Overview
The LCF Touch controls fan coil units and modulating (PWM) valves, on 2 pipe or 4 pipe systems. It has a 64 x 64 mm touch screen with white backlight and a built-in scheduler with seven days and four time periods. It mounts in a standard 60 mm EU box. Outputs are relays: heating and cooling, plus three fan stages. A change-over input takes an NTC10k sensor. Modbus RTU on RS485 lets a supervisor read and override it. The unit runs from 90 to 265 V AC.
