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.
