heating Profile in Enterprise and either disable it or adjust the boost time. Learn more in the articles below:

https://docs.mclimate.eu/mclimate-enterprise/configuration-and-management/buildings/heating-profiles

https://docs.mclimate.eu/mclimate-enterprise/advanced-features-and-use-cases/boost-mode

What is Child Lock

Child Lock is a functionality that disables the manual control of a device. It is turned off by default, however you can toggle it via a command and/or a button combination. Consult your device's User manual and/or the MClimate Device Documentation Center for the specific command.

How long will my Device's battery life be

MClimate devices last 10+ years with default settings and the included batteries, operating at nominal conditions.

In case you want to obtain an estimation of your battery life, with custom settings, you can use the online calculator below: https://mclimate.eu/pages/lorawan-battery-calculator

You can also obtain a Battery estimation directly from your Device Dashboard in Enterprise, learn more in the article linked below:

https://docs.mclimate.eu/mclimate-enterprise/configuration-and-management/devices/battery-estimation

How to reset my MClimate devices:

MClimate devices can not be factory reset. They come pre-provisioned with the necessary Dev EUI, App/Join EUI and APP Key for LNS provisioning. These are hard-coded and can not be changed by the client, thus they remain with the factory default settings.

The only way to initiate a new join-request is by power cycling the device or with a specific button combination. Consult your device's User Manual for instructions

Any other parameters you can change via downlink commands.

Can MClimate devices be configured/upgraded via a computer/phone

This is not possible, MClimate devices can only be interacted with via downlink commands or via the MClimate enterprise platform. This is also the best way to Upgrade your firmware via FUOTA (details on the procedure in the link)

FCT working voltage

The MClimate FCT (Fan Coil Thermostat) works in the 100-240VAC 50Hz range. It not work on 24VDC itself and can not control 24VDC FCUs (Fan Coil Units).

How can I decode/parse the payload

We offer payload decoders for all of our devices you can find they in the MClimate LoRaWAN Devices documentation page. The location of the decoder/decoders is the same for every device, in the Uplink decoder section, for example here is the one for Vicki.

Dev EUI, App EUI and App Key - what are they and how to get them

The aforementioned EUIs and Key are required to register any LoRaWAN device, including MClimate ones with your LoRaWAN Network Server (LNS) of choice. If you purchased a product directly from our online store you will receive an automatic response via email from the address [e-mail]. The information will be provided in the for of a CSV file.

MClimate devices can not have their Dev EUI, App EUI and App Key changed in any way from the customer. You can't use commands to change them and any reset/power cycle would not change them.

If you purchased from one of our distributors, contact them instead.

Is my TRV compatible with Vicki

Vicki has a M30x1.5 fitting, thus it should be compatible with most such TRVs. However, in case you are unsure, or using a different fitting size you can doublecheck via our TRV Compatibility tool.

In case you still can not determine if Vicki is compatible with your heating system contact us at [e-mail]

Vicki displays a strange symbol after pressing the button on the back

8, 8о, 88, 77, 55 and so on (basically all numbers outside of the 5-30 temperature range) are codes for functional tests performed on the factory floor. If you have pressed the button on the back you might have ended up with one of the aforementioned displayed.

In order to take the device out of testing mode and into normal operation mode you need to do the following: Press the button on the back - the indicator starts showing "o8" Rotate the device - changes to "o" Mount the device and wait for calibration - it’ll show "77" Demount and press the button on the back - you’ll see "HI"

Vicki can not be reset in any way by the button on the back and pressing it will neither reset it to factory default nor reboot it. DO NOT PRESS the button as it is not intended for normal operation mode.

You can refer to the linked video to see the whole procedure. https://www.youtube.com/shorts/jpvSV9T_vkk

How to power/start MClimate Devices with a solar panel

MClimate devices with a solar panel like the Wireless Thermostat, CO2 Display Lite or the HT Lite come without batteries (or can't use any at all). Their internal supercapacitor is pre-charged and you should be able to power them right away. Look in the manual of the specific product for the location of button, either on the side or on the back, pressing it will activate the device.

What Fport are used by MClimate device

All Mclimate devices transmit their uplinks on Fport 2.

You can send downlinks on any of the following ports: 1, 2, 4-223

What is the hole on top of Vicki for

It is not a reset, this is where the H&T sensor's location. The opening is required to obtain valid readings.

This is not a reset button hole, there is no button there to press. Do not try to reset the device using a pin and pressing in the hole. THIS WILL DAMAGE THE DEVICE.

