Controls
In the interest of fuel economy and user comfort, the building regulations stipulate that new installations, and systems requiring a replacement boiler, have to have adequate controls.
The control systems come under two headings known as “Minimum set” and “Best practice”, and are slightly different for Conventional and Combi systems.

●2 Cylinder thermostat.
●3 TRV’s on all radiators except in rooms with a room thermostat.
●4 Automatic bypass valve. |
Combi Systems

In addition to the above, any wireless controls should be “Radiomark” stamped to ensure that they comply with a certain level of immunity to blocking by other radio transmissions.
The above specifications are intended for gas fired domestic heating systems.
