Single Quinta Pro boiler, heating with hot water priority, heating
room or weather compensated with the iSense controller
(Optimising/Weather compensated heating with timed hot water)
Power Supply
• Boiler requires a permanent 230v single phase supply fused at 6.3 amps connected to the
factory fitted fly lead
Boiler Interlocks
(for pressure switches etc.)
• Safety Interlock - remove the existing link and fit volt free switch pair to BL on the main
control PCB. If the circuit is open the boiler will go to a shut down mode displaying code
9 and will restart when the circuit is closed
Indication Controls
(to report actual function)
• Common Alarm - volt free relay on SCU-X01 (see boiler manual for full details)
• Boiler Run - volt free relay on SCU-X01 (see boiler manual for full details)
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 type of control setting used
• Fit the control in a normally occupied reference room within the building being heated.
Refer to the instructions supplied with the control package
• Set up the controller to suit the design requirements and occupancy times for heating and
hot water in accordance with the instruction documents supplied with the controller
• Install the outside sensor on a North facing wall in a sheltered position and connect to
terminals ‘Tout’ on the main PCB of the boiler
DHW Control
Diverting valve option:
Connect valve to the terminals shown, connect shunt pump PM1 to the terminals shown.
Connect valve ports AB, A and B as shown (AB = boiler, A = hot water, B = heating)
Primary Pump option:
Connect pump PM1 to the terminals shown
Connect shunt pump to the terminals shown
Note:
This option will only operate with a calorifier sensor. This is to allow the iSense to control
the hot water times.
