2. Wiring to a Y plan heating system

The basic diagram below shows the main constituent elements of a Y plan  
system which is common in larger houses. The system boiler produces hot 
water which is stored in the tank and/or circulated in the central heating 
system. A motorised valve allows flow to the tank, the radiators or both 
together. A room thermostat controls the flow to the heating by opening or 
closing the valve. This thermostat needs to be disconnected at the wiring 
centre and replaced by the Boiler Switch.
