It is sized for one room or zone of a hotel or office: valves on the Triacs, fan coil speeds or lighting on the relays, pushbuttons and window contacts on the inputs.\u003c\/p\u003e\n\u003cp\u003eThe relay block follows the F-series logic, so the 4 relays can also serve as 4 load outputs, 4 PWM valve channels, 2 shutter channels or 2 three-point valves, or be interlocked in groups of 2, 3 or 4 for 2-pipe\/4-pipe fan coils with up to 3 speeds. Inputs 1–4 accept NTC probes, up to 4 complete PI thermostat modules run inside, and 7 logic blocks handle the rest of the room logic.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e4 Triac outputs, 24–230 V AC, 500 mA each: 4 ON\/OFF or PWM valve channels or 2 three-point valve channels\u003c\/li\u003e\n\u003cli\u003e4 relay outputs 16 A cos φ 1 \/ 8 A cos φ 0.6 at 230 V AC: loads, PWM valves, 2 shutter channels, 2 three-point valves or interlocked groups of 2\/3\/4 relays\u003c\/li\u003e\n\u003cli\u003eManages 2-pipe or 4-pipe fan coils with up to 3 speeds;
