Single Quinta Pro boiler, heating only using the iSense controller
(room or weather or room/weather compensated)
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
Fitting the Control
• For room compensation, fit the control in a normally occupied reference room within the
building being heated
• For room/weather compensation, an outside sensor can be fitted. If requiring weather
compensation only, the iSense can be fitted into the boiler control panel. In this case an
outside sensor must be fitted and connected to ‘Tout’ in the boiler on the main control PCB
• Connect the 2 wire control to the OT terminals on the main PCB. Please refer to the
instructions supplied with the iSense controller package
• Set up the controller to suit the design requirements and occupancy times for HTG in
accordance with the instruction documents supplied with the controller
Note:
The iSense controller can provide both room or weather compensation or room and
weather compensation.
Room compensation = iSense fitted in a reference room, no outside sensor
Weather compensation = iSense fitted in a boiler or plant room, outside sensor required
Room/weather compensation = iSense fitted in a reference room, outside sensor required
