Thermo Actuators: Opens and shuts valve on each group. It is controlled by the room stat in each controllable area via the wiring centre, there may be more than one group/actuator per roomstat.
Auto Air Eliminators: Removes unwanted air from the system. The air eliminators must be shut off once all the air is out of the system. Failure to do so could result in them letting by water (This will invalidate the system guarantee)
Fill/Drain points: Used when filling and testing, also for maintenance.
Pressure/Mix Temperature Gauge: Indicates the mixed flow temperature and system pressure.
Boiler Flow Temperature Gauge: Indicates boiler flow temperature.
Boiler Return Temperature Gauge: Indicates boiler Return temperature.
Flow Meters incorporating Balancing valves: Shows the flow rate through each group of pipe in litres per minute. By removing the red locking cap, the plastic indicator tube can be turned to set the required flow rate.
Thermostatic Head: Used to set the required mixed flow temperature entering the floor.
Thermostatic Sensing Element: Senses mixed water temperature and is attached to thermostatic head.
Differential Bypass Valve: Adjustable from 0.2 - 0.6 bar, this valve protects the manifold pump incase of simultaneous closing of all individual circuits.
Balancing Valve: Gives the ability to balance the flow losses of the secondary circuit (underfloor heating) with the primary circuit (e.g. radiators). The system is supplied with the balancing valve in position 2.5 which is the one that meets the requirements of most systems.
Pump valves: Isolates manifold pump for maintenance/filling purposes.
