Hi all
I have recently been asked to carry out some refurbishments to 120 fan coil units with one of my customers and this is not my area of expertise. They are 4 pipe units with 3 speed fan. we are requested to change the motors, filters and inspect the condition of all the 15mm pipework valves, clean internally etc from the corridor connections. They have a seperate chilled water circuit with a york chiller and a heating circuit boiler unknown.
The concern i have is that the customer has already ordered the new controls and although they are thermostat type he is requesting i replace the 4way valves with a seperate electronic 2 way valve for for both the heating and cooling coils. this will effectively just be providing full on or fully off for each coil.
Does this sound ok, or would retaining the 4 way valves be most sensible.
also any good links for correct pipework connections to fan coil units as the valves and connections are different at every fcu..
