Valve Positions; Optional Electric Heating - Quartz CWM 55 Technical Manual

OPTIONAL CONTROL VALVES
2 port on/off valves or 4 port diverting valves are available as factory fitted options.
(4 port modulating valves are also available - contact TEV Technical Sales Department).
2 pipe cool only systems require one valve per fan coil.
2 pipe heat/cool systems (supplied from a reverse cycle chiller, or chiller + boiler) require one valve: if using an
auto changeover thermostat, they also need a means of signalling heating or cooling status of the flow eg a pipe
thermostat (kit shown on page 23).
4 pipe systems require two valves (but no pipe thermostat is needed).
