REMEHA Quinta Pro 30 Manual page 3

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 flow 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).
