4L WIFI Under floor heating controlling system

heating controlling system
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:
controller can use:
- 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.
