I. SAFETY

Before using the device for the first time the user should read the following regulations carefully. Not obeying the rules

included in this manual may lead to personal injuries or controller damage. The user’s manual should be stored in a safe

place for further reference. In order to avoid accidents and errors it should be ensured that every person using the device

has familiarized themselves with the principle of operation as well as security functions of the controller. If the device is

to be sold or put in a different place, make sure that the user’s manual is there with the device so that any potential user

has access to essential information about the device.

The manufacturer does not accept responsibility for any injuries or damage resulting from negligence; therefore, users

are obliged to take the necessary safety measures listed in this manual to protect their lives and property.

WARNING

High voltage! Make sure the regulator is disconnected from the mains before performing any activities involving

the power supply (plugging cables, installing the device etc.).

The device should be installed by a qualified electrician.

Before starting the controller, the user should measure earthing resistance of the electric motors as well as the

insulation resistance of the cables.

The regulator should not be operated by children.

NOTE

The device may be damaged if struck by a lightning. Make sure the plug is disconnected from the power supply

during storm.

Any use other than specified by the manufacturer is forbidden.

Before and during the heating season, the controller should be checked for condition of its cables. The user

should also check if the controller is properly mounted and clean it if dusty or dirty.

Changes in the merchandise described in the manual may have been introduced subsequent to its completion on 23.09.

2020. The manufacturer retains the right to introduce changes to the structure. The illustrations may include additional

equipment. Print technology may result in differences in colours shown.

We are committed to protecting the environment. Manufacturing electronic devices imposes

an obligation of providing for environmentally safe disposal of used electronic components

and devices. Hence, we have been entered into a register kept by the Inspection For

Environmental Protection. The crossed-out bin symbol on a product means that the product

may not be disposed of to household waste containers. Recycling of wastes helps to protect

the environment. The user is obliged to transfer their used equipment to a collection point

where all electric and electronic components will be recycled.

II. DESCRIPTION OF THE DEVICE

The L-4 WiFi controller is intended for controlling the heating device. It controls the heating device and the valve actuators

which regulate the water flowing to the maximum of 8 CH zones. The device has a built-in WiFi module enabling the user

to view and edit the controller parameters using a mobile app eModul.

Controller functionalities:

controlling eight different zones using:

- wired sensor C-7p

- wired regulator R-8z

- floor sensor C-8f

- wireless sensor C-8r, C-mini, R-8b, C-8r, CL-mini, R-8b or R-8bw

- wireless thermostatic actuators STT-868 and STT-869 (max. 6 per zone)

- wireless window sensors C-2n (max. 6 per zone)

1 relay output –voltage-free contact for controlling the pump or the heating device

4 relay outputs for controlling wired floor actuators in the first 4 zones. For all 8 zones it is possible to control

wired floor valves using a wireless module MW-1.

possibility of connecting wired (zone 1-4) and wireless (zone 1-8) floor sensors C-8f.

software update via USB port.

possibility of controlling up to 8 additional contacts MW-1 or ST-981. The contact operation is based on weekly

control or control of the zones in which they are registered.

cover made of high quality materials resistant to high and low temperature.

NOTE

In zones 1-4 the user may choose the type of temperature sensor - wired or wireless (one per zone). In zones 5-

8 only wireless sensors may be used.

III. HOW TO INSTALL THE CONTROLLER

The controller should be installed by a qualified person.

1. EXIT button –exit the menu, cancel the settings, choose the screen view (WiFi, Zones, Additional

contacts).

2. –(minus) button –view menu functions, decrease the value while editing parameters.

3. + (plus) button –view menu functions, increase the value while editing parameters.

4. MENU button –enter the controller menu, confirm the settings.

WARNING

Risk of fatal electric shock from touching live connections. Before working on the controller switch off

the power supply and prevent it from being accidentally switched on.

NOTE

Sensor cables and supply cables should be connected to proper inputs.

The diagrams below show example systems:
