Note: We supply the Grundfoss 25/80 (Part No. S101621) as standard for the full Quinta Pro
range. This will alter due to changes in EU regulations. The Quinta Pro 30 will operate on speed
1, the 45 and 65 will operate on speed 2, and the 90 and 115 will operate on speed 3. They are
intended to act as a shunt pump. In the layouts illustrated, they are designed to operate on a
20ºC Delta TΔ. If using a pump without a low loss header, please take into account both the
boiler and system resistance and also when being used in conjunction with a calorifier and low
loss header. Contact our sales or technical departments for further assistance.
The hydraulic and control layouts illustrated in this brochure are for guidance only and must be
used in conjunction with the Quinta Pro and iSense Pro installation and service manuals. They
do not constitute a full system design. Remeha Commercial accept no liability for any loss or
damage rising from any errors or omissions that may be inadvertently contained in this booklet.
When connecting a control cable to the OT terminals on the main control PCB, disconnect and
remove the factory fitted lead connected to the IF- 01 PCB.
Some earths and neutrals are omitted for clarity.
All systems, mechanical and electrical, must be installed to the current regulations by a suitably
qualified engineer.

Control Options for the Quinta Pro 30 / 45 / 65 / 90 and 115 series
The Remeha range of Quinta Pro boilers are supplied as standard with an “Open Therm”
control interface which enables direct weather compensation using Remeha single and
multi boiler controls. The customer can choose to use external control options supplied
by others without affecting boiler performance.
Supplied by others
On/off control:
• Boiler requires a permanent 230v supply and is enabled using a volt free switch/relay.
The boiler will modulate its output to maintain the flow temperature setpoint,
normally 80ºC, but can be adjusted on the boiler between 20ºC and 90ºC
0-10 volt control:
• Boiler requires a permanent 230v supply and is enabled and modulated using a 0-10
volt signal from a Building Management System or quality panel mounted optimiser/
compensator. The control can be flow temperature or percentage output based
• Temperature based example: if 56ºC ow is required from the boiler, the control will need to
supply 5.6v. The output will be modulated to maintain a flow temperature of 56ºC
• Percentage based example: if the control logic requires that a boiler should be running
at 33%, the control will need to supply 3.3v to the boiler. The boiler will run at 33% output
with a variable flow temperature
• Applications - domestic/commercial and industrial installations, with a variety of heat
emitters, DHW via calorifiers or plate heat exchangers, and installations where a variety
of different temperature zones are required at the same time
Supplied by Remeha Commercial as optional extras
iSense Controller - Single/multi boiler weather compensating controller
• A simple to operate room/boiler mounted thermostat/timer which can be used with a
combination of outside/room and flow temperature sensors to vary the boiler output
(flow temp) to suit weather conditions. The iSense can be installed in a reference room
and can also be mounted in a boiler when used in weather compensated mode.
It has a 7 day timer with multiple on/off and night setback periods, holiday function,
frost protection and manual override
Celcia MC4
• Multiple boiler weather compensating controller with step control (up to 4 boilers)
to be used in conjunction with the iSense controller
• The iSense can be mounted in a reference room, in the plant room or on the boiler
• The MC4 is mounted adjacent to the boiler group
iSense Pro - Multiple boiler weather compensating controller with sequence control (up to 8 boilers)
• Optimiser compensator which can provide 2 timed heating zones and uses a combination
of outside, flow and room temperature to vary the boiler output (flow temp) to suit weather
conditions. Can also provide time control to DHW circuit. The iSense Pro controller is mounted
in a wall box when used with the Quinta Pro and is complete with timer, night setback, frost
protection and pump cycling protection. The iSense Pro controller will sequence and rotate
the lead boiler on multiple installations. This controller also has the ability to accept remote
extension timers, supplied as an optional extra, which will allow the heating system to run
on daytime compensation outside the normal timed settings without need for access or
interference to the boiler or controller. Ideal for school lettings/night classes etc.
Note: We do not advise using a combination of external and built-in controls as in most cases
there can be no interface between them; it is likely they will ‘conflict’ with each other
and neither will work properly. The exception to this is when using the iSense Pro kit KT1154
in conjunction with a Remote BMS controller (see page 31).

