To connect the steel pipes to the system, ensure they are aligned and supported to avoid excess strain on the unit. If the system is filled with water, check all fitting seals. After ending the hydraulic connections, make sure there are no leaks Insulate the valve using the shell, fix it by means of the clips and make sure that all cold parts are insulated (see figure).
maximum height difference of 200 mm from the top of the unit (See figure). IMPORTANT Non-level installation will cause condensate dripping Do not flatten or crush the condensate drain pipe 7. Installation of the plastic diffuser Carefully unpack the assembly and check for damage sustained in transit. Attach the assembly to the unit, fastening it onto its two fixing supports (ref.
8. Electrical connections WARNING Danger to life from electric shock. Before carrying out any work on the equipment, make sure that the electrical power supply is disconnected and that there is no possibility of the unit being started inadvertently. Non-compliance with the above instructions can lead to injury or death by electrocution. The devices are operated with 230-V alternating voltage.

11. Optional Advanced wired remote controller: PAW-FC-RC1 PAW-FC-RC1 is a 230 VAC electronic fan-coil thermostat for room temperature control. It is suitable for every kind of building where reduced energy consumption and high comfort need to be met. The ability to switch between control modes depending on occupancy, makes it particularly suitable for public spaces, such as hotel rooms, offices, schools, hospitals, etc.
11.2 Dimensions 11.3 Functions The room thermostat regulates heating and/or cooling in a room via digital outputs on/off for valves and for 3-speed fan control. The touch screen shows the actual operating state and is also used to access all parameters, such as setpoint, hysteresis, fan speed etc. The unit has a built-in room temperature sensor.
The thermostat can be in one of the following states: Off: Energy stop state where the Occupied: Comfort (Standard) state Standby: Energy saving state where controller neither heats nor cools. No or if a presence detector is connected reduced heating or cooling takes background light is lit, only the On/Off and someone is in the room.
Error: short circuit or open connection at AI Check the cable between controller AI and the sensor 12. Modbus communication protocol PAW-FC-RC1 The Modbus protocol is a general-purpose protocol for data exchange between for instance control units, Building Management Systems, instruments and electricity meters. It’s an asynchronous, serial Master Slave protocol. It’s widely used, well documented and simple to understand.
