Basic automatic control system for central heating and hot water production.
The system includes-:
1. one three port valve (28mm compression fittings)
2. one clinder temperature control thermostat
3. one room temperature control thermostat
4. one digital 7 day programmer
5. one wiring center
The system will fire up the boiler and allow production of domestic hot water first and then switch the boiler output to the central heating requirement.
when the room temperature is achieved the room stat will shut the boiler down and then modulate the system untill the programmer times the system off.
If required, the programmer can be advanced manually to overide the set times.
other components are required for a complete system
eg circulating pump valves and fittings.