• For room/weather compensation, an outside sensor can be tted. 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 tted in a reference room, no outside sensor
Weather compensation = iSense tted in a boiler or plant room, outside sensor required
Room/weather compensation = iSense tted in a reference room, outside sensor required

Multiple Quinta Pro boilers, heating only, outside weather or room
compensation with the Celcia MC4 and iSense controller with a low
loss header (Optimising/weather compensated)
Power Supply
• Boilers require 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 t 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)
Fitting the Controls
• Fit the iSense controller in a normally occupied reference room within the building being
heated if room and weather compensation is required. If weather only is required,
the iSense can be fitted in a boiler control panel. Install the MC4 controller adjacent
to the boiler plant and connect as shown
• Install the outside sensor on a North facing wall, and connect to the MC4
(for weather compensation only)
Boiler Control Settings
(see 5.7.2 in technical documentation)
• Set boiler code P1 to the required ow temp i.e. 80 = 80ºC (system design requirements)
• Boiler will recognise the type of control setting used
• 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: Installation can be designed without the use of a low loss header. Omit the header and
shunt pumps. A heating pump must be capable of overcoming the combined resistance of the
boiler, system and pipe work.
A reverse return with a common loop and single primary pump would be suitable.

valve or primary pump kit, the calorifier must be sited within 3m of the boiler. In both cases,
the hot water calorifier must be a high recovery unit capable of accepting the full or adjusted
hot water output of the boiler being used (reference parameter P18)
• Set up the controller to suit the design requirements for the hot water times and temperature

iSense Pro Controller Kit Options
The options illustrated show the four types of controls available. The difference
with the first three kits depends on which type of internal sensor/control is used.
KT1089: the basic internal sensor, no adjustment is available
KT1090: the inside sensor can be used to adjust the room temperature
KT1091: includes a digital remote control which not only acts as a sensor but changes can
be made to the main controller which includes set point temperatures and it can also override
the time settings on both heating and hot water
KT1154: can be used as a boiler sequencer. Will require a 0 - 10v input from a remote
BMS controller
KT1152: required when using more than two boilers (one kit per added boiler up to eight boilers)
e.g. six boilers will require four KT1152
Fitting and user instructions are supplied complete with the iSense Pro kits. The controller is
suitable for 2 - 8 boilers and will time control two zones (optimising and compensating) and
also control temperature and time hot water (note hws control is via a sensor not a thermostat).
Note: The OT cable between the iSense controller and the first boiler is not supplied.
Cable should be 2 core .7mm² (screened when running with higher voltage cables)

Multiple boilers, heating and hot water using a low loss header with
the iSense Pro controller (Optimising/weather compensated control
for dual heating zone and hot water from all or single boilers)
Power Supply
• Boilers require 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 t 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 codes P1 to the required ow temp i.e. 80 = 80ºC (system design requirements)
• Boiler will recognise the type of control setting used
Fitting the controls
• Use the following hydraulic and wiring diagrams to best match the building requirements
• Fit the iSense Pro in the supplied wall mounted box adjacent to the boiler plant
• Connect all chosen auxiliary controls i.e. pumps, 3 way valves, outside sensor, ow sensors
etc. as indicated
Control Logic
• Set up the iSense Pro controller in conjunction with the iSense Pro installation and service
manual and to suit the installation and building heat loss response time. It will provide timed
weather compensated heating with an optimum start facility (uses inside and outside
sensors to delay the on time as dictated by weather conditions)
• Heating (all boilers available): during the timed on periods the heating will be daytime
weather compensated (in accordance with the heating curve programmed). The controller
will directly control each boiler, modulating their output and calling as many as are required
to achieve the desired comfort conditions dictated by the compensation parameters
• Hot water: two hydraulic options are available as shown in the diagrams. When using
the single boiler option, the hot water controls, i.e. the pump and sensor, are taken to
the boiler controls. A separate volt free time control will have to be used (not supplied
by Remeha Commercial)
• The following diagrams QP009 to QP009E show systems with two zones.
If only using a single zone, use zone B controls and omit zone C controls
Kit KT1154 will enable the iSense Pro controller to operate as a boiler sequencer. This will
require a 0 - 10v input from an external source i.e. BMS controller. The iSense Pro will control
the boilers to achieve the setpoint temperature supplied from the BMS control i.e. 5v will equal
50ºC. How the iSense Pro will sequence the boilers (lead/lag etc) will depend on how the user
control parameters are set within the iSense Pro controller.
