BOILER CONTROLS
The Quinta Ace range can be controlled using a number of
methods – other examples are given below. Scheduling using
the integral Mk3 controller in conjunction with the recommended
Outside / Room / DHW sensor when connected to the CB-03
control board. Other examples are given below. Please contact
our sales or technical departments for further options.
MODULATING (TWO WIRE CONTROL)
When using the optional Remeha compensating controllers
the heat output modulates between the minimum and maximum
value on the basis of the boiler flow temperature sensor. This
applies to both single and multiple boiler installations, under the
dictates of a room and/or outside temperature sensor.
iSense Pro
– multi-boiler multi zone optimising/compensating
controller can control up to ten boilers, two heating zones either
VT or CT and one domestic hot water circuit. Information on
the iSense Pro controller can be obtained from the installation
manual and the suggested wiring and controls schematics for
the controller.
Also, can be used as a boiler sequencer with a 0-10V dc
analogue input signal from a remote BMS controller. Managing
a primary or secondary heating circuit with up to 10 boilers.
The control is temperature dependent only i.e. 5V = 50°C flow
temperature providing lead / lag control, subject to the settings
within the controller.
iSense controller
– single-boiler (option for multiple boiler)
single zone optimising/compensating controller.
Remeha MC4
– in conjunction with the iSense controller can
provide step control for multi-boiler installation of up to four boilers.
ON/OFF VOLT FREE CONTROL FROM A THIRD
PARTY INSTALLER
Connect a two wire cable to terminal R-Bus which must
be a volt free connection from the third party controller.
Analogue control (0-10V d.c.)
The heat output modulates between the minimum and the
maximum values on the basis of the voltage supplied by an
external analogue (0-10V) input.
ANALOGUE OUTPUT - TEMPERATURE CONTROL
The 0-10V signal controls the boiler flow temperature between
0°C and 100°C. This control modulates on the basis of the
flow temperature, whereby the heat output varies between
the minimum and maximum values on the basis of the flow
temperature set point calculated by the controller sent by the
BMS e.g: 6.4V = 64ºC.
A jumper 2 (see table opposite) on the interface is used to select
either temperature control or heat output control (%).
ANALOGUE OUTPUT – CAPACITY CONTROL (%)
The 0-10V signal controls the boiler output between 0% and
100% of its total capacity (kW).
The minimum and maximum values are limited. The minimum
output is linked to the boiler’s modulation depth. The output
varies between the minimum and maximum value on the basis
of the value determined by the controller.
