Simple Quinta Pro boiler domestic installation
Typical ‘S’ plan, heating and hot water
(Time and temperature control by others)
Power Supply
• Boiler requires a permanent 230v single phase supply fused at 6.3 amps connected
to the factory fitted fly lead
Boiler Control Settings
(see 5.7.2 in technical documentation)
• Set boiler code P1 to the required flow temp i.e. 80 = 80ºC (system design requirements)
• Boiler will recognise the control being used
• Use the zone valve end switches to provide the volt free switch pair on OT on the main
control PCB to enable the boiler
• Boiler output will vary between 18% part load set point and 100% full load set point
to achieve the boiler flow set point (code P1)
System Components
(not supplied)
• Simple two channel time clock providing 230v switched supplies to control
heating and domestic hot water
• System pump
• Cylinder thermostat
• Room thermostat
• HTG and DHW zone valves c/w a single end switch (closes on valve fully open)
• Wiring centre
Note:
1. Maintain polarity on all connections
2. Some Neutral and Earth connections have been omitted for clarity
3. The schematic is for guidance only and does not constitute a design
4. Heating and hot water can be operated independently or simultaneously
with this layout provided the control selected will allow it
