Installation or removal

Detailed information demonstrating the different ways of installing or removing a radiator heating element is available from the manufacturer or importer (see footnotes at the end of the manual). Below we list some basic requirements and principles which must be followed to ensure long term, reliable operation of the product.

TERMA MOA BLUE - Installation or removal 1

Before installation or first use:

Read the chapter Safety requirements — Installation.
Fit the heating element using the correct spanner (size 22).
The heating element must be installed at the bottom of the radiator, perpendicular to the radiator pipes, while preserving space for the proper circulation of the heating medium.
Use a suitable heating medium for filling the electric radiator, i.e. (water, special products based on water and glycol for use in central heating systems, or oil which complies with the requirements of the manufacturer of the radiator and heating element).
DO NOT SWITCH THE HEATING ELEMENT ON IF IT IS NOT FULLY IMMERSED IN RADIATOR HEATING MEDIUM (APPLIES ALSO TO THE FIRST USE)!
Make sure an adequate air cushion is present to protect against excessive pressure build up within the electric only radiator (or leave one of the radiator valves open in central heating system).
When filling the radiator with hot liquid insure that the liquid temperature does not exceed 60°C.
Follow the subsequent guidelines when connecting the electrical installation:
a. Brown wire — live connection to the circuit (L).
b. Blue wire — connect to neutral (N)
c. Yellow & green wire — earth connection (PE).
Before filling the radiator with heating medium, ensure that the heating element is fitted properly and that it is water tight.
In central heating system radiator must be fitted with the valves enabling disconnection of the radiator from the rest of the system.
The temperature of the heating agent in the central heating system must not exceed 82°C!
For detailed installation hints — see the last pages of this manual.

Notes prior to removal:

Before dismantling permanently, disconnect the heating element from the mains and ensure that the radiator is not hot.
Be aware. A radiator filled with liquid can be very heavy. When moving the radiator, ensure that you take the necessary safety precautions.
Before disassembly, close the appropriate valves and drain the radiator completely-to avoid causing any damage.

TERMA MOA BLUE - Maintenance

MOA Blue

Blue LEDs — temperature setting indicators
Temperature adjustment and Bluetooth pairing
RGB LED — TIMER, schedule and Bluetooth communication indicator
On/Off button and TIMER switch

MOA Blue electric heating element is equipped with a radiator temperature sensor (active by default!) and an additional room temperature sensor that can be activated by a mobile control application.

Turning on the unit for a specified period of time does not mean that it will receive the same maximum power at all times. The element when switched on, works at nominal power level for a short time to reach programmed temperature and then periodically turns itself on and off, consuming just as much energy as is needed to maintain the set temperature taking into account external conditions.

The heating element’s construction, as well as the physical characteristics of the heating medium, cause the lower radiator tubes (especially the bottom two) to have a lower temperature than the rest of the radiator — this is perfectly normal.

The device is equipped with a thermal fuse, which in emergency situations protects against exceeding critical temperatures (this fuse may be damaged at the temperature of 82°C — it refers in particular to heating elements installed in radiators connected to a central heating system).

The MOA can be operated using the buttons on the housing (see section Manual Operation) or via a mobile device — smartphone, tablet (see section Remote Control).

Manual Operation

(a mobile operating device with installed control application may, but does not need to be in the range)

Press briefly the key to switch on the heating element.

Use the key to set the required temperature level. It is possible to set 5 temperature levels that correspond to a temperature range of 30 … 60°C when measuring the internal radiator temperature or a range of 15 … 30°C when measuring the room temperature.

Each short press of the key increases the temperature setting from 1 to 5, the next press returns the setting to level 1, and so on.

The number of lit up, blue diodes corresponds to the selected temperature level of the device.

TIMER mode

Press and hold the key to activate the 2 hour TIMER, i.e. to dry a towel or warm up a room. Single RGB LED will turn red.

When the set time elapses, the heating element automatically returns to the settings from before the activation of the timer function. With the TIMER function active, you can freely modify the operating temperature ( key).

If the heating element was switched off prior to timer start-up, the unit will switch itself off automatically after the time elapses.

Press briefly the key to stop the timer function at any time.

ANTI-FREEZE protection

When the appliance is not in use (either off or scheduled to be off) but remains connected to the mains and the temperature in the vicinity of the temperature sensor drops below 6°C, the heating element will automatically switch itself on to prevent the heating medium inside the radiator from freezing. Activation of this function is signaled by a flashing middle blue LED.

Remote Control

The MOA Blue has a built-in and continuously active Bluetooth Low Energy communication module for remote control of the heating element, using popular mobile devices — smartphones and tablets, both with Android (min 4.4) or IOS (min 6.0) operating systems. The heating element is visible by other Bluetooth devices and appears as MOA Blue Terma. You may need to enter a default authorization code: 123456.

To start the pairing mode in MOA, press and hold for approx. 5 sec. Pairing mode is indicated by a flashing single, blue RGB LED.

Pairing mode, when activated, lasts 30 seconds.

The blue RGB LED will light up each time an active exchange of information between the heating element and an external control device, takes place.

TIMER mode

The control application allows the Timer to be set for a period of 1 … 240 minutes in the full range of temperatures supported by the heating element and any temperature measurement method — either internal radiator temperature or external room temperature. Activation of the TIMER function is indicated by a red RGB LED.

Automatic heating program schedule

The control application allows you to program many different 7-day work schedules and to upload any of the programmed schedules to the memory of any Blue heating element paired with the mobile device (see Tutorial in the control application). When uploading a schedule to the heating element’s memory, a message confirming the action appears on the portable device screen, but does not yet indicate a change in the heating element’s operating mode.

When the schedule is activated, the RGB LED lights up in green.

ANTI-FREEZE protection

Please go to Manual Operation section. A message informing about activation of the antifreeze protection will appear on your mobile device screen.
