| of heaters or stages is equal to the number of compressors, but it is possible that the heaters or stages are less than compressors. The design of the Climma fan coil limits the water temperature to 50°C. It is therefore important that the preset value of the thermoregulator (ST2=45°C) is not increased. 2.4- Seawater circuit Check that the seawater intake is fully open and that the flow is even. 2.5 Fan coil Check that each fan coil is correctly fed with chilled water, measuring the inlet and outlet temperatures. The difference between these temperatures should be between 5 and 10° C. If the differential is higher, it normally means that there is still air in the circuit and the circulation in that fan coil is poor. In case of particularly long circuit, it might be necessary to adjust the fan coil flow closing the calibrating valves of the fan coils nearer to the manifold in order to let more water to reach the ones, which are more distant. Check that the thermostat sensor is correctly positioned in the air intake of each fan coil. If the temperature control is "Fan Only" the thermostat stops the fan when the ambient temperature reaches the set point. If the fan coil control is "Water valve" then the thermostat closes the special water valve connected to the fan coil while the fan keeps running.
