3 INTRODUCTION
3.1 DESING & OPERATION
The Gabarrón MATTIRA CMX18i and CMX15i combi boilers
are electrically heated appliances providing wet central heating
through a standard radiator system (or underfloor system
with special kit) and domestic hot water (DHW) delivered
from an integral unvented store at mains water pressure.
Outputs are from 2 to 18kW. Maximum output can be
adjusted to match the heat requirement of the system or the
limitations of the incoming available power supply. Operation
is possible on three phase N or single phase 230V –
(Standard configuration allows a maximum of 12kW in single
phase mode).
The boilers are designed for internal installation on a suitable
wall with consideration for the total weight of the appliance
when full.
A digital control panel provides user control to adjust the
temperatures of heating and hot water. A power modulation
feature automatically adjusts the heating output to the demand
to ensure economic operation. A suitable external time
clock/room thermostat should be fitted (not supplied). All
components for sealed system central heating are built-in.
Heating and hot water functions will operate independently
but not simultaneously, with priority always to hot water
production.