How many Vickis can be controlled externally

You can control as many Vickis as you like with an external thermostat, in a addition you can take temperature reading externally and forward it to the Vickis. Take a look at the following article to gain insights on how to set up External control and measurement via Enterprise: https://docs.mclimate.eu/mclimate-enterprise/advanced-features-and-use-cases/vicki-external-temperature-control

Can the FCT control a split system

The Fan Coil Thermostat is not compatible with AC Split systems. It is designed for Fan Coil Unit (FCU) system control. If you need to control a split system, we recommend the MClimate Melissa: https://mclimate.eu/products/melissa-smart-wi-fi-a-c-controller

Vicki US915 and FCC compliance

MClimate devices including Vicki are fully compatible with the LoRaWAN 1.0.3 specification. This includes the US915 band. This being said, the device is undergoing FCC certification at the time, which is not yet completed.

What is the stroke/step of Vicki

According to the datasheet Vicki has a step of 0.00208mm. This is the linear movement of the piston related to a single step rotation of the motor. However, there is a scaling factor of 4 that needs to be applied for practical measurements.

For example, a motor position of 500 steps would mean: 500 x 0.00208 x 4 = 4.16mm. This is how much the piston will extent, pushing the TRV pin, assuming that it has calibrated to 500 steps motor range.

Vicki displays HI but nothing happens

At this point Vicki should have attempted to connect to the LoRaWAN network, check you gateway/LNS for a join request/accept.

Make sure you have properly installed the Vicki head on its backplate (that has been properly fitted to a valve beforehand). If the aforementioned are in order Vicki should start calibrating at this point and enter normal operation mode within a minute or two after calibration has been finished. Refer to the link below for the proper installation procedure:

Can I turn the display of Vicki off

This is not possible, a physical interaction with the crown will always results in the display lighting up and showing the state of the device.

In case you want to limit the information your tenants are seeing, for example if the Vicki is controlled fully remotely you could enable the Child Lock functionality, which will result the "Ch" message being displayed only. Lear more about the functionality at the link.

How is Vicki controlling the temperature

If you are using Firmware Version ≥4.3 and up Vickis is using a PI algorithm to dynamically adjust the TRV opening in order to best reach and maintain the desired Target temperature. You can learn more about the algorithm at the link.

What is the operating voltage of Vicki and when should I change batteries

Vicki works within the 2.7 - 3.6 VDC range.

We recommend scheduling a battery replacement once they drop below 2.8VDC to make sure you have no interruption in service, as once the level gets near 2.7VDC there might be insufficient power/force to close some valves.

What are the Motor position and Motor Range of Vicki

When Vicki is installed it calibrates to the specific TRV it is mounted on. It determines the fully open and fully closed state of the valve and maps them to two parameter values:

Motor Range - corresponds to the fully closed state (determined via the calibration process), depending on the specific TRV this ranges between about 350 and 600

Motor Position - this is the current position of the Vicki's motor, that corresponds to what extend the valve has been closed.

Motor position = 0 - the valve is FULLY OPEN

Motor Position = Motor Range - the valve is FULLY CLOSED

Vicki is stuck in the closed state

Sometimes TRVs get stuck (especially ones that have been in use for some time and have had a long time off of the heating season). Check the motor range of the Vicki, if it is calibrated well (value between 350 and 600) and the motor position is not at Motor range value (fully closed) your TRV should be at least partially open. If this is not the case the TRV itself might be stuck (from a mechanical perspective) and you will need to fix it (for example the pin could be corroded).

My Solar Powered Device goes offline

MClimate devices using a solar panel (CO2 Display, Wireless Thermostat, CO2/HT Display Lite) can last a long time using energy harvesting (depending on the luminosity this could be indefinite), however in dim environments their operational time is limited. Move them to an area with greater luminosity. If this is not possible, make sure to top them up via the USB port and consider inserting batteries (in the case of the CO2 Display and Wireless Thermostat).

Where are my DevEUI, AppEUI, App Key?

These are sent automatically to your email inbox when you order from the MClimate store. You should receive an email from [e-mail] with a CSV file, containing the information.

If you have purchased a device from one of our distributors, please contact them directly.

In case you are unable to obtain them, still, contact us at [e-mail]

Do I need an adapter to install Vicki on my TRV?

Vicki can directly be installed on M30x1.5 TRV (in cases with a very short thread area this still might not be possible). If you are unsure of your RTVs dimensions, check our compatibility tool

https://compatibility-tool.internal.seemelissa.com/

If still in doubt mail us at [e-mail]

Is my FCU compatible with the MClimate FCT

We recommend you take a looking at he FCT Documentation page on the Applications it supports.

If you are still not certain whether it will work with your FCU, best contact us at [e-mail]

Wireless Thermostat / CO2 Display battery indicator does not fill

1. Solar power - the indicator level will depend on the luminosity, it could fill up or go down depending on how much light is hitting the solar panel

2. Batteries - depending on the type of batteries used the indicator level will increase to a set point (depending on the specific battery voltage) and decrease slowly with time.

3. USB - you will see a lightning symbol, indicating the supercapacitor (this is what actually powers the device) is charging and given enough time the indicator will fill up entirely.
