VIMAR 03989 IoT Connected Thermostatic Head User Manual

03989 – IoT connected thermostatic head
The thermostatic head, fitted directly on the radiator, regulates the room temperature by con-trolling the flow of hot water circulating in the radiators of a heating system. Thanks to Bluetooth technology connectivity, it integrates into the View Wireless system and can be controlled manually locally, by an IoT thermostat (if configured in association), or remotely via the View App or voice assistants. The IoT connected heads replace existing thermostatic heads and are compatible with most valves through the use of various adapters (see the VALVE COMPATIBILITY TABLE).

Download the View Wireless App from the stores onto the tablet/smartphone you will be using for configuration.

When the device is powered for the first configuration, we recommend you search for any new firmware and perform the update.

You will also need:

Gateway art. 30807.x-20597-19597-14597

View App for management via smartphone/tablet

Amazon Alexa, Google Assistant, Siri (Homekit) voice assistants for possible voice operation

GENERAL SYSTEM CONFIGURATION

Create your Installer account on MyVIMAR (on-line).

Wire all the devices in the system (2-way switches, relays, thermostats, gateway, etc.).
Start the View Wireless App and log in with the credentials you just created.

Create the system and the environments.
Associate all the devices with the environments, except for the gateway (which should be associated last).

For every device, set the function, the parameters and any accessory devices (wired or radio control and related function).
Transfer the configuration of the devices to the gateway and connect it to the Wi-Fi network.

Transfer the system to the Administrator user (who must have created his/her profile on MyVIMAR).

For details, see the View Wireless App manual that can be downloaded from the www.vimar.com website.

FIRST HEAD START-UP AND CONFIGURATION IN Bluetooth

Screw the thermostatic head onto the radiator and insert the batteries as illustrated in “INSTALLATION AND BATTERY INSERTION.”
After inserting the batteries, the display will show an animation in the central area:

Press the button to start calibration or wait 5 min. During calibration, the display remains off.
At the end of calibration (which takes approximately 30 seconds), the display will show the room temperature for 2 seconds and then turn off, entering standby mode.
Start the View Wireless App and view the additional devices screen.

Select “Add” ( ), choose the environment to place the head and give it a name.
Select head ; activate the Bluetooth connection on your tablet/smartphone and approach the with it.

Press the button briefly to exit standby.
Press the button again for 3 s; the display flashes twice and shows the set point after 3 s. Press buttons + and – on the head simultaneously for 6 s.

The icon starts flashing and the association is completed.

HEAD OPERATION

The thermostatic head always operates in heating mode, either ON or OFF.

Standby
When the head is in standby, its display is off. To reactivate it, briefly press the button.

Operating mode
Briefly press the button.

If the operating mode is ON, you’ll see the temperature setpoint and can also modify it.

If the operating mode is OFF, the display won’t show any value.

Temperature set point setting

When the thermostatic head is in ON mode, press one of the and buttons and they will both start flashing.
Again using + and – set the desired set point (each press increases or decreases by 0.5 °C).

The display will revert to showing the room temperature and after a 5-second timeout without interaction with the device, the thermostatic head will go into standby with the display off.

OFF → ON switching
After activating the display, press the button for 3 s.

the display flashes twice and switches ON, showing the set point and the + and – buttons.

ON → OFF switching

After activating the display, press the button for 3 s.

The display turns off and switches OFF.

N.B. After a 5-second timeout without interaction with the device, the thermostatic head will go into standby and the display will turn off.

RESET PROCEDURE.
The reset restores the factory settings.
With the head in ON mode, press the+ and – buttons until the display does not show any value.

INSTALLATION RULES

Installation must be carried out by qualified persons in compliance with the current regulations regarding the installation of electrical equipment in the country where the products are installed.
Hook the head onto the radiator before inserting the batteries and before performing configuration.

The mechanical installation of head 03989 in the radiator affects the error in the temperature measurement; depending on whether the head is installed at the base of the radiator or at the top of it, the room temperature measured can even differ by 2-3°C.
After completing installation, we recommend you perform a calibration by placing a thermom-eter in the room, at a height of 1.5 metres and at a distance of at least 3 metres from any heating elements, to detect the temperature difference between the thermometer’s measure-ment and that of the thermostatic head. If necessary, calculate the average value between the two measurement differences obtained with the radiator ‘hot’ and ‘cold’; this value should then be entered into the View Wireless App in the ‘Winter Temperature Calibration’ parameter of the thermostatic head.
The head is inserted in the Bluetooth mesh network and therefore needs at least one mains powered IoT device (control, etc.) to be within its radio range. The head cannot operate in stand-alone mode.

EXAMPLE OF USE

Climate control zone management from head
The head should be configured as independent and it does not require the creation of a group in the View Wireless App

Climate control from thermostat associated with head The ZONE 1 head should be configured as “Associated with thermostat”.
The ZONE 2 head should be configured as independent.
This type of application can only be “Winter” and is configured in the View Wireless App by creating the Climate Control group  Remote actuators and Heads  Winter  Relay
Climate control from thermostat associated with two heads and one relay for “zone consent” Configure the heads as “Associated with thermostat”.
This type of application can only be “Winter” and use one of either art. 03981, 03983 or 03985 to control the valves. In the View Wireless App, create the Climate Control group  Remote actuators and Heads → Winter → Relay
Winter circulation pump management from thermostat and/or head and one relayThis type of application can only be “Winter” and requires that at least one thermostat and head are independent.
One of either art. 03981, 03983 or 03985 should be used to control the circulation pump and a “Circulation pump” group needs to be created, including the relay and the heads. Although the presence of art. 03981, 03983 or 03985 is optional for the application, it is necessary since it is the only mains powered device that can act as a repeater.
In the View Wireless App, create the Climate Control group → Circulation pump → Winter
